摘　　要：过渡模式是倾转旋翼机全过程自主飞行的关键阶段,亦是最容易发生安全事故的阶段。过渡轨迹是飞行器过渡模式控制律和制导律设计的基础,以某型无人倾转旋翼机为研究对象,分析其气动特性,并根据过渡阶段的升力来源,将整个过渡阶段进行细化;再根据各个阶段的约束条件确定其倾转过渡走廊;依据飞行器的飞行过程以及走廊确定飞行器的过渡轨迹,并通过仿真验证其合理性。The conversion mode is the key stage of the autonomous flight of the unmanned tilt-rotor.It is,however,the most dangerous stage during the entire flight.The conversion trajectory is the basis of the design of the control law and guidance law of the unmanned tilt-rotor aircraft.The paper therefore takes an unmanned tilt-rotor as the research object.The aerodynamic characteristics of the target drone are analyzed and the entire transition phase is segmented according to the source of lift.Then the constraints in the flight process are determined according to the flight characteristics of each phase,so as to determine the conversion corridor of the target drone.The flight characteristics of the aircraft and the conversion corridor are applied to determine the conversion trajectory.The simulation result verifies the rationality of the trajectory design.
