A retractable landing craft embedded in an air cushion

Abstract

The invention relates to a landing craft with an embedded and retractable air cushion. The landing craft with the embedded and retractable air cushion is characterized in that the landing craft comprises a main craft body, a craft body superstructure, an embedded and retractable airbag cabin, water jet propulsion devices and vector air propeller devices; when hover draught fans work, a part of airflows to an airbag through a telescopic pipe, then flows into a corresponding pressurizing branch room through flow dividing cabin doors, and finally enters an air cushion cabin through a plurality of openings formed in the bottoms of the pressurizing branch rooms to form an air cushion; and a part of air flows directly to the pressurizing branch rooms through the telescopic pipe, and then entersthe air cushion cabin through the openings formed in the bottoms of the pressurizing branch rooms to form the air cushion. When the pressure intensity in the airbag reaches a certain value, a craft body is supported by the air cushion, the craft body is made to separate away from the water surface by the air cushion, and the resistance is greatly reduced; and at the same time, the landing craft has the ability of walking on a road, when the pressure in the airbag reaches a design value, the craft body is separated away from the water surface to form the air cushion, and air propellers on therear parts of connecting axles can provide power and steering in the horizontal direction. According to the navigation mode, human and material resources can be transported to a specified region in ashort time.

Description

technical field [0001] The invention relates to the technical field of high-performance hybrid ships, in particular to a retractable landing craft embedded with an air cushion. Background technique [0002] Catamaran: It has a large deck area and space, and at the same time can easily obtain a higher speed. Each hull is thinner and longer, thereby reducing the wave-making resistance at high speed, so that it can be more convenient to obtain a higher speed. Speed ​​requirements. Since the width of the catamaran is much larger than that of the monohull, its lateral stability is obviously better than that of the monohull, and it has the ability to withstand relatively large wind and waves; the catamaran not only has good maneuverability, but also has a resistance peak Compared with monohull ships of the same tonnage, the catamaran has a larger overall width, so it often has a larger deck area and cabin volume, especially suitable for loading those ships that are large in size ...

AI Technical Summary

Problems solved by technology

The function of the air cushion greatly reduces the movement resistance, increases the speed of the ship, and increases the speed of the ship. However, after the compressed air is sprayed out, it escapes to the surroundings, causing quite large waves and splashing a lot of water, which consumes a lot energy

Therefore, although the speed of the ship has increased, the horsepower required is also very large.

At the same time, the hovercraft has poor seakeeping performance, a large stall in sailing in wind and waves, and poor maneuverability
