Title:Spectral Cueing/Spatial Confirmation Targeting
Abstract:The objective of the Phase I Fast Track SBIR is to develop a common optic system that will allow the capability to perform wide FOV spectral cueing and narrow FOV, spectrally enhanced, spatial confirmation on military targets of interest. Spectral resolution should be on the order of 1nm in the visible. Due to the importance of the effort, SOC has already identified a qualified Phase II partner to support our effort. The SOC team including RAI, TRA and CEB Metasystems has designed and built several common fore-optic systems under other activities (i.e., LASH and Low Cost Missile projects) which have been designed to peform wide FOV spectral cueing and narrow FOV spatial confirmation on military targets of interest, and will utilize a unique PGP spectrometer and MIDIS real-time HSI processor technology to successfully field a tower based HSI/MSI/HRI, CC&D target detection ATR experimental sensor system. To satisfy the objective of the Phase I program, the SOC team will conduct the following tasks: (1) Develop common optic system requirements; (2) Conduct a tower field sensor system tradeoff study; (3) Define the tower sensor test objectives; (4) Deliver a tower and operational sensor software testbed; (5) Conduct a tower sensor design; (6) Identify potential sources of capital for commericalization; and (7) Provide reporting. Completion of these tasks will satisfy the objective of our program, "to develop a common optic system that will allow the capability to perform wide FOV spectral cueing and narrow FOV confirmation on military target of interest", by utilizing the available SOC MIDIS and RAI PGP spectrometer technology to facilitate successful development of a common fore-optic sensor for real-time spectrally enhanced ATR demonstrations. The effort will develop the technical underpinnings for real-time HSI/MSI/HRI sensor and processing techniques for wide FOV spectral cueing and narrow FOV agile spectrally enhanced, spatial confirmation on military targets of interest with a high success rate utilizing a common fore-optics system; and by modeling a simulation with available HS/MS imagery data provide the expected performance for various applications so as to be able to define a realistic detail Phase II plan for the development and demonstration of the targeting system and for applying this to planned systems for dual-use applications. The program will provide the technology background to be able to design and develop the next generation high performance real-time HSI/MSI enhanced ATR instruments heretofore unavailable, benefiting not only the Services, but also industry. The common optical system developed under this topic could be applied to a range of planned commercial HS remote sensing systems for both commercial and military applications. Potential military applications include CC&D target detection and identification, terrain/trafficability analysis. Potential commercial applications include remote sensing for geological, land use monitoring, agricultural, and mineral exploration purposes.

Title:No-Power MEMS Trigger Sensors for Missile Health Monitoring
Abstract:To reduce total life cycle costs of Army munitions, state-of-the-art health monitoring technologies are being applied in the diagnosis and prognosis of missile system health. Due to size and cost, MEMS technology has the potential to enable advanced health monitoring systems. However, energy storage is at a premium, and even though MEMS devices consume extremely small amounts of power, the power budget is still too tight to easily meet system requirements. Therefore, the use of no power sensors and limit detectors is potentially invaluable in the development of low-maintenance health monitoring. This proposed Phase I effort will determine the feasibility of a particular no-power transduction mechanism that can be applied to inertial, chemical, temperature, and humidity sensors. The approach can result in advanced functionality including device arrays, programmable limits, and settable latching modes. This first phase will develop simulations and perform proof-of-principle experiments to verify the approach. In addition, designs and process flows will be developed in anticipation of a Phase II award. Phase II will then prototype, package, and integrate a sensor array into a health monitoring system. The MEMS devices proposed in this effort have a number of military and commercial applications. As individual devices, they would find application as trigger sensors for packages in transport, food, and health monitoring systems for missiles, rotary- and fixed-wing aircraft, automobiles, and other high-value assets. When implemented as arrays, the devices could function as triggerable electronic noses and wide dynamic range discrete-value environmental sensors.

Title:New Approach to Wave Oriented Radio Propagation Modeling
Abstract:Wireless communication systems are normally designed and optimized for line-of-sight propagation. In reality, however, the propagation scenario may be very complex involving a multitude of terrain features and obstacles, which generate multipath reflection, diffraction and scattering. An accurate evaluation of the communication channel performance would not be possible without a detailed knowledge of the physical features of the propagation medium. This Small Business Innovation Research project proposes a physics-based approach to channel propagation modeling. The input to the model is a database that includes topographical information, terrain features, natural and man-made scatterers, etc. A user friendly software environment will be developed to interface the physical database with an advanced ray tracing code enhanced with a comprehensive library of full-wave scattering and diffraction models. Special emphasis will be placed on polarization characteristics, fading statistics and spectral and temporal decorrelation of the channel. The proposed software package will be used for evaluation of channel performance and reliability in military mobile distributed networks as well as palnning of commercial communciation system.

Title:New Approach to Wave Oriented Radio Propagation Modeling Based on Extended FDTD Methods
Abstract:Predicting the signal level and coverage area of radio frequency communication channels between base stations, vehicles and warfighters is a challenging problem. The channel may involve radio frequency interactions with hills, foliage, and buildings. The paths may involve long distances over hilly terrain or shorter distances involving interaction with urban building features. Some propagation paths may simultaneously involve hills, foliage, and urban areas. Existing methods for making physics-based predictions of radio propagation are limited to single classes of interactions, such as urban, terrain, or indoor. And even though physics-based, require approximations and assumptions that limit accuracy. In this effort it is proposed to extend the Finite Difference Time Domain (FDTD) method to allow full wave calculation of long distance radio propagation over irregular terrain. Remcom has already developed a commercial quality radio propagation prediction model based on high frequency ray methods. Future plans include extending the capabilities of this software to include more accurate propagation prediction over irregular terrain including area coverage, and to mixed paths. The proposed effort should result in the most accurate irregular-terrain propagation model available. At present there is no commercial software network planning tool that will accurately predict radio propagation over irregular terrain, or over paths that simultaneously involve irregular terrain and urban features, or urban features and indoor locations, or any combination of these. The market for such a software product is large, including both commercial and DoD applications.

Title:Tracking Dynamic Sources For Sonar Signal Processing
Abstract:Sonar performance is characterized by its ability to distinguish intended targets from background noise. Background noise includes both ambient noise in the ocean and interference from non-target ships. Non-target ships present moving noise sources which are not adequately suppressed by existing techniques. This project will estimate the extent two existing technologies can suppress moving noise sources. First, methods from mathematical finance will be used to model the time varying covariance of sonar noise, which is the key element of sonar detection with moving noise sources. Second, a multi-target tracker will be integrated with the signal processing to provide an explicit model for moving noise sources. We will evaluate the improvement in signal gain and interference rejection from these techniques. The proposed project will improve the ability of Naval sonar systems to detect moving targets in the in the presence of moving acoustic interferers. Commercial applications include identification of dynamic factors for financial analysis.

Title:Processing Techniques for Dynamic Sources
Abstract:This research is directed toward the Navy's current ASW problem, detecting quiet diesel-electric and air independent propulsion (AIP) submarines in littoral regions where today's systems are ineffective due to interference from many loud moving surface ships. New algorithms will be developed that are effective for this nonstationary problem, rejecting multiple loud moving interferers while simultaneously improving signal matching for a quiet moving target. In addition, we will develop absolute bounds on the performance that can be achieved by any algorithm. The approach involves analysis and simulation of structured scenarios of increasing complexity to isolate specific effects and provide insight and understanding. This work builds on ORINCON's extensive experience with adaptive beamforming and leading role in recent efforts that address the nonstationary problem. It takes advantage of an existing simulation capability to permit rapid progress with limited resources. Algorithms developed in Phase I will be demonstrated on sea test data recording using a real-time implementation in Phase II. A subsequent transition to the Navy via the Advanced Process Build (APB) program is planned. The new algorithms will also be applicable to nonstationary problems in radar and wireless communication. This research will provide new adaptive algorithms that are effective in nonstationary environments. Simulation scenarios will be developed along with performance bounds that can be used as benchmarks for other algorithms. Results will be applicable to nonstationary problems in bistatic radar and wireless communications, as well as for passive sonar.

Title:RF Polymers for Integrated Sensors
Abstract:Beltran proposes to develop a new advanced technology for the fabrication of magnetic polymers. One of the possible ways to provide the values of magnetic characteristics required for electronic applications of polymer materials is to utilize polymer materials in the form of magnetic nanoparticles incorporated in easily available organic polymer matrices. The necessary magnetic and resistance properties can be controlled by the properties of the incorporated nanoparticles, the matrices and their bonding. Thus, the main technical objective of the Phase I effort is the development of a new approach for the fabrication of magnetic metamaterials with radio frequency (RF) properties suitable for application to integrated RF sensor technologies and superior to conventional ferrites by creating magnetic polymers involving nanoparticles of various magnetic materials. The advanced magnetic and resistance properties will be demonstrated by direct measurements of the materials prototypes. The anticipated benefits are: possibility of producing large quantities of bulk magnetic polymers; stability of organic polymer matrix in the most hazardous operating conditions; light weight of the materials (at least 2.5 time less than currently utilized materials); possibility of fabricating magnetic polymer materials with advanced radio frequency properties suitable for application to integrated RF sensor technologies; easily machinable; possibility of developing these technology methods for other requirements. The potential commercial applications are the fabrication of magnetic metamaterials for radio electronic components, radiation shielding, magnetic refrigeration, magneto-optical memory, polymer wave-guides and amplifiers and magneto-electronics.

Title:RF Polymers for Integrated Sensors
Abstract:Polymer composites have had an important role in radio frequency (RF), microwave, and millimeter-wave (mm-wave) engineering. These materials offer good mechanical and electrical properties. However, the excellent properties of conventional polymer composites are not ideal for use at RF frequencies. Recent innovations in polymer composite engineering has provided the possibility for engineered materials with tailored mechanical, thermal, and electrical properties. The goal of this proposed research project is the investigation of potential polymer composites that exhibit magnetic properties and to find specific applications in integrated RF apertures. Computational electromagnetic tools will be adapted for this effort and exercised to determine electrical properties for an example aperture and an extensive literature search will be conducted concerning the modification of electrical and especially magnetic properties. The MRC team has expertise in all aspects of the proposed project including military RF applications, computational electromagnetics, composite polymer engineering, and microwave-grade ferromagnetic materials. In the proposed Phase I effort, the MRC team will identify optimal polymer and magnetic materials. In addition, optimal material properties will be defined, and a proof-of-concept research program including coupon fabrication, property testing, and aperture design/fabrication/testing will be proposed for Phase II. A new class of integrated apertures using ferrite loaded composite materials will have many applications in both military and commercial communications, wireless, and RF systems. Shared apertures, wideband applications, as well as new types of low cost, lightweight antennas with low physical or conformal profile have a large potential market in wireless network environment. MRC will vigorously pursue all potential applications of the antenna and systems technologies resulting from a successful result of the proposed research.

Title:Gun Launched Guided Projectile
Abstract:Ensuring U.S. technological superiority over potential adversaries through the use of emerging technologies to improve warfighter lethality, survivability, and mobility is central in the effort to maintain effective fighting forces. Conventional medium caliber projectiles fall short of desired effectiveness due to many physical and environmental factors such as aiming inaccuracy, component manufacturing tolerances, wind effects, etc. A guided projectile that could eliminate these factors at long (or short) ranges would substantially improve hit probability, increasing effective range and lethality. Longer standoff distances also contribute to higher warfighter survivability. Further, increased lethality of smaller caliber weapons contributes to greater force mobility. The objective of this Phase I effort is to develop a technically feasible concept for a medium caliber guided projectile and its guidance and control system. Our approach exploits recent advances in 'smart' material development to provide an innovative projectile flight control mechanism driven through a very simple communications link to its weapon-based transceiver. The flight control mechanism's simplicity and robust configuration offers high survivability for the severe launch and flight conditions anticipated. We propose a 25 mm diameter projectile to highlight its simplicity and compactness, though the concept readily scales to the full range of interest (12mm to 40mm). This guided projectile will significantly increase effective range and lethality over currently available munitions, with direct application to a broad range of existing military and law enforcement weapon platforms.

Title:Power Genaration for Gun Launched Interceptors
Abstract:The project has the objective of studying the feasibility of a number of novel methods and concepts for electric power generation for high-speed guided gun-launched interceptors and other similar projectiles. A number of the electrical power generation concepts are integrated into the structure of the projectile. As the result, all or a significant portion of the space required to house an equivalent power source can be saved. In addition, the electrical power generation device and its related components are better protected against high acceleration loads, vibration, impact loading, repeated loading and acceleration and deceleration cycles that can be experienced during transportation and loading operations. The emphasis of the project is on the development of electrical power generation devices for supersonic, highly maneuverable, gun launched, guided medium caliber projectiles that are subjected to high firing acceleration loads. The advocated electrical power generation designs that are highly resistance to shock and impact loading greatly reduce the power source space requirement, thereby increasing the space available for electronic and guidance and control gear and payload. The designs would also have commercial application for all disposable electronics and communication devices, particularly those that have to be protected against possible impact and dropping of the device.

Title:Multi-Modal Command Interaction
Abstract:This project attempts to develop an architecture that will enable us to transition multimodal (speech and sketch) technologies for a variety of C3I tasks to the DoD. For example, users will be able to create courses of action, collaborate with other users, invoke simulators, etc. by speaking and sketching on tablet computers, PDAs, wearable, wall-sized, and paper-based systems. In virtue of a multiagent architecture and interoperation frameworks (e.g., the CoABS Grid), advanced interface technologies will be able to interoperate with DoD information systems. Phase I will involve analysis and extension of our multimodal architecture, particularly to support "intelligent paper." It will also involve designing experiments to assess the strengths and weaknesses of multimodal technology in the field. Phase II would then involve further development of the multimodal architecture and conduct of those experiments. If this research and development effort is successful, warfighters will be able to interact with command and control systems using speech and sketch. They will be able to do so in a variety of circumstances, and with equipment in a variety of form factors. Notable among these are tablet computers, PDA, and intelligent paper. The latter will offer ultra portability, the resolution and well understood failure modes of paper, but will also offer the benefits of digital systems. Users will be able to save substantial time in interacting with existing C3I systems, such as MCS, and will be able to transition from a method in which both paper maps and computer systems are used. Rather, employing just "intelligent paper," the user will be able to get both sets of advantages simultaneously, thereby halving the workload. Thus, we anticipate being able to overcome warfighters' resistance to adopting digital systems by providing an interface that does not fail, and engenders confidence.

Title:Incorporation of Commonsense Reasoning of Geographical Spaces and Advanced Computer Visualization for Voice Controlled Map Sketching
Abstract:The goal of this Phase I research project is to develop an integrated system to enable multi-modal input, allowing a participant to use spoken commands to create and edit map sketches. The project will develop an architecture for multi-modal interaction, perform initial experimental validation, and develop a set of metrics and an experimental paradigm for demonstrating the strength and weaknesses of the proposed technology. The Phase I research will evaluate the performance and usability differences among the modes of input for different sketch creation tasks, with a particular focus on speech commands. The research will also explore the use of a speech recognition approach that exploits commonsense knowledge of geographical spaces for a particular set of command tasks (e.g., via incorporation of Nave Geography based reasoning). The ultimate goal is to synergistically combine this spatial reasoning with sketch understanding to support course of action's planning, editing, and monitoring within a multi-modal command post. The first targeted commercialization sector for this technology is the area of multimodal command interaction in military command posts. This technology will also be extremely applicable to all other areas where instructors or knowledge workers might wish to incorporate illustrative sketches, animations and who desire a more fluid interface to their presentation creation tool.

Title:Biofilm Capture of Chemical Warfare Agents
Abstract:The potential use of biological and chemical warfare agents presents a threat to both military and civilian communities. Improved methods of capturing and detecting these agents are needed to increase public safety and protect military personnel. Biofilms may be one answer to this problem. Biofilms consist of microorganisms growing on a surface and enmeshed in a polymer matrix. Observations of many biofilms in a variety of environments suggest that they have a natural ability to bind a wide range of organic and inorganic substances from their surroundings. This property of biofilms may be exploited to improve the detection of chemical and biological warfare agents. The ability of biofilms to concentrate trace quantities of hazardous substances will result in improved detection techniques. The research proposed herein will evaluate the ability of biofilms to capture and concentrate potential chemical warfare agents. Recently there has been significant research into detection of biological and chemical warfare agents. However, much less effort has been put towards collection and concentration of these agents. This is the primary benefit of biofilm technology - an inexpensive collection system that uses a natural biofilm to collect a toxin or pathogen in quantities that can be readily measured. Rather that taking samples periodically, the biofilm capture system could be "on line" at all times, continually collecting "data". Potential commercial applications for this technology include the monitoring of drinking water treatment and supply systems for both public utilities and the military. This inexpensive technique could be used to guard against pathogens and hazardous chemicals in drinking water supplies worldwide.

Title:Fracture-Initiated Hybrid Adhesives for Self-Repairing Composites
Abstract:Novel fracture-initiated adhesive materials are proposed for fabricating thermally stable, polymer matrix composites with the ability to repair themselves after sustaining structural damage. The proposed research explores the feasibility of modifying conventional thermoset resins with microencapsulated hybrid monomers that upon matrix fracture, spread to the damaged area and stabilize the structure through ambient temperature polymerization. The main objective is to develop an easily processed resin system with strong adhesion to reinforcing fibers, high thermal stability, robust reactivity over a wide temperature range, and the ability to recover mechanical properties after being damaged. The proposed microencapsulated hybrid monomers cure by a combination of chemical processes by contact with matrix-embedded low cost catalysts. The resulting repair resins will exhibit equivalent thermal stability to the original matrix resin system. In the proposed study, the candidate materials for these resin repair additives will be identified, a new type of inorganic-organic hybrid monomer synthesized, structure-property profiles determined and the ability to cure into useful materials by fracture-induced initiation demonstrated. Mechanical properties of candidate composite specimens and controls with glass and graphite fiber-reinforcements will be measured before and after impact-induced damage and compared. Procedures for applying this technology to aerospace-grade composites will be prepared. The benefits of an easy-to-process, impact resistant composite having the ability to repair itself after sustaining damage include higher survivability, excellent environmental durability, improved mission readiness and lower maintenance costs. Potential commercial applications lie in the manufacture of structural aerospace components for both military and civilian markets as well as for automotive applications.

Title: Lightweight Man-Portable Winch
Abstract:Urban warfare tactics call for clearing buildings from the top down. Roof access is greatly improved by a lightweight, efficient winch. The devise generates 1-2 hp, lifting soldiers with fighting load (~ 100 kg) at a rate of 1 meter per second. Radiated noise is less than 50 db. It will be as efficient as possible to minimize the fuel consumption and thermal signature. We will conduct an engineering feasibility investigation for the lifting system with the use of computer analysis of system elements. Trade studies will evaluate three system approaches to the portable lift. The preferred approach for the power supply is Quoin's PowerQuickTM free-piston-based micro-engine; currently under development as a primary power source for DARPA. The high-pressure gas from the power source drives a small turbine internal to a winch. Studies will focus on the design and integration of the winch along with implementation of the operator interfaces. A preliminary concept for a small 3-pound device clamps on a mountaineer's climbing rope. It has an integral power, turbine drive, operator control interfaces. This device is to be demonstrated in Phase I. An interesting variation of the concept features a belt mounted power supply that can power many tools. Quoin has teamed with commercial manufacturers to design versions of the power supply for use in portable nailers and firefighting equipment. Work will expand to include additional civilian and military applications.

Title:Use of Light Emitting Diodes (LED) in Pathogen Elimination, Wound Healing and Tissue Regeneration
Abstract:In the published scientific literature, various articles have described the process of "photobiostimulation". This process involves the irradiation of tissue with infrared light sources resulting in the improvement in such conditions as wounds and arthritis. Some authors have described the improved healing of wounds and arthritis not only at the irradiated sight but also on contralateral limbs. These findings suggest the presence of a humoral substance which may be formed as the result of tissue irradiation by infrared light. This experiment will use an animal model to identify the presence of such a humoral substance. At baseline a blood mass spectography will be measured then subjects will be irradiated with infrared light and repeat mass spectographic measurements will be taken and compared to baseline. Several different infrared wavelengths and power densities will be compared. Bilateral wounds will be created on each subject and on control group. Comparison will be made on wound healing times between the groups and between the contralateral wounds. Also, the presence of wound infection will be noted, if it occurs, and compared between groups. The identification of the formation of a substance with tissue healing effects due to the application of infrared light is a groundbreaking discovery. The further elucidation of the substance could have profound therapeutic benefits in a wide variety of potential applications such as wounds, burns, degenerative musculoskeletal disorders and cancer. In burn injuries for instance, light therapy (or the substance) may prove far superior to conventional treatments and skin grafting. Also, in a military setting combat personnel in the field could possibly benefit from the immediate application of light therapy to wounds or burn injuries. This equipment could be designed to be portable, lightweight and capable of withstanding the rigors of the operational environment.

Title:Photodynamic Decontamination and Biostimulation System
Abstract:In response to DARPA's request for a new technology that provides: 1) rapid detection and elimination of pathogens in contaminated traumatic skin wounds (including thermal, radiation and chemical burns) and 2) accelerates wound healing in a sterile environment using light emitting diodes (LED), Physical Optics Corporation (POC) proposes to develop a unique Photodynamic Decontamination and Biostimulation (PDB) system. The system is based on the topical application of lipid-coated microbubbles (LCM) enclosing Methylene blue as a photosensitizer and illumination of the wound with two NASA light-emitting diode (LED) arrays. One of the LED arrays is used for photosensitizer excitation and generation of antimicrobial reactive chemical species. The second array will produce a powerful biostimulating effect on wound healing. LCM formulation of the Methylene blue allows eradicating both extra-and intra-cellular pathogens. Decoloration of a small portion of the dye (released from the LCM during light irradiation) will indicate the presence of a pathogen and/or an active inflammation. The PDB system integrates three major components: an LCM generating subsystem, an LED array subsystem, and a transparent wound bandage. In Phase I, POC will demonstrate the PDB system's ability to eliminate pathogens and stimulate wound healing within vitro experiments. The successful completion of this project will result in a reliable, portable, and cost-efficient device using a novel technology for open wound decontamination and treatment, which's also suitable for a wide range of commercial applications, notably treatment of serious burns, crush injuries, traumatic ischemic wounds, radiation tissue damage, compromised skin grafts, and hospital infection.

Title:Use of Light Emitting Diodes (LED) in Pathogen Elimination, Wound Healing and Tissue Regeneration
Abstract:Enhancing the soldier's tissue responses to injury may lead to battlefield resilience and medical independence. Counter-measures to chemical, biological and radioactive weapons exposures, which are based on biostimulation of natural tissue regeneration mechanisms, could be more universally safe and effective than conventional drugs and surgical modalities. Regeneration of wounded organs and limbs may also be possible if biostimulation could reawaken molecular events leading to re-growth of tissue. We are now investigating applications of LED wound healing technology for self-care of the soldier. Several uniquely military situations and indications could be addressed, optimizing near-IR parameters for wound healing via LED's during extended missions, under conditions in which the soldier is separated from medical personnel. This DARPA funded SBIR will begin work to dramatically enhance biostimulation using this LED-technology with a project focused on rapid healing of retinal laser-injury. There is no doubt that this type biostimulatory enhancement, once demonstrated, can be immediately applied to military applications and will have profound economic implications for the health care industry. With the development of a low cost LED source, this technology will no doubt find its way into rural area medical facilities thereby making the technology readily available to everyone. The world wide commercial implications for this device technology are enormous.

Title:Gallium Nitride Based Light-Emitting Diodes (LED) for Pathogen Elimination, Wound Healing and Tissue Regeneration
Abstract:Rainbow Communications proposes to investigate a compact, high-output-power, cost efficient, light-emitting diodes (LED) based on III-V nitride materials, quantum-well, and a tapered-optical-amplifier structure for applications in pathogen eliminations, wound healing, and tissue regeneration. The LED will be capable of producing more than 50-mW output power in the UV and/or visible wavelength region. Several unique features distinguish it. First, Rainbow will monolithically integrate a light emitting waveguide, and a tapered optical amplifier into a INGaN/AlGaN quantum well substrate. Second, a tapered waveguide structure will increase the coupling efficiency between the LED section and the optical amplifier section, and improve the optical amplifier efficiency. Third, by providing different wavelengths and broad-beam characteristics, the LED source will be a superior method for wound healing and tissue regeneration comparing to traditional suturing or lasers. Forth, the LED source can be used to excite visible fluorescence from the light sensitive detergent, thus providing the residual distribution of pathogens. In Phase I, Rainbow will demonstrate the feasibility of the proposed Gallium Nitride (GaN) LED source for medical usage. In Phase II, a LED source based sensing, decontaminating, and regenerating system will be developed and demonstrated under in vivo stimulation of tissue growth condition. This project will enable development of a compact, low-cost, reliable, highly efficient, high-power LED source for use in pathogen eliminations, wound healing, and tissue regeneration for wounded soldiers caused by chemical, biological, thermal, and radiation burns. The resulted products can be used in effective sterilization of contacted surfaces in a medical treatment facility without any residual chemical by-products.

Title:Electronic Market-Based Decision Support
Abstract:Net Exchange proposes a Phase I DARPA SBIR study into the use of combinatorial information markets as decision support tools. The specific application studied will be the estimation of international military instability. The efficiency of U.S. troop deployment can be significantly improved if better estimates of international stability can be made. We will test whether information markets can do this. International stability, as well as many other military and commercial applications, involves the estimation of separate events that are, none the less, complexly inter-related. To provide probability estimates of interrelated events, an information market must be able to handle conditional probabilities. Simple information markets, exemplified by the Iowa Political Stock Exchange, do not and cannot deal with conditional probabilities. A combinatorial market can. In the case of an information market, this functionality is precisely what is needed to handle conditional probabilities among future events. The founders of Net Exchange, while still at Caltech, designed, built, and operated their first combinatorial market in 1992 to assist NASA in R&D resource allocation for its Cassini Saturn mission. The firm was spun out of Caltech in 1994 and has since been a pioneer in the development and commercial use of combinatorial markets. Information markets based on combinatorial processes offer promising solutions for problems and concerns within the DoD and the private sector. Within the DoD, information markets can augment the extensive wargaming activities undertaken by the various services and other DoD functions. In this role, the information market pools the opinions of a broad array of spectators and can be used to compare the actions taken by the wargame participants with the predictions formed from the aggregation of spectator opinions. An information market that can handle conditional probabilities among interrelated and contingent actions provides the level of detail needed in this sort of wargaming application - such functionality is exactly what combinatorial processes bring to an information market. Also within the DoD, but directly affecting actual military operations, is the potential to apply information markets to allocating operational resources. An operational extension of the international military instability application proposed in this proposal could be used to help direct the strategic positioning of resources. More sophisticated and dynamic combinatorial information markets could be used for increasingly fine tactical situations, including, in the extreme, battlefield management functions. Within the private sector, combinatorial information markets offer great potential for improving the management of certain key business processes. The management of a portfolio of internal research and development (R&D) efforts would be a high-valued and rather straightforward application of a combinatorial information market. As the critical information required to make the portfolio decisions is held by the researchers involved with each effort while the portfolio decisions must be made by levels of management above these researchers, an information market is motivated. Many industries have similar R&D structures and many business processes in addition to R&D can benefit from combinatorial information markets.

Title:Robot Beacon Module for Minimum-Resource
Abstract:iRobot Corp. has already developed an infrared communication, robot location, and obstacle detection system called ISIS and incorporated it into a swarm of robots. ISIS provides two degrees of angular resolution, a communication range of up to eight meters, and a 125 kbits/sec data rate. It has a total cost of approximately $150, and measures 3.5" x 3.5" x 1". The proposed design will miniaturize ISIS to 1/50 the current volume (the size of a checker piece). It will reduce the cost to be on the order of $10 in large quantities. It will extend ISIS' capabilities to have one degree angular resolution (using eight detectors), and will be modulated for better noise rejection and greater dynamic range (up to fifteen meters). We expect to provide a low-cost, complete infrared communication, robot location, and obstacle detection system on a single chip. This will enable mass producible swarms of robots for use in research, toys, home and industrial applications. It is a key for future research in swarm technology and will allow development of highly-scalable homogeneous and heterogeneous distributed robotic systems.

Title:Omnidirectional Robotic Beacon-eye
Abstract:DARPA is seeking to develop an advanced omnidirectional beacon-eye for robotic applications. Physical Optics Corporation (POC) proposes to develop a new compact Omnidirectional Robotic Beacon-eye (ORB) based on a solid panoramic head, which will transfer an input area of 7 in elevation and 360 horizontal to a conventional conical input field where it can be imaged to the receiver. In the reverse path, the receiving beacon-eye can be used as a beacon. The special orthogonal grooved structure can provide retroreflection of incoming beams. This allows members of the robotic team to use another robot for triangulation even if the other robot is disabled and without power. The proposed ORB offers several advantages including compact design involving eye, beacon and retroreflection in one device modular design easily mountable on the robot and low cost. In Phase I POC will design, fabricate and evaluate the prototype of the proposed ORB. In Phase II the beacon-eye will be integrated and tested in an actual multicommunication scheme. The proposed robotic beacon-eye can be used in the commercial sector in a variety of multicommunication schemes including security systems, law enforcement and many other current and future potential applications.

Title:Interaction with Experiences
Abstract:DARPA recognizes the need to capture and transform human experience and, based on those experiences and incoming information, develop a schedule of actions to augment the cognitive abilities of humans. One reason for capturing human experience is to alleviate the increasing number of demands on the warfighter who has a limited cognitive capacity. Another reason for capturing human experience is to allow knowbots to perform the work of the warfighter on the battlefield. GroupSystems.com proposes to conduct a feasibility analysis for an integrated online open-architecture software environment that will augment the cognitive abilities of warfighters as they work individually or together, assisted by knowbots, to make sense of circumstances and control events on the distant battlefield. We believe that by doing so, we can better prepare the warfighter so that he can take a proactive rather than reactive role on the battlefield, improving his chances of survival. Any industry that can benefit from improved group dynamics, can benefit from BattleSpace. This is because the product suite will be flexible and scalable, making it ideal to develop customized products. One can add domain specific behavioral knowledge through unique authoring tools, ensuring a tailored environment to support group work.

Title:Interaction with Experiences
Abstract:This project proposes to transform studied brain wave patterns into experiential criteria for interpretation and understanding of human interactions with and by computer systems. The study aims to simulate the steps of interpreting pre-existing brain wave patterns, for various AI techniques to interpret and store maps of experience. Interpretation will be made by human monitors to facilitate the transitions from brave wave pattern to each stage in the computer system. The inevitable progression, in later research, will be to remove the human monitors, required in this study, from the system and replace them with autonomous monitors and interpreters. The result of this feasibility study will therefore be a set of tests using predefined components to illustrate that interpretation of centralized or distributed experience can produce a useful and sensible plan of action. This initial research will identify the ability to interpret and human behaviors making it immediately appealing to disabled people to use as a prototype interpretation system of their needs and wants.

Title:New Event Detection
Abstract:Intelligence organizations want to know when an unprecedented event or new information is reported. While there is good technology for searching, tracking, and filtering on known topics, current methods do poorly at detecting something new. The chief mechanism of search and topic tracking, spotting important words, is innapropriate-new stories are not ones with no important words. Because the degree of difference of new and old is different for different topics, uniform thresholds for overlap, as used in current filtering technologies, are also inapproriate. This project approaches the problem in three new ways. First, it applies Latent Semantic Analysis (LSA), a machine-learning technology that simulates human understanding of discourse. After automatic training on a large body of representative text, LSA accurately measures amount of meaning similarity between two passages using all the words in both. Texts with a few words in common are not judged similar if their meaning is different, but are, even if they use entirely different terminology, if their meaning is the same. Second, the system interacts with human users to adapt its criteria to their interests and the characteristics of the data. Third, it uses novel LSA-based storage and retrieval techniques to increase efficiency and capacity. The target innovative new event and new information technology will be of benefit to intelligence agencies and government and private organizations needing to keep abreast of news and developments in commerce, science, and world affairs.

Title:Modeling Topic Pragmatics for Improved First Story Detection
Abstract:We propose an innovative combination of machine learning techniques and pragmatics modeling in pursuit of high accuracy, domain- and language-independent First Story Detection. Our Topic-Oriented Pragmatics and Invariant Chaining (TOPIC) system will automatically construct topic category models that explicitly capture the pragmatics of how topic cohesion is maintained across the stories that constitute a news topic. These models will be used to generate predictions about the types of stories expected on diverse news channels, providing a hitherto untapped source of novelty discrimination. Central to our pragmatics-based approach is the idea that the invariant entities and events that constitute a topic are better determinants of topicality than full-text similarity measures. Our model-based techniques combine with statistical text-similarity algorithms to provide independent perspectives on story topicality. Committee-based methods arbitrate these multiple classification viewpoints. TOPIC also exploits redundancy in pragmatics expression across news channels and source languages. Phase I research and development of a proof-of-concept limited prototype will demonstrate the feasibility and utility of TOPIC's First Story Detection capability and will lay the groundwork for its Phase II implementation and eventual commercialization. Besides being an important tool for intelligence analysis, TOPIC would also prove useful in numerous commercial domains (e.g., competitive market analysis and epidemiology) where the identification and monitoring of topical news articles is a requirement. Another exciting application is in the creation of individually customized news reports.

Title:Biomolecular Optical Nanostructures
Abstract:Biology provides a vast number of examples of nanostructures produced at a level of precision that is superior to those that we can produce in the laboratory. The diversity of naturally occurring S-layers suggests that the nature of these self-assembled structures is genetically controlled and can therefore be manipulated through recombinant processes. In this Phase I research plan, Agave BioSystems proposes to combine S-layers, a self-organizing component of bacterial cell walls, with newly described luminescent nanoparticles to generate novel structures containing regular arrays of photoactivatable fluorescent materials. This approach can yield complex optical nanostructures much faster and much cheaper than by other nanofabrication techniques. Of particular interest is the use of these optical nanoarrays for high-density data storage. Data storage using this technology would not only yield significantly greater capacity, but would also increase access speeds, improve reliability and reduce manufacturing costs. Revolutionary new electronic and optical devices could be made possible with the ability to reliably create large arrays of nanoparticulate systems. Possible applications include optical data storage devices, deep UV and x-ray diffraction devices and optical components, and novel biomedical fluorescent detection devices. Once the technology is fully developed, these nanostructures could have a significant impact on the multi-billion dollar computer, optoelectronics, and communications markets.

Title:TRANSDUCTIONAL ELASTIC PROTEIN-BASED POLYMERS AS NANOSENSORS BY AFM/DFSBY AFM/DFS
Abstract:This Phase I SBIR to DARPA brings together five remarkable elements relevant to elastic protein-based polymers for the development of diverse nanosensors: i. the incomparable protein compositional control of biology, ii. a consilient mechanism of energy conversion utilizing inverse temperature transitions capable of eighteen classes of pair-wise energy conversions, iii. polymers that develop the highest known acoustic absorption on undergoing the transition, iv. polymers with perfectly reversible elasticity for efficient mechanics-based transduction, and v. adding dynamic force spectroscopy capacity to atomic force microscopy for monitor the free energy transduction. The technical objectives are: (1) To design, prepare and verify a specific elastic protein-based polymer composition for development as nanoscale chemo-mechanical and electro-mechanical transducers, (2) To assemble polymer chains into multi-stranded twisted nanofilaments capable of chemo-mechanical transduction using the COOH/COO- chemical couple and of electro-mechanical transduction using the NAD+/NADH redox couple. (3) To develop the capacity of Dynamic Force Spectroscopy to measure changes in the acoustic absorption of twisted bioelastic nanofilaments suspended between cantilever tip and substrate surface of an AFM apparatus, and (4) To detect free energy transduction at the nanoscale due to the chemical and electrochemical potential changes noted above in (2), that is, to develop these specific nanosensors. The anticipated benefits flow from the extreme versatility of the nanosensor design that employs elastic protein-based (bioelastic) polymers and their inverse temperature transitions capable of eighteen classes of pair-wise energy conversions involving the intensive variables of mechanical force, temperature, pressure, chemical potential, electrochemical potential and electromagnetic radiation. As a protein-based nanosensor, it promises the famed selectivity and efficiency of protein-based machines. When combined with atomic force microscopy (AFM) and dynamic force spectroscopy (DFS), there is potential for the ultimate in sensitivity, i.e., single molecule detection. Design of the device removes the repeated requirement to scan in the z-direction using a piezo with strain gauge, but rather allows for the more robust circumstance of a fixed z setting and detects changes in the acoustic absorption attending the transductional event. While the number of applications appears to be limitless with this design of nanosensor, we might note detection of nerve gases, explosives (DNT, TNT), assay of kinase activities for medical diagnostics, etc.

Title:Organic Semiconductor DiazoBioPolymers as Energy-Transducing Nano-Assemblies
Abstract:SOLUS Inc. proposes to develop novel organic biopolymer nano-assemblies based on diazotized melanoid building blocks. Peroxidated and nitroperoxidated non-metallated and metallated versions of these unique organic polymers, which demonstrate semiconductor-type energy transduction properties, will be synthesized. Additionally, novel bioenergetic polymer-silk hybrid nanoassembled materials will be prepared by recombinant fermentation techniques. Using proprietary methodology, polymer reactive derivatization sites will be coupled to julolidine molecular rotor moieties in order to achieve enhanced modulation of energy transduction. The effects of metallation with different rare earth species, and the effects of molecular rotor coupling, on energy transduction semiconductor behavior of the polymer nanoassemblies will be assessed utilizing dynamic fluorescence, ECL, and rf-excitation modalities. Particular focus will be devoted toward exploring the photovoltaic properties of these bio-organic polymer and polymer-silk hybrid nanoassemblies, as well as their Phase II and III development potential for integration as energetic nanodevices across a range of innovative nanoengineering product applications within the areas of biomedical instrumentation, implantable biomimetic materials and devices, photovoltaic solar cell films, and solid state biosensors. The commercially-exploitable opportunities for these polymer and polymer-silk hybrid nanoassembled bioenergetic device materials are formidable. Four major market segments for commercialization of this technology have been identified: 1) solid state surface imprints for diverse biosensing applications, 2) organic polymer photovoltaic materials for solar cell technology, 3) rf-activatable liquid phase energy transduction-driven biosensor designs for remote sensing applications in biodefense and geoplanetary science and agriculture, as well as 4) energetic materials and device technology for implantable bionics, other biomaterials, interventional biomedical devices and biomedical instrumentation. Particularly in the case of the biosensor and solar cell market domains, the commercial potential is extensive.

Abstract:Molecular Imprints, Inc. (MII) is a startup company in Austin, Texas, set up to develop and manufacture a unique line of nano-resolution lithography and associated semiconductor equipment based on a proprietary new technology developed at the University of Texas at Austin. MII has acquired exclusive rights to the intellectual property associated with Step and Flash Imprint Lithography (S-FIL) technology. S-FIL technology has the potential for being a low-cost, sub-50 nm, high-throughput process that has been carefully designed to substantially exploit the existing infrastructure in the semiconductor industry. MII would like to investigate the extension of S-FIL technology to the area of compound semiconductor substrates. These materials are known to be fragile, and have significant material compatibility issues at high temperatures. This proposed effort will explore the development of novel nanoimprint tools for processing compound semiconductor wafers without the use of high pressures and temperatures. The proposed research will lead to nano-lithography tools that can reliably and repeatably allow patterning of compound semiconductor devices with high process yields.

Title:Innovative, High-Throughput, Large-Area, Versatile Nanoimprint Tools
Abstract:Based on the previous extensive work on NIL in Prof. Chou's group and at Nanonex Corporation, the objective of the project is to further develop a promising innovative nanoimprint lithography (NIL) machine design. The design, using a new principle, offers not only excellent uniformity of nanostructures over large areas, high-throughput (<60 sec per wafer), and scalable to 12" diameter wafers, but also it eliminates the relative lateral shifts and rotation between the mask and the wafer during the imprint (crucial to the alignments) and it provides the versatility that one machine can perform different imprint methods: from deep 3-dimentionlal imprint in a thermal plastic material to imprint in a UV (or thermal) curable polymers. The key personnel of Nanonex include former Post-docs and graduate students of Prof. Chou's group, and are experts in NIL. Nanonex has the exclusive rights on the NIL principal patent as well as other intellectual properties related NIL (including those obtained from the University of Minnesota and Princeton University), therefore having a unique position in commercialization of NIL. The commercialization of such unique NIL machine will significantly advance NIL applications. The success of the proposed project will provide DoD a revolutionary manufacturing tool that can significantly impact many areas in the military and civilian hardware, such as high speed wireless and optical communication, displays, data storage, integrated circuits (ICs), pharmaceutics, biotech, chemical synthesis, to name just a few.

Title:Virtual Ultrasound Transducer Control for Telemedicine, An Application of Flexible MEMS Arrays
Abstract:Sensant Corp intends to investigate the use of microfabricated ultrasonic transducers to enhance paramedical triage. Sensant Corp believes that recent improvements in transducer technology now enable the realization of a flexible patch composed of a 2 dimensional matrix of ultrasonic elements. Such a patch, when combined with the appropriate processing hardware and algorithms, would allow remotely located specialists to arrive at diagnoses and recommended courses of action for injured soldiers on far forward echelons. The recent application of micro-electromechanical systems (MEMS) technology to ultrasonic devices has created an advanced ultrasonic sensor with significant advantages over conventional piezoelectric transducers. These new ultrasonic transducers are fabricated in the same manner as a silicon chip using a technique known as micromachining. In many cases, these devices can be monolithically integrated with conditioning electronics, and/or made to be flexible. Such flexible transducer patches would allow the remote specialist to virtually manipulate the transducer, and possibly even collect a volumetric data set. For this research, Sensant will perform a detailed feasibility study culminating in the design of a flexible ultrasonic transducer patch and corresponding beam-forming and signal processing algorithms. Tangible deliverables would include a detailed performance requirement specification for both the transducer array and the processing system and simulations demonstrating that such requirements indeed generate a useful diagnostic imaging capability. Sensant would also deliver process flows of viable fabrication schemes for both transducer and packaging. Sensant may also deliver first silicon of a simple 2-D transducer matrix, though this part of the effort would be financed with Sensant's own funds. Should the research prove successful, immediate opportunities for commercialization in civilian pramedical triage would materialize. Priceless value would be realized in the form of fewer combat fatalities and fewer civilian trauma fatalities. Furthermore, great cost savings would be achieved in both military and civilian healthcare expenditures because appropriate triage reduces the number of complications that require heroic medical efforts to overcome. If extremely successful, this effort would also improve conventional medical ultrasound even in non-triage applications.

Title:A study on the feasability of designing, fabricating, and operating a virtual ultrasound array
Abstract:This proposal presents a practical study of the issues and tradeoffs involved in making an ultrasound array which is capable of being operated from a remote location. The classic performance vs complexity tradeoffs are presented. The parameters which can be adjusted are listed, along with the performance variables which they affect. The number of elements and the form in which they are addressed is shown to affect the overall coverage and the flexibility that the physician has in selecting an active aperture and beam direction. After determination of the imaging applications which the array will be used in, a thorough analysis of these variables is proposed, from which the feasability will be determined and the specifications set for hardware development under a Phase II program. Remote operation of an ultrasound array is expected to have far reaching applications in both the civilian and defense sectors, including front line, triage, and trauma operations. Tie-in to a rapid diagnosis and treatment program is possible. Development of this system could also enable ultrasound specialists to perform examinations from remote sites, and in an interactive manner be able to gain the same clinical insight as if they were present at the patient location. Commercialization of direct and spinoff technology developed under this program is expected to be significant.

Title:Spin Dependent Tunneling Magnetic Field Sensors for Clutter-Limited Detection
Abstract:Highly sensitive, low power, rugged, and compact sensors are required for many military applications. Spin Dependent Tunneling (SDT) devices have been fabricated into magnetic field sensors that perform well, and have the lowest effective noise floor of any magnetoresistive sensor at high frequencies. Next generation devices, whose noise floor should approach 1 picoTesla / root Hz at 1 Hz, have the potential to meet all of the requirements for the application specified in this solicitation. Additional work is required beyond achieving basic sensitivity levels. In particular, algorithms and devices must be developed to permit several of these devices to function as a set of long-baseline gradiometers in a remote setting. This proposed Phase I SBIR effort will address these requirements. A matched field processing approach will be examined as a mode of operating in the field. Several techniques for magnetic field self-calibration and orientation will be studied. These include using the ambient earth's field and geomagnetic noise as calibration sources, and generating calibration fields using the magnetometers themselves. A low power SDT sensor will be made and tested. A successful Phase II project would add electric field measurements, power, and communications hardware to the basic SDT transducers. SDT magnetic field sensors fill a need for a wide range of commercial applications. High impedance, and high sensitivity, wide bandwidth, small size and low power give them significant advantages in the marketplace. Applications include vehicle detection, currency detection, defect detection using eddy currents, buried object classification, and geophysical analysis.

Title:Clutter-Limited Electric and Magnetic Field Sensor with Self Orientation and Calibration
Abstract:Over the last year QUASAR has designed and demonstrated prototype vector electric and magnetic field sensors that set new performance benchmarks, and already meet the sensitivity objectives, and most of the size and power requirements, of this solicitation. In addition, these sensors are solid state and very low cost. In Phase I a self-orientation sensor package will be constructed from COTS components and tested in close proximity to the E and B sensors to determine compatibility for integration. In addition, a series of experiments will be conducted with a compact QUASAR E-field sensor to compare calibration approaches based on the environmental noise and source fields. The result of Phase I will be a top level design for a multiaxis electric and magnetic field sensor package with self orientation and self calibration capability. In Phase II, three complete E and B sensor packages with hardware and algorithms for self orientation and calibration will be demonstrated in remote and urban environments, both as standalone sensors and in gradiometer mode over baselines of several hundred meters. The proposed system has the potential to provide the complete collaborative electromagnetic sensor solution called for in the solicitation without requiring advances in the underlying sensor technology, or in support hardware. Other government applications include direction finding, vehicle, personnel and machinery detection, lightning detection, and planetary exploration.

Abstract:The goal of the proposed work is to develop and demonstrate self-orienting and self-calibrating, low frequency field-deployable electromagnetic (EM) sensors. The focus will be on EM sensors which support long-baseline gradiometry and which have the following characteristics: small size, low power, broadband, high sensitivity, high dynamic range, and robust outdoor performance. Low frequency EM sensors are needed for military applications addressing target location, planning, and movement. More specifically, Quantum Magnetics will perform R&D work in the following two areas: 1) Development and demonstration of sensor nodes, and 2) development of supporting algorithms (self-orienting, self calibrating) that would enable the EM sensors to operate in robust outdoor environments. A highly sensitive low frequency EM sensor would find numerous applications in security operations and perimeter surveillance, detection and characterization of underground facilities, detection of military vehicles and and armed troops, monitoring of urban and highway traffic, and geophysical applications.

Title:Enhanced Turbojet Inlet Injection
Abstract:Accurate Automation Corporation (AAC) proposes to develop an analytical and experimental database that demonstrates the basic feasibility of inlet injection of oxidizer in turbojet engines for turbojet acceleration. This will enable operation of conventional turbojets to higher Mach numbers, to higher speeds, and to higher altitudes than they are current capable. This is a step in using the nation's inventory of these assets for new applications and, in two-stage-to-orbit systems using these engines, brings the U.S. closer to "airline-like" access to space. Accurate Automation Corporation will develop an enhanced inlet oxidizer injection system. We will use this to increase performance of small turbine engines as well as license the technology to major engine manufacturers. Accurate Automation is working with AMT to develop a product line of advanced turbine engines.

Title:Precompressor Cooling With Water and Oxidizer for Small Access to Space Vehicles
Abstract:The development of a pre-compressor mass injection system for extending the flight Mach number and altitude of conventional military afterburning turbofan engines is proposed. The injection of water and liquid oxidizer such as liquid oxygen can be used to enhance the performance of these engines so that they may power the reusable air-breathing first stage of a space access vehicle. The fluid injected into the inlet may serve three purposes. First, it can cool the air entering the compressor so that the engine may be operated to higher flight Mach number. Second, it can increase the net mass flow through the inlet so that the engine can generate more thrust. Third, it can provide additional oxidizer so that additional fuel can be added in the engine afterburner further augmenting the engine thrust. It is anticipated that the coolant injected upstream of the compressor may be vaporized before entering the compressor face. This minimizes the effect of the coolant injection system on the engine operation thereby simplifying the development effort. This system development includes the development of water/oxidizer supply system, the spray injection system, modification or extension of engine controls and potentially the modification of the afterburner and nozzle. An accelerator afterburning turbojet engine that is capable of flight to high Mach number and high altitude has significant commercial and military markets in space launch applications. This technology can also be applied to high-speed, long-range, rapid response missiles. Supersonic business jets also have the need to accelerate quickly to their cruise altitude and speed. This technology could enable the engines of these vehicles to be optimized for cruise, while still have the capability to climb and accelerate with the assistance of this technology. Water injection can be optimized to increase the output power of industrial gas turbines for electric power generation.

Title:A Trans-Atmospheric Turbojet Engine
Abstract:A novel turbojet based propulsion system is described that is capable of continuous operation from takeoff to orbital insertion. This engine concept utilizes a conventional turbojet as its core with a dual function inlet that can accommodate both atmospheric air and cryogenic liquid oxidizer. By varying the percentage of liquid oxidizer injected, the engine can operate either in turbojet mode, rocket mode or in a combination mode. At all times the delivered performance is equal to or better than an equivalent rocket. The system has the potential for high performance while maintaining the low lifecycle costs associated with conventional turbojet engines. The investigation includes determination of appropriate operating scenarios for the system through engine cycle analysis. Hardware interactions are evaluated to determine what modifications may be necessary to allow utilization of existing turbojets for component testing. Lab-scale testing is conducted to demonstrate concept operation as well as investigate injector performance. A plan is prepared to investigate full scale concept testing using a representative turbojet engine during Phase 2. Commercial applications for this propulsion technology exist not only in orbital space transportation systems, but high-speed point to point air transport systems as well. The long life and low lifecycle costs of the core turbojet engine make it well suited for high flight rate transportation systems requiring high thrust to weight, high speed engines with reasonable propellant economy. Potential applications include orbital transportation, high speed, long range trans-atmospheric package delivery aircraft, as well as trans-atmospheric military strike or reconnaissance aircraft.

Title:Mach 6+ Turbine Engine with Inlet Air Conditioning
Abstract:In support of the DARPA efforts focused on delivering higher thrust-to-weight ratios, reduced cost turbine engine technology as well as developing innovative and high Mach airbreathing engines, MSE Technology Applications, Inc., with the Air Force Research Laboratory, proposes to design, develop, and test a new high Mach engine concept, the SteamJet(TM), which is based on existing turbojets. This will provide the DoD with a low cost, low risk propulsion system possessing unique control and acceleration/deceleration features for small hydrocarbon-fueled flight vehicles such as missiles, interceptors, and launcher accelerators. SteamJet(TM) employs a simple, low cost modification to a conventional turbojet engine to reduce the high incoming air stagnation temperature at high Mach numbers and compensate for compressor performance deterioration. The main innovative feature is that SteamJet(TM)is the only airbreathing cycle that permits vehicle acceleration with a single type of engine (as distinct from, for example, the turboramjet) from sea-level static conditions up to Mach 6+. The SteamJet(TM) is a high thrust engine with very flexible thrust control, and it is fueled by commonly available fuels. SteamJet(TM) technology is environmentally clean and it is equally applicable to both military and commercial launchers as well as other high speed vehicles. Additionally, it will help to reach or exceed several IHPTET Phase III goals by the year 2003. The SteamJet(TM) concept has unique competitive advantages of higher performance than solid or liquid rockets, provides thrust from sea-level static conditions to Mach 6+, and has a higher thrust-to-weight ratio than a comparable ramjet. Being completely within industrial capability, this low cost modification of existing turbojets offers a variety of thrusters for DARPA, USAF (Pegasus-type launcher, air-launch missiles), U.S. Navy, and Ballistic Missile Defense Organization (BMDO) missile systems (e.g., for such applications as Patriot-type Defense Systems, Navy Area Defense, and the Theater High-Altitude Area Defense System), and experimental vehicles like NASA X43B.

Title:Inlet Injection of Oxidizer for Turbojet Acceleration
Abstract:Liquid oxidizer injection in the compressor section of turbojet may allow it to operate at high Mach numbers and altitudes. The evaporation of the oxidizer decreases the compressor discharge temperature and inter-stage cooling increases the airflow. These effects allow fuel flow to the combustion chamber and afterburner to be increased with resultant higher thrust. The oxidizer increases the concentration of oxygen available for reaction with fuel. This reduces flameouts during high altitude operation. The oxidizer mass flow contributes to the mass expulsion rate of the engine further increasing thrust. Such an engine may be used in the future on the first stage of space boosters. Spath Engineering proposes conducting analysis of oxidizer injection into a J-85 turbojet engine with afterburner. A NASA provided computer program would be used for engine cycle analysis. Modification and test of a government furnished engine is also proposed. The modifications to the engine will allow liquid oxidizer to be injected at the inlet and two compressor stages. The test data will validate the predictions of the analytical work. This analysis and test program is designed to stay within the funding limits of a phase I SBIR. A turbojet engine that has the ability to operate at high Mach numbers and high altitude has the potential to revolutionize space operations. A launch vehicle with an air-breathing first stage could cause space launch logistics to approach those of present day aircraft operations. The potential impact of such an engine is difficult to overstate. Spath Engineering has identified a dual use commercial application that is feasible within the funding and scope confines of an SBIR phase II program. Some models of Learjets are FAA certified to operate at FL 510 (51,000'). Early models of Learjets, including some certified to FL 510, use the General Electric CJ-610 (the civilian version of the J-85). Flight International of Newport News, Virginia is the world's largest operator of special mission Learjets. They have expressed an interest in a modified CJ-610 to allow special mission operations at very high altitudes. Flight International has several Learjets that have been modified to carry external stores. Some carry the stores under-wing and some at a fuselage belly station. Use of these aircraft may simplify the modifications to the airframe that would be required to carry liquid oxidizer.
