An airship in which a floating helium gas chamber (1) and an accumulating helium gas chamber (2) are connected together by a control unit (7) having an electromagnetic valve (5A), a compressor (4) and a cooler (3), and a control unit (9) having an electromagnetic valve (5B) and a temperature controller (6). In order to fly the airship upward, the helium gas is supplied from the accumulating helium gas chamber (2) to the floating helium gas chamber (1) by operating the control unit (9) to increase the volume of the floating helium gas chamber (1). In order to fly the airship downward, the helium gas is returned from the floating helium gas chamber (1) to the accumulating helium gas chamber (2) by operating the control unit (7) to reduce the volume of the floating helium gas chamber (1). The altitude of the airship can be maintained automatically at a predetermined level by operating both of the control units (7), (9) in accordance with a signal from an altitude designating sensor unit (8). |
