High temperature Vol. 59, № 1. P. 99-105Abstract: The conjugate problem of nonstationary heat transfer in a supersonic flow over a spherically blunted cone at a high Mach number (M∞=9,9) is considered. Under these conditions, the maximum temperatures of the streamlined shell can be as high as the material fracture temperature. Hence, it is essential to assess the potential methods of their reduction. The generalized criterion dependences derived from the numerical solution of the nonstationary conjugate problem make it possible to estimate the necessary decrease in the maximum temperature of the body surface via the selection of the proper geometry and thermophysical characteristics of the materials of the spherical and conical regions of the body.
