| 摘 要： | 本文用简化的自由涡模型研究旋翼近场尾涡系在机身影响下的畸变及其产生的诱导速度交化。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。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。

| Abstract: | The effect of helicopter fuselage on its rotor is studied using a simplified free-wake model. 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. 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. |
