摘要
研究前掠翼根部流动分离控制问题,提出了两种改善翼根气流分离的流动控制方法。CFD研究表明,通过加近距耦合鸭翼或大后掠边条,能够明显改善前掠翼根部流动分离状况,提高前掠翼的大迎角气动性能。
A research on the control of separated flow at the root for forward swept wing is made of, and two measures are presented to improve the control of separated flow at the root. The CFD results show that close canard wing or large swept back strakes, can improved the forward swept wing＇ s flow separated obviously, and also can improved the aerodynamic characteristics of the forward swept wing at high angle of attack.
