Problems solved by technology

The disadvantage of this launch method is that it has high requirements on the material of the launch tube and the surface roughness of the inner wall of the launch tube, which directly leads to higher production costs of the launch tube, and the service life of the launch tube is very short.

Abstract

The invention discloses a barrel type launching device capable of realizing launching of a small-sized flexible-wing unmanned plane. The plane can be emitted out of a barrel by taking elastic potential energy of elastic elements which are symmetrically distributed in a central symmetry manner about the center of a cross section of the launching barrel as a power source. In a non-launching state, the plane is constrained in the barrel by a locking mechanism; in a launching state, the plane can be kept in a correct posture under the action of a launching guide rail and an orientation button. The locking device is controlled by a person to determine whether the plane is launched.

Description

Technical field [0001] The invention relates to a launching device for a small flexible-wing unmanned aerial vehicle, in particular to a barrel-type ejection launching device which uses the elastic potential energy of a material as a power source. Background technique [0002] Since the launch of flexible-wing UAVs is still a relatively blank field in China, there are very few reference materials that can be searched and compared for flexible-wing UAV launch devices. At present, a UAV with flexible wings in the United States is in the prototype development stage. Its launch method is to use gunpowder to burn at the bottom of the launch tube to generate a sufficient amount of high-temperature and high-pressure gas, which is used as a power source to push the UAV out of the tube to complete the launch process. The disadvantage of this launch method is that it has high requirements on the material of the launch tube and the surface roughness of the inner wall of the launch tube...
