[0002] A hovercraft is a high-speed ship that utilizes the surface effect principle and relies on air above atmospheric pressure to form an air cushion between the hull and the support surface, enabling the hull to completely or partially separate from the support surface for navigation;

[0003] Among them, the lifting device of the hovercraft is an important part for realizing the suspension, lifting and stable navigation of the hovercraft on water, ground or in the air. Its lifting device mainly includes components such as an air cushion chamber, a guide vane, an air pump, etc., as well as a jet engine to control the formation of the air cushion and the lifting of the hull;
