IN this report, the difference of the pressure coefficient and the drag coefficient between ideal gas and real gas was investigated on flare and boattasls at supersonic speed. For this porpose, the characteristics method was employed. And the difference of the drag coefficient, and the pressure coefficient between ideal gas and real gas was investigated. Also, the difference of the drag coefficient between real gas and the boundary layer was investigated. It has been found that in some region of high density and low temperature, the drag coefficient of real gas is comparable to that of the boundary layer.
