Embodiment Construction

[0034] The preferred embodiment of the present invention's pre-open parachute is for example Figures 2 to 5 shown, including:

[0035] A pair of slow-descent air balloon parachute 20 is an axisymmetric structure with respect to a central axis X as a whole, and the double slow-descent balloon parachute 20 includes an inflatable cover portion 21 surrounding a first resistance generation space 22, the inflatable cover The part 21 is a hollow body made of flexible material and has an inflatable space 211, and the inflatable cover part 21 has an air nozzle 212 communicating with the inflatable space 211, and the inflatable cover part 21 surrounds the inflatable cover part 21 with a surrounding surface 213. The first resistance generation space 22, and the free end of the surrounding surface 213 is a first port portion 214, the first port portion 214 is made of a hard material without deformability and surrounds an open port, and the first port portion 214 is formed as an open port...

Abstract

Disclosed is a pre-opening parachute. The pre-opening parachute is mainly formed by connecting a balloon parachute with double-slowing descending force and a pre-opening parachute to two ends of a universal joint; the balloon parachute with double-slowing descending force has an inflating dome to inflate with air and generate buoyancy; the balloon parachute with double-slowing descending force generates buoyancy after inflation, and completes opening of the parachute by pulling up the pre-opening parachute, without the help of potential energy generated by the dropping height or kinetic energy generated by displacement, thus being very convenient to use and having good environmental adaptability. When the pre-opening parachute of the present invention descends, the buoyancy force of the air inflating dome provides a slow-descent effect, and the first resistance generation space of the balloon parachute with double-slowing descending force and the second resistance generation space of the pre-opening parachute respectively impact the air to generate first resistance and second resistance hindering descent. The present invention provides upward acting force at three positions to achieve the slow-descent effect, thus definitely opening the parachute in a short time, smoothly and slowly descending, and improving the use comfort and safety.

Description

technical field [0001] The present invention relates to a pre-opening parachute, which is related to the structure of the parachute. Background technique [0002] Parachute, a landing device that provides a safe and slow descent from a high place, and there are many types of parachutes. Among them, the projectile and towed parachutes need to have sufficient height or space to match the airflow resistance or kinetic energy of displacement when falling from a high altitude And after a period of time, it can be determined to open, but the high-rise buildings located in the streets full of buildings have the dilemma of being unusable because they do not have sufficient height and space. [0003] Therefore, there is another figure 1 The balloon parachute 10 shown mainly comprises a double-layer structure composed of an airflow resistance cover 11 and an inflatable ball 12, the inflatable ball 12 and the airflow resistance cover 11 are connected with a plurality of first cables 1...
