Based on the theory of structural stability, this paper investigates the transition of the flows over slenders at Angle of attack from symmetric state to the asymmetric state.

从结构稳定性的思路出发，研究了圆锥体有攻角绕流对称流态到非对称流态的转变。

Therefore, it is further proved that local failure theory is correct and weak structural plane will control the stability of slope.

从而进一步证明了局部破坏理论的正确性和边坡软弱结构面是控制边坡稳定的关键因素。

The experimental results verify that the feasible theory can be used to investigate the effects of structural parameters of hingeless rotor on aeroelastic stability.

试验证明该理论可行并能用于研究无铰旋翼结构参数对桨叶气弹稳定性的影响，也能用于直升机旋翼的型号设计。
