Miniature unmanned aerial vehicle catapult

Abstract

The invention provides a miniature unmanned aerial vehicle catapult. The miniature unmanned aerial vehicle catapult comprises a hydraulic motor piston rod, a catapulting force pre-tightening device, arear adjustable bracket, a sliding track, a clamping device, a front adjustable bracket and a buffering device; the rear adjustable bracket and the front adjustable bracket are respectively hinged atthe two ends of the sliding track and both consist of four telescopic rigid rods; the hydraulic motor piston rod is connected with the catapulting force pre-tightening device; the catapulting force pre-tightening device can be remotely controlled; the sliding track is designed as a ball sliding rail; the track can be spliced and is a foldable track; and the length of the track is determined by the total weight of the unmanned aerial vehicle and initial velocity required by take-off. The miniature unmanned aerial vehicle catapult has the advantages that larger catapulting force can be providedwithin a short distance, smaller space is occupied, the performance is more stable, remote control can be realized, requirements on the weight of the unmanned aerial vehicle and take-off places are lower, and therefore, the operation efficiency of the unmanned aerial vehicle can be enhanced.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle ejection, in particular to a novel unmanned aerial vehicle ejector. Background technique [0002] Due to the characteristics of small drones that do not require a dedicated airport, fast maneuvering, low cost of use, and simple maintenance and use, they have been widely used at home and abroad, and the take-off technology of drones has always played an important role in the process of using drones. status. At this stage, the take-off method of small UAVs with a take-off speed of less than 25m / s and a take-off weight of less than 100kg usually uses elastic ejection. The mechanical kinetic energy of the aircraft accelerates the UAV to the required speed for safe take-off in a short time. Therefore, the length of the rubber band in the traditional ejection system usually needs to be several meters or even tens of meters long, which occupies a large area and is difficult to deploy and...

At this stage, the take-off method of small UAVs with a take-off speed of less than 25m / s and a take-off weight of less than 100kg usually uses elastic ejection. The mechanical kinetic energy of the aircraft accelerates the UAV to the required speed for safe take-off in a short time. Therefore, the length of the rubber band in the traditional ejection system usually needs to be several meters or even tens of meters long, which occupies a large area and is difficult to deploy and withdraw. , the time to prepare for take-off is too long, on the other hand, it also limits the take-off weight of the UAV, and there are fewer applicable models
