Method for production of zeppelins for transporting loads, involves producing large vacuum by pumped-out air from carrying hollow body of airship by on board installed vacuum pumps, where hollow body is filled with gases

摘要

The method involves producing large vacuum by pumped-out air from a carrying hollow body of an airship by on board installed vacuum pumps, where the hollow body is made of composite materials such as glass fibers, carbon fibers or resins. The hollow body is filled with gases such as hydrogen or helium.
