摘要
基于动量源方法,建立了旋转机翼飞机的旋翼/机身组合流场的数值模拟方法。首先通过Caradon-na-Tung旋翼算例计算,验证了本方法的有效性;然后采用该方法对某旋转机翼飞机的悬停及低速前飞状态下的旋翼/机身干扰流场特性进行了详细的计算与分析。结果表明,该方法能够用于计算旋翼与机身的干扰流场,为旋转机翼飞机的设计提供了参考。
In this paper,a numerical simulation method based upon the momentum source method is established to predict the interactive flow field of the rotor wing plane.The Caradonna-Tung rotor case is computed first to validate the method.Then the analysis on the rotor/fuselage interactive flow field for the rotor wing plane in hover and forward flight is given using the present method.The results indicate that the method can be used to compute the interactive flow field and it can give useful suggestions when design a rotor wing plane.
