Problems solved by technology

However, when the parafoil is ready to open after being thrown out from the aircraft cabin, the folded shape hinders the inflation of the air chambers, especially the air chambers on both sides. Because of the constraints of the control ropes, the inflation conditions are worse, which often leads to the parafoil opening time being too long However, if the parafoil cannot be inflated quickly, the parafoil will not be able to fly normally or even stall, which will bring safety hazards

Abstract

The invention provides a parafoil structure capable of being quickly opened and an opening method thereof. The parafoil structure comprises a hollow cavity with the front edge open and the rear edge sealed, the center of the cavity is divided into a plurality of air chambers through wing ribs, vent holes are formed in the wing ribs, and the lower ends of the wing ribs are connected with parafoil cords; the left end and the right end of the cavity are connected with inflation channels in a fully-closed state, the inflation channels are connected with the adjacent air chambers through pressure release valves, and inflation devices and deflation valves are arranged in the inflation channels. The parafoil inflating structure provided by the invention can help the parafoil to quickly form an inflating opening state for normal sliding of the parafoil after the parafoil is thrown out of an aircraft cabin, so that the air-drop safety of the parafoil is ensured.

Description

technical field [0001] The invention relates to the field of parafoil opening devices, in particular to an auxiliary device and an opening method for rapidly opening a parafoil. Background technique [0002] A parafoil is a kind of parachute that can glide and fly in the air. Whether it is for leisure, entertainment, commercial use, long-distance delivery, aerospace, etc., parafoils have been widely used. The airfoil of the commonly used inflatable parafoil is formed by using the initial speed and falling speed of the parafoil after the parafoil is thrown from the aircraft cabin to inflate the air chamber against the wind, and the parafoil canopy becomes a flying wing, thereby Can glide in the air. However, when the parafoil is ready to be opened after being thrown from the aircraft cabin, the folded shape hinders the inflation of the air chambers, especially the air chambers on both sides. Because of the constraints of the control rope, the inflation conditions are worse, ...
