失速迎角指飞机达到最大升力系数时的迎角。
对比结果表明：柔性翼相比于对应的刚性翼，失速迎角较大；
Experiment results indicate that the flexible wing has a larger angle of stall and a greater maximum lift coefficient than the fixed wing.
铰链力矩系数在失速迎角达到之前就发生突变，可以更安全地用来预测失速的发生。
The hinge moment coefficient breaks before the stall of Angle of attack and can be used for predicting stall more safely.
在失速迎角后，尖顶襟翼对升力系数的提高有明显的效果，而对阻力系数的影响不大；
The apex flap deployment had a promising effect on the lift after stalling angle, but it had little effect on the drag.
