Reliability and structural safety are major concerns in the design of next-generation space transportation and systems. Acellent Technologies, Inc. Proposes to develop and innovative, cost-effective and reliable built-in structural diagnostic system forlight-weight large-scale space structures made of composite materials to monitor their integrity during service thereby prolonging life span, red ...

Phase I revealed a high priority need for a human factorial lightweight protective helmet that extends an adequate personal communication system and 360 degree situational awareness, as well as ballistic protection of dismounted soldiers. The proposedresearch addresses two most critical design issues: (a) human factors concerns and, (b) practical concerns voiced by dismounted soldiers. A Design fo ...

A 24-month Phase II project is proposed to develop and implement models that capture the fidelity of high fidelity physics-based (HFPB) models in a fast-running format. It is anticipated that such models will be incorporated in certain modules of theModular Effectiveness/Vulnerability Assessment (MEVA) code developed for and currently used by the Air Force for assessing munitions effectiveness an ...

The goal of the Middle Game Localization Utilizing Air DeployableActive Receiver (ADAR) project is the development of the passivecapabilities of the ADAR buoy. The Phase I of the researchinvolved a thorough investigation of the potential for gains dueto enhanced ADAR passive processing through a simulation-basedanalysis, and the development of a prototype ADAR processinghardware and software suite ...

In the phase I program, Advanced Ceramics Research, Inc. (ACR) fabricated in situ metallic foams by using a unique water-soluble polymer blend and ACR's Extrusion Freeform Fabrication (EFF) method. When the green parts were heated for binder burnout, thebinder was found to foam and create uniform closed, high-aspect ratio porosity. The freeform fabrication also could create open porosity ranging f ...

The objective of this SBIR project is to develop enhanced capabilities to evaluate solid rocket motors (SRMs) using x-ray computed tomography (CT) inspection. In Phase I, approaches were defined for developing technology to improve CT inspectioncapabilities. In Phase II, the technology will be developed and incorporated in practical tools to be delivered to OO-ALC at Hill AFB, where Air Force mi ...

ATEC and TA&T, in collaboration with the University of Maryland, will develop a light-weight, low-cost ceramic-based, high heat flux microchannel heat sink device suitable for power electronics cooling applications. The combination of our uniquefabrication process and the incorporation of an active heat transfer enhancement technology(electrohydrodynamics, EHD) will provide an enabling technology ...

A comprehensive rigorous unified physical formulation and accurate efficient robust computation technique are described for simulating complex compressible viscous reacting multiphases flow phenomena which can affect or control the performance or signatureof a flight vehicle during al phases of operation. The method is designed to enable continuous seamless predictions for internal, external, and ...

Acoustic Bandgap (ABG) materials can serve as acoustic filters to reduce and/or modify acoustic signatures. This is made possible by the incorporation of specific internal geometries within ABG panels, that are produced using solid free form fabricationtechniques. Three different types of (ABG) materials are presented, with two selected for further investigation. Two specific applications are p ...

New results on false alarm characteristics from our research show that an estimate of a contact's effective target strength could be used as a very reliable classifier for near specular submarine detections. Exploiting this would require that theprocessing system be able to adaptively estimate transmission loss from source or receiver to an arbitrary position prior to classification. Initial ind ...
