Embodiment Construction

[0011] like figure 1 As shown, the present invention is made up of capsule body 1, axial stretching device 2 and inflation valve 3, and airbag stretching device 2 is installed in capsule body 1, and the gas supply port of inflation valve 3 communicates with the inner chamber of capsule body 1.

[0012] like figure 2 , 3 As shown, the capsule body 1 is composed of a group of valve-shaped capsule skins 11 and a group of longitudinal ribs 12. A group of valve-shaped capsule skins 11 are made of airtight airbag cloth. Adjacent valve-shaped capsule skins are heat-sealed at the junction Bonded together, a group of longitudinal ribs 12 is composed of strong and flexible threads, and a group of longitudinal ribs 12 are respectively fixed at the junction of adjacent flap-shaped capsule skins. The petal-shaped bag skin 11 can be made of airtight balloon cloth, airship airbag cloth or film material, and the longitudinal rib 12 can be made of high-strength nylon rope, Kevlar or other p...

Abstract

An umbrella unfolding type airship air bag is characterized by comprising a bag body (1), an axial extending device (2) and a charge valve (3), wherein the air bag extending device (2) is arranged in the bag body (1), and a gas supply opening of the charge valve (3) is communicated with the inner cavity of the bag body (1). The umbrella unfolding type airship air bag has the advantages that, by changing the structural form of the air bag, the volume of the air bag can be effectively shrunk when the volume of internal lifting power gas on the ground and at low-aptitude height is small; the air is unfolded by using the inner and outer pressure difference of the air bag without arranging an auxiliary air bag inside when the volume of internal lifting power gas of the air bag expands in the air. Therefore, the umbrella unfolding type airship air bag has the advantages of low manufacturing cost, facilitates the manufacture of large high-altitude airships and is contributive to the realization of high-altitude flying.

Description

technical field [0001] The present invention relates to airships, in particular to airbags for airships. Background technique [0002] At present, airship airbags are divided into three types according to their airbag structures: soft airbags, hard airbags and semi-rigid airbags. Their common feature is that during operation, the shape and total volume of the airship airbag approximately do not change or change slightly, while the helium inside expands with the decrease of air pressure and / or the increase of temperature, and a large amount of space should be left in the airship airbag. To meet the volume change requirements of helium expansion, the airbag of the soft airship needs to be equipped with an auxiliary airbag, and the rigid airship needs to have a huge hard-shell outer body. The airbag of the airship works on the ground and at low altitudes and flies at high altitudes The size and shape of the external capsule are the same. Thereby, present known airship airbag ...
