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:This effort will provide both a rapid, satellite thermal modeling tool and deployable radiator system specific to Responsive Space needs. The thermal analysis tool will allow users to make rapid decisions and apply appropriate hardware from a specific RS thermal toolbox. The deployable radiators, being a key component of this toolbox, will provide near isothermal radiator surfaces and a h ...

ABSTRACT:A new differential spectroscopic technique is proposed to detect VOCs for environmentalmonitoring and remdiation at Edwards AFB. This new technique has demonstrated promisewith similar materials and can be deployed in a modestly sized unit to providecontinuous monitoring.BENEFIT:This technology is applicable to various types of monitoring application and is anorthogonal signature that com ...

ABSTRACT:Radio-frequency (RF) transmitting devices are found nearly everywhere today, ranging from lower-power cell phones to radar equipment to high-energy weapons systems. Accidental exposure of humans to the RF radiation emanating from these devices can cause harmful thermal effects including tissue damage or death. Modeling these thermal effects across a whole population of humans is difficult ...

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: In this Phase I SBIR project, the Athena Group, Inc., will develop a mathematical framework and expert system design tool for robust and highly efficient filter design. The developed tool will be capable of designing filters that have challenging requirements, such as sharp transitions, narrow subbands, and/or complicated passband structures. The developed expert system will be able to ...

ABSTRACT: The Air Force regularly uses eddy current and ultrasonic NDI equipment which can be configured with a wide range of battery chemistries. Many of these battery chemistries, which include toxic heavy metals, are detrimental to the environment and can be difficult and costly to dispose of. The Air Force is seeking a new power supply for applicable NDI equipment that reduces the environment ...

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: 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: The primary objective of the Phase I project is to establish the feasibility of applying a methodology to assess a candidate legacy part to determine the viability of using Additive Manufacturing methods to produce the part. This objective will be accomplished by creating a guided decision framework that determines if a part aligns with the critical process characteristics and economic ...
