There are other six hydraulic cylinders mounted on the control plate of control rod in the positions corresponding to the six turning disc cylinders, and each hydraulic cylinder has helium plug inside connected to the piston in a turning disc cylinder via a dumbbell-shaped rod. A sleeve is mounted on the control rod via bearings and its outside is close to a lens. The airship propeller is economic and reusable, and may be used in aviation and aerospace.
