FIELD: aviation.
SUBSTANCE: method for eliminating shock wave oscillations on a civil aircraft wing at transonic flight speeds by blowing an air jet tangentially to the upper surface of the wing. Blowing is performed into the separation area behind the shock wave with a jet impulse coefficient of 0.0005 from a slotted nozzle located at a distance of 8% of the chord length from the position of the shock wave.
EFFECT: invention is aimed at reducing energy costs while eliminating shock wave oscillations in the transonic flight mode due to the minimum blowing intensity.
