The results show that the rotor near-wake is distorted because of the flow field of the fuselage, resulting in large variation on the induced velocity distribution at the rotor plane.
在机身影响下，旋翼近场尾涡形状发生畸变，从而改变桨盘处的诱导速度分布。
In particular, expressions of flapping coefficients are derived, including the effect of variable induced velocity distribution but in terms of blade parameters and flight parameters only.
特别是在挥舞系数的表达式中，考虑了诱导速度的变化，但直接与桨叶参数和飞行参数有联系。
The variation of the induced velocity distribution at the rotor plane caused by the fuselage through distorting the rotor near-wake is much larger than that induced by the fuselage directly.
尾涡畸变引起的诱导速度变化比机身直接在桨盘处诱导速度大得多。
