Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 3, a multipurpose hovercraft for water, land and air comprises a hull 1, wherein at least one first duct 2 is arranged on the hull 1, the first duct 2 is arranged on the hull in a penetrating manner and is perpendicular to the hull, a first rotor 3 is arranged in the first duct 2, the first rotor 3 provides a vertical lift force F1 for the hull, at least one second duct 4 higher than the upper surface of the hull is arranged on the hull 1, the second duct 4 is arranged in an inclined manner with the plane of the hull 1, a second rotor 5 is arranged in the second duct 4 and is used for providing a tilt lift force F2 for the hull, and an air cushion 6 for providing buoyancy is coated on the outer side of the hull.

In addition, the inclination angle between the second duct 4 and the plane of the ship body 1 is 30 degrees, the push ratio of the amphibious air cushion ship is 1 to 1.5, the second duct 4 can provide a vertical component force Fb and a horizontal component force Fa for the ship body 1, and the amphibious air cushion ship can have power for advancing in the horizontal direction and lift force in the vertical direction.
