北京理工大学珠海学院 2020 届本科生毕业设计（论文） 倾转旋翼无人机飞行状态切换过程的研究切换过程的研究摘 要倾转旋翼无人机是一种可以不受地形环境影响而垂直起飞降落、集固定翼飞机和直升机的有点于一身的新类型飞行器，其突出的两个优点是：能高速巡航；能长距离运输。本文针对目前现有的倾转旋翼无人机的飞行状态模式，分析其现阶段飞行状态的特点、以及目前国内外对飞行状态切换这方面存在的不足，通过研究倾转旋翼机的外形结构设计、基础的飞行控制建模、翼型的流线型设计、平衡与稳定性和新型气动布局等方面来改善倾转旋翼无人机飞行状态存在的问题，使其在外形结构、起飞降落、续航时间方面具有一定的优势，从而探究此类无人机飞行状态切换（垂直起降转为平飞的过程）所需要达到的条件、存在的限制、实现的困难问题，在航拍测绘、公共安全、环境保护、智慧城市、影视传媒等方面的应用更加广泛，并得出结论和对这类无人机的未来展望。关键词：倾转旋翼无人机 飞行状态切换 外形设计 动力系统 应用场景。I北京理工大学珠海学院 2020 届本科生毕业设计（论文）A Study on the Switching Process of Flight Statusfor Tilt Rotor UAVABSTRACTThe Tilt Rotor UAV is a new type of aircraft that can take off and land vertically without being affected by the terrain environment. It is a new type of aircraft that integrates fixed-wing aircraft and helicopters. Its two outstanding advantages are: high-speed cruising; long-distance transport. This paper analyzes the characteristics of the current state of flight of the current tilt rotor UAV, analyzes the characteristics of the current flight state, and the current deficiencies in the switching of flight status at home and abroad. By studying the shape and structure design of the tilt rotor aircraft , Basic flight control modeling, airfoil streamlined design, balance and stability, and new aerodynamic layout to improve the existing problems of the tilt rotor UAV flight status, so that it has the shape structure, takeoff and landing, endurance time ...
