The embodiment of the invention discloses a foldable rotor system for a high subsonic velocity tilt rotor aircraft, relates to the technical field of high-speed vertical take-off and landing aircrafts, and can reduce air resistance while realizing the functions of rotation, pitch change and folding. The foldable rotor mainly works in an unfolding mode and a folding mode, has rotational degrees of freedom in three directions, and can achieve the functions of rotation, pitch change and folding. When the high subsonic velocity tilt-rotor aircraft vertically takes off, lands and flies in a rotor wing mode, the rotor wings of the high subsonic velocity tilt-rotor aircraft are unfolded and are similar to a rotor wing system of a tilt-rotor aircraft; when the high subsonic velocity tilt rotor aircraft flies in a jet mode, the engine is switched into a turbofan mode, meanwhile, the rotors are folded backwards to reduce resistance, and high-speed cruise is achieved. Therefore, air resistance can be reduced while the functions of rotating, pitch changing and folding are achieved.

    本发明实施例公开了一种用于高亚声速倾转旋翼飞行器的可折叠旋翼系统,涉及高速垂直起降飞行器技术领域,能够在实现转动、变距以及折叠的功能的同时,还能够减小空气阻力。本发明包括:可折叠旋翼主要以展开与折叠两种模式工作,具有三个方向的转动自由度,可实现转动、变距以及折叠的功能。当高亚声速倾转旋翼飞行器以旋翼模式垂直起降与飞行时,其旋翼展开,类似于倾转旋翼机的旋翼系统;当高亚声速倾转旋翼飞行器以喷气模式飞行时,发动机切换为涡扇模式,同时旋翼向后折叠以减小阻力,实现高速巡航。从而在实现转动、变距以及折叠的功能的同时,还能够减小空气阻力。
