Aerodynamic coefficients of a reentry bodyin hypersonic flowfiled are calculated by using a three-dimensional flow solver. The high temperature real gas effects, thermal excitations and chemical reactions of air, are accounted for in the calculation. The reasonable agreement between the calculated aerodynamic coefficients and the Apollo AS-202 flight date are obtained. The effects of thermochemical nonequilibrium on the aerodynamic predictions are shown to be non-negligible.
