Unmanned aerial vehicle parachute system

Abstract

The invention discloses an unmanned aerial vehicle parachute system. The unmanned aerial vehicle parachute system comprises a parachute device; the parachute device comprises a parachute catapulting cabin, a parachute and a catapulting plate; a cabin cover is arranged at a cabin opening of the parachute catapulting cabin, one end of the cabin cover is hinged to the cabin opening, and the other endof the cabin cover is locked and closed at the cabin opening through a parachute opening mechanism; the catapulting plate is mounted to catapulting springs through the locked and closed cabin cover in a pressed mode, wherein the catapulting springs are evenly distributed on the circumference in the parachute catapulting cabin; the folded parachute is arranged between the cabin cover and the catapulting plate; and a parachute rope of the parachute penetrates through a center hole of the catapulting plate to be fixedly connected to the cabin bottom of the parachute catapulting cabin. Accordingto the unmanned aerial vehicle parachute system, the parachute can be catapulted out of the parachute catapulting cabin more quickly, and due to the fact that balance force is adopted to catapult theparachute, the catapulting successful rate can be effectively increased.

Description

technical field [0001] The invention relates to supporting components of an unmanned aerial vehicle (UAV), in particular to a parachute system for an unmanned aerial vehicle. Background technique [0002] At present, the parachute landing system of the rotor UAV mainly adopts the mode of ejecting the parachute from the ejection chamber. After the parachute is ejected out of the ejection chamber, the parachute is opened due to the effects of air resistance, aircraft pulling force and its own gravity, and the parachute generates upward pulling force to the aircraft to protect the aircraft from landing safely. [0003] The existing rotor parachute ejection chamber mainly uses a single spring to realize the parachute ejection function. When a single spring is ejected, the ejection plate will be stuck due to uneven force on the ejection plate; and, due to the use of a single The root spring provides the ejection force, and the effective length of the ejection parachute compartme...

AI Technical Summary

Problems solved by technology

[0003] The existing rotor parachute ejection chamber mainly uses a single spring to realize the parachute ejection function. When a single spring is ejected, the ejection plate will be stuck due to uneven force on the ejection plate; and, due to the use of a single The root spring provides the ejection force, and the effective length of the ejection chamber is relatively long, resulting in a relatively long ejection process of the parachute system, and the minimum parachute opening height of the rotorcraft is relatively high
