ABSTRACT
The different characteristics of hypersonic flow (v ~ 20-60 km/sec, atmosphere pressure 10"1-10 KPa) around a space probe in a helium-hydrogen atmosphere simulating the upper layers of Jupiter and other giant planets of the Solar system has been intensively studied recently [178-188]. The main feature of the present work is a consistent account of the main physical processes of interaction in a multicomponent chemically reacting plasma of a shock layer between a separated shock wave and a spherical probe graphite surface in the estimation of convective and radiant heat currents at a probe stagnation point. The processes mentioned are: the injection of graphite thermal protection coating into a shock layer under the action of powerful heat fluxes, radiant and convective heat transfer through a shock layer to the surface of probes, the multicomponent character of the diffusive mixing of plasma components in a shock layer.
