| Abstract: | The asymmetric aerodynamic characteristics of aircraft at high angle of attack are investigated.Adopting a converter turbulence technique and through the experimental study of slender cylinder and wing-body combination models,the effect of turbulence and manual micro perturbation on the asymmetric flow around them at high angle of attack is analysed.The obtained test results demonstrate the turbulence and manual micro perturbation can indeed affect the flow asymmetry occurring on the high-alpha aircraft models. |
