The innovation for this Phase I program is the extension of the new Rocket Plume Flowfield Model (RPFM) to analyze Reentry Vehicle (RV) body flows. The Phase I effort provides the foundation for a highly optimized, fast-running Reentry Vehicle Flowfield Model (RVFM) for analysis of thermal protection systems (TPS). Many of the key features are already in place to expedite RV flow solutions (GUI, N ...

Recent work in high speed reacting flows has identified three areas in which model improvements are needed. (1) Multi-element grid adaptation for fuel injection problems - h-refinement (cell splitting) procedures being utilized in our grid adaptation tool, CRISPr, produce large meshes after several levels of refinement. Point redistribution (r-refinement) techniques based on moving mesh concepts c ...

The design of turbomachinery components is a complex process requiring many steps and hundreds of minute decisions in an iterative process. The design proceeds from engine cycle performance and meanline design through 3D viscous flow calculations (CFD) and finite element structural analysis (FEA). Design studies may traverse this process many times, with routine tasks performed by engineers in a ...

Superconducting coils are capable of storing considerable amounts of energy. Should a coil quench, due to overheating or exceeding the critical field or current, the stored energy in the coil must be dissipated safely - without endangering personnel or damaging the coil or control systems. In any superconducting coil design, it is essential to design and build the system such that limits of the ...

We propose to develop an earth penetrator with improved shape for trajectory stability during high-speed penetration. Several promising penetrator shaping concepts have been identified in Phase I. Through further analysis, one or two of these will be selected for further development. Penetrator designs will be formulated and optimized, then tested through gun firings of scale-model penetrators int ...

The project focus is the development of a ground target tracking algorithm to support the JSTARS radar operating in the GMTI mode. Multiple hypothesis tracking (MHT) algorithms maintain alternative data associations to represent report-to-track association ambiguities. In Phase 1 we developed a prototype MHT algorithm not requiring the Bayes’ posterior distribution for the target state to be G ...

The design of Unmanned Aerial Vehicles (UAV’s) is a complex process of creating a reliable system of reasonable cost that can survive in hostile environments. Although UAV’s have unique aspects to them, similar goals can be found in almost any complex, competitive product. One aspect of the design of these systems that tends to be both difficult and poorly supported with available computer ...

Dynamic Sensors, Incorporated (DSI) proposes a superior approach to Algorithms for Hyper-spectral Image Processing for the problem of spatial-spectral-temporal measurements of transient phenomena. DSI will demonstrate a Machine Intelligent Processor (MIP) software tool for rapid identification of dynamic battlefield events. MIP is an image analysis approach that is based on a neurobiological mod ...

75272B Transmission Electron Microscopy is a technique that allows materials to be analyzed to the nanometer and sub-nanometer scales. The next level of materials analysis will require the ability to perform dynamic experimentation within the microscope, which would require specialized specimen holding technology to perform the desired experiments. This project addresses the treatment of a spec ...

The main objective of this program is to develop a new class of high performance hard magnetic materials that will maintain an energy product of 30 MGOe or greater at temperatures up to 450 °C. These novel magnetic materials are greatly needed for the "more electric" airplanes and space vehicle applications where a high operating temperature is a strict requirement. The approaches to be used for ...
