Abstract

The invention discloses a reusable unmanned aerial vehicle catapulting device, which comprises a catapulting base, wherein a guiding mechanism is arranged on the upper surface of one end of the catapulting base, a catapulting mechanism is arranged on the lower surface of the other end of the catapulting base, the guiding mechanism comprises a sliding groove, the sliding groove is formed in the upper surface of one end of the catapulting base, a clamping base is slidably connected into the sliding groove, and a clamping groove is formed in the surface of the clamping base. The device has the beneficial effects that water flow is introduced into a rubber cylinder through a water inlet pipe, the water flow is accumulated in the rubber cylinder to expand the rubber cylinder, the outer wall ofthe expanded rubber cylinder makes contact with an arc plate, then the arc plate gets close to the inner wall of a circular cavity, and after the arc plate makes contact with the inner wall of the circular cavity, the rubber cylinder cannot be continuously expanded, so that the rubber cylinder is prevented from being expanded to deform excessively to lose elasticity, and the defect that an elasticpart in an existing unmanned aerial vehicle hydraulic catapulting device cannot be repeatedly used to cause waste is effectively overcome.

Description

technical field

[0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a reusable unmanned aerial vehicle ejection device. Background technique

[0002] There is a big difference in how drones and manned aircraft take off. Almost all manned fixed-wing aircraft can take off after long-distance taxiing on the runway to obtain enough lift, but UAVs are different. There are many launching methods. UAVs of different sizes can be launched by hand , vehicle launch, ejection, rocket booster and other launching methods. The purpose of UAV ejection take-off is to shorten the taxiing distance. When the UAV is limited by the venue and cannot glide and accelerate to provide enough lift, it needs to use the ejection take-off method. The take-off and ejection are powered by highly stretchable elastic elements to provide the acceleration required for the drone to take off, which is suitable for small drones.

[0003] UAVs often need to provide gr...
