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: Silicon-based lasers/detectors have long been desired for owing to the possibility of monolithic integration of photonics with high-speed Si electronics and the aspiration of broadening the reach of Si technology by expanding its functionalities well beyond electronics. The goal of this project is to first develop high quality SiGeSn material and then use it to demonstrate prototype opt ...

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: The goal of head-worn display systems is to increase situation awareness and reduce operator workload. The urgent need is for higher image resolution and lower system latency, while meeting constraints on head-borne weight and power. Current processor solutions cannot meet increased requirements. The challenge is that power consumption is proportional to the amount of data being handled, ...

The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase II project is to develop a new microscope that integrates biodynamic imaging with conventional phase contrast microscopy for use in drug development and other research applications. Accurately capturing the signatures of three-dimensional biological systems provides more realistic measures of drug effic ...

The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase II project derives from the fact that increasing the reliability and robustness of cyber-physical systems (CPSs) will directly increase their adoption in real world applications. CPS technology is directly applicable to a broad range of sectors, including utility grids, smart buildings, manufacturing, h ...
