The invention provides a turnable quadrotor unmanned aerial vehicle, which is composed of a vehicle body, a turnable device and a power module, wherein the power module comprises a propeller, a brushless motor and an electronic speed regulator, the turnable device comprises a connecting block, a screw, a steering engine and a bearing, the vehicle body comprises a center pan-tilt of the quadrotor unmanned aerial vehicle and four vehicle arms of the unmanned aerial vehicle. The quadrotor unmanned aerial vehicle has the beneficial effects that compared with most quadrotor unmanned aerial vehicles, the quadrotor unmanned aerial vehicle is additionally provided with the turnover device, the directions of propellers can be automatically adjusted after the vehicle body is turned over, normal flight of the unmanned aerial vehicle is guaranteed, when one wing of the unmanned aerial vehicle fails, balance of the momentum moment of the unmanned aerial vehicle can be guaranteed through slight inclination angles of a pair of diagonal propellers, the unmanned aerial vehicle can continuously and normally fly, the reliability of the unmanned aerial vehicle is improved, more complex tasks can be executed, the maneuvering characteristics of the unmanned aerial vehicle are enhanced, and the practical value of the unmanned aerial vehicle is greatly enhanced.

本发明提供了一种可翻转式四旋翼无人机，本发明由机体、可翻转装置、动力模块三个模块组成，所述动力模块包括：螺旋桨、无刷电机、电子调速器，所述可翻转装置包括连接块、螺丝、舵机、轴承，所述机体包括：四旋翼无人机的中心云台、无人机的四个机臂。本发明的有益效果是：本发明相比于大多数的四旋翼无人机，加装了可翻转装置，可在机体翻转之后自行调整螺旋桨方向，保证飞行器正常飞行，且当无人机某一机翼失灵时，其可通过一对对角螺旋桨略倾斜角度以保证其动量矩平衡，使其能继续正常飞行，使无人机可靠性提高，能够执行更加复杂的任务，增强了无人机的机动性能，大幅增强无人机的实用价值。
