During hypersonic reentry, the flow around reentry vehicles is ionized resulting in electro-optical and infrared emissions, detectable radar cross-sections, and attenuation of signals transmitted through the plasma. Modeling these flows requires both expertise and substantial user time. The Phase II program will address these issues by developing the Reentry Vehicle and Wake Analysis Tool that wil ...

Our proposal specifically addresses the stated requirements of the solicitation; we will develop and deploy tools, for improving optimistic modeling techniques. The proposed EDAptive PROMOTE solution, focuses on diagnosing, fixing, and reducing rollback and repeatability errors in optimistic models and simulations. In addition, PROMOTE aids in the conversion and embedding of non-optimistic models ...

Phase I proposes to demonstrate an easy-to-operate, inexpensive room temperature neutron detector based on boron-doped diamond. The detector would produce an immediate signal related to low-level neutron irradiation. The concept exploits the high neutron absorption cross section of B-10, which results in excellent sensitivity. The charge carriers generated in the diamond by a neutron absorption ev ...

Essential Research, Inc. proposes to build a thermophotovoltaic (TPV) electric generator using a solar concentrator heat source with thermal storage capability, a selective emitter, and a photovoltaic cell. The operation point of the heat source and selective emitter will be approximately 1700K. The moderate operating temperature was chosen to provide a system energy conversion efficiency of great ...

Under this STTR Imaging Systems Technology (IST) will apply novel Plasma-shell technology and expertise with gas plasma systems to shield and protect BMDS Radar. Plasma-shells are tiny hollow gas encapsulating shells. When energy is applied across the shell, the gas inside ionizes into a plasma. Theory of plasma-electromagnetic (EM) field interaction shows that, under appropriate conditions, pl ...

Mercury Cadmium Telluride (MCT) has been described as one of the most technologically significant semiconductor materials and is the most widely used material for long wave infrared (LWIR) imaging. The current challenge is to produce MCT over large focal plane array size at low cost and high reliability without compromising sensitivity or noise performance. MCT on silicon substrates is highly attr ...

Today"s Ballistic Missile Defense networks consist of many different types of sensors and platforms, and given the expanded focus of MDA on theater and regional missile defense where multiple"raids"can be launched from different sites toward numerous targets, it is crucial that they can be dynamically tasked and deployed effectively in real-time to realize their full potential in achieving overall ...

This Phase I Small Business Innovative Research Program will develop and demonstrate the technology to produce large-scale, high temperature, lightweight composite missile structures for transition to a fielded weapons system where weight minimization and resistance to high temperature exposure is critical. Performance Polymer Solutions Inc."s composite system has the ability to survive in extrem ...

At hypersonic flow conditions, the flow field around reentry vehicles is ionized, resulting in electro-optical emissions, detectable radar cross-sections, and attenuation of signals transmitted through the plasma. Ablative heat shields may further increase the levels of electrons in the plasma around the hardbody and in the wake. We propose to extend an existing high-fidelity computational fluid d ...

We propose to define a dynamically reconfigurable photonics-based system to efficiently collect, down-convert, distribute, and selectively combine the return signals from multiple array elements to a set of digital processors. Electronic signals from the array elements will modulate optical carrier signals. With an appropriate choice of optical carrier signal and photonic architecture, the signals ...
