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:A Propellant Health Monitoring (PHM) Sensor for Solid Rocket Motors (SRMs) utilizes actual propellant components in a tiny new sensor called AgeAlert.These sensors provide real-time data corresponding to mechanical property degradation resulting from environmental aging of propellants.The sensors are mounted external to the propellant and automatically track degradation passively without ...

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: Oceanit proposes to develop multiphase composite materials using shockwave consolidation approach. New materials will have exceptionally high mechanical strength, thermal and electrical conductivity as compare to current state-of-art technology. Oceanit"s prior experience in designing and fabricating novel will be critical in the success of the proposed effort. BENEFIT: Design future ...

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: Global Technology Connection, Inc., in collaboration with its academic and industrial partners proposes to develop a hierarchical 3-tier fault tolerant architecture to improve aircraft reliability, safety, and availability. The hierarchical system will support autonomous decisions for aircraft mission modification, trajectory planning, and low-level controller reconfiguration. At the ...

ABSTRACT: Desired tactical requirements for unmanned aerial systems (UASs) exceed current capabilities for performance, reliability, maintainability, cost and supportability. Mission requirements such as extended endurance, increased power for auxiliary/sensor systems, and low altitude, low speed maneuverability are becoming paramount, specifically, in the 10,000 lb class of vehicles. These desir ...

ABSTRACT:Unmanned Air Vehicle (UAV) developers have limited marketplace options for motor speed controllers. The largest commercial controllers are generally limited to below 12 kW and battery voltages of less than 50 V, Although these are well suited to 800 Class helicopters and Giant scale fixed-wing aircraft, they are not powerful enough for larger UAV development. A few high-power options exis ...

Oceanit will continue developing and fabricating a low-cost obscurant nanomaterial. The ultimate goal for this material is to make an aerosolized cloud that can be deployed quickly between an incoming threat and the equipment and personnel being protected.

Oceanit proposes to demonstrate a capability that will reason over multiple sources of communications available in a tactical environment and provide a commander both organizational and operational recommendations to meet mission objectives.
