Abstract

The invention discloses a capsule material composite layer and an aerostat. The capsule material composite layer comprises a metamaterial layer used as a frequency selection surface. By providing the capsule material composite layer comprising the metamaterial layer as the frequency selection surface, and utilizing the characteristic that the probability of detecting the metamaterial layer by a radio detection device is extremely low, the capsule made of the capsule material composite layer has the radar stealth function.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a capsule material composite layer and an aerostat. Background technique [0002] An aerostat or airship is an aircraft that mainly relies on air buoyancy (or static lift) to overcome its own gravity to stay in the air or fly. Its main body is a capsule that is filled with buoyant gas and has good airtightness. Therefore, for aerostats or airships, the performance of the capsule directly determines the success or failure of its mission, the load capacity and the flight cost. [0003] The capsule body material (also known as the skin material) is the main structural material of the capsule body, which plays a role in maintaining helium and providing buoyancy. The capsule material is generally composed of high-strength, light-weight and high-gas-barrier polymer composite materials. For example, the Chinese patent with publication number CN102416739A discloses an airship skin m...
