| Title: | Innovative Manufacturing Process for Defect free, Affordable, High Pressure, Thin Walled Hydraulic Tubing for Navy Aircraft |
| Abstract: | The objective of the technical effort is to eventually identify a material and a process that produces thin wall high pressure tubing for high performance aircraft, specifically Navy aircraft. The need for improvements stems from disastrous failures and the subsequent failure investigations that have indicated a need for a more fracture-tolerant tubing material. The first phase of the effort will consist of four distinct activities: 1. Titanium Alloy, TI-425.will be evaluated as a replacement material for Ti-325, the alloy used in current high pressure hydraulic tubes. The former is a relatively new alloy, stronger than Ti-325, with good cold-working performance. This activity will use flat plates. The goal is to identify an oxygen level and thermal treatment that results in a condition such that the 425 alloy is still stronger (and more crack resistant) than the 325 alloy while, exhibiting superior ductility ( and thus, workability). 2. Manufacturing studies will be conducted with major Titanium suppliers to insure that the research results can be economically transferred to large-scale industrial practice 3. Systems-level studies will be held with a major aircraft manufacturer to determine the impact of the change in tubing material on systems performance. 4. Liasion will be established with laboratories involved in Pressure Impulse Testing |

| Title: | Novel Alloys and Innovative Low Cost Manufacturing Process for Defect Free, Improved, High Pressure Titanium Hydraulic Tubing for Navy Aircraft |
| Abstract: | This Phase I SBIR proposal addresses the Navy's need to improve the reliability and safety of titanium thin-walled, high pressure hydraulic tubing used in naval aircraft. Powder metal processing will be used to produce novel, cold formable titanium alloys that are more damage resistant and damage tolerant than the standard tubing alloy, Ti-3Al-2.5V. Tubing will be produced from P/M tube hollows and evaluated to establish the technical feasibility of using P/M tube hollows as starting stock to produce titanium hydraulic tubing. In Phase I several innovative titanium alloys will be evaluated for cold formability, damage resistance and damage tolerance by; smooth and notched tensile properties, scratch hardness, indentation hardness, microstructure and chemistry. These tests will identify the most promising alloys for the production of hydraulic tubing and establish the initial economic and technical viability of making tubing from P/M tube hollows. Impulse tests and low cycle fatigue testing of tubes will be conducted in the Phase I Option to establish that tubes produced from the alloys developed in Phase I are indeed superior to Ti-3Al-2.5V. The proposed technology will answer the need for affordable, damage resistant and damage tolerant titanium thin-walled high pressure hydraulic tubing for military and commercial aircraft. |

| Title: | DRIFT ProcessThermoplastic Composites Materials & Innovative Manufacturing Process for Thin Wall, High Pressure Hydraulic Tubing for Navy Aircraft |
| Abstract: | Great Lakes Composites will utilize its extensive background in thermoplastic composites materials to provide an innovative solution to develop a high pressure, thin-walled hydraulic tubing for Navy aircraft. GLC will utilize the patented Direct Re-Inforced Fiber Technology (DRIFT) process to heat fuse thermoplastic resin to continuous fibers, to efficiently and thoroughly impregnate the fibers without damage, improving the reliability and safety of hydraulic tubing. GLC anticipates that thermoplastic composites tape-form materials, wrapped to form the tubing, will exceed the Navy's expectations, as well as significantly reduce failures. The additional benefits of cost and weight reduction, along with re-formability in the field will further contribute value-added benefits for both the Navy and potential commercial markets. The resulting properties of the thermoplastic composites materials tubing will include a minimum of 5000 psi, a continuous use temperature of greater than 400◦ F, an outside diameter of 0.25" to 0.75" with a wall thickness of 0.022" to 0.065" respectively, and a minimum of 10 feet to 30 feet or more in length. It is anticipated that the resulting thermoplastic composites materials tubing will have zero degradation of properties under continuous exposure to hot hydraulic fluids and be resistant to `chafing' of the outer surface. |

| Title: | NDE for Residual Stress Relaxation |
| Abstract: | Fatigue lives of rotating engine components are greatly enhanced through application of shot peening and other processes that impart residual compressive stresses to their surfaces. X-ray diffraction measurements, however, confirm that these stresses relax during service. Furthermore, residual stresses may relax rapidly or gradually and can vary by location. This proposal addresses the need for a nondestructive method of measuring and tracking residual stress relaxation with scanning MWM-Arrays. JENTEK's patented MWM-Arrays have demonstrated capability to measure shot peen quality in nickel alloys and we are confident we can transition a solution for stress relaxation tracking in nickel alloy components, within two years. This proposed program will also address stress relaxation in titanium alloys. JENTEK currently has two active programs that will provide leverage to this program. Under Air Force funding, we are adapting our technology for manufacturing quality assessment of Low Plasticity Burnishing and Laser Shock Processing. Under a separate Air Force program, we are adapting our technology for IBR inspection for cracks and mechanical damage. Scanning MWM-Arrays, already integrated into automated engine disk inspection systems in use at Navy depots, have the potential to provide crack detection and residual stress relaxation tracking with a single inspection. |

| Title: | Residual Stress Measurements Program to Support Condition Based Maintenance (CBM) of Critical Rotating Components of Propulsion Systems |
| Abstract: | Surface enhancement processes are extensively used to introduce compressive residual stresses (CRS) and enhance the fatigue performance in titanium and nickel alloy rotating components for Navy propulsion systems. CRS can relax in rotating components as a result of thermal exposure and cyclic stresses, adversely impacting the fatigue life and strength. Relaxation can occur rapidly depending upon the relative component temperatures and cyclic stresses. Inspection of the components is performed on a routine basis to characterize damage levels in accordance with Technical Manuals (TM). However, the CRS are currently not monitored and tracked during routine inspection. As part of the inspection cycle, components are re-shot peened to overcome any residual stress relaxation that may have occurred. Intervals at which the components are re-peened may or may not be appropriate for the rate of compressive relaxation. A portable XRD measurement device capable of quickly quantifying the CRS would allow the Navy to track the surface residual stress in support of condition based maintenance of critical components. The measurement device would allow for field measurement of critical features of blades and disk components. The device would be capable of not only measuring the surface residual stress but also the cold working which has a significant impact on the rate of relaxation. |

| Title: | Smart Sensor Hub for Corrosion Monitoring |
| Abstract: | Corrosion of aircraft and rotorcraft is the single largest maintenance cost driver for the Navy and Marine Corps. In order to maximize aircraft availability and minimize inspection and maintenance demands, Luna proposes to develop a smart sensor hub to support corrosion monitoring of aircraft. The sensor hub will be the central application device for a complete corrosion monitoring system that detects early stages of corrosion and estimates corrosive severity. The smart sensor hub will perform wireless network communications, transducer communications, and data conversion and application functions. It will also provide power management to the transducer circuitry and energy scavenging devices to maximize service life. The system will have an open architecture and configurable interface with loading options to accommodate the widest possible range of sensors. Luna's corrosion monitoring system will fuse diverse datasets for improved state awareness and reduced uncertainty in measuring corrosion damage and estimating useful life remaining. The Phase I program will conclude with a breadboard demonstration of the functional elements of the smart sensor hub including power management, control and communication, and data storage. Luna will also demonstrate corrosion sensor response to early stage corrosion damage of aircraft alloys |

| Title: | Miniature Corrosion Sensor Hub to Monitor Difficult-to-Access Aircraft Structure with Complex Geometry. |
| Abstract: | MSI specializes in design and commercialization of miniature intelligent low power instrumentation systems that process data from sensors in scripted Bayesian algorithms in a "rules engine" application. Recently MSI received a US patent a new monitoring methodology for difficult-to-access aircraft structure with complex geometry. Our product will incorporate a tiny processor and a power scavenger circuit in a tape that supports ribbonized sensitized fiber strands. The ribbonized sensitized strands will extend around, under, and on a structure such as a magnesium gearbox housing, a highly complex geometry casting up to 3 cu ft in size. Deterioration or damage to the ribbonized strands will indicate, probabilistically, that damage is occurring to the item under test. The sensor hub will incorporate a low power electronic circuit called the Embeddable Programmable Instrumentation Circuit (EPIC) which is designed for creating stand-alone low power monitoring systems for aircraft and ground vehicle CBM and PHM. The EPIC processor is very low power, capable of being powered by a energy scavenger circuit. The new module will support intermodule wireless communication, and provide interrogation and wireless offload of the state of health of the equipment being monitored to the inspector's handheld or PC. |

| Title: | Miniature Corrosion Sensor Hub to Monitor Difficult-to-Access Aircraft Structure with Complex Geometry. |
| Abstract: | Embedded wireless sensors for corrosion monitoring of critical aircraft components are needed for improved condition based maintenance and future structural health monitoring (SHM) systems. The objective of this Phase I SBIR proposal is to design, develop, and test a corrosion measurement and data collection system that can utilize multiple types of corrosion sensors. A key design criterion is that the system be extremely low power which will enable its use with energy scavenging power sources, such as vibration based energy harvesters. The basic architecture incorporates a hub which manages data collection and storage from multiple distributed remote corrosions sensing nodes (CSN's). Communication between the hub and the CSN's is achieved using a micro power variation of the RS-485 bus architecture, which allows for up to 256 distributed nodes. The hub incorporates high density non-volatile flash memory for data storage and utilizes an IEEE802.15.4 radio link for offloading the collected data to a remote handheld or personal computer. The CSN's can employ any type or corrosion sensing method, including resistive, electrochemical impedance spectroscopic (EIS), and inductive techniques. Future distributed nodes could be developed that support various other structural sensors, including strain, pressure, and vibration sensors. |

| Title: | 3D Optical Defectoscope System |
| Abstract: | To address the Navy need for a cost-effective nondestructive evaluation system to facilitate high rate, high-precision inspection of hybrid ceramic bearings, Physical Optics Corporation (POC) proposes to develop a new 3D Optical Defectoscope (3DOD) system based on shearing of scattered light from defects of ceramic elements. The 3DOD performs precision 3D mapping of surface and subsurface defects in ceramic elements at a high operation rate. Innovative implementation of shearography, polarization control, and new optical design, all of these make 3DOD applicable for inspection of ceramic surface features. Implementation of shearography, which is a proven NDE method, offers robustness against environmental disturbances, optical alignment, and high sensitivity to detect defects with a resolution of 0.2 microns. The 3D defect measurement provides high detection probability, with very low false negative and false positive rates. The 3DOD design includes fiber optic bundles and a universal handling module that makes it applicable for both rolling and ball ceramic elements. In Phase I POC will demonstrate the feasibility of the 3DOD prototype by 3D defect mapping for ceramic rolling elements. In Phase II, POC plans to develop an automated prototype for inspection of ceramic ball bearings. |

| Abstract: | The objective of this proposed effort is to demonstrate the feasibility of Vibrant Corporation (Vibrant) improving current non-destructive evaluation (NDE) methods to allow for surface and subsurface feature inspection of hybrid bearings. Under the proposed effort, an NDE capability will be developed and demonstrated that can quickly and cost effectively detect various types of manufacturing defects found in ceramic rolling elements used in hybrid bearings including surface and bulk flaws. The NDE capability will be adapted from the Process Compensated Resonance Testing (PCRT) technology currently used for metal and ceramic parts in the automotive and aerospace industries. PCRT uses Resonant Ultrasound Spectroscopy (RUS) coupled with genetic sorting algorithms and the Mahalanobis-Taguchi statistical method. PCRT is able to determine patterns within the resonant spectra of acceptable and unacceptable parts. These patterns will then be used to generate a sorting tool that can consistently separate parts with any combination of acceptable variations from those with a single occurrence of an unacceptable variation, i.e. critical flaw. |

| Abstract: | Impact Technologies, in cooperation with The Boeing Company and IMR Test Labs, proposes to develop a low power, lightweight, miniature sensing device capable of sensing parameters which contribute to corrosion development in aircraft structures and components. By monitoring the primary drivers of corrosion as opposed to only its formation and effects, maintainers will be able to more proactively address corrosion within a more prognostic condition-based maintenance framework. The Phase I program objective is to demonstrate a prototype Corrosion Sensing Module (CorrSeM) for monitoring environmental factors contributing to corrosion development. Impact will leverage its experience in developing in-situ embedded sensing solutions to architect, design, and build a prototype system for laboratory data collection and demonstration of Phase I feasibility. The ability of the prototype to track corrosion drivers will be verified through controlled ISO and ASTM test methods. At the end of Phase I, Impact will create a development plan leading towards inexpensive, lightweight, miniature solutions which meet or exceed performance expectations. Successful completion of Phase I objectives will allow for smooth transition into a Phase II program focused on rigorous testing of the CorrSeM's capabilities under both laboratory and real-world scenarios and the development of miniature CorrSeM prototypes. |

| Abstract: | Corrosion of aircraft and rotorcraft is the single largest maintenance cost driver for the Navy and Marine Corps. In order to maximize aircraft availability and minimize inspection and maintenance demands, Luna proposes to develop a miniature, light weight sensor suite that will measure corrosive severity of aircraft operational environments. The smart corrosivity sensor suite will monitor multiple environmental parameters and quantify cumulative corrosive effects that an aircraft experiences. The light weight and small size of the self contained sensor suite will permit instrumentation of critical components and "corrosion hotspots" within the aircraft. The sensor suite will be designed as a smart transducer interface module for compatibility with a network capable application processor such as the miniature corrosion sensor hub (Topic N07-169). The sensor suite will be a low power device for long life use with a battery or energy scavenging module (Topic N07-178). Luna's environmental corrosivity sensor suite will fuse measurements of environmental parameters and corrosivity for improved state awareness and reduced uncertainty in estimating coating system breakdown and structural material damage. The Phase I effort will be concluded by demonstrating the correlation of the breadboard prototype sensor suite response with corrosion of aircraft alloys in accelerated environmental corrosion tests. |

| Abstract: | To address the Navy's need for an environmental sensor suite to monitor corrosion-influencing parameters for aircraft structural materials, Physical Optics Corporation (POC) proposes to develop a new Miniaturized Fiber-Optic Spectroscopic (Mini-FOS) Corrosion Sensor system. This system is based on fusion of several environmental and chemical sensors innovatively integrated on a single optic fiber for monitoring all relevant parameters simultaneously. The self-contained system will be compact (<1 ounce, <1 cubic inch) and powered by an energy scavenging circuit to generate 1 mW/cc. With a detection sensitivity of parts-per-billion for chemicals, ~0.01 degrees C for temperatures, and 0.01% for humidity, this system will collect and store data at a rate of at least one Hertz during flight. In Phase I POC will demonstrate the feasibility of Mini-FOS by investigating the system design by computer modeling, and fabricating and testing a breadboard prototype (TRL 4) in a simulated corrosive environment. In Phase II an advanced, miniaturized Mini-FOS engineering prototype with TRL 5 will be assembled and tested both at POC and at a Navy facility. |

| Abstract: | Arizona Paradrogue Systems, a drogue coupling assembly, a drogue coupling assembly development and manufacturing firm and SySense, Inc, systems development firm specializing in navigation and control design for autonomous air refueling systems have teamed together to develop a fully stabilized and controllable drogue. APS and SySense plan to generate an analytical model of a stabilized/controllable drogue through numerical analysis simulating tanker, receiver and drogue bodies in turbulent air as well as navigation and electro-optical devices as sensors to provide control and feedback information to actuators installed on the drogue. The design will be based on existing APS drogue designs and will bolt on to existing drogue refueling systems requiring no additional mechanical modifications to the hose/reel system. Phase I investigation shall focus on using the C-130 high speed basket as the model in order to demonstrate the concept. Transverse force data on the drogue shall be obtained through wind tunnel testing using a basket modified with manual devices to simulate canopy manipulation. This data shall then be combined with sensor and navigation data to complete the analysis. The Phase I option shall expand the analysis to include C-130 Low Speed basket, Buddy Store and Variable Speed Drive. A full scale prototype will be constructed to demonstrate the concept in the Option phase. |

| Abstract: | Nielsen Engineering & Research (NEAR) is proposing to develop an innovative controllable drogue system based on their CDC7 technology. During the Phase I effort, a second generation CDC7 design, which meets the Navy's specific needs, will be developed through numerical analysis and full-scale wind tunnel testing. System feasibility will be demonstrated through dynamic simulations that include the tanker, hose, controllable drogue, sensors, receiver, and atmospheric turbulence. These analyses will demonstrate that NEAR's controllable drogue system can maintain the refueling basket at a specified stabilized location relative to the tanker even in severe atmospheric conditions. In addition to this aerodynamic performance, the proposed drogue system is reliable, durable (minimizing FOD potential), lightweight, compatible with existing USN/USAF refueling systems, and requires no receiver modifications. While the proposed work plan is very ambitious, it is made achievable through the use of 1) NEAR's existing refueling technology and numerical modeling capabilities, 2) a development team with significant experience in the field of aerial refueling, and 3) external funding from a commercialization partner that is established in the aerial refueling industry. The Phase I program will provide a strong foundation for subsequent development and flight testing of the controllable drogue in the Phase II contract. |

| Abstract: | With improvements in high performance military jet aircraft engines and the increase in complexity of the exhaust systems the noise produced has become problematic. Reducing these noise levels, while maintaining overall system performance, has become the driving issue in new nozzle designs. This proposal will focus on nozzle designs of practical application that can be implemented on current high NPR engine configurations, such as chevrons (or serrations) cut into the trailing edge of the nozzle. In Phase I we will address the practical aspects of making the noise/performance tradeoff for high pressure ratio nozzles. Data will be collected on models in a subscale test facility and evaluated using near field holography and shadowgraph imagery to identify the source characteristics. This will aid development of both CFD and noise prediction algorithms in Phase II. |

| Title: | Exhaust Jet Noise Reduction for Tactical Aircraft |
| Abstract: | A class of high amplitude and high bandwidth actuators called localized arc filament plasma actuators (LAFPAs) have recently been developed at OSU and used for control of high-speed and high Reynolds number jets. The control included successful noise mitigation in a Mach 0.9 jet and mixing enhancement (and very preliminary results for noise mitigation) in a Mach 1.3 ideally expanded jet. The control relies on high bandwidth of the actuators and excites various instabilities in the jet to achieve the goal of mixing enhancement or noise mitigation. The proposed Phase I work will explore the effectiveness of this technology in more practical supersonic exhaust jets operating with various flow regimes (i.e. ideally-, over-, and under-expanded) and high temperature. Phase I work will pave the way for detailed parametric study of the control issues to achieve maximum noise mitigation in Phase II, where we will also explore integration and commercialization issues. |

| Abstract: | The absence of a comprehensive, integrated aerodynamic/aero-acoustic modeling and analysis framework represents an impediment to achieving significant noise reduction within constraints imposed by the engine cycle, realistic geometry, and airframe. We close the gap by developing a suite of advanced, high fidelity nozzle performance and jet noise-based tools integrated into a unified software package with validation cases and applicability assessments. The flow field software will be based on TTC Technologies, Inc. multi-disciplinary high-order CFD tool, AEROFLO, which predicts temporal and spatial flow fields at all speeds (subsonic, transonic, supersonic, and hypersonic). The tools, ranging from RANS to LES, will be installed as modules interfaced with a comprehensive set of aeroacoustic source modules populated with fundamental physics-based aeroacoustic and semi-empirical models, to allow a range of prediction methods via "pull-down" menus. A large-scale noise model based on a RANS/PSE approach developed by UTRC and Caltech will also be implemented. The simulation codes will be rigorously validated using UTRC acquired data with limitations documented in terms of accuracy, robustness, sensitivity, turnaround time plus recommendations for improvements. The tool will provide a comprehensive approach to the design and development of nozzle components that attenuate exhaust jet noise. |

| Abstract: | As a result of the environment in which they operate, Naval aircraft are subject to pervasive corrosion damage. On-board sensors can signal when corrosion may be occurring, but there is a need for a portable corrosion scanning system that can confirm the degree and location of actual corrosion damage. JENTEK's patented Meandering Winding Magnetometer sensors and arrays (MWM-Array) have proven capabilities for detecting and imaging corrosion damage on complex aircraft components, such as gear box housings and fuselage lap joints. They are thin and flexible, can be customized to suit the component and will conform to curved parts and areas with varying curvature. JENTEK has recently completed a NAVAIR funded Phase II program (Field Portable System for Electromagnetic Imaging of Cracks Under Fasteners ) that succeeded in integrating the functionality of the laptop computer into the impedance instrument and reducing the overall system weight from 28 pounds to 12 pounds. This proposed program will continue the design evolution to meet the Phase I goals of system volume less than 0.5 cubic feet and system weight under 10 pounds. Additionally, MWM-Arrays will be adapted to provide corrosion detection and imaging on specific components of interest to NAVAIR. |

| Title: | A Portable Corrosion Detector for inspecting Aircraft Structures with Complex Geometries. |
| Abstract: | Aging aircraft commonly suffers from several types of degradation including corrosion, cracking and lack of bonding. Severe corrosive environment of naval aircrafts results in corrosion as the fundamental reason for aging aircraft. A corrosion detection system, independent from geometrical complexities, needs to be developed to detect active corrosion. AE method can be used to detect corrosion growth on-line for periodically active corrosion or off-line for active corrosion during measurement. In this proposal, we propose to develop a hand-held detector using of state-of-the-art AE method to detect active corrosion growing on naval aircraft components. During the Phase I and Phase I Option periods of this project, we will demonstrate the feasibility of developing an AE system with optimized settings to detect active corrosion growing on naval aircraft components.

Our technology is an innovative integration of Spatial Phase Imaging (SPI) applied to both high-resolution video imaging and Terahertz (THz) imaging that captures full 3D volumetric analytical information of both surface and subsurface corrosion. The proposed detector is highly sensitive to submicron size defects such as corrosion in early stages much more effectively than any current technology. It will also provide quantitative volumetric data of corrosion location and severity. Each of the two technologies has been developed for other applications and has been proven to be very strong technology. We will measure the complex 3D geometries of the part and the small deformations that will occur on the surface and under layers of paint at the submicron level on the part. The system can be developed into a portable cost effective method to detect corrosion in critical parts before catastrophic failure. This proposed effort will determine the feasibility of integrating these technologies and establish a small handheld cost efficient corrosion detector and determine a path forward towards a Phase II effort. |

| Title: | Intelligent and Robust Sensor Network for Distributed Engine Control |
| Abstract: | The Full Authority Digital Electronic Control (FADEC) centralized architecture has become the norm in aero-engine control systems. This architecture, which limits the design choices, accounts for ~20% of total weight and acquisition cost of the engine. Any modification to the system hardware is costly and inefficient. The limitations of electronics in high-temperature environments is another major issue. Distributed control architectures together with enabling high-temperature sensors and standardized interfaces will be able to provide a future-proof platform for next-generation systems. Photonics technology, including standardized fiber-optic wavelength division multiplexing (WDM), is becoming increasingly prevalent in many commercial systems including aircraft. Many systems, including avionics, now use 10-gigabit fiber-optic Ethernet. Also in use in aircraft systems are Fiber Channel and Firewire. IFOS proposes to address the problem with the development of a fiber-optic communications and control architecture based on Dense WDM (DWDM) and providing standardized optical network interfaces on a highly-reliable bi-directional optical network. In Phase I, IFOS will (1) develop a backbone architecture design concept appropriate for aero-engine control systems supporting many sensors with standardized interfaces, including IFOS' high-temperature multiplexed sensors, and demonstrate its feasibility through performance calculations and simulations, (2) ensure the system design meets all requirements for engine control systems |

| Title: | Short Pulse Laser Texturing of Wear Resistant Surfaces |
| Abstract: | This program seeks to develop and optimize laser textured wear resistant coatings with adaptive solid film lubricants to protect and extend the life of aircraft engine components. Patterns of micron-sized dimples on surfaces act as reservoirs for smart, nanostructured solid film lubricants that adjust tribological surface properties in response to changing conditions to minimize wear. Optimization of the dimple depth, diameter, and pattern is necessary to obtain best performance from the adaptive lubricant. This program will determine that optimization for a variety of substrate metal and coating combinations of interest to DoD prime contractors. Best results from testing on coupons will be applied to realistic parts in an Option task. Based on Phase I results, projections will be made for processing costs and times in a production environment and estimates will be made of life cycle cost savings for target aircraft engine components. This program is a collaboration between a company with core expertise in laser ablation and surface texturing (MLPC) and a company with expertise in wear resistant coating deposition, solid film lubricants, and wear testing (TXI), with cognizance and input from a Prime Contractor (Rolls-Royce) that will provide an early commercialization transition opportunity for successful program outcomes. |

| Title: | Micromechanical Models for Dielectric Behavior of Ceramic Matrix Composites |
| Abstract: | The proposed program will enhance material and sensor models to provide improved understanding of dielectric property information regarding Ceramic Matrix Composite (CMC) material condition. These models are to be used to assess thermochemical degradation of CMC's and also to assess the condition of materials during manufacture. JENTEK has developed a family of electroquasistatic and magnetoquasistatic sensors and arrays that have successfully solved a wide range of previously intractable NDE problems. These sensors and sensor arrays use model-based inverse methods to estimate electromagnetic properties that are correlated with many conditions of interest, such as thermal degradation of component materials. JENTEK's Interdigitated Electrode Dielectrometer is being adapted for manufacturing quality control of CMC's. The goals of this Phase I program are to extend standard micromechanical models to predict dielectric behavior of coated fiber CMC's, to incorporate these models into anisotropic layered material representations for dielectric sensor models, and to relate composite constituent behavior with thermal exposure conditions. To address this need, we will work with CMC thermostructural modelers (MR&D), manufacturers (COI Ceramics), and an end user (Pratt & Whitney). In Phase II, we will refine the models to support in-service material evaluation and self-consistent prediction of dielectric, thermochemical, and structural behavior. |

| Title: | Micromechanical Assessment of Thermochemically Induced NDE Changes in Advanced Composites |
| Abstract: | The Joint Strike Fighter is considering the use of organic and ceramic matrix composites for high temperature engine components. Material coupons and flight tests have shown that when these materials are exposed to high temperatures in the presence of air, salt fog, and humidity they can react chemically. The chemical reactions may cause a significant loss in composite strength even though there is no physical evidence of damage. Standard non destructive evaluation techniques such as ultrasonics, radiography, and thermography have not been able to accurately identify and monitor the chemical changes. Fortunately emerging NDE techniques based on electrical resistivity, electromagnetics, and dielectric properties have shown promise in relating chemical changes to NDE signal. These techniques, however, are in their infancy and the measurements are sensitive to sensor design, scanning technique, and data interpretation. In order to develop the electromagnetic-based NDE methods into useful engineering tools, it is necessary to understand the theoretical dielectric properties of advanced composites. The development of a micromechanical model for composite dielectric properties will support the development of NDE techniques and standards that can monitor chemically induced changes in advanced composite engine components. Materials Research & Design proposes to build upon their demonstrated understanding of composite material theory and develop a micromechanical model that relates composite dielectric behavior to constituent properties, fiber volume fraction, and fiber orientation. The theory will be tested for feasibility by comparison to NDE signals measured on CMCs of interest. The program will be undertaken by a team of MR&D and Jentek Sensors, Inc. MR&D will develop the theory, debug the computer code, procure CMC specimens, define the test plan, correlate the data, and prepare the reports. Jentek, as a subcontractor to MR&D, will consult on the theoretical assumptions, measure the NDE response, and reduce the raw data. |

| Title: | Development of a Miniature, Vibro-Mechanical Energy Harvester for Powering Wireless Sensors |
| Abstract: | In the proposed work, we will develop a highly efficient and miniaturized vibration energy harvesting device suitable for use on drive system components of helicopters. The goal is to provide power to run a wireless corrosion hub and sensors (to be developed simultaneously in a separate program). The target power generating capability is 5mW under vibration conditions typical of steady state flight. The size and mass of the system will be miniaturized. Target metrics are 0.0.1mW/gram, and 0.5mW/cc. The harvester will be implemented using our proven strain optimized, resonating cantilever beam with Macro Fiber Composite piezoelectric elements. An integral energy harvesting circuit will be based on one of our two proven circuit designs, our Managed Switching design, or out Capacitive Discharge design. The principle technical challenges will be in minimizing the size and mass of the device while still achieving target power output. This will be achieved by stacking multiple layers of MFC material on the beam, and implementing design features to minimize the beam's stiffness. Ensuring long term reliable operation in hostile environments is a second technical challenge. We will accomplish this through careful selection of materials, and by incorporating environmental sealing and overload stops into the enclosure design. |

| Title: | XMR- A Novel Vibration Harvesting System for Wireless Sensors |
| Abstract: | Wireless sensors promise to reduce the Navy's aircraft maintenance costs via real-time monitoring of corrosion-prone components. The promise of wireless sensors lies in their reduced susceptibility to failure, reduced weight and configurational flexibility compared with conventional wired sensors. However, because of the costs of replacing batteries in sensors deployed in inaccessible locations, a significant challenge for wireless sensors is power. In this Phase I effort, TPL proposes to develop a vibration harvesting power system comprising a new vibration harvesting module developed at Washington State University and TPL's patent-pending power management and storage system. The new harvester design is highly efficient, tunable over a broad frequency range (several 10s Hz), relatively inexpensive to manufacture, and is no larger than a stack of 3 US quarters. TPL's power management system efficiently stores the harvested energy in electrochemical energy storage devices to efficiently meet steady state and pulse power loads (up to 500mW) as well as provide back-up power in the absence of harvestable vibrations. Designed for "ZigBee"-type applications, this system can be customized for any user-specified profile. Successful completion of the proposed effort will pave the way for a unique solution to providing power for the Navy's remote, wireless systems. |

| Abstract: | The lowered cost of maintenance, lowered weight, and reduced installation complexity of smart electric actuators continues to justify the transition from hydraulic actuation to EMAs/EHAs. This SBIR proposal will extend the advantages of EMA technology into high-temperature, high-vibration applications with a first commercialization target being the JSF F35 Lightning II aircraft platform. During the SBIR Phases I research, PCKA will collaborate with NAVAIR and Lockheed Martin to establish the actuator requirements. Once the requirements are defined, PCKA will identify suitable actuator architectures for the application and then optimize the design in terms of weight, reliability, maintainability, manufacturability, and cost. Key design constraints will be the thermal and vibration environment which may necessitate the use of specific motor technologies, high-temperature wire insulation, lubrication, and electronics. In Phase II, PCKA will fabricate a prototype of the optimal design and perform qualification tests including EMI/EMC, vibration, shock, and altitude. If successful, developed technologies will ultimately transition to DoD programs under a Phase III contract. |

With the advancement of electronics over the last several years, aircraft system integrators have been replacing electro-hydraulic actuation systems with electro-mechanical actuation systems. Electro-mechanical actuators are now being used to control flaps, open weapon, refueling and cargo bay doors and deploy landing gear (fly-by-wire concept). They are being used in every area on the aircraft where temperature permits, however, due to motor and electronic component material limitations the temperature environment is limited. The proposed electro-mechanical smart actuator utilizes several technologies specific to high temperature applications above 200 deg C. The proposed motor is a high temperature Switch Reluctance Motor with high temperature windings.

As an additional capability, our tool will provide both developers and verification specialists with a robust interactive query-driven program comprehension capability that will significantly reduce the overhead of manual code review. While our tool will be applicable to any large C or C++ code base, we will specifically address issues relevant to the analysis of code developed to the Software Component Architecture (SCA). Our Phase I effort will demonstrate the feasibility of our approach by developing an initial prototype. Particular points of emphasis in our Phase I prototype will be to demonstrate the flexibility and extensibility of our approach. In Phase II we will produce an advanced prototype applicable to third-party applications. The transition target for this system is the JTRS Testing & Evaluation Lab (JTEL) which maintains test capability and certifies code in support of the Joint Tactical Radio System (JTRS) initiative. We will be aided in developing a more robust commercial product and in identifying additional transition opportunities though our collaboration with Mercury Computer Systems who are supporting our proposal. |

The Reference Interface (RI) consists of a compilable (i.e. source code) definition of the interface standard, and is supported by a Reference Test Definition (RTD) which defines the functional test sequences to be applied to the RI. The SAIL software tool will verify multiple aspects of Interface Compliance: (1) Semantic Compliance, consisting of verification of compliance with the published interface standard (Reference Interface), and examination of the interface for extensions or sub-setting; and (2) Functional Compliance consisting of verification of basic functionality of functions or methods defined in the interface, and verification of error handling. SAIL will perform compliance testing relative to the Reference Interface while providing the user to extend and/or control tool perform through the following mechanisms: (1) User definition of standard interface (Reference Interface), (2) User definition of functional performance requirements, and (3) Plug-in extensions to the functionality verification portion of the tool. |

| Title: | High Temperature Superconductor Circuit Integration with CMOS Electronics on Sapphire |
| Abstract: | Various DoD systems are starting to incorporate superconducting devices for sensing and/or manipulating electromagnetic fields, from filters for shipboard communication systems, to superconducting transmission lines for use as a microwave power limiters, to the development of electrically small antennas. With the breakthroughs in the materials and fabrication technologies, it thus becomes feasible to design a system on sapphire with multiple HTS detectors, or analog filters alongside CMOS electronics, with the CMOS performing first stage amplification and/or feedback and/or digital signal processing, with only 10s of microns separating the two, both operating in the cold side. Such a system should have major performance advantages over the present state of the art. However, this effort has not been taken beyond the device concept demonstration. We propose to use the Peregrine semiconductor processing and ion damage Josephson junction fabrication technology to make monolithic devices with HTS detectors/filters integrated with CMOS electronics. The ion damage technology allows fabricating identical junctions with high reproducibility. This project seeks to take the technology to the stage where it is clear to industry that monolithic co-fabrication is viable for DoD systems. |

| Title: | RF-based Geolocation I/Q Data Rate Enhancement: SHIFTER |
| Abstract: | Real-time precision geolocation of COMINT signals of interest is a top priority in the GWOT. As communication signals and standards such as 3GSM, WCDMA, and CDMA2000 proliferate at unprecedented rates, the number of emitters is scaling dramatically. In the GWOT, almost any signal could be a potential signal of interest. The use of this kind of commercial technology and related technologies by extremists continues to expand dramatically. Clearly, the signals of interest target set is growing at a high rate. The Navy and the larger Intelligence Community is aggressively deploying fully interoperable net-centric systems for precision COMINT geolocation to help meet this challenge. It is reasonable to expect that sensor density will increase by a factor of 10 across the IC in the next five years. Consequently, current geo-processing techniques will soon become overwhelmed with signal data, will not be able to effectively manage high sensor counts and will have only a limited capability to simultaneously prosecute the growing class of high value targets. Addressing these challenges is the focus of this SBIR proposal, called SHIFTER. SHIFTER will "shift" the geolocation processing algorithms and processing hardware and software into the "high gear" needed to improve efficiency and scalability. |

| Title: | Networked Positioning of Unattended Ground Sensors using JTRS radios |
| Abstract: | Data Fusion Corporation (DFC) proposes the development of a prototype combat positioning system that will reduce fratricide, increase situational awareness (SA), and enhance combat effectiveness for UGS-to-Soldier based CID applications. The system design will use GPS, Tactical Unattended Ground Sensors (UGS), a modified-mobile adhoc network MANET, local ranging signals and a mesh network that will provide sub-meter position information, velocity, time (PVT) as well as ID. The sub-meter position is obtained using DFC's legacy innovative positioning algorithms that uniquely combine (in a weighted least squares sense) lower accuracy absolute positions with highly accurate relative positions. Furthermore, DFC takes advantage of the mesh rigidity where appropriate. The minimal configuration can be a mixed network of dynamic nodes with or without GPS. GPS receivers only need be single carrier (L1) receivers processing the lower accuracy CA signal. This can be accomplished without any infrastructure. Should L1L2 P(Y) code receivers, and infrastructure be available additional accuracy and robustness can be gained. DFC will leverage its legacy positioning algorithms, GPS signal generator software and GPS softªware receiver (Kober, W., 2004), implemented on a Field Programable Gate Array (FPGA), to develop this CID system. The original GPS software receiver design was sponsored in part by AFRL/SN, AFRL/MN and USASMDC. |

| Title: | Networked Positioning of Unattended Ground Sensors using JTRS radios |
| Abstract: | Unattended sensors are an important element of the Future Combat System (FCS) architecture. These include Unattended Ground Sensors (UGS), autonomous weapons such as the Intelligent Munition System (IMS) and miniaturized Unmanned Ground Vehicles (UGV) and Air Vehicles (UAVs). All of these applications have a requirement to use GPS for positioning. A "catch 22" exists between GPS security policy and operational security doctrine in cases where the system is left unattended or is not recovered (munitions excepted). While security policy requires a PPS solution, security doctrine states that PPS devices cannot be left unattended. Under this SBIR effort, NAVSYS proposes to develop a networked GPS positioning solution for UGS based on our patented TIDGET technology. The TIDGET uses COTS GPS components to capture a snapshot of GPS data which will be transmitted over the FCS network to an attended location with a JTRS radio where the GPS crypto processing can be performed. This allows a PPS solution to be calculated for the UGS without requiring crypto equipment to be left unattended in the field. We shall prepare a design for a Phase II system to demonstrate this capability and will provide simulation results to show the expected performance and network loading. |

| Title: | PSIBED - Parametric Structures for Integrative Backscatter models and Environmental Database |
| Abstract: | Understanding shallow underwater environment is increasingly important, but shallow water acoustic models depend on a large number of factors that interact in a non-linear fashion. There are many different acoustic back scatter models, but many of the models haven't changed in years and some of the new ones rely on stochastic methods. What's needed is a general acoustic model and environmental parameter structure that can parameterize existing models and associated environmental data, as well as act as a new acoustic modeling framework for shallow underwater environmental awareness. 21st Century Systems, Incorporated is pleased to introduce our parametric structure for integrative bottom backscatter models and environmental database (PSIBED.pronounced "seabed"). PSIBED develops a parametric space built on powerful geometric algebraic formalism for generalizing backscatter models as advanced layered sediment algebraic "versors." The PSIBED algebraic signatures are used to describe and integrate models with parameters and environmental databases. PSIBED uses a multi-dimensional Clifford Fourier Transform structure for representing complex underwater environments and handles propagation of uncertainty as a first class property of PSIBED. Preliminary experiments reveal the potential to obtain, store, and utilize acoustic bottom backscatter information. This technology will ultimately lead to better underwater systems for use by manned and unmanned systems. |

| Title: | Improved Slope Efficiency, Decreased Optical Loss Lithium Niobate Modulators |
| Abstract: | Lightweight, high-performance fiber-optic links with minimized power consumption could fulfill important antenna remoting functions on Navy platforms if the modulators were more efficient. A factor of ~ 3.2 improvement in slope efficiency could be gained by pinning down the cause or causes of the optical waveguide insertion losses that until now have limited the benefits accrued from increasing the electrical-optical field interaction length in the material. This program goal is to isolate the root cause of the optical loss dependence on ridge width in ridge waveguides in Z-cut LiNbO3. Once the root cause is understood, we can develop an approach to make the ridge waveguides that reduce the dependence of loss on ridge width. With such an approach we hope to be able to reduce the VŸ… by ~30% and the insertion loss by ~ 2 dB. |

| Abstract: | Rainbow Communications proposes to investigate a compact, highly efficient, low driving voltage, broad bandwidth, high extinction ratio, low optical insertion loss, zero frequency chirp, electro-optic modulator based on thin-film lithium niobate materials, selected domain inversion technique, and optical-wave and electrical-wave velocity matched traveling-wave electrodes configuration for applications in RF photonic links and optical communication. The proposed EO modulator will be capable of modulating the intensity of optical light up to 40GHz with sub-volt driving voltage and up to 20-dB extinction ratio. The total fiber-to-fiber insertion is as low as 3-dB with zero frequency chirp. Several unique features distinguish it. First, Rainbow will fabricate a Mach-Zehnder (MZ) interferometer waveguide structure on a thin-film LiNbO3 material. Second, the domain of one arm of MZ will be inverted by using Rainbow_s unique electrical poling process. Third, by using thin-film structure and optimized traveling-wave electrode design, this EO modulator can achieve both very broad bandwidth, over 40GHz and very low driving voltage, much less than 1-V with high extinction ratio. Fourth, by using Rainbow_s novel package design and optical-fiber to waveguide coupling optimization, overall optical loss is very low and the efficiency of proposed EO modulator can be reach very high. |

| Abstract: | In the past twenty-five years, electro-optic modulator technology has made significant advances in terms of performance. Modulator bandwidth, a key technical parameter, has been extended to 40 gigahertz in the commercial world and to 100 gigahertz and beyond in research laboratories. The greatest problem has been to achieve such bandwidths while still maintaining low drive switching voltage, low insertion loss, high linearity and high extinction ratio. Material electro-optic coefficient, optical loss, dielectric loss and permittivity all contribute to these parameters, with lithium niobate currently representing the best balance of materials properties. This Small Business Innovation Research Phase I project develops novel materials processing techniques that extract the maximum possible performance out of the lithium niobate electro-optic material. The new technology promises to substantially improve the performance capability of existing electro-optic modulators for Navy platforms. |

| Abstract: | Existing filter technology does not suit the mechanical and electrical needs for use in expendable buoy systems. Current diplexer designs do not provide adequate rejection of the high power transmitter signal within the receive channel within the specified size, weight and acceleration constraints required for the Navy Buoy System. The proposed research includes the analysis and simulation of a high Q transmit filter that provides the required 90 dB transmit to receive stop band attenuation with low insertion loss to the transmit signal. One potential solution, which leverages NuWaves' expertise in planar filters, utilizes an interdigital filter plated on a center circuit board. NuWaves' initial simulations prove the sufficiency of the above approach. Phase I deliverables include a trade-off analysis of the expected diplexer performance vs. the design parameters. The expected diplexer performance will be based on a non-ideal simulation which includes real-world resistances and parasitics. The mechanical aspect of the effort includes physical size and packaging, thermal heat dissipation, resistance to high G acceleration, and housing metallization. |
