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 Phase I of the proposed program the term of ADMA Products Inc. Twinsburg, OH and the University of Idaho, Moscow, ID demonstrated the ability to produce low cost Ti-6A1-4V powder and are now evaluating plate produced via a powder metallurgy approach.Seven potentially low cost powder types were evaluated. (1) crushed Ti-6A1-4V machine turnings which were crushed after hydrogenation (2) crushed C ...

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 ...

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 ...

The Navy has determined that manning is the single largest cost component in naval operations, and has mandated that crew size on future ships be reduced dramatically. NSWCCD believes opportunities exist to employ automation technology to replace sailorsin what is perhaps the Navy's most manpower-intensive process -- the handling of cargo from pierside warehouses through a series of supply ships t ...

There is an emerging need within military electronics for protection of electronics from the adverse effects of high power electromagnetic radiation. The Department of Defense has a requirement to ensure survivability of important military C3 and weaponssystems against the effects of electromagnetic weapons threats. What is needed is an electromagnetic hardening technology that is lightweight ye ...
