Rotor wing unmanned aerial vehicle capable of approaching fast

Abstract

The invention discloses a rotor wing unmanned aerial vehicle capable of approaching fast. The rotor wing unmanned aerial vehicle comprises a fuselage body, a launching shell and a launching device, wherein a coaxial double-blade device is arranged at the top of the fuselage body; the coaxial double-blade device comprises an inner shaft, a first bevel gear is arranged at the bottom of the inner shaft, and an upper rotating disc is arranged on the top position of the inner shaft; an outer shaft is arranged in the middle part of the inner shaft in a sleeving connection mode, and a task device isarranged on the lower part of the fuselage body; the launching shell is matched with the fuselage body of foldable blades, the launching shell comprises two cambered-surface shells which are same in size, wherein the cambered-surface shells are connected with each other in a matched mode; and the launching device is internally provided with a launching cavity matched with the launching shell, andthe launching device is internally provided with a device for catapulting the launching shell. The rotor wing unmanned aerial vehicle overcomes the technical shortcomings of the prior art, has a reasonable structure, adopts coaxial propeller-reversing layout, has the foldable blades, and can quickly approach a target area for hovering or flight operation.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a rapidly approaching rotor unmanned aerial vehicle. Background technique [0002] At present, drone technology is developing rapidly, and many traditional industries have begun to slowly introduce the application of drones, promoting the intelligent upgrading of the industry. [0003] UAVs on the market are usually dominated by rotary-wing UAVs and fixed-wing UAVs. Rotary-wing UAVs can hover in the air and perform work over designated locations, but they have disadvantages such as short flight time and slow flight speed; fixed-wing UAVs fly fast and can complete work tasks in a large area in a short time, but It cannot hover, and has high requirements on the take-off and landing site, so it is not convenient for quick deployment and quick use. [0004] In actual use, if the drone needs to approach the work area at high speed and then hover for work, a new type...
