When lighter-than-air gas compressed and filled in a pressure-resistant container is injected into an envelope, buoyancy created in the envelope causes an aircraft to ascend. When the aircraft finishes its flight role, a lid of an opening/closing mechanism is opened to exhaust from a port lighter-than-air gas from the envelope. When the buoyancy of the envelope is insufficient to counter the weight of the aircraft, the aircraft begins to descend. The lid of the opening/closing mechanism is closed on the port, and exhaust of lighter-than-air gas from the envelope stops. After the aircraft reaches a surface of land or water, an operator connects a duct to a gas suction device. The gas suction device collects the lighter-than-air gas remaining in the air sac into a container. The lighter-than-air gas collected into the container is transported to a gas collection facility, compressed by a compressor, and filled into a pressure-resistant container.
A method of reusing a lighter-than-air gas used for an aircraft that ascends under buoyancy generated by the lighter-than-air gas contained in an envelope of the aircraft, comprising:
