Flow structure and aerodynamic characteristics of a double-wedged airfoil at transonic velocities, as well as the peculiarities of transition from subsonic to supersonic flow regime, are discussed in this paper. The interest in this airfoil is caused by the fact that it is considered to be an optimal airfoil from the viewpoint of wave drag within the framework of ideal gas theory. Its aerodynamics was actively investigated both theoretically and experimentally in 1950s–1960s.

The Rayleigh problem for a compressible fluid is considered in the present paper. The purpose of this work is to study the effect of compressibility of a medium in motion on the flow structure and aerodynamic parameters of the streamlined surface.
