Advanced Chemistry and Radiation Modules for Wake and Reentry Flows

The outcome of the proposed SBIR program will be the development of an innovative scientific testbed code suite for reentry vehicle signatures. The testbed will model all key physical hypersonic flow effects to a high degree of fidelity and will be validated against field data. It is intended that the scientific testbed code could be used as a benchmark to test lower-fidelity models, or could be used as an inexpensive substitute for laboratory or field tests. Chemistry, radiation, ablation, plasma effects, and other modules within this testbed code suite will then be interfaced to existing MDA simulation tools to create an engineering and applications code suite. By the end of Phase II, the engineering code suite will provide a validated, practical, and accurate end-to-end infrared and radar cross section simulation capability for MDA signature applications.
