惯性颤振临界速度 critical flutter speed
The winglet addition decreases the flutter speed more than 10%,and may change the flutter mode for subsonic flow case. The C-type wingtip generates a reduction of flutter speed up to 19%,but has a minor impact on the flutter frequency.
翼梢小翼使得颤振速度下降超过10%,并可改变亚音速时机翼的颤振模式;而C型翼梢能使颤振速度降低19%,对颤振频率的影响则较小。
