Tilt-rotor UAV (Unmanned Aerial Vehicle)

Abstract

The invention relates to the technical field of UAVs (Unmanned Aerial Vehicles), and provides a tilt-rotor UAV. The tilt-rotor UAV comprises a machine body, wings, rotor wings, a horizontal tail and a vertical tail, wherein two pairs of horizontal wings and two pairs of rotor wing power systems are arranged at two sides of the machine body; the rotor wings are used as power output components and are rigidly connected with the wings; the wings and the rotor wing power components can rotate around a wing shaft in the horizontal direction and the vertical direction through an internal transmission structure, so that switching between a rotor wing mode and a fixed wing mode is realized. The tilt-rotor UAV disclosed by the invention integrates two modes of a multi-rotor wing mode and the fixed wing mode, vertical takeoff and landing and hovering can be carried out under the multi-rotor wing mode, the tilt-rotor UAV is enabled to takeoff and land without a runway or other devices, not only can hovering, low-speed forward flight, backward flight and sideward flight be realized by a single air vehicle, but also high-speed long-distance flight can be realized by the single air vehicle, the advantages of the multi-rotor wing mode and the fixed wing mode are blended, and a wide application prospect is obtained.
