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: 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: Data integrity is essential for accurate and deterministic decision making in diverse military and commercial digital systems, and the most common cause of electronic data corruption for many of these systems is electromagnetic interference (EMI). Unexpected and unmitigated EMI, especially from high power systems (HPEMI), can cause deleterious effects ranging from subtly incorrect calcu ...

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: VSI proposes the development of the SIGMA (Speedy Imagery Geo-registration and Motion Analysis) system, which will address three key requirements by the end of Phase II: (i) adapt to different type of sensors, sensor-configurations and sensor operating conditions, (ii) handle large amount of data in real-time or close to real-time using limited resources, and (iii) operate under conditi ...
