Abstract
Mathematical simulation of the forced vibrations of a surface segment on one side of an aerofoil on the shock wave formed in the transonic flow around it has been performed. The influence of the vibrations of this segment in a wide frequency range on the quantitative and qualitative characteristics of the wave drag and lift of the aerofoil were investigated for the case of maximum amplitude of oscillations of the velocity of movement of the vibrating segment of the aerofoil, close to the velocity of the incident flow. It is shown that an additional lifting force arises in this case.
