Abstract

Statistical BGK simulations coupled with the material response solution were performed to estimate the micro-crack growth in an arcjet AVCOAT coated specimen representing the Crew Exploration Vehicle thermal protection system. The after shock inlet boundary conditions for the BGK studies were obtained from a CFD (DPLR1) solution of the arcjet flow. The solution of the arcjet case is followed by a 81 km CEV flow-material response study which represents a point along a CEV re-entry trajectory. Rarefied flow conditions at 81 km prompted using the baseline DSMC technique to solve the shock wave layer flow providing data for the inlet boundary conditions for the local crack-material response studies. The results draw a preliminary conclusion regarding the effectiveness of the AVCOAT protective mechanisms against the growth of the micro cracks during the Earth atmosphere re-entry of the vehicle.
