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.

使用切向射流对机翼翼型进行跨音速自助控制的实验研究

摘要 介绍了使用切向射流吹到超临界机翼翼型上表面来抑制激波引起的流动分离和消除跨音速流态中的跨音速抖振的实验研究结果。实验研究在中央空气流体动力学研究所 (TsAGI) 的 T-112 风洞中进行。分析和比较了基线配置和喷射吹气的结果。他们表明切向射流吹气抑制了激波引起的流动分离，增加了升力，并延迟了抖振的开始。
