This STTR Phase II program will create novel devices and system designs, expanding upon the microring resonator based silicon WDM modulator designs and system concepts developed during Phase I. The focus will be on linear transmitters and analog fiberoptic systems, used to transmit and transform analog signals, based on the Linearized - Ring Assisted Mach Zehnder Interferometer (L-RAMZI) modulator ...

ABSTRACT:A joint experimental and computational project using a carefully designed, flexible test article is proposed to assess the velocity-coupled combustion response of a representative liquid rocket injector element to transverse acoustic disturbances. In the proposed Phase II, the response of an injector flowfield at supercritical pressure conditions will be simulated, measured, and reduced i ...

ABSTRACT:The Munitions Environment Signature Model being developed by TSC will provide munitions design engineers with a tool for exploring RF fuze sensor alternatives by modeling the dynamic multistatic coherent RF signatures of targets illuminated by munition fuze sensors at sub-millimeter wavelengths. Output generated by the MESM will be suitable for use with radar imaging techniques including ...

ABSTRACT: Stainless steel ballscrew components, such as those found in landing gear and flap actuators on the C-130 aircraft, experience wear and subsequent failure due to corrosion, contamination and foreign object damage (FOD). High"dither"conditions, where the actuator undergoes a constant short-travel, high-frequency movement to maintain level flight, can also induce wear on actuator ballscr ...

ABSTRACT: The thermal spray process has many inherent complexities within each sub-process including feedstock manufacturing, component surface preparation and masking, torch parameter selection, robot trajectory and laboratory coating evaluation. Each sub-process is governed by rigid specifications that provide thermal spray applicators with procedural and process guidelines throughout the appl ...

ABSTRACT: Aircraft fuel cells are flexible rubber-coated fabric enclosures for the containment of fuel within aircraft cavities. The overall envelope dimensions and locations of interface fittings and attachment elements such as lacing ferrules and hanger baskets are critical to the proper function and durability of the fuel cells. The existing method of dimensional inspection is to install the f ...

ABSTRACT: A challenge which continues to present a barrier to the utilization of AM and wide spread adoption is knowing when to use the technology. This is particularly problematic in aerospace and in MRO operations because the technology is still emerging, and knowledgeable, experienced practitioners remain in short supply and will likely remain so until the next generation of technicians and en ...

ABSTRACT: Assured Information Security, Inc. (AIS) proposes Endpoint-Operated Link-assured Security (EOLuS), an effort to develop a product with the capability for realizing continuous end-to-end trust (EtET) in a dynamic network a network in which every client would verify and monitor the trustworthiness of its peers prior to communicating sensitive information. After the successful completion ...

ABSTRACT: This Phase II SBIR research addresses an important and timely technological need, specifically the practical development and demonstration of a very low-cost, multi-frequency, multi-beam phased array subarray technology. This low-cost subarray technology is the fundamental building block required for the practical realization of a large hemispherical phased array useful for horizon-to- ...

ABSTRACT: In recent years, diversification of energy dependence on foreign oil has attracted the use of alternative fuels such as the Fischer-Tropsch jet fuels and hydro-treated renewable jet fuels. However, there are combustion stability issues with alternative fuels in the aircraft engines including augmentors. In addition, the U.S. military has been using JP-8 as the single battle field fuel ...
