Abstract: An airship comprising an envelope having a shape, a volume, and a frontal area. A lifting gas within the envelope. A propulsion system. A volume change mechanism arranged to change the shape of the envelope, wherein the change in shape of the envelope changes the volume of the envelope, the change in volume of the envelope causes a change in the buoyancy of the airship, and the change in shape of the envelope causes the frontal area of the envelope to change proportionally to the change in volume of the envelope.
