Pneumatic muscle parachute

Abstract

The invention discloses a pneumatic muscle parachute. The basic idea is that a pneumatic muscle long rope replaces a rope strip on the pneumatic muscle parachute, and one set of gas supply system andone set of control system are additionally provided. A new pneumatic muscle has the characteristics of light weight, large tension, high contraction ratio of 63%, excellent tension uniform and vertical hoisting performance and less gas consumption. The elasticity of a parachute cord (1) and a connecting chord (3) of the pneumatic muscle parachute becomes larger after being inflated; and the straightening forces of the parachute cord (1) and the connecting chord (3) of the pneumatic muscle parachute can be reduced in a straightening stage. A closure chord (2) does not adopt a cut-off method butadopts a gradual and slow extending method to control parachute opening so as to reduce parachute opening overload. In the parachute descending stage, a parachute canopy can be pulled to deform by controlling the retraction and extension of the parachute cord (1) so as to control the horizontal moving speed and direction of the parachute. During landing, the parachute cord (1) or the connecting chord (3) can be enabled to rapidly retract to increase the tension, and the tension can enable the parachute canopy to descend in an accelerated manner to increase the resistance; and the tension canalso enable air-dropped articles to land in a decelerated manner. The pneumatic muscle parachute is safe, reliable and easy to use; and the weight of the pneumatic muscle parachute is also lighter.

Description

technical field [0001] The invention relates to a parachute, in particular to a parachute capable of actively controlling the movement of an umbrella system. Background technique [0002] In recent years many efforts have been made to find a parachute capable of controlling the movement of the parachute system. Chinese patent No. ZL20042005356.5 patent specification discloses a parachute, which is mainly composed of canopy, parachute, safety belt, hydrogen cylinder, conduit, etc., and the parachute can be suspended in the air when hydrogen is charged into the parachute; After the parachute falls into the sea, the umbrella body can be used as a lifeboat again, but this parachute also has problems such as low efficiency, heavy weight, and poor safety. [0003] My invention patent specification No. 201110276524x discloses a retractable tension airbag device, which is also a pneumatic muscle. Injected with pressurized gas, the pneumatic muscles contract and create tension. Th...
