Parachute cord contraction and release device

Abstract

The invention discloses a parachute cord contraction and release device, comprising a box body. The box body is internally provided with at least two winding wheels and cord guiding wheels for windingparachute cords. Each winding wheel is provided with two guide grooves for winding, two parachute cords are wound on the two guide grooves, and the two parachute cords symmetric relative to the parachute are reversely wound on the two guide grooves for winding; each winding wheel is provided with a motor for driving the winding wheel to rotate, each motor is provided with a motor drive, and the motor drives are connected with a flight control board and a power source. According to the parachute cord contraction and release device, the box body is connected with the parachute cords through thecord guiding wheels, during the descending flight process of the parachute, the flight control board forms a control command through receiving a remote control signal or automatically detecting the error between the position of the parachute and the target landing point, to drive the corresponding motors to contract / release the parachute cords, so that the parachute always flies toward the targetlanding point.

Description

technical field [0001] The invention relates to the technical field of aircraft control system design, and is specifically embodied as an autonomous navigation parachute device capable of automatically realizing parachute flight trajectory control by changing the length of the parachute according to the requirements of the landing point of the parachute. Background technique [0002] With the development of modern flight technology, parachutes have been endowed with a wider range of uses, playing an important role in the recovery and homing of traditional aviation and aerospace vehicles, as well as national defense, lifesaving, and delivery of important materials. [0003] For example, in aerospace, in 1997, after the United States successfully landed on Mars with an inflatable airbag landing system, France, Russia and the United States cooperated to design a hot air balloon Mars landing system using solar energy as a heat source, and carried out a simulation test on the eart...

AI Technical Summary

Problems solved by technology

[0009] According to the above-mentioned technical problems, a parachute and parachute retractable device is provided, which is used to solve the control of the existing parachute for the landing point, but it is only limited to the control of the release point, that is, it is released under a suitable position and flight conditions. , but in the process of parachute descent, the automatic control of flight trajectory and landing point cannot be realized.
