摘　　要：复合式高速直升机是直升机的热点发展方向之一,为此开展了一款小型(100 kg级)复合式高速直升机的设计研究。首先,提出了设计要求并给出合适的总体参数。然后,进行了气动布局设计并绘制三维模型,对该构型存在的旋翼/机翼/螺旋桨气动力部件干扰使用动量源方法进行了初步分析,得到了气动干扰特性及机身气动部件随不同速度前飞时的升阻力特性。最后,基于常规直升机的飞行性能计算方法,提出了复合式高速直升机飞行假设及该构型飞行性能的计算方法,并对飞行性能进行了分析计算,完成了100 kg级复合式高速直升机总体方案设计。研究成果可为今后该构型飞行器的设计研究提供一定的借鉴。As composite high-speed helicopter is one of the hot developing directions of helicopter, we conducted the design and research of a small compound high-speed helicopter(100 kg). Firstly, this paper presented the design requirements and the appropriate population parameter. Then, the aerodynamic layout was designed and the 3 D model was drawn, a preliminary analysis of the rotor/wing/propeller aerodynamic component disturbances of this configuration was carried out using the momentum source method, obtained the aerodynamic interference characteristics and the lift drag characteristics of the aerodynamic components of the fuselage when flying forward with different speeds. Finally, based on the flight performance calculation method of conventional helicopter, the flight assumptions of the composite high-speed helicopter and the calculation method of the flight performance for this configuration were proposed, the flight performance was analyzed and calculated, and the overall scheme design of the 100 kg composite high speed helicopter was completed. The results of the research can provide some reference for future design research of this configuration.
