Aerothermodynamics of the Federation crew module at high-altitude reentry

Using the GPU calculation, the integral aerothermodynamics of the Federation crew module in a wide range of altitudes, Mach numbers and the angle of attack were obtained by the Direct Simulation Monte Carlo (DSMC) method. A technique for calculating the radiative heat flux onto the surface of the capsule has been developed. With the help of the created technique and data of the DSMC simulation of the structure of an ionized shock layer, estimates of the spectral and total radiative flux to the surface were made.
