Folding-wing unmanned aerial vehicle and launching method thereof

Abstract

The invention relates to a folding-wing unmanned aerial vehicle. The folding-wing unmanned aerial vehicle comprises a vehicle body, a front straight wing, a rear straight wing, a folding vertical finwhich is installed on the afterbody of the vehicle body, and a folding propeller assembly at the rear end of the vehicle body. One of the front straight wing and the rear straight wing is installed onthe top face of the vehicle body, the other one is installed on the bottom face of the vehicle body, and the front straight wing and the rear straight wing can be folded with the vehicle body as thecenter. According to the folding-wing unmanned aerial vehicle, in the unfolding process, the front straight wing and the rear straight wing can be symmetrically unfolded on the left and right sides with the vehicle body as the center, so that in the unfolding process, no difference exists between the balance forces of the front straight wing and the rear straight wing to the unmanned aerial vehicle body on the two sides, rotation of the vehicle body is not easily caused, the stability of the unmanned aerial vehicle is improved, and then the launching success rate of the unmanned aerial vehicleis improved.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a folding-wing unmanned aerial vehicle and a launching method thereof. Background technique [0002] With the development of science and technology, folding-wing UAVs have developed rapidly due to their advantages of being able to quickly fold and effectively reduce the large space they occupy during transportation, launch, and delivery. [0003] Traditional folding-wing UAVs generally use X-shaped airfoils, and the effective loading space of X-wing UAVs is small. Therefore, people have developed a Z-shaped folding UAV, see application number 201811601135.8 Published invention patent application, although the application overcomes the shortcomings of the traditional folding-wing UAV's small effective loading space, there are still technical defects: [0004] During the unfolding process, the left and right sides of the Z-shaped folding wings are unfo...

Problems solved by technology

[0003] Traditional folding-wing UAVs generally use X-shaped airfoils, and the effective loading space of X-wing UAVs is small. Therefore, people have developed a Z-shaped folding UAV, see application number 201811601135.8 Published invention patent application, although the application overcomes the shortcomings of the traditional folding-wing UAV's small effective loading space, there are still technical defects:

[0004] During the unfolding process, the left and right sides of the Z-shaped folding wings are unfolded asymmetrically with the fuselage as the center, so that the balance force of the Z-shaped folding wings on both sides of the UAV body is different during the unfolding process. , it is easy to cause the fuselage to rotate, which will affect the stability of the UAV, and then affect the success rate of UAV launch
