Abstract

A new generic thermal protection system material response model was developed and applied to study the AVCOAT generated blowing rates at different altitudes along a typical Crew Exploration Vehicle (CEV) trajectory. The Direct Simulation Monte Carlo (DSMC) flow simulations were performed to estimate the heat flux into AVCOAT coated heat shield. To demonstrate the model, the pyrolysis gases generation rate was computed at different times along a CEV trajectory. The model blowing rates were compared with available data as well as with PICA.
