AI Technical Summary

Technical Problem

Existing UAV orbital launch and release devices are complex in structure and have low reliability, which can easily lead to launch mission failure.

Method used

The locking and triggering devices employ purely mechanical components. The locking and release of the drone are achieved by connecting and separating the trolley from the drone. The reliable separation of the drone from the trolley is achieved by using a pre-tension spring and a U-shaped clamp.

Benefits of technology

It enables reliable, simple, and low-cost catapult launch of UAVs, with a simple structure and convenient operation, thus improving the success rate of launch missions.

Abstract

This invention discloses a release device and method for catapult-launched unmanned aerial vehicles (UAVs), comprising a trolley, a launcher, and a first triggering device. The upper part of the trolley can be connected to the UAV via a locking device. The bottom of the trolley includes a slider. The trolley is equipped with a second triggering device. The launcher has a slide rail that cooperates with the slider. The first triggering device is located at the end of the slide rail. When the UAV moves on the trolley to the first triggering device, the second triggering device, under the action of the first triggering device, can separate the UAV from the trolley, thereby releasing the UAV. The device of this invention uses purely mechanical components to lock and release the UAV. Compared with conventional electric unlocking devices, it is simpler and more reliable in structure, easier to operate, lower in cost, and reusable.
