Abstract
Unsymmetrical gas flows around a carrying airfoil, with velocities close to sonic at infinity, are discussed. In a region situated a certain distance from the profile, an asymptotic solution of the flow problem is constructed. A detailed analysis is made of the dependence of the terms of the asymptotic sequences of the parameters characterizing the transverse and longitudinal dimensions of the body. The law of change in the lifting force as a function of the difference 1 − M∞, which is assumed to be small, is established. The connection between the theoretical results and experimental data is discussed in detail.
