Paddle wheel propulsion hovercraft

Abstract

The invention discloses a paddle wheel propulsion hovercraft. The hovercraft comprises a hovercraft body, a power system, an air-cushion system and a propulsion system, wherein the air-cushion systemcomprises air-cushion fans and apron boards, the propulsion system comprises a pair of paddle wheel propellers, the paddle wheel propellers are symmetrically arranged on transverse two sides in the longitudinal middle of the bottom of the hover craft body, the paddle wheel propellers are arranged on the inner sides of the apron boards, the driving directions of the paddle wheel propellers are thesame as the driving direction of the hovercraft body, the lower edges of the paddle wheel propellers are lower than the lower edges of the apron boards, the paddle wheel propellers are arranged at thebottom of the hovercraft body through a lifting supporting frame, and the heights of the paddle wheel propellers are adjustable. Compared with a traditional full air-cushion hovercraft, the paddle wheel propulsion hovercraft is higher in propelling efficiency, smaller in noise and better in operability and stability.

Description

technical field [0001] The invention relates to the field of improving the propulsion technology of a hovercraft, in particular to a paddle wheel propulsion hovercraft. Background technique [0002] The development history of hovercraft is more than 100 years, but in recent decades, due to the rapid development of peripheral jet flow theory, high-speed diesel engine, gas turbine and the continuous improvement of hovercraft apron technology, the widespread application of hovercraft has become possible. The hovercraft can not only sail close to the water surface, but also drive on land. It does not rely on wheels to contact the ground like a vehicle, nor does it completely fly into the air like an airplane. It can be seen that the hovercraft is a special ship between vehicles, general ships and airplanes, and the hull can jump out of the water completely when sailing. Hovercraft can be divided into two categories according to the structure of the apron, the way of propulsion ...

AI Technical Summary

Problems solved by technology

[0005] (1) The efficiency is very low: the traditional full cushion lift hovercraft can only be propelled by air propellers, which have lower propulsion efficiency than water propellers, especially at low speeds;

[0006] (2) The noise is very loud: when the traditional full-cushion hovercraft is sailing on the sea or on land, the noise from the air-propelled propeller is very loud and deafening, which does not meet the environmental protection requirements;

[0007] (3) Poor maneuverability: The traditional full-cushion hovercraft is difficult to navigate when encountering wind and waves, and it stalls a lot in waves, especially when driving on a land slope, it is more difficult to maneuver, it is almost impossible to maintain the course, and it is easy to drift;

[0008] (4) Poor stability: The traditional full-cushion hovercraft is very unstable when sailing at high speed, and it is prone to burying its head (especially in the wind), and even capsizes under the action of wind and waves, which is a very serious accident hazard.
