The tilting rotorcraft comprises a nacelle and a winglet, the winglet is rotatably arranged outside the nacelle and can rotate around a first rotating shaft and a second rotating shaft relative to the nacelle, and the first rotating shaft is perpendicular to the second rotating shaft. According to the tilting rotorcraft, the winglet is rotatably arranged outside the nacelle, the winglet can rotate relative to the nacelle while the winglet tilts along with the nacelle, and in the transition state of the tilting rotorcraft, the winglet can rotate relative to the nacelle, so that the winglet can rotate relative to the nacelle; the extending winglet is always exposed in an incoming flow environment coupled by rotor slip flow and front incoming flow with the minimum projection area, and the resistance of the extending winglet in a transition state of the tilting rotorcraft is reduced to the maximum extent. Meanwhile, when the tilting rotorcraft flies forwards, the maneuverability of the tilting rotorcraft can be improved by adjusting the relative positions of the small wings and the nacelles, rolling torque is generated on the rotorcraft body, and additional control torque is generated on the rotorcraft body.
本发明公开一种倾转旋翼机,包括短舱和小翼,小翼可转动地设置于短舱的外部,小翼能够相对于短舱绕第一转轴、第二转轴转动,第一转轴垂直于第二转轴。本发明的倾转旋翼机,小翼可转动地设置于短舱的外部,在小翼随短舱倾转的同时,小翼能够相对于短舱转动,在倾转旋翼机的过渡状态下,可通过使小翼相对于短舱转动,使外伸小翼始终以最小投影面积暴露在旋翼滑流与前方来流所耦合出的来流环境中,最大幅度地减小外伸小翼在倾转旋翼机的过渡状态中的阻力。同时,可作动的外伸小翼在倾转旋翼机的前飞状态下,可以通过调整小翼与短舱的相对位置,对机身产生滚转力矩,对机身产生额外操纵力矩,增加倾转旋翼机的机动性。
