Problems solved by technology

Although the full lift hovercraft can be landed, the flexible apron around the bottom of the ship is used for beach landing of military targets. The flexible apron is extremely vulnerable to damage from artillery fire. Once the apron is damaged, the high-pressure air leaks out, and the hovercraft can no longer drive. It needs to be replaced. Difficult, long repair time

Abstract

The invention discloses a hovercraft, and relates to the technical field of ship equipment. The hovercraft comprises a ship body provided with a flexible apron, wherein a propeller is transversely arranged at the bottom of the ship body; the propeller is provided with a blade wheel; the blade wheel is welded with a plurality of annular clapboards at axial intervals; each annular clapboard consistsof plates corresponding to the number of blades, and two sides of each plate are welded with the blades; the outer sides of the two ends of each blade are respectively fixed with a circular cover plate with a through hole in the middle part; the two ends of a rotating shaft are closely attached to the outer part of the circular cover plate and are provided with columnar compressed air distribution chamber boxes; the inner end faces of the compressed air distribution chamber boxes penetrate through the through holes of the circular cover plate and are abutted against the end faces of the blades; the inner end surface of each compressed air distribution chamber box is a circular sealing plate; the circular sealing plate is provided with air distribution holes, and each compressed air distribution chamber box is communicated with a compressed air input pipe. Compared with the prior art, the hovercraft is efficient and can also travel on land when the flexible apron is damaged.

Description

technical field [0001] The invention relates to the technical field of water surface ship equipment, in particular to a hovercraft. Background technique [0002] Hovercraft refers to a high-speed ship that uses the principle of surface effect to form an air cushion between the hull and the water surface or the ground by means of air above atmospheric pressure, so that all or part of the hull can sail away from the water surface or bottom surface. According to the way of generating air cushion, it can be divided into two types: full cushion lift hovercraft and side wall hovercraft. The hovercraft is equipped with blowers and light diesel engines or gas turbines to generate air cushions and drive ships forward, and has propellers such as air propellers, water propellers, and water jet propellers. The high-pressure air generated by the blower is sent through the pipeline into the air cushion chamber formed by the flexible apron or rigid side wall around the bottom of the ship ...
