Description

Technical Field

[0001] The utility model relates to the technical field of UAV mapping, in particular to an ejection device for a mapping fixed-wing UAV. Background Technique

[0002] The UAV ejection device is generally applicable to assist the takeoff of small UAVs. It drives the UAV to move through high-speed sliding, so as to reach within the threshold of the takeoff speed. Then, it decelerates by itself to provide a relative speed for the UAV, enabling the UAV to take off smoothly.

[0003] At present, when the existing UAV ejection device is in use, it is not convenient to adjust the ejection direction of the ejection device according to the mapping needs. When the ejection direction needs to be adjusted, the ejection device needs to be turned around. After turning around, due to the terrain problem, the stability of the ejection device needs to be adjusted again, which is time-consuming and laborious and affects the working efficiency of mapping. In view of this, we propose an ejection device for a mapping fixed-wing UAV to solve the above-mentioned problems. Content of the Utility Model
