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: 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: 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 ...

The purpose of this Phase II program is to develop an innovative, low cost, all-in-one surgical instrument for performing cricothyrotomies and managing airway trauma on the battlefield, with improvements aimed at ultimately reducing mortality rates associ

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 ...

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, caused by constant short-travel, high-frequency movement to maintain level flight, can also induce wear on actuator components.The Air Force and co ...

The purpose of this multi-phase program is to develop an innovative all-in-one surgical instrument for performing cricothyrotomies and managing airway trauma on the battlefield, with improvements aimed at ultimately reducing mortality rates associated with these procedures. The Wolf QuickCric is designed to be a substantial improvement over the cricothyrotomy kits that are currently used by medic ...

ABSTRACT: Modern military aircraft are encountering major thermal obstacles as a result of significant increases in on-board heat generation combined with a reduced ability to transfer heat to the ambient environment. Adaptive power and thermal management systems (APTMS) are being studied in great detail in order to mitigate these thermal restrictions, but complexity of such systems necessitates ...

Techshot is pleased to provide this proposal utilizing our scaffold fabrication and regenerative medicine experience together with Dr. Boland?s longstanding research interest in developing a tissue engineered vascular graft. We are proposing an off the shelf bioactive vascular graft capable of remodeling in situ to provide a long term solution to revascularization due to traumatic injury. In t ...
