    • An improved method of operating rotorcraft capable of achieving high speeds such that stability is maintained as the craft speed exceeds 0.75 times the rotor tip speed. These high speeds are achieved by varying collective pitch, including to negative values, to maintain acceptable levels of flapping at high aircraft forward speeds and low rotor rotation rates, or adjusting or maintaining the rotor rotation rate by automatically controlling the tilt of the rotor disk relative to the airstream or aircraft, or a combination of these techniques. More specifically, by utilizing these techniques the forward aircraft speeds can be high enough, and the rotor rotation rates low enough, that an advance ratio, Mu, greater than 0.75 can be achieved while maintaining rotor stability.
    • 一种改进的能够实现高速度的旋翼航空器的方法,使得当飞行速度超过转子尖端速度的0.75倍时,维持稳定性。 这些高速度通过改变总体间距(包括负值)来实现,以在高飞机前进速度和低转子旋转速度下保持可接受的振荡水平,或通过自动控制转子盘相对的倾斜来调节或维持转子旋转速率 气流或飞机,或这些技术的组合。 更具体地说,通过利用这些技术,前进飞机的速度可以足够高,并且转子旋转速度足够低,可以在保持转子稳定性的同时实现大于0.75的提前比率Mu。
