Landing cushion gasbag

Abstract

The invention relates to a landing cushion gasbag, which comprises a frame type gasbag, wherein the frame type gasbag is communicated with gas resource in a landing cushion system (1), and the upper end of the frame type gasbag is communicated with the bottom of an unmanned aerial vehicle. The landing cushion gasbag has the advantages that: the frame type gasbag is communicated with the gas resource in the landing cushion system, and the gas resources such as a mini-type high-pressure gas bottle or a gas generating device, and the like, are used for aerating the frame type gasbag when the unmanned aerial vehicle is landed with a parachute, so that the gasbag can provide cushion to the unmanned aerial vehicle when loading after the frame type gasbag is aerated. As the cubage of the frame type gasbag is far less than the existing gasbag, the package of the gasbag is less, the weight is light, and the gasbag can be aerated without atmosphere source.

Description

technical field [0001] The invention relates to an unmanned aircraft, in particular to a landing buffer system for a parachute landing UAV, especially a landing buffer airbag in the landing buffer system. Background technique [0002] The UAV recovery system is generally composed of a parachute system and a landing buffer system. The parachute system slows down the UAV and makes it land at a certain speed, while the landing buffer system absorbs the impact energy of landing to further reduce the impact of the UAV. Landing speed to ensure safe landing of the UAV. The landing cushion airbag is a cushioning method with relatively simple structure, low cost and wide application range among many cushioning systems. [0003] Landing buffer airbags are generally made of fabric-coated materials, and are pre-inflated and deployed by their own air source. When landing, the gas in the airbag is compressed by the impact energy of landing, and the gas is released after blasting through ...

AI Technical Summary

Problems solved by technology

Such materials are generally thick, high in use and processing costs, and heavy in quality. They are not suitable for storage and deployment in the abdomen of drones, and also increase material costs and processing costs;

[0006] 3. UAVs are required to have high maneuverability and maintainability. However, due to the complicated installation and large size of the existing airbags, they are easily damaged when the landing site is not good, so that the UAV cannot be repaired in time, which restricts the use of unmanned airbags. Improvement of machine maneuverability
