摘　　要：论述和建立了旋转机翼飞机在旋翼飞行模式下,低速前飞时飞机的飞行动力学模型。根据飞行特点,建立了低速前飞情形下的简化飞行动力学模型。针对旋转机翼飞机的旋翼特点,在建立模型时,考虑了旋翼旋转引起的下洗流对机体的影响;研究了旋转机翼飞机在低速前飞时的配平,提出了一种简化的计算方法,并以某样机为例,建立模型并配平,验证了模型的正确性;最后,研究了重心位置对前飞时纵向操纵和俯仰姿态的影响。In this paper,a new dynamics model is discussed and established for a rotor-wing plane in horizontal flight at low speed.The rotor-wing plane has the special characteristics of large diameter,etc..In order to establish the model of the rotor-wing plane accurately,the dynamic pressure changes of the fuselage caused by the downwash of rotors must be considered.A new rotor-wing plane is taken as an example to carry out the trim calculations at low flight speed.At last,the manipulation and pitch attitude at different center of gravity in horizontal forward flight is studied.
