Abstract

The article presents basic dependencies applied in engineering practice to compute convective and radiative heat flows at the blunting point of the descent module. The analysis of heat flux densities was performed, which results allowed selecting materials of the heat-protective coating. The authors suggested the new structural scheme of the heat-protective coating, namely the paneled one. Transition to the paneled type will allow significant simplification of the variety of the heat tests, as well as facilitation of the descent module assembly and servicing of its systems.

Keywords:

heat protective coating, descent module, heat testis, heat flows, supersonic speed
