| Title: | A Small Image-aided Navigation And Path-planning System (SINAPS) for Small UAVs |
| Abstract: | Due to the limitations and power requirements of modern computational hardware and sensors, the central goals of smallness and high-level autonomy (usually associated with higher algorithmic complexity and computational cost) are directly at odds with each other. Current small UAVs often shed weight through the use of limited sensors and rudimentary algorithms, while very high-level autonomy usually comes packaged in a UAV that is by no means "small." Our proposed project is uniquely situated to tackle this "highly autonomous small UAV" challenge through the innovative combination of high-performance, compact hardware and efficient, advanced algorithms. The proposing team will combine a flight-proven, state-of-the-art miniature avionics system, flight-proven, real-time image processing techniques, and efficient, high-level autonomous guidance algorithms to develop a Small, Image-aided Navigation and Autonomous Path-planning System (SINAPS) for small UAVs. The Phase I result will be a complete flight-proven SINAPS with very high levels of autonomy contained in an extremely small, lightweight package. |

| Title: | Small UAV High-speed Obstacle and Collision Avoidance |
| Abstract: | A major roadblock towards full UAV deployment in urban and mountainous areas is their inability to negotiate obstacles and avoid collision with other aircraft while flying at or near cruise speed. There is an urgent need for UAV obstacle and collision detection and avoidance systems, which won't slow down the UAV significantly while analyzing the world and making decisions as to what is the safest route around obstacles and other aircraft. We propose to design and test a low weight, low power, and low cost UAV obstacle and collision detection and avoidance system. We will pursue an approach based on combining laser-, vision-, and acoustic-based systems. We also propose to develop route deconfliction and autonomous obstacle and collision avoidance methods. We will develop aircraft guidance, or planning, methodologies that take into account the amount and type of information provided by the sensors. To minimize data processing latency we propose to closely integrate the sensors and the corresponding pre-processing algorithms.By developing hardware and software in a modular way, we will be able to provide the maximum possible capabilities for each type of UAV at the right weight, power, and cost levels. |

| Title: | Environmental Sensor for Autonomous UAVS |
| Abstract: | Improved observations of the battlespace are of key and growing importance in today's combat environment. UAVs are making key contributions in this area, and sensor improvements are a key part of increasing UAV capabilities. However, all sensors are subject to degradation under detrimental environmental conditions. Adding a sensor system to UAVs that enables the in-situ identification and quantification of such conditions will aid in the most effective use of UAVs and their onboard sensors as well as enable more accurate evaluation of the sensor data being returned. Anasphere proposes to develop a highly miniaturized, low-power environmental sensor system - on the order of one to two cubic inches in volume, and with a power consumption on the order of 500 milliwatts - suitable for use on a broad variety of UAVs. Specific quantities to be measured include standard meteorological parameters, visibility, ambient light level, and precipitation rate and type. On-board processing will yield additional value-added parameters of significance. In Phase I, a proof-of-concept system will be designed, fabricated, and demonstrated on a UAV. The Phase I Option will involve definition of Phase II systems and UAV interfaces. Phase II would see iterative design improvements and tests culminating in a production-ready system. |

| Abstract: | An innovative multimodal environmental sensor (both LWIR and LIDAR) is proposed. It is accomplished by leveraging COTs technology, advanced optical design and fabrication technology, and commercializing university research. By coupling the two technologies and developing the appropriate algorithms the environmental conditions in front of a UAV can be mapped and communicated and/or used by an autonomous navigation system to control the UAV. The nature of the technology is such that its SWAP will be compatible with some of the smallest UAVs. Overall, this technology will provide capabilities that do not exist in any type of sensor system produced today. |

| Title: | Innovative Systems to Reduce One per Rev Vibrations in Helicopters |
| Abstract: | Significant maintenance activity is required to ensure acceptable 1/rev vibration levels from main and tail rotors. These flight and ground based maintenance activities translate into significant cost and downtime for the helicopter operator. Cost has been somewhat mitigated with the use of on-board systems with computerized diagnostic algorithms. The result is better ride comfort which translates into minimized pilot fatigue, and better helicopter and component life. The rotor tuning adjustments typically used are blade pitchlink length adjustment, trim tab angle adjustment, and rotor weight balance adjustment. These adjustments are manually implemented in a relatively inefficient way that is time consuming and sometimes prone to error. Ultimately an overall system is desired that would enable relation of the results of the computerized diagnostic algorithm to the automated rotor adjustment implementation system in an automated way such that the changes are made in a quick, efficient, accurate, repeatable, and error free manner. Mid‚ proposes to develop two innovative, robust solutions to adjusting the pitchlink length and rotor mass balance. Mid‚ has recently developed an active trim tab and successfully tested it on a whirl stand. These systems will be automated and would ultimately be adjusted in flight. |

| Title: | Robust Hybrid Feedforward-Feedback Control and Dynamic Rotorcraft Simulation for Active Vibration Control |
| Abstract: | In Phase I program Invercon will team with Bell Helicopter and PSU to further develop a package of simulation models and analysis tools recently created at Bell for AVC system design and evaluation. The analytical models have been developed in Simulink to accurately replicate various rotorcrafts vibration environment in steady flight and in transient maneuvers. The AVC control approach is introduced into the rotorcraft models via airframe and AVC actuator transfer matrices. Ultimately, the effectiveness of the given control approach can be observed through a time domain airframe response. Invercon and PSU will introduce hybrid feedforward-feedback control approaches into the model which incorporate both a modern control approach, such as the Linear Quadradtic Guassian (LQG) based on identified state space models, while also preserving traditional frequency-based helicopter control approaches, such as adaptive self-tuning regulators for multicyclic control. The control approach parameters will then be optimized so that broadband vibration suppression is maximized while control effort is minimized during both steady state and transient flight conditions. In Phase II, Invercon and PSU will then integrate the control approach into RCAS (Rotorcraft Comprehensive Analysis System), a nonproprietary government analysis tool that is a full-fidelity, comprehensive rotorcraft model. |

| Title: | Full Band Anticipatory Control Algorithms to Suppress Aggressive Maneuver Vibrations |
| Abstract: | Recent high usage of helicopters in Iraq and Afghan theatres underscores a need for rotorcraft safety and reliability improvements. Rotor induced vibrations cause significant airframe fatigue and electronic component failure. In current generation rotorcraft, vibration attenuation is achieved through either airframe mounted tuned-absorbers or active vibration control (AVC) systems. Typical AVC system uses a number of fixed-system, narrow band force generators to reduce the acceleration measured at multiple locations in aircraft fuselage. Although current AVC systems are effective at reducing vibration in steady-state flight, advanced control algorithms are needed to achieve similar results for dynamic maneuvers. To address deficiencies of current AVC algorithms Materials Technologies Corp. has formed an exceptionally talented team with experience in rotorcraft modeling, modern control algorithm development, and AVC system development. Proposed AVC algorithm development effort balances performance, computational, tractability, and certification complexity, utilizing state-of-the-art control technologies that address known deficiencies in production control algorithms. Phase I will demonstrate the most promising control algorithms in a high fidelity fuselage model developed in coordination with Sikorsky Aircraft. Control algorithms will be evaluated in hardware-in-the-loop testing on Sikorsky AVC test rig in Phase II to identify the best approach for dramatic vibration reductions in maneuvering flight that has the potential to significantly improve component lives and also flight safety by reducing pilot workload and environmental stressors. |

| Title: | Innovative Rotor Blade Anti-Icing/De-Icing Technologies |
| Abstract: | FBS, Inc. and the Penn State Rotorcraft Center propose the development of a novel ultrasonic guided wave phased array focusing technology for large area anti-icing and/or de-icing of rotor blade structures from a single sensing position. The concept is unique in that it utilizes a phased array actuation approach for ice prevention/removal. The Penn State Rotorcraft Center has recently shown the ability to use ultrasonic guided waves to de-ice aluminum, steel, and composite plate structures. Penn State's single actuator approach is only capable of localized de-icing which makes field implementation impractical because hundreds of actuators would be needed to de-ice an entire rotor blade. The phased array approach proposed here will allow large area de-icing by using an array of actuators and phasing them to constructively focus energy to a particular point on the surface of the structure (anti-icing) or the structure/ice interface (de-icing) while using high actuation frequencies that will not harm the structure. The focal point could then be scanned, using software, to focus energy to all points on the rotor blade to remove ice or prevent ice formation over a large area from a single actuating position. |

| Abstract: | To address the Army's need for innovative non-electrothermal rotor blade de-icing systems, Physical Optics Corporation (POC) proposes to develop a new Micro and Nano Structured Anti-Icing Coating (MANSAC) technology. This proposed technology is inspired by the surface structure of a lotus leaf in nature, which has superhydrophobic and self cleaning behavior that repels ice, water, and dust from its surface, without any electric power. The innovation in design and integration of a micro/nanostructure on the surface will enable the MANSAC to block ice formation on rotor surfaces. In Phase I POC will demonstrate the feasibility of MANSAC by coating the MANSAC onto the surface of the same materials as those similar to a rotor blade, and testing for the anti- and de-icing effect. In Phase II POC plans to identify fabrication processes and develop a prototype for demonstration in a realistic enviroment. |

| Title: | Smart Autonomous Miniaturized Contamination Condition Sensor with Embedded Prognostics |
| Abstract: | The U.S. Army Aviation Engineering Directorate, Propulsion Drive Systems Branch, has identified the need to replace the antiquated, differential mechanical pressure switch/indicator currently being used in hydraulic system filter applications on all Army helicopters, in favor of newer technology, MEMS based, piezoresistive, solid-state differential pressure transducer with temperature sensing combination for the added benefit of performing self diagnostics and prognostics capabilities to increase aircraft maintainability. The current mechanical design dates back 40 years, does not have temperature sensing capabilities, is incapable of processing information, or from being used for diagnostics and prognostics purposes for condition based maintenance, and it's inherent configuration makes it unreliable and problematic for users in the field, resulting in numerous false readings and premature component removals. In support of this effort, based on discussions with the U.S. Army's Aviation Engineering Directorate, Benz Airborne is proposing to develop a multi-platform concept for a diagnostic and prognostic measurement system (DPMS) that, if successful, could be used on all Army helicopters. The Propulsions Drive Systems Branch envisions this pressure transducer with temperature sensor capability, to be a drop in, stand alone replacement for the current mechanical switch. In addition, the pressure sensor shall have provisions for recording data through either a remotely located black box, or electronics incorporated into the head of the transducer, for performing diagnostics and prognostics capabilities. The DPMS will be completely autonomous with no electrical connectors to the vehicle. The DPMS will provide both visual presentation of hydraulic system health (e.g. lights) and recording of the pressure/temperature history. Recorded data shall be retrieved by maintenance personnel using either wireless or wired data link as desired. It is important to note that this pressure sensing device is to be used as a maintenance tool only, and that, it is not intended for pilot usage. |

| Abstract: | LURACO Technologies, Inc. proposes to develop a low-cost, accurate, and smart Multi-tasked Sensor (MultiSENS) that can be used to sense both the filter health as well as the fluid conditions. MultiSENS will directly replace the current Delta P indicator that is being used on current legacy aircrafts without interfering with the current wiring harnesses or system modification. MultiSENS can measure the differential pressure across the filter and determine the filter condition and predict the schedule for filter replacement. The basic function of MultiSENS is to automatically analyze and report the filter and oil condition. The proposed MultiSENS will be a complete, stand-alone sensing device that uses a MEMS multi-sensor chip to measure the pressure, dielectric constant, and temperature of fluid. MultiSENS will monitor the fluid and filter continuously or at scheduled intervals. The data captured by MultiSENS will be available for download via its data port, which implements a military-compatible communication protocol. |

| Abstract: | Applied Ultrasonics, Inc. has developed a unique patented commercialized, device that has proven successful in treatment of metals in the automotive and transportation industry. The goal of this SBIR effort is to demonstrate the feasibility of using this technology to improve the repair process of aviation components. The process known as Ultrasonic Impact Technology (UIT) can be compared to shot peening; however with three distinct advantages: 1) It uses a man portable device that can be used in forward deployed locations-eliminating the need to send parts to a specialized repair facility. 2) UIT can be used on aviation components that cannot be repaired with shot peening due to their size or shape. 3) The results of treatment with UIT are significantly greater than shot peening--greater fatigue life enhancement, corrosion prevention, and surface hardness. The goal of this Phase I effort is to demonstrate the feasibility of incorporating UIT in the Army's Aviation repair processes. Phase II will provide demonstration and airworthiness qualification on specific components. Commercialization of this technology will significantly reduce aviation operation and maintenance costs. |

| Title: | Field Repair of Localized Damage on Dynamic Rotorcraft Components. |
| Abstract: | U.S. Army helicopter fatigue sensitive dynamic components are required to maintain structural integrity throughout their operational life cycle. Typical metal alloy fatigue sensitive dynamic components require the presence of surface compressive residual stresses to inhibit the initiation and propagation of fatigue cracks. However, some of these components are susceptible to localized mechanical and corrosion surface damage that must be removed by blending. The surface blending process results in the requirement to reintroduce compressive residual stresses, normally by shot peening. The shot peening operation is currently performed at military depots and commercial facilities using non-portable peening equipment. Army Aviation has the potential for increasing reliability, availability, and maintainability (RAM), while reducing Operation & Support (O&S) cost by deploying a portable capability to reliably restore the structural integrity of fatigue sensitive dynamic components that have experienced usage related surface defects. Avion (Prime) and Sonats (Sub) have teamed to demonstrate the feasibility of developing a portable, field-deployable ultrasonically activated shot peening capability that reliably reintroduces compressive residual stresses in Army helicopter fatigue sensitive dynamic components that have had localized surface damage blended out. |

| Abstract: | Ceramic matrix composites (CMCs) such as silicon carbide/silicon carbide (SiC/SiC) extends the temperature capabilities of turboshaft engines thru higher temperature capabilities and reduced weight which provides improved horsepower-to-weight ratios. However, even uncooled ceramics can extend the capabilities of the engine to a certain plateau. If effective cooling channels could be incorporated into CMC (SiC/SiC) blades and nozzles even further increases in temperature capabilities at reduced weight and subsequent improved horsepower-to-weight ratios are achievable. A unique in-situ fabrication processing approach can produce cooling channels in controlled architectures within a SiC/SiC composite cross section. The processing will be developed and validated with establishing the mechanical properties and cooling effectiveness of SiC/SiC specimens containing multiple cooling channels which will be coordinated with engine OEMs. |

| Title: | Dynamic Blade Shapes for Improved Helicopter Rotor Aeromechanics |
| Abstract: | With the increasing demand for higher performance rotorcraft that will carry heavier payloads, travel longer distances, and hover at higher altitudes in warmer climates, more advanced and novel rotor designs have become necessary. The fixed configuration blade design has reached its optimum performance improvements. However, there is the potential to use a dynamic blade shape approach to significantly increase rotorcraft performance. Using the comprehensive tools to accurately model the new actuation systems and to analyze the new design in a more realistic manner has the potential to enable the creation of the next generation of rotors in a cost effective manner. With advancements in Computational Structural Dynamics (CSD) in structural loads prediction, the accurate airloads predictions by Computational Fluid Dynamics (CFD) programs, and the successful CSD/CFD coupling in both steady and maneuvering flights, the achievement of the above goal is within reach. ART proposes to use Rotorcraft Comprehensive Analysis System (RCAS) to model and analyze promising dynamic blade shape candidates and to create a database relating the performance parameter to the different morphing approaches over the entire flight envelope. Where necessary, enhancements will be made to produce the most accurate results. |

| Abstract: | HyPerComp Inc. is teaming with NextGen Aeronautics and the Rotorcraft Center at the University of Maryland to explore the use of dynamic blade shapes (morphing) for improved rotor performance. Team members complement HyPerComp's core expertise in modeling and simulation of the rotors, NextGen's vast experience in actuator design and fabrication, and consultation from University of Maryland on dynamic blade shapes and smart materials. We propose a high-fidelity CFD-based investigation of five different dynamic blade shape concepts for rotor performance improvement: (1) camber variation; (2) trailing edge deflection; (3) leading edge droop; (4) blade twist distribution; and (5) tip geometry (sweep, anhedral, and planform taper). The Phase-I study would be performed for the Black Hawk UH-60A rotor. Hovering, steady-level high-speed forward, and high-thrust forward flights will be studied. Loosely coupled CFD-CSD (aero-elastic) simulations of the isolated rotor (no fuselage) will be performed to compute trimmed solutions and rotor performance. Phase-I study would conclude with the documentation of the effect of the different dynamic blade shapes on rotor performance and the down-selection of the most effective ones. For those concepts, a preliminary study of the physical realizability in terms of actuation mechanism concepts, power, stroke, and frequency will be performed. |

| Abstract: | There are currently three different approaches under consideration for construction of multi-layer hemispherical multi-mode domes: (1) The bonded shell method - in which an inner and an outer dome shell are fabricated out of either ALON or Spinel, and bonded together, using a transparent adhesive, with a metallic grid at the interface, (2) The alternate dielectric method- in which an outer shell is fabricated out of either ALON or spinel, a grid is applied to its inner surface, and then an alternate dielectric (i.e., glass) material is directly bonded to the outer shell to create the desired structure, and (3) The Co-fired ceramic method- in which the metal grid is applied to green ceramics, and fired in such a way as to create the multi-layer structure within the as fired blank. The Phase I effort will combine a trade study of the preferred assembly method with a study of deterministic finishing techniques to determine the optimized manufacturing path toward producing a 7-in hemispherical dome with ¬ wave transmitted wavefront uniformity over any 4-in aperture. The Phase II effort will then consist of optimizing the selected method with a feasibility demonstration for producing up to 250 domes per month. |

| Abstract: | In previous work supported by the DoD SBIR program TA&T demonstrated an effective manufacturing route for spinel dome blanks. As discussed in the previous section, however, creating an effective process for the surface conditioning of the dome is essential to manufacturing them on a large scale. This Phase I will focus on an analysis of the manufacturing steps for a multi-layer dome to identify those steps which have the greatest contribution on the transmitted wavefront error of the finished dome. The feasibility study will propose techniques or processes which minimize the introduction of errors into the wavefront and evaluate deterministic polishing as a means correct the dome transmitted wavefront to meet the specification. To produce the feasibility study an investigation into current practice will highlight where wavefront error is being introduced and in the second portion of the study deterministic polishing, focusing on magnetorehological methods, will be investigated as a method for removing wavefront error. |

| Abstract: | Thermal batteries are mission critical components which provide power to military weapon systems for electronics, fusing, sensing and actuation. Today's thermal battery packaging and performance requirements are being pushed to the limits. System designers are demanding higher power levels over longer operating times (hence, higher usable energy output) in smaller, lighter packages. To meet this demand, we propose to demonstrate significant improvements in energy density, power density and operational lifetime using a new cathode material. The particle size range of the new material will cover micrometer to nanometer particle range. Material composition and processing will be optimized and performance improvement will be demonstrated in Phase I by means of single cell testing. In Phase II, ENSER will demonstrate the performance of the new cathode material in a selected PAC-3 battery. |

| Abstract: | The U.S. Army is seeking a technical innovation to thermal batteries with significant improvements on specific energy and operation life for weapon systems. One-time-thermal activation batteries have advantages compared with other types of reserved batteries in terms of long reserve-time, high reliability, maintenance free, high specific power, wide application temperatures, and good mechanical properties. The low voltage cathode and thermal life limit improvement on energy density and operational time of thermal batteries. US Nanocorp, Inc (USN) proposes a new high voltage nanostructured composite metal oxide and a new compatible electrolyte with a low melting point to address Army's request on performance improvements of the current state-of-the-art thermal batteries. Coupled with LiSi/LiAl anode, the new nanostructured composite metal oxide cathode will operate at 3V and have higher specific capacity compared with the current FeS2 cathode working at 1.7V. The application of the new cathode will increase the energy density 100%. The new electrolyte with a melting point <250oC and good chemical compatibility with high voltage cathode, will increase the active working time of the thermal batteries by increasing their thermal life (10X). The increment on active working life will also increase the energy density and reduce the battery's surface temperature. |

| Title: | Manufacturing Issues for Multimode Seeker Domes |
| Abstract: | There are currently three different approaches under consideration for construction of multi-layer hemispherical multi-mode domes: (1) The bonded shell method - in which an inner and an outer dome shell are fabricated out of either ALON or Spinel, and subsequently bonded together, using a transparent adhesive, with a metallic grid at the interface to create the desired structure.; (2) The alternate dielectric method- in which an outer shell is fabricated out of either ALON or spinel, a grid is applied to its inner surface, and then an alternate dielectric material is directly bonded to it to create the desired structure; and (3) The Co-fired ceramic method- in which the metal grid is applied to green ceramics, and then fired to create the multi-layer structure within the as fired blank. This Phase I will analyze the processes used in each of these approaches, and select the method most likely to produce a cost effective multi-layer dome in quantities up to 250/month. At the conclusion, any remaining process steps not mature will have a cost/risk reduction analysis presented. The Phase II effort would then consist of optimizing the selected method and demonstrating the feasibility of producing these domes in large quantities. |

| Title: | Manufacturing Issues for Multimode Seeker Domes |
| Abstract: | TA&T has demonstrated the capability to produce 7" diameter, hemispherical domes of transparent spinel by cold isostatic pressing (CIP) of spinel powder, followed by sintering without application of pressure, and finally followed by hot isostatic pressing (HIP). TA&T has exercised its dome manufacturing process sufficiently to have solved many process problems. At the same time, TA&T has gained a qualitative understanding of where the greatest costs are incurred and where the greatest risks remain. The proposed program will study the manufacturing process in greater detail in order to confirm current cost/risk reduction priorities and to quantify anticipated cost savings. A plan will be developed for scaleup to full manufacturing mode and to clarify opportunities for process improvement and substantial cost reductions. Value Stream Mapping and Theory of Constraints analyses will be used to identify/confirm the process steps that must be improved, by way of cost reduction or increased throughput. A revised manufacturing process that incorporates the needed improvements will be developed. Risk assessments will be performed for the revised process to assure that product and process objectives will be met. |

| Title: | Applying Technologies for Managing the Parallel Test Problem |
| Abstract: | The Army, as well as the DoD and Industry are not facilitated with software that provides the ability to perform Coherent Parallel Test utilizing high input/output (I/O) density test instruments and systems. Current test systems have been designed to perform sequential test which drive throughput limitations and affect the time spent testing and repairing Units Under Test (UUTs). Instrumentation hardware advancements are providing the ability to perform multiple (I/O) stimulus and measurement (with extreme increases in I/O density), as well as, increased parametric capability. There is currently no suitable software available to fully exploit the ability of this high density phenomenon to perform asynchronous, synchronous, concurrent and/or parallel testing. This innovative research program will focus on determining and developing the best available technologies necessary to allow the Army and Industry to enable higher throughput rates (faster tests), true parallel testing(in many cases true functional testing), advanced programming & visualization and improved diagnostics. |

| Title: | Learning and Mining using Bagged Augmented Decision Trees (LAMBAST) |
| Abstract: | Standoff weapons like seeker missiles enable strikes at targets of opportunity in limited-access areas while minimizing risk to warfighters. However, seekers cannot be deployed quickly enough for these short-notice missions because of two limitations of their onboard ATR systems: 1) ATRs cannot learn from novel, mission-specific data after initial training is complete; and 2) ATRs cannot identify pertinent, non-redundant information from large training databases. These limitations make it impossible to train a seeker's ATR in a feasible timeframe for short-notice missions. To remedy these problems and make short-notice seeker missions a reality, we propose LAMBAST, or Learning and Mining using Bagged Augmented Decision Trees. LAMBAST examines large databases and extracts sparse, representative subsets of target and clutter samples of interest. For data mining, LAMBAST uses a variant of decision trees, called random decision trees (RDTs). RDTs are immune to overfitting and can incorporate novel, mission-specific data after initial training via perpetual learning. We augment these trees with a distribution modeling component that eliminates redundant information, ignores misrepresentative class distributions in the database, and stops training when decision boundaries are sufficiently sampled. These augmented random decision trees enable fast construction of reliable, mission-specific ATR and make short-notice seeker missions possible. |

| Title: | Measure of Realness for Target Image Scoring (MORTIS) |
| Abstract: | One obstacle to the increased use of smart weapons and unmanned air vehicles is a lack of appropriate data to train current or contemplated onboard automatic target recognition (ATR) systems. Generating synthetic data is an appealingly simple solution, but this requires a simulator that can generate data (image/non-image) of sufficient fidelity to ensure correct ATR training. Unfortunately, synthetic and real data can vary widely, and there is no data validation mechanism that determines when synthetic data is sufficiently "real" to serve as training data for an ATR that will classify real data. Measure of Realness for Target Image Scoring, or MORTIS, is an automated data validation system that identifies data that can be used for ATR training by scoring data "realness". MORTIS uses a predictive approach to data classification, using many features and stepwise discriminant analysis. MORTIS attempts to learn to distinguish between real and synthetic data during a training phase and subsequently predicts if new data are real. When MORTIS identifies real data correctly, the synthetic data looks different than the real data, but when MORTIS fails to distinguish between the two types of data, the synthetic data is sufficiently real for ATR training. |

| Title: | Techniques for Comparison of Actual Target Signatures to Rendered or Synthetically Generated Models |
| Abstract: | In the development of modern sensor systems it is necessary to supplement actual performance testing with both digital and hardware-in-the-loop simulations to speed development and offset field test costs. The evaluation of signal/image processing algorithms along with sensor performance is often the primary goal of these simulations. The value of these simulations is only realized when the fidelity of the synthetic target and clutter models used is sufficient to provide an acceptable assessment of performance. As sensors attain higher resolutions and weapon systems become more advanced the requirements on synthetic target and background models become more difficult to meet. Some statistical methods, which have been used in the past to assess the fidelity of synthetic models compared to actual field measurements, have not provided the necessary understanding of the quality of the synthetic models. The objective of this research is to improve synthetic model verification capabilities by developing techniques to quantitatively compare synthetic models with data collected during field tests. |

| Abstract: | LIT proposes developing a HERO-Safe communication protocol to allow the use of RF transceivers to meet the requirements of a Virtual Wiring Harness for Hazardous Environments. LIT is teaming with Texas Instruments (TI) and will utilize TI's Chipcon family of RF components to achieve the low power and long battery life required to make the Virtual Sensor Wiring Harness a reality. LIT's teaming relationship with TI provides the Government Customer improved access to TI's low power processor and RF technology. The LIT HERO-Safe Protocol will address network registration and registration delay, node synchronization, data transfer, low duty cycle operation, and hierarchical networks in which the superior network that may not be static. In Phase I LIT will develop the HERO safe RF Protocol with the understanding that the sensor network, composed of sensor nodes and Data-Logging control node, is static. Size, mass, and power are especially important in this embedded sensor system. The long range goal of a one cubic inch system with a ten year battery life is realistic. LIT's team member, Texas Instruments, possesses state of the art low-power processor and RF technology which makes the ten-year battery life a realizable goal. |

| Abstract: | In Phase I we will develop a lab-scale prototype system of digital/analogue 3-d static as well as dynamic single droplet holography. We will also develop algorithms to visualize and determine the particle size, shape, and velocity of a droplet in a lab setup/gun tunnel. We will demonstrate the methodology for extending from single drop to multiple drops in a cloud. By building on the experimental knowledge gathered in Phase I, we will extend the work to Phase II where we will have many droplets in a cloud with a mixture of water, ice, dust and sand particles. In Phase II we will develop a full scale device with off-the-shelf hardware to record 3-D holograms of single droplet shape, velocity and density. Also in this phase we will study particle size distributions and velocities. We will build a friendly user interface for calculating the various parameters that our theoretical study can determine such as average and standard deviation of the particle sizes, their average and dynamic velocities, and the corresponding distribution laws. In Phase III we will help in integrating our device with the aviation and missile test setups to measure particle characteristics. |

The proposed DHDCAS is based on dynamic holography with an enhanced photorefractive semiconductor material. The innovation in DHDCAS will enable the system to record holograms at a very high speed, which will allow recording and visualization of dynamic events and provide 3D information of water droplet demise. In Phase I POC will demonstrate the feasibility of DHDCAS by designing, analyzing, and fabricating a breadboard setup. In Phase II POC plans to develop a prototype to test its capabilities of high-speed recording, displaying water droplet demise due to vehicle-induced shocks, and measuring particle velocity and size distributions, shape, and mass as a function of time in 3D volume domains. |

| Title: | Automated Risk Assessment Tool to Optimize Missile System Affordability Management |
| Abstract: | In recent years, there has been a strong emphasis on addressing affordability during Army Science and Technology (S&T) efforts to reduce the life-cycle cost of missile systems. Studies have shown that considering technology and manufacturing maturity, in conjunction with affordability principles during development yields significant benefits in several important area, including lower total costs and improved quality. Although progress has been made to incorporate this concept early in technology development, there are no automated, decision-aide tools available to help Army managers and analysts understand the impacts of the risks and cost trades associated with technology investments. This Phase I research will examine the feasibility of the type of affordability analysis toolset. This capability will enable developers and planners to estimate the cost impact of designs quickly and with credibility, enabling life-cycle cost, and the maturity of technology and manufacturing to be used as key elements in "best-value" design trades. The integration of technology maturity and manufacturability considerations into the cost-estimation methodology will provide a capability acknowledged by the Defense Science Board as an important issue in systems acquisition. The Phase II program will fully develop a prototype computer-analysis tool, and validate its functionality with Army-specific missile systems. |

The proposed asset-mounted sensor will be capable of long term autonomous collection and analysis of vibration data from an integral multi-axis accelerometer. The author's significant vibration experience will be used to modify existing analysis techniques for the sensor's real time processing. All saved data and processing results will be transferable to an external system via an onboard USB port for further post processing. The authors will adapt existing Impact-developed embedded data acquisition systems for use in this program or utilize COTS components whenever possible. Impact is well positioned to leverage their experience and knowledge of vibration measurement systems in order to develop a commercializable product for application on a variety of systems, including unmanned aerial and ground vehicles. The proposed design will be demonstrated via prototype tests during Phase I. |

| Title: | High Strength, High Modulus Nano-Composite Missile Structures (MSC P7017) |
| Abstract: | The Army has expressed a need for developing lighter weight alternatives to replace the aluminum structural components currently used in high performance missile systems. While advances have been made in formulating chopped carbon fiber composites with improved mechanical strength and stiffness at much lower densities than aluminum, current state-of-the-art chopped fiber reinforced composites do not provide the desired strength and/or stiffness properties. Newer material formulations and processing approaches using carbon nanotube reinforced composites and tailored, oriented fiber reinforcements are proposed to offer the potential for improving mechanical properties. The proposed innovation involves the formulation and characterization of improved CNT-reinforced molding compounds, and high stiffness/high strength structural components, that are produced using tailored reinforcement forms and material constructions rather. This processing approach allows the use of higher concentrations of CNT and chopped fiber reinforcements for improved properties at "processable" viscosities. Structural components fabricated using customized oriented molding compounds will be developed and evaluated to achieve increased properties and improved processing characteristics over more conventional chopped fiber moldng compounds. An Integrated Product Team has been assembled to ensure successful transition of the material and processing technology to viable military and commercial products. |

| Title: | High Strength, High Modulus Nano-Composite Missile Structures |
| Abstract: | Over the past ten years, it has become increasingly clear that carbon fiber composites can replace more common engineering materials such as aluminum in weight critical, structural components, such as those found in missile systems. Nanoscale materials, such as carbon nanotubes, can impart superior mechanical properties to these composites, and thereby allow composites to replace more components. However, they require careful optimization before the properties inherent in nanomaterials are manifested in the bulk composites. In the proposed Phase-I investigation, NanoLab will apply our expertise in nanotube catalysis, growth, and chemical functionalization to chopped carbon fibers and the preparation of composites with them. NanoLab will work in this Phase I effort to identify the optimal length, site density, and functionalization scheme to optimize the properties of chopped fiber based, epoxy filled carbon composites, with the goal of matching the properties of aluminum alloy 7075 at a lower density. |

| Abstract: | There is a need for small, low cost, wireless sensor platforms for in situ monitoring of missiles and other assets. These highly integrated sensor platforms should be small and energy efficient enough to operate on a single battery for a period of fifteen years. The objective of this work is to develop a 1 cubic inch wireless sensor platform with integrated temperature, humidity, and 3-axis shock sensors, provisions for connection of remote sensors, HERO compliance and with a wireless interface that meets the existing requirements of TR-AMR-SG-06-34. In addition to the sensor platforms, we will develop a hardware and software interface required to allow the platforms to communicate with an existing handheld interrogator. The proposed concept pushes the state of the art but leverages Sporian's previous work on energy efficient wireless sensor network hardware and software. The effort maximizes use of existing components and technology to reduce overall development risk. Work tasks include the evaluation of several novel concepts to reduce platform size and minimize energy consumption, and will result in a preliminary system design and proof-of-principle prototypes. The work will be performed through a partnership between Sporian Microsystems, Titanium Mirror, Inc. and Lockheed Martin Maritime Systems and Sensors division. |

| Abstract: | CFD Research Corporation (CFDRC) in conjunction with the New Jersey Institute of Technology (NJIT) propose to develop a fuel gel based on the Army's most current tertiary amine MMH replacement fuel. We will develop a novel technology for the production of nanoparticles by employing the supercritical antisolvent (SAS) process. With the use of our proprietary software technology that allows us to predict the physical properties of gels in silico, we will be able to predict the properties of the gels reducing the number of gel batches necessary to obtain the desired physical properties. Current churn-mixer gelling processes will be adapted to accommodate gelling a mixture of tertiary amines with nano-sized particles to obtain a consistent and reproducible gel mixing process. Complete preliminary rheological measurements to demonstrate that the fuel gel candidates will pass the standard Army developed leak test will also be conducted. The volumetric performance of the candidates will be determined by using the Cantera thermochemical code. These formulations will have a higher volumetric performance and a lower gellant concentration than the corresponding fumed silica gel currently the baseline gel. In Phase I we will establish the feasibility of our nano-particle fuel gel technology and in Phase II we will scale-up the preparation process, conduct thorough rheological and properties characterization, and position the technology for effective Phase III transition to the Army customer. |

| Title: | Secure, Lightweight, Tamper Proof, Cable Technology |
| Abstract: | LIT proposes a modular Fiber Optic Universal Cable Adapter. Fiber Optic (FO) technology provides high-speed communication bandwidth (into gigabits per second) with advantages in weight and security. FO is intrinsically secure over the Electro-Magnetic spectrum. FO is suitable for cabling applications over short distances (1 meter) to long distances (10 kilometers). FO cable has weight advantages because fiber is inherently lighter than wire and because shielding and differential pairs are not required for secure high-speed data transmission. Because of these bandwidth, EMI, distance, and security features, no wire based serial data system can compare to Fiber Optic. The UCA must be configurable to allow for any combination of signals or signal types. The U. S. Military uses standard communication interfaces, but also depends heavily on custom interfaces. The UCA needs a method of interfacing numerous signal types (such as analog, digital, serial communications, and power) without requiring a complete system redesign each time a different signal type is encountered. The modular approach provides the apparatus to conveniently incorporate any signal or interface into the UCA. The LIT solution incorporates Built-In-Test, health monitoring, self-healing, redundant connectivity, Forward Error Correction, Anti-Tamper and encryption technology for system and data protection. |

| Abstract: | This effort proposed is tailored for a hypersonic class missile "UAV" to evaluate the opportunity to optimize fragment dispersion as it relates to the engagement geometry and timing uncertainty for threat classes that are intercepted within the atmosphere. Store separation, or in the proposed context, smart dispense of a lethality enhancement device, is extremely difficult to evaluate via analytical means without validating the predicted solutions with ground test. Essentially, the problem is characterized by the canister separation from the UAV, canister blast dynamics, and particle dispersion in a hypersonic flow. Pattern shaping to enhance lethality based on engagement geometry and intercept timing uncertainly is accomplished by independent ignition timing for each of the dispensed canisters. |

| Abstract: | Boron Nanotubes (BNTs) have been predicted to have characteristics that are distinctively different than those of carbon nanotubes (CNTs), particularly with respect to physical and chemical properties. However, the development of BNTs is still in its infancy due to the lack of research performed in synthesizing BNTs. We propose to demonstrate the feasibility of synthesizing BNTs using a novel two-step process. The key innovation proposed here is to utilize a precursor structure of boron that will transform readily to BNTs. Further, an aspect of the proposed technology will allow long-term storage of BNTs by preventing any oxidation due to exposure to ambient atmosphere. In Phase I, phase pure and high purity BNTs will be synthesized and characterized for structural and chemical purity, which will result in the development of a protocol for synthesizing BNTs under optimized conditions. Additionally, the dispersabilty of BNTs, which is one of the critical parameters that determines the commercialization potential of BNTs, will be studied. Commercialization and scale-up plans will be developed during Phase I, and implemented in Phase II. A pilot scale system for the synthesis of BNTs will be delivered to the ARMY at the end of Phase II. |

The significance of this proposal is that for the first time, boron nanotubes (BNTs) will be synthesized in high volume for use practical materials. Academic research data and analysis signifies that BNTs have significant strength advantage over present state-of-the-art nanomaterials. The innovation proposed is to develop a method and design a reactor prototype for producing BNTs from readily available, environmentally friendly, materials and chemicals. The approach for this prototype will utilize an amalgam of internal company know-how in nanomaterials and successful data from academia to create realistic and achievable action plan for the design of the reactor. UGP's success will mitigate the issues with heavyweight engineering materials usage, low corrosion resistance, instability at high temperatures experienced by operational environment exposed coatings in military materiel. In later phases of this project, BNTs produced by UGP will surpass competitive technologies (aramid fibers, carbon nanotubes) as the choice for strengthening lightweight composites, with improved mechanical properties. Phase I activities will include: investigating methods for producing BNTs, developing a reactor prototype diagram, and procedural instructions for proper handling and storage, and prevention of material degradation. |
