摘要

The authors propose here the three-dimensional representations of the inviscid drag coefficient C_d~((i)) (as function of the angle of attack α and of the Mach number M_∞ of the incoming flow) and of the inviscid polar of the wedged delta wing in supersonic flow. A continuous behaviour of the class C_1 of the both surfaces along the sonic lines which separate the domains in which the delta wing has subsonic and, respectively, supersonic leading edges is to be observed, even the solutions of the boundary value problems of the axial disturbance velocities of the thin and thick-symmetrical delta wing components are, in these both regions, very different.
