摘　　要：多桨倾转机翼飞行器飞行模式多且操控复杂,尤其是倾转过渡模式,气动干扰复杂,操纵冗余。从理论上分析不同机翼倾转过渡方式下(同步倾转和异步倾转)的气动与操纵特性难度大。为了研究多桨倾转机翼飞行器不同机翼倾转过渡方式的气动与操纵特性,对某小型多桨倾转机翼无人机开展了整机机翼同步和异步倾转过渡方式下不同机翼倾角、不同速度、不同油门、不同舵面角度下的吹风测力试验。根据试验数据分析了整机不同机翼倾转过渡方式下的俯仰操纵特性,为多桨倾转机翼构型飞行器倾转过渡模式操纵策略研究提供参考。It is very difficult to analysis the aerodynamics and control characteristics theoretically with different wing tilt transition modes(synchronous tilting and asynchronous tilting) for distributed propulsion VTOL tilt-wing aircraft,because of multi-flight modes,complexity of control,especially complexity of aerodynamics interactions and redundancy of control surfaces for the tilting flight mode.In order to investigate the aerodynamics and control characteristics with different wing tilt transition modes,a small unmanned distributed propulsion VTOL tilt-wing aircraft was tested in wind tunnel with different wing tilt angles,speeds,throttles and control surface angles for synchronous and asynchronous tilting transition modes of the wing.According to the experimental data,pitch control characteristics of the aircraft with different wing tilt transition modes were analyzed,which provided some references for research on manipulation strategy for the tilting flight mode of distributed propulsion VTOL tilt-wing aircraft.
