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 ...

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 ...

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 ...

A compact, reliable, efficient and inexpensive crycooler requiring less than 1kW of power for 2W of colling at 10K will be developed and demonstrated. This performance is at least twice as efficient as the best current state-of-the-art for smalllow-temperature crycoolers. The proposed technical approach, whose feasibility has been investigated and confirmed in Phase I of this project, is to appl ...

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 ...

One of the primary processes used for device patterning in the electronics industry is deep ultaviolet photolithography. However, the highly reflective substrates require reduction of this reflectivity to minimize standing waves and to maintain tightdimensional control. Most of te industry uses anti-reflective coatings (ARCs) which are applied using the spin coating technique. Unfortunately, spi ...

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 ...

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 ...

Currently available handheld mine detectors are effective in detecting metal mines and pieces of metal used in the firing mechanisms of non-metallic mines. However, these detectors can have a very high false alarm rate due to an inability to discriminatetargets, particularly the types and shapes of small metal-firing mechanism parts, and they are not effective at localizing small metallic targets ...
