 note = {A numerical calculation of the supersonic flow of a perfect gas over conical flares, cone-cylindar and conical boattail at a small angle of attack was performed. The Allen. E. PUCKETT method was found to be useful for predicting the flow field about conical Flares with slope abnormalities. The relationship of the normal force distribution between linearized theory and the present method is shown. The normal force distribution calculated by the present method was found to be smaller than that of linearized theory as a whole. Linearized theory estimates the density of gas to be thicker than that of present theory. The present method was simplified by eliminating the density terms. According to the linearized theory, the normal force coefficient is determined by the area ratio of a flare or boattail and is constant along the flare or boattail surface. However, the present method shows that the normal force coefficient decreased downstream, since the density of a gas decreases as it flows downstream. Even if the mach number varies, linearized theory shows that normal force is constant. But present theory shows that normal force decreases as mach number increases for flare and boattails and exact analytical solution is obtained for supersonic flow along with a slighly inclined circular cone. The governing equations are simplified by eliminating the desity terms, and the after-body of a cone cylinder was calculated by the present method. In the present paper, we also investigate overexpanded sonic jets through axisymetric conical nozzles and investigated the effect of pressure and mach number of super sonic jets., 資料番号: NALTR0949000, レポート番号: NAL TR-949},
