PROBLEM TO BE SOLVED: To provide an airship capable of increasing flight altitude largely more than that of a conventional airship.
SOLUTION: This airship 10 is formed in a double film structure capable of storing a plurality of gas bags 12 in a skin 20. Gaseous helium is stored in the gas bags 12, and the plurality of gas bags are installed in the axial direction of a body 11. On the body 11, balloonets 13 and 14 are installed at the front and rear sides thereof. Also, blowers 15 and 16 for discharging the air layer between the body 11 and the gas bags 12 to the outside or sucking the outside air and an internal pressure regulating means 18 having a natural discharge port are installed on the body 11. A pressure difference between the inside and outside of the ship is regulated by the internal pressure regulating means 18, and the posture of the body 11 is controlled by the balloonets 13 and 14.
