AIR-SAC STRUCTURE ENHANCING DISCHARGE OF GAS

摘要

PURPOSE: An envelope structure is provided to prevent the movement of gas due to the attachment of the inner wall of an envelope by forming a gas guide unit inside the envelope such as a balloon, an airship, or a tube. CONSTITUTION: An envelope structure(200) comprises a gas storage unit(110) and a gas guide unit(120). The gas storage unit is formed inside the envelope structure. The gas guide unit is integrated with the inner surface of the envelope and has fixed thickness to prevent inner surfaces of the envelope from contacting each other. The gas flows in the gas guide unit. The gas guide unit comprises multiple discharge holes. A discharge path is formed inside the gas guide unit and guides the gas inside the gas storage unit along to the gas guide unit.
