From the results of experiments, it is well known that the detached shock wave ahead of the nose surface is a nearly uniform normal shock with a constant detachment distance. Therefore, the subsonic flow field between the shock wave and the nose surface can be approximated by the incompressible potential flow theory. The detachment distance is represented in semi-empirical form, and the results show that the mean outgoing velocity between the shock wave and the nose surface at the edge of the flat nose has a constant value of 0.40a, independent of the free stream Mach number. With a boundary condition based on this constant velocity, the surface pressure distribution around the stagnation point on an arbitrary shape flat nosed body can be calculated, and the results show good agreement with the experimental value. This estimation can be extended to a nose with a small curvature, also., 資料番号: NALTR0747000, レポート番号: NAL TR-747}, title = {超音速流中の平頭物体に対する近似解析}, year = {1982} }
