Abstract
A radiative heating calculation method for reentry vehicles into the earth's atmosphere was studied, the four band spectra model in the QRAD for high temperature air was used. The heat dissipation due to radiation and the nonequilibrium effect were considered. The Newton pressure distribution was used for the radiative heating distribution calculation of reentry vehicles bottom faces. The results indicate that the method developed in the paper can predict the radiative heating of reentry vehicles into the earth's atmosphere.
