| Abstract: | 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. |
