The sonic-wedge characteristics method has been used to obtain the shock shapes and surface pressure distributions on several blunt two-dimensional shapes in a, hypersonic stream for several values of the ratio of specific heats.- These shapes include the blunt slab at angle of attack and power profiles of the form yb = axm, where 0 < m < 1, yb and x are coordinates of the body surface, and a is a constant.nThese numerical results have been compared with the results of blast-wave theory, and methods of predicting the pressure distributions and shock shapes are proposed in each case.nThe effects of a free-stream conical-flow gradient on the pressure distribution on a blunt slab in hypersonic flow were investigated by the sonic-wedge characteristics method and were found to be sizable in many cases. Procedures which are satisfactory for reducing pressure data obtained in conical flows with small gradients are presented.
