description The utility model relates to a lifting device of air power, which relates to a mechanical component generating lift force by rotating, particularly a lifting device for a helicopter. The utility model is mainly composed of a cylinder joint, a component 1 provided with an umbrella-shaped rotating surface and a component 2 which is positioned below the component 1 and provided with a rotating surface similar to the umbrella-shaped rotating surface of the component 1, and a definite clearance is maintained between the component 1 and the component 2. A plurality of holes are spread over and arranged on the umbrella-shaped rotating surface of the component 1, and the cylinder joint is arranged on the top center position of the umbrella-shaped rotating surface of the component 1. When the utility model is rotated at high speed, formed pressure difference is large, active area is large, and greater lift force can be generated.
