新型双轴倾转旋翼飞行器总体设计与控制分析OA

The tilt-rotor aircraft combines the capabilities of vertical takeoff and landing with efficient high-speed cruising,making it suitable for short-haul low-altitude transportation.However,the overall design of existing tilt-rotor aircraft does not consider the safety of forced landings during short-haul transport,and both the overall layout and control strategies need optimization.This paper presents the design of a novel dual-axis tilt-rotor aircraft.By comprehensively considering the integration of rotor blades and multiple flight modes,the overall layout of the air-craft is optimized.This enables the aircraft to perform a forced landing in fixed-wing mode on a single lane of a ground roadway with minimal impact on ground traffic,while still carrying a sufficiently large payload.Furthermore,a six-degree-of-freedom dynamic and kinematic model of the aircraft is established.A control analysis of the six-degree-of-freedom flight under the new layout of the aircraft is conducted,and a new control strategy is proposed.The feasibility of the new control strategy is verified through dynamic simulation.The results show that the proposed aircraft,with a properly optimized configuration,exhibits the potential to enhance aerodynamic efficiency,leverage the advantages of rotor-wing integration,and demonstrates favorable control characteristics.The aircraft design scheme can provide a reference for the development of tilt-rotor aircraft designed for low-altitude operations.
