Abstract : An exact method has been developed for determining the streamline geometry and equivalent radius (the scale factor for the normal coordinate in a streamwise coordinate system) over a flat delta wing with cylindrical leading edge at angles of attack. This method requires a knowledge of the surface inviscid pressure distribution, either theoretical or experimental. With the aid of the present method, three-dimensional hypersonic heat transfer can be simply calculated through the axisymmetric analogue. Results are presented for flat delta wings traveling at hypersonic speeds and at various angles of attack.
