  • Gas-proof fastening system for a non-rigid airship
    Patent number: 4432513
    Abstract: A gas leak proof sealing panel system is disclosed for a non-rigid airship such as a gas balloon. The sealing panel system is especially useful as a rip panel for rapid deflation of the airship. The rip panel covers an aperture in an envelope of the airship and is held in position by hook-loop releasable fastening type strips. Grease is applied to at least one of the strips such that when they are aligned and mated, a gas leak proof seal is formed.
