The invention relates to the technical field of unmanned aerial vehicles, in particular to a long-endurance multi-rotor unmanned aerial vehicle based on novel aerodynamic layout, which comprises a vehicle body, a plurality of rotors are arranged on the peripheral side of the vehicle body, connecting rods connected with the vehicle body are arranged on the rotors, and first rotating pipes which are axially parallel to the length directions of the connecting rods and can rotate around the axes of the first rotating pipes are arranged on the connecting rods. According to the long-endurance multi-rotor unmanned aerial vehicle based on the novel aerodynamic layout, the cross section of the vehicle arm is configured to be in a water drop shape, the wind resistance of the vehicle arm of the unmanned aerial vehicle is reduced, energy loss is reduced, by controlling the vehicle arm to rotate, the posture of the vehicle arm can be adjusted while the unmanned aerial vehicle flies, the wind resistance of the vehicle arm is further reduced, energy loss is avoided, and the service life of the unmanned aerial vehicle is prolonged. Furthermore, the vehicle arms are divided into the fixed arms and the movable arms, and the movable arms are controlled to move through the second rotating pipes, so that the effect of enlarging the surface area of the side edges of the vehicle arms is achieved, the aerodynamic performance of the vehicle arms is changed, and larger lift force or sudden stop resistance is provided for the unmanned aerial vehicle.

    本发明涉及无人机技术领域,且特别涉及一种基于新型气动布局的长续航型多旋翼无人机,包括机体,机体周侧设有若干旋翼,旋翼上设有与机体连接的连杆,连杆上设有轴向与连杆的长度方向平行且可绕自身轴线转动的第一转管。该基于新型气动布局的长续航型多旋翼无人机,通过将机臂横截面构造成水滴状,减小了无人机机臂的风阻,降低了能量损耗,而通过控制机臂转动,则可在无人机飞行的同时实现对机臂姿态的调整,进一步降低了机臂风阻,避免了能量损耗,更进一步,将机臂分为固定臂和可移动的活动臂,并通过第二转管控制活动臂移动,则起到了扩大机臂侧边表面积的作用,改变机臂的气动性能,为无人机提供更大的升力或急停阻力。
