The invention provides a retractable airship air bag and a manufacturing method of the retractable airship air bag. The manufacturing method is characterized by including the following steps of firstly, installing an air bag stretch-out and draw-back device in the air bag; secondly, installing a time control system above the air bag stretch-out and draw-back device; thirdly, connecting the time control system with the air bag stretch-out and draw-back device; fourthly, installing a time control system in the air bag, wherein the time is counted while the air pressure rises, and when the air pressure rises to a certain value, the air bag can be axially shortened through the air bag stretch-out and draw-back device, and the volume inside the air bag accordingly increases. The retractable airship air bag and the manufacturing method have the advantages that due to the fact that the air bag is provided with the air bag stretch-out and draw-back device used for axially stretching out and drawing back the air bag, when an airship climbs to a high place and the relative pressure in the air bag is increased, the air bag can be axially shortened through the air bag stretch-out and draw-back device, the volume in the air bag is accordingly increased, the tension of the bag cover of the air bag is reduced, the aim of protecting the bag cover against damage can be achieved, the air bag can keep the pneumatic appearance of the appropriate rigidity, and the flight is facilitated.
