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: 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: Resodyn Corporation proposes to develop a portable, cost effective, near-surface residual stress measuring tools based on electromagnetic principles. Resodyn Corporation has patented technology developed for validating cold expanded button head rivet holes.The first application in Phase I is to apply this technology to countersunk cold expanded rivet holes in 7075 aluminum. In Phase I ...

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 ...

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 ...
