ABSTRACT:Cognitive skills/capabilities are important for the military personnel to fulfill tasks and to ensure mission efficiency and success. In the past decade, there are abundant researches suggesting that non-invasive brain stimulation via transcranial direct current stimulation (tDCS) holds great promise to enhance a soldier's cognitive performances. Although models to predict the tDCS curren ...

Successful brake system performance during long mountain descents is critical. Prior test events can fail to successfully replicate the severity of the extended down grade conditions, leading to recognition that definition of successful operational tests is required. Therefore the development of an updated test procedure and development of a Brake Fade Warning System, both of which rely on a numbe ...

Liquid rocket engines may be run for repeatedly over extended periods of time, requiring active cooling. An efficient means of cooling LRE nozzles involves using the liquid fuel or oxidizer itself to provide the cooling, often referred to as regenerative cooling. SEA's liquid rocket combustion chamber and nozzle design code, TDK, can predict the heat transfer to the surface of the nozzle as a fu ...

The maturation of Titanium Matrix Composite into an affordable material system with production experience on the F-16 opens up a wide series of opportunities for improved propulsion performance. This SBIR builds on the baseline TMC demonstrations being conducted by FMW and ATK and extends them to advanced systems. The use of configured residual stress states and enhanced Titanium matrix systems ...

Combustion instability is one of the greatest development risks for liquid propellant engines. In developing a stable injector design, the risks arise from a variety of sources - limited modeling capabilities, poor scalability and the high cost of appropriate component test facilities. Sierra Engineering Inc. believes that much of the empirical data on the injection element's driving characteris ...

A method of utilizing 3D printed molds to produce low cost metal parts for obsolescence, engineering development prototypes, and low rate production is proposed for development and evaluation.This method is capable of producing parts of similar quality to mass production techniques such as green sand and lost wax casting at a fraction of the setup costs for those methods.

In response to Defense Logistics Agencys SBIR for Advanced Manufacturing Technologies, Sentient proposes to develop a life-cycle cost optimization tool based on its DigitalClone-ComponentTM (DCC) modeling technology.This tool will enable users to better understand the tradeoffs between manufacturing cost and performance/durability of the resultant components. This is particularly attractive for lo ...

The future propulsion requirements of the USAF will require substantial performance improvements, especially stage mass fraction as defined by the Phase III IHPRPT goals. The development and transition to production of titanium matrix composites (TMC) offer the potential of significant mass fraction gains for liquid engines. This program proposes the substitution of TMC into the impeller, which ...

ABSTRACT:Knobley Technical Associates Phase Il Advanced Solid Rocket Motor Technologies for Tactical Missiles program includes design, analysis, development and testing efforts to define and mitigate technical and operational challengesto be investigated and resolved for successful maturation ofthe performance enhancing burn-rate augment highly loaded propellant grain technology for next generatio ...

Due to their high specific strength and light weight properties, polymer matrix composites (PMCs) are increasingly used in a wide variety of military and civilian aircrafts. The mechanical strength of PMCs can be dramatically compromised when such materials are exposed to various heat sources during operation and maintenance. It has been shown that PMCs can lose up to 80% of their mechanical stren ...
