Unmanned aerial vehicle retardation releasing device

Abstract

The invention provides an unmanned aerial vehicle retardation releasing device. The unmanned aerial vehicle retardation releasing device comprises a head cover, a middle cabin, a tail skirt, a retarder parachute, a controller and a cutting rope. The middle cabin is a hollow cylinder, one end of the middle cabin is connected with the bottom face of the hemispherical head cover, the other end of themiddle cabin is connected with the upper bottom of the circular-table-shaped tail skirt, and an unmanned aerial vehicle is fixed to the interior of a cavity formed by the head cover and the middle cabin; and the retarder parachute and the controller are installed in the tail skirt, and the cutting rope is bonded to the inner surfaces of the head cover and the middle cabin and the joint of the middle cabin and the tail skirt along the axis of the middle cabin in an axially symmetrical mode. According to the unmanned aerial vehicle retardation releasing device, the unmanned aerial vehicle can be rapidly and effectively released from a parent aircraft, and successful take-off of the unmanned aerial vehicle can be ensured.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle airborne delivery device. Background technique [0002] Our country has a vast land area and long borders. Border inspection requires a lot of manpower and material resources. Moreover, a large part of the border is located in high-altitude areas or in large forests, making border inspections difficult. At the same time, my country's forest coverage is vast, and forest fire prevention and disaster relief are difficult. The technical means commonly used now mainly include satellite reconnaissance, manned and machine patrols, and manual patrols. The disadvantages of satellite reconnaissance and manned aircraft inspections are the high working altitude and low resolution of photos, which cannot clearly capture clear images and video information of the incident site. The shortcoming of personnel inspection is that it cannot reach the incident site quickly, or it is impossible to enter the incident sit...

Problems solved by technology

The disadvantage of this method is that before launching the drone, the height of the parent aircraft must be lowered to the working height of the drogue parachute

Moreover, due to the large wingspan of the UAV, after the drogue parachute is deployed, it is very unstable after being disturbed by gusts of wind and strong airflow, and often fails to launch.
