Abstract
The results of an experimental investigation of the suppression of shock-induced flow separation and the elimination of transonic buffet in transonic flow regimes using tangential jet blowing onto the upper surface of a supercritical wing airfoil are presented. The experimental investigation is performed in the T-112 wind tunnel of the Central Aerohydrodynamic Institute (TsAGI). The results obtained for the baseline configuration and those with jet blowing are analyzed and compared. They showed that the tangential jet blowing suppresses the shock-induced flow separation, increases the lift, and delays the onset of the buffet.
