Technology applications beyond NASA include Theater and National Missile Defense vehicles performing exo-atmospheric missile intercepts, and missile warhead re-entry applications. The computational tool will also be relevant to the joint DOD/NASA effort called the National Aerospace Initiative (NAI) that involves, among other things, the development of air-breathing hypersonic vehicles. The module will have wide appeal to rocket engine manufacturers (e.g., ATK, Pratt & Whitney, and Aerojet) and to universities developing rocket engine technology (e.g. Purdue, Penn State, and University of Alabama in Huntsville). OEMs will also find the tool useful in exploring and designing newer and more robust ablative TPS materials and heat shield systems. The models developed in this SBIR project can also be ported to commercial CFD software such as CFD-ACE+ and CFD-FASTRAN (owned by ESI Inc. Huntsville). Future NASA missions will be more demanding and will require better performing ablative TPS than currently available. The proposed SBIR project will result in a computational tool with unique and accurate predictive capabilities for non-equilibrium re-entry flows with ablation cooling. The tool will find direct application in numerous NASA technology development programs under the Project Constellation, the New Millennium Program, and the In-Space Propulsion Technology Program. The tool can also be used as a design tool for the development of new generation re-entry vehicles (such as the Crew Exploration Vehicle, Mars Aerocapture and Mars Sample Return spacecraft) and components of future hypersonic vehicles. The various models comprising the tool will be implemented in an extensible and modular framework that can be ported to other NASA codes with relative ease.
