Abstract
A conjugate problem on the nonstationary heat exchange in the supersonic gas flow past a conic body with a nose blunted over a sphere at a zero angle of attack was solved for the case where the stagnation flow temperature is as high as 2500 K. The possibility of control of the temperature regime of such a body in the case where a laminar flow is realized in the boundary layer on its surface was investigated. The results of calculations were generalized in the form of criterion dependences allowing one to determined the maximum temperature on the surface of the body with a good accuracy, including for a nonstationary flow over it, which makes it possible to estimate the ranges of thermophysical and geometric parameters of the body in which the temperature of its surface can be decreased to a required level.
