摘要

The flow of a gas over a conic body, having a nose blunted over a sphere, with a supersonic velocity at different angles of attack was considered. The possibility of control of the temperature regime of such a body in the case of three-dimensional gas flow over it was investigated. The dependence of the temperature of the surface of the indicated body on the material of which it is made, the angle of attack of the body, and other constitutive parameters of the problem on conjugate nonstationary heat exchange between the body and the gas fl ow over it was determined for standard conditions of an aerodynamic experiment. Results of numerical solution of this problem for different angles of attack of the body were processed in the criteria form. The dependences obtained allow one to estimate the degree of decrease in the maximum temperature at the surface of a blunt-nosed conic body depending on the thermophysical parameters of the material of which this surface is made, including in the case of nonstationary gas fl ow over it. It is shown that a uniform heating of the peripheral part of such a body and a marked decrease in the temperature of its windward part at large angles of attack can be provided with the use of highly heat-conducting materials for these parts of the body.
