The invention belongs to the technical field of unmanned flight and particularly relates to a medium-sized tilt rotor unmanned aerial vehicle. The unmanned aerial vehicle comprises a fuselage, an empennage and two wings, wherein the empennage and the two wings are arranged on the fuselage, each wing comprises a tilting outer wing section and an inner wing section, one end of each inner wing section is fixedly connected with the fuselage, and the other end of each inner wing section is rotatably connected with the corresponding tilting outer wing section; the tilting outer wing section comprises a variable-pitch rotor wing, an outer wing section, a nacelle and an expansion wing, one end of the outer wing section is rotationally connected with the inner wing section through a rotating shaft, and the other end of the outer wing section is slidably connected with the expansion wing; the nacelle is arranged on the outer wing section, a variable-pitch rotor wing is arranged at the top of the nacelle, and a rotor wing rotation driving system used for driving the variable-pitch rotor wing to rotate is arranged in the nacelle. According to the aircraft, the extension length and angles of the rotors relative to the aircraft body can be adjusted so as to adapt to different flight mission requirements, and flight efficiency is improved.

    本发明属于无人飞行技术领域,特别涉及一种中型倾转旋翼无人飞行器。包括机身及设置于机身上的尾翼和两个机翼,其中机翼包括倾转外翼段和内翼段,内翼段的一端与机身固定连接,另一端与倾转外翼段可转动地连接。倾转外翼段包括可变距旋翼、外翼段、短舱及扩展翼,其中外翼段的一端通过转轴与内翼段转动连接,另一端可滑动地连接有扩展翼;短舱设置于外翼段上,并且顶部设有可变距旋翼,短舱内设有用于驱动可变距旋翼转动的旋翼旋转驱动系统。本发明中的飞行器可以调节展长和旋翼相对机身角度,以适应不同飞行任务需求,提升飞行效率。
