Unmanned aerial vehicle parachute and unmanned aerial vehicle parachute control system

Abstract

The invention relates to the technical field of parachutes and in particular relates to an unmanned aerial vehicle parachute and an unmanned aerial vehicle parachute control system. The unmanned aerial vehicle parachute comprises a mounting bottom plate, a parachute body and a parachute barrel with an upper opening, wherein the parachute barrel is fixedly arranged on the mounting bottom plate to form a storage space for placing the parachute body; a catapult-launching device used for catapulting and launching the parachute body out of the parachute barrel is arranged in the storage space; theunmanned aerial vehicle parachute is characterized in that the catapult-launching device comprises a powder keg arranged on the mounting bottom plate fixedly; the parachute body is arranged on the upper part of the powder keg; gunpowder and an arc generator are sequentially arranged inside the powder keg from top to bottom; the arc generator is used for igniting gunpowder; the arc generator is connected with a controller, so that the arc generator is controlled to produce arc so as to ignite the gunpowder, and the gunpowder is burned to produce gases so as to pop up the parachute body. The unmanned aerial vehicle parachute disclosed by the invention has the advantages of being reliable in parachute opening effect, low in failure rate and high in repeated utilization rate.

Description

technical field [0001] The invention relates to the technical field of parachutes, in particular to a parachute for a drone and a control system for the parachute of the drone. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft operated by radio remote control telemetry equipment and its own program control device. There is no cockpit on board, but it is equipped with navigation flight control system, program control device and power and Power supply and other equipment, ground remote control and telemetry station personnel can track, locate, remote control, telemetry and digital transmission through data link and other equipment. Compared with manned aircraft, it has small size, low cost, easy to use, and adapts to various flights The characteristics of environmental requirements can be widely used in aerial remote sensing, meteorological research, agricultural aerial sowing, and pest control, as well as aerial reconnaissance, sur...

AI Technical Summary

Problems solved by technology

[0007] On the one hand, the drone parachute of the present invention is provided with gunpowder barrels and gunpowder for opening the parachute, adopts solid gunpowder with a weight less than 1.5g, and generates an arc to ignite the gunpowder through an arc generator, and the gas generated by the burning of the gunpowder pushes the umbrella body to open. Compared with the spring type parachute opening method of the UAV parachute in the prior art and the compressed gas jet parachute opening method, it solves the technical problems that the parachute opening method in the prior art has a complex structure, many parts, and a large overall weight , and solves the problem of reduced endurance of the unmanned aerial vehicle caused by the increase in the weight of the parachute. The present invention has the advantages of low overall weight of the parachute, simple structure, and not easy to damage; The power of the solid gunpowder is less than 0.2s from the arc ignition to the ignition time. The solid gunpowder instantly generates a large amount of gas, forming a strong air explosion force, so that the gas has a high speed and power, and can quickly eject the umbrella body, which solves the problem Due to the lack of ejection force and long ejection start time of traditional parachutes and the failure of the umbrella body to eject, especially in larger drones due to the weight of the parachute itself, the problem of insufficient ejection parachute force makes the parachute opening of the present invention reliable; in addition , the parachute of the present invention can be reused many times. After the parachute is used once, take out the gunpowder barrel and refill the solid gunpowder in the gunpowder barrel. The gunpowder is easy to carry, and the parachute can be conveniently and quickly replaced. The parachute can be put into the parachute, and the parachute can be used again. The operation of the whole process is extremely simple, and the operation can be completed outdoors, so that the reusing effect of the parachute of the present invention is reliable, and it solves the problem of complicated reusing process and low utilization efficiency of the parachute device in the prior art. Problems, such as the parachutes ejected from compressed carbon dioxide gas used in the prior art, require air compressors to inflate the cylinders when they are reused.
