AIRSHIP, METHOD FOR DETACHING LID MEMBER OF AIRSHIP, AND METHOD FOR REPLACING LID MEMBER OF AIRSHIP

摘要

PROBLEM TO BE SOLVED: To detach and replace a lid member while maintaining the air ship hull shape without discharging a gas filled in the hull of an air ship.;SOLUTION: A cylindrical membrane 50 is joined with a hull skin so as to accommodate a lid member 30 in an opening of the cylindrical membrane 50. An arm A is inserted in the cylindrical membrane 50, a space between the cylindrical membrane 50 and the arm A is covered with a rope R, and the lid member 30 is detached from a hull by using a screw driver D. The detached lid member 30 is separated from a hole part, and leakage of a gas in the hull is prevented by binding a specified portion of the cylindrical membrane 50 (a portion between the lid member 30 and the hole part), and the lid member 30 is taken outside the cylindrical membrane 50. Thereafter, a new lid member and a new arm are inserted in the cylindrical membrane 50 to cover a space between the cylindrical membrane 50 and the arm, the specified portion of the cylindrical membrane 50 is unbound, and a new lid member is attached to the hull by the screw driver.;COPYRIGHT: (C)2007,JPO&INPIT
