Remote control parachute

Abstract

The invention relates to the technical field of aircraft design, and discloses a remote control parachute. The remote control parachute mainly comprises a load, parachute cords, a parachute canopy and a remote controller, wherein rectangular holes are formed in the parachute canopy. An operator sends out a remote control instruction based on an error between the current position of the parachute and the target landing point of the parachute; a flight control mainboard receives the remote control instruction and sends out a baffle rotation angle instruction to a stepper motor; and then the stepper motor drives a baffle to adjust the opening degree of the holes so as to control the descending trajectory of the parachute. According to the remote control parachute disclosed by the invention, the accuracy of landing points of the parachute can be significantly improved, and unnecessary economic loss caused by the situation that the landing points of traditional parachutes cannot be controlled is reduced; and besides, in the process of changing the descending trajectory of the parachute, only a small-power electric source enabling the stepper motor to drive the baffle needs to be provided, and other power does not need to be used, so that the remote control parachute is both economic and environment-friendly.

Description

technical field [0001] The invention relates to a remote control parachute, which belongs to the technical field of aircraft design. Background technique [0002] The working principle of the parachute is that after the parachute is opened at a certain height, due to the action of the airflow and the inner wall of the canopy, the canopy will open rapidly, and the descending speed will continue to increase. With the continuous increase of air resistance, its descending speed decreases, and gradually reaches the equilibrium speed until a safe landing is achieved. Although parachutes have been widely used in various fields, the current application level cannot realize the active control of the parachute descent trajectory, and the accuracy of the parachute drop point cannot be guaranteed. Especially when recovering a spacecraft, if it encounters windy weather, it will directly cause the spacecraft to deviate from the scheduled landing point by dozens or even hundreds of kilome...

Although parachutes have been widely used in various fields, the current application level cannot realize the active control of the parachute descent trajectory, and the accuracy of the parachute drop point cannot be guaranteed

Especially when recovering a spacecraft, if it encounters windy weather, it will directly cause the spacecraft to deviate from the scheduled landing point by dozens or even hundreds of kilometers; if it encounters complex terrain environments, such as jungles, mountains, waters, etc., it may directly Damage to the spacecraft will bring great difficulties to search and recovery, and the resulting economic and property losses will also greatly increase
