Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a novel vertical take-off and landing fixed-wing unmanned aerial vehicle. Background Art

[0002] Vertical take-off and landing fixed-wing UAV is a heavier-than-air UAV that combines the advantages of both fixed-wing and rotary-wing. It has the advantages of low requirements for take-off and landing sites, good maneuverability, high cruising speed, and long flight time. It can take off and land vertically without a runway. Its vertical take-off and landing is achieved by taking-off and landing methods similar to those of helicopters and multi-rotors or by direct thrust.

[0003] During the flight and landing process of existing drones, the drones are prone to damage due to their high speed when landing. If a shock-absorbing device is installed on the drone, it is easy to shake due to air resistance, which in turn causes the drone to fly unsteadily and leads to poor safety. Utility Model Content
