The United States Marine Corps (USMC) is pursuing high-performance aluminum castings for structural components of the Expeditionary Fighting Vehicle (EFV). Aluminum alloy A206 has been considered for these applications; however, this alloy is susceptible to hot tearing during casting, and has inferior stress-corrosion cracking (SCC) resistance. Under this proposed SBIR program, QuesTek Innovations ...

Flight-critical components in aircraft and helicopters experience complex service and loading conditions comprising of spectrum (variable amplitude) loading during their lifetime. Due to complex interaction of several life-limiting factors during spectrum loading, particularly, multiple fatigue damage mechanisms and microstructure sensitivity, development of analytical models to accurately predict ...

The Navy seeks an in-situ powder coating material and application method for spot repair. Resodyn Corporation proposes a unique restoration and repair polymer thermal spray coating (R & RPTS) system that provides the ease of repair, safety in handling, and effective coating protection to fulfill the Navy needs. The proposed system will be a zero VOC, non-toxic, non-chromated material with the pote ...

Work proposed for this Phase I involves utilizing existing EBDM technology with newly incorporated closed loop process controls to develop optimized parameters for thermal management of the process intended to improve microstructure and mechanical properties over those previously obtained using high deposition rate parameters.

The objective of this proposal is to demonstrate the feasibility of an energy efficient Environmental Control Unit (ECU) that significantly reduces generator fuel consumption at military forward operating bases (FOB). This system, coined Remote Environmental Control Unit (RECU) promises to provide a reliable supply of conditioned air to tactical shelters without the use of conditioned air ductwork ...

Delcross proposes to systematically validate the Savant and Savant-Hybrid solvers for a wide variety of problems. When shortcomings in existing methods are identified, they will be investigated and revised as necessary to provide good comparison with benchmark solutions. Our approach will first consider canonical problems involving PEC structures that are well understood. We will use Savant and a ...

Modern military and commercial aircraft include numerous RF systems and associated antennas. The designed freestanding performance of antennas is typically degraded by their platform installation. Also, the cositing of many RF systems in a small region creates enormous opportunity for inter-system EMI via antenna coupling that can significantly harm receiver performance. As challenging as these pr ...

Unfortunately, existing AlGaN based ultraviolet laser diodes with wavelengths much shorter than 340 nm suffer from poor performance. This is partially due to the fact that most of the existing research has focused on growth of InGaN lasers on GaN based templates, but a large part is also due to material and processing issues unique to deep UV lasers. New approaches to achieving III-Nitride 280 nm ...

A development program is proposed to address failures experienced on Navy actuators exposed to severe vibration levels. A failure investigation and root cause analysis will be performed to help determine the best approach to improving the design. New design concepts will be built and actual vibration tests will be performed using a Curtiss Wright actuator assembly. Ingenium will leverage experienc ...

The High Load Roller Bearing (HLRB) roller for severe service offers a zero-maintenance reliable replacement for bearing sets currently utilized on DDG-51 helicopter bay hanger doors. Enhanced seal design prevents the ingress of liquids and particulates even under extreme environmental conditions and extreme off axis loading. Intended as a direct replacement, modifications to ship doors or structu ...
