摘　　要：倾转旋翼飞机翼尖有一台可旋转的发动机带动两旋翼,实现飞机垂直起降和水平飞行,倾转部分是其区别于普通飞机的独特结构。通过对比研究,设计了一种可以实现旋翼旋转的结构,以及发动机布置等相关结构,该结构使用三只行星齿轮,满足载荷均布性,使结构具备实用性、稳定性和可靠性,设计可以模块化生产。采用定量研究,对相关结构在飞机几种主要飞行状态时的受力情况进行了简单的力学分析,对转轴强度、转轴直径、旋转用电机、机翼末端的强度要求等进行初步的理论计算。研究发现,倾旋转部分和机体部分的重心相对于机翼转轴的位置,对机翼的扭矩大小有重大影响。本研究为此类飞机的研发提供一些基础的设计及理论数值计算。The tilt rotor aircraft has a rotatable engine on the tip of every wing.It makes the aircraft to take off and land vertically and fly horizontally.The rotation structure is the unique structure that distinguishes it from ordinary aircraft.No public information has been found on the rotation structure of large tilt-rotor aircraft.By comparative re-search,a kind of structure which can make rotor rotation and some related structures such as engine arrangement were designed.Three-planet gear structure was used to satisfy the load distribution.The design can make the structure prac-tical,stable and reliable.It can be modular production.Using quantitative analysis method,a simple mechanical a-nalysis was carried out on the stress of the relevant structures in several main flight states of the aircraft,and prelimina-ry theoretical calculations were conducted on shaft strength,shaft diameter,rotating motor,and the strength require-ments of wing ends.Research has found that the position of the center of gravity of the tilting and rotating parts and the body parts relative to the wing axis has a significant impact on the torque of the wing.The research provides some basic design and theoretical numerical calculations for the development of such aircraft.Research has found that the position of the center of gravity of the body parts relative to the wing axis has a significant impact on the torque of the wing.The research provides the basic design and theoretical numerical calculations for the development of such aircraft.
