Description

Atmospheric reentry vehicles produce large amounts of heat and plasma due to the high Mach number. This process is primarily driven by the non-equilibrium high-temperature chemistry that is present in the bow-shock and the gas surface interactions. Due to the high temperature, in excess of 20,000K, it is difficult to experimentally derive meaningful values. A combination of theory and flight/ground test data is used to validate these models. For this reason, it is necessary to develop physics based models for all of the drivers in hypersonic flight and use the combined effects to produce a high fidelity simulation of the flight. This allows for optimization and validation of the chemical models. This effort supports development of all the constituent physics and chemistry for a high fidelity hypersonic flight solution.
