Abstract

The problem of protection of the construction of a recoverable space vehicle from intensive exposure joint convective and radiant thermal streams becomes actual by development of reusable space vehicles of new generation. The decision of this problem will demand statement scale theoretical and experimental researches directed on studying of process of interaction joint convective and radiant thermal streams with a surface of heat-protective coating of the spacecraft. Thus development of the new heat-protective materials possessing higher heat-protective properties at their minimal density (ρ ≤ 103 kg / m3) is required. In the given work results of reproduction of the convective-radiant heat exchange accompanying an entrance of space vehicles in atmospheres of planets with the second space velocity are resulted. Such researches are carried out on the faculty « Aerospace heating engineers » of the Moscow Aviation Institute (the State Technical University) at support of the Russian Federal Property Fund, the project №09-08-00169-a.

Keywords:

the convective-radiant heat exchange, heat-protective coating, the atmosphere of planet, convective and radiant thermal streams, the problem of protection.
