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:Echo Ridge and partner Wright State University (WSU) propose to prototype and evaluate the Phase I-developed novel performance enhancing signal processing algorithms enabled by dynamic spectrum access (DSA)-based cognitive radio (CR) and GPS navigation functionality operating on a common software defined radio (SDR) platform in a cognitive network (CN) (Elemental SDR-hosted Cross Applicat ...

ABSTRACT:A chip carrier for high power density electronics made from low CTE materials and embedded with an oscillating heat pipe will be applied to a real world satellite electronics device to transform high heat flux (e.g. 100-300W/cm2) at the device package to a lower heat flux at the heat sink areas - and do so with minimal thermal resistance. Deliverables at conclusion of two-year effort will ...

ABSTRACT: The objective of this proposal is to develop blast cleaning enclosures (BCE) that eliminate exposure to hazardous materials (HM) due to substantial migration in and around the enclosure to increase the occupational health and safety of Air Force personnel. To achieve this cleaner safer BCE, typical operations and enclosures will be examined to identify mechanisms of HM generation and m ...

ABSTRACT:In this Phase II effort, nGimat will utilize its newly-developed FAFS technique to sinter ceramic films to metal substrates.The FAFS method was developed and proved feasible through a Phase I SBIR grant and we will expand our understanding of the technique through thorough R&D in Phase II.Sintered samples will undergo thorough surface and mechanical analysis to validate the FAFS process.S ...

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 Air Force"s Air Logistics Centers (ALCs) are charged to maintain the fleet at maximum readiness. In order to achieve this goal, the ALCs perform aircraft scheduled maintenance using well-defined planning and scheduling processes and procedures by assigning MRO tasks to minimize the time an aircraft spends at the depot and the associated maintenance costs. However, the current system ...

ABSTRACT: Aircraft damage resulting from environmental exposure and fluid leaks constitute a major portion of the costs associated with aircraft repairs and lead to significantly reduced mission readiness. The ability to identify contaminant exposure within airframes and inform maintenance personnel of leaks, corrosive environments, and chemical contaminants in difficult to access areas will all ...

ABSTRACT: Prime Photonics is developing an ultrasonically enhanced magnetic field detection system that will measure defects, voids and residual stresses in ferrous and non-ferrous materials. Successful development and deployment of this technology will enable on condition replacement of critical components, increasing safety and reducing cost. This product can also be part of an integrated logis ...

ABSTRACT: Gun barrels have a variety of failure modes that must be monitored over the life of a barrel. Fatigue cracking is one of the most critical failure modes and can result in catastrophic barrel rupture if not detected and addressed. Currently, there is no existing NDI method or equipment to assess fatigue cracking within the barrel wall. Luna"s proposed technique has the advantage of autom ...
