Problems solved by technology

The airbag skins of blimps and semi-rigid airships are made of airtight rubberized fabric. The overall structure and shape of the airbags are maintained by the internal gas pressure. In order to meet the expansion and contraction of the internal hydrogen or helium volume While the overall appearance remains unchanged, the airbag must be equipped with an air-filled auxiliary airbag, and an airbag pressure system needs to be installed to control the gas pressure in the airbag. The weight is large, the energy consumption for maintaining the shape and rigidity of the airbag is large, and the structure is complex. Manufacture It is very difficult to make an extra-large airship to fly in high altitude and stratospheric space
The rigid airbag of a rigid airship is composed of a rigid shell and an internal airtight flexible capsule. The airship garage or parking place is not easy to disassemble and transport; due to its heavy weight and large structural size, it is also difficult to meet high-altitude and stratospheric space flights
Currently known lighter-than-air airship airbags have the disadvantages of large volume on the ground and at low altitude, large energy consumption for maintaining the shape, heavy weight, complex structure, and difficulty in high-altitude flight.

Embodiment Construction

[0006] The airbag is made of airtight airbag cloth into a strip-shaped airtight airbag. The inflation nozzle is a commonly used airbag inflation valve, which is installed on the skin of the airbag. The material of the slide plate and the bottom plate can be light weight metal (such as aluminum alloy, magnesium alloy, titanium alloy, etc.) and composite materials (such as carbon fiber, plastic, etc.) made. The slide plate is installed on the bottom plate through the chute, and one end of the bottom plate and one end of the slide plate are glued to the airbag skin respectively. fixed on the other end of the bottom plate. The airship power propulsion device is installed on the bottom plate, and the airship flight system, including the flight control system, mission system, power supply system, etc., is installed on the airbag expansion device to form the airship. Lifting gas (gas lighter than air, such as hydrogen, helium, etc.) is filled in the airbag. The electric winch is c...

Abstract

The invention relates to an airship balloon, the capability of the airship balloon is variable, and consists of a balloon (1), an inflation mouth (2) and a balloon telescopic device which can be used for stretching the balloon in axial direction. the balloon telescopic device is arranged in the balloon (1); the air outlet of the inflation mouth (2) is communicated with the inner cavity of the balloon (1); the invention has the advantages that due to the balloon telescopic device which can be used for stretching the balloon in axial direction, when the airship climbs up to high, and when the relative pressure in the balloon is increasing, the balloon telescopic device can shorten the balloon in axial direction, and the capacity in the balloon is enlarged accordingly to reduce the stress of the balloon wall, thereby achieving the purpose of preventing the balloon wall from being damaged; at the same time, the aerodynamic appearance of the balloon which is in proper stiffness, and can be kept to help fly.

Description

technical field [0001] The present invention relates to airships, in particular to airbags for airships. Background technique [0002] At present, known lighter-than-air vehicles mainly include balloons and airships. Airship airbags are divided into three types according to their airbag structure: soft airbags, hard airbags and semi-rigid airbags. Their common feature is: the axial length of soft airbag and hard airbag all can not expand and contract in flight, and the diameter of its ellipsoid does not change either, so the total shape and total volume of airbag are constant. The airbag skins of blimps and semi-rigid airships are made of airtight rubberized fabric. The overall structure and shape of the airbags are maintained by the internal gas pressure. In order to meet the expansion and contraction of the internal hydrogen or helium volume While the overall appearance remains unchanged, the airbag must be equipped with an air-filled auxiliary airbag, and an airbag pres...
