ABSTRACT:Development and use of new composite materials is imperative for continued advancement of airframe and engine systems.In order to facilitate the accelerated insertion of new composite materials, there is a need for an improved analysis methodology that allows designers to reduce the time and cost associated with material and structural development and test programs.The goal of the propose ...

ABSTRACT: Currently, there is no certified, Voice over Internet Protocol (VoIP)-based solution for cross-domain voice and video. More specifically, combatant commands and other agencies have requirements to enable users across different security networks to initiate and receive direct cross-domain audio and videophone calls, and to participate in audio conference calls. To address this need, Tr ...

Advanced composite material systems are vital to the development of lightweight, multi-functional Army missile systems.In addition to reducing the weight of the structure, composite materials provide the ability to expand the function of the structure by tailoring stiffness and strength characteristics for numerous applications such as solid rocket motor cases, missile airframes, missile guidance ...

Widespread damage in aging aircraft is becoming an increasing concern as fleet operators are extending the aircraft service increasing the risk of crack-like damage of aircraft components. Predicting the exact fatigue life is a difficult process and fatigue life prediction based on crack length measurements can be grossly inaccurate mainly because the appearance of these cracks typically occurs ve ...

ABSTRACT:Emergence and feasibility for flexible body-worn electronics and particularly medical patches requires high performance electronics capability.The problem is that these new technologies must have flexible and conformal physical formats and conventional electronic components are not in any way flexible. In the CLAS Phase I program, a new flexible high-performance manufacturing and material ...

ABSTRACT:In our Phase 1 SBIR effort (Discourse Analysis for Insights into Group Identity and Intent), SAE conducted a pilot study to assess whether its suite of natural language processing techniques could be adapted to automatically extract meaningful discourse measures from extremist group literature (cognitive complexity, idea density, vocabulary diversity, and sentiments expressed toward in an ...

The frictional losses in a gear mesh can be reduced by including super-finishing in the final manufacturing process. Phase I simulation tests of a hypoid rear axle gear shows a reduction in traction coefficient of 50 percent from an"as ground"surface to a high quality super-finished surface. This level of friction reduction is consistent for both low and high speeds. Phase I shows that costly s ...

The area of thin film growth has progressed rapidly, producing many high performance new materials which require accuracy of their atomic composition to perform as expected. Any method to provide real time in situ information about the elemental composition of the growing surface is highly valuable for these new, complicated materials. Utilizing a new instrument design, the Phase I project team ...

This project address the fabrication of solar blind detectors from the MgZnO material system. Both MBE and MOCVD material growth techniques will be used for deposition of the required material layers. Simulation software we be used to aid in the design of the photodetector structure. Devices will be fabricated from the grown structures and their electrical and optical characteristics determined.

Phase II of this project will focus on developing, constructing and demonstrating the operation of an prototype Active Quiet Pillow for reducing interior noise in helicopter medical evacuation scenarios. The innovation is based on a strategic combination of active noise reduction (ANR) and passive treatment elements in a pillow style arrangement. Two performance objectives to be demonstrated inclu ...
