A weather-resistant stratospheric airship

Abstract

A weather-proof stratospheric airship comprises an airship skin. The skin comprises a weather-proof layer, a primer layer, a force bearing layer, an adhesive layer, a helium blocking layer and a thermal sealing layer sequentially from outside to inside, wherein the thermal sealing layer is a polyurethane film; the helium blocking layer is an aluminized polyester (Al-PET) film; the adhesive layer is made of polycarbonate; the force bearing layer is made of PBO plain weave fabric; the primer layer is made of double-component epoxy polyamide; the weather-proof layer is made of nanometer fluorocarbon coating. As the nanometer fluorocarbon coating is adopted, the weather-proof stratospheric airship enhances self-cleaning effect, ultraviolet resistance and environment protection ability of the weather-proof layer and greatly enhances weather resistance of the airship skin. The invention also relates to a manufacturing method of the airship skin.

Description

technical field [0001] The invention relates to an airship, in particular to a weather-resistant stratospheric airship. Background technique [0002] The stratospheric airship is a new type of near-space multi-functional flight platform developed with the continuous development of science and technology. It is different from airplanes and low-altitude airships flying in the aviation layer, and it is also different from satellites working in low orbits. It has a very wide range of military and civilian values, such as missile defense, anti-terrorism, communications, remote sensing, space observation and atmospheric measurement. and so on have great application value. However, the flying height of stratospheric airships is generally around 20km. The air in this area is thin, the density is about 1 / 14 of the surface air density, the atmospheric pressure is about 5.5kPa, the average wind speed is 10m / s, and the maximum wind speed can reach 40m / s. Mainly UV-B, its spectral rang...

Problems solved by technology

The multi-layers of the existing stratospheric airship skin usually use hot-melt coating technology or the way of coating rollers or the way of film bonding to achieve mutual bonding, but because the thickness of each layer of film is generally very thin , so the precision requirements for the above-mentioned processes are very high, but defects such as air bubbles or wrinkles often inevitably appear, which also have an adverse effect on the performance of the manufactured stratospheric airship skin
