Hovercraft without lift fan

Abstract

The invention aims at providing a hovercraft. The hovercraft comprises a ship hull and a ship power device, wherein the ship hull comprises a main ship hull and two sub-ship hulls; and the bottom surface of each sub-ship hull is lower than that of the main ship hull. The two sub-ship hulls are symmetrically arranged below the front part of the bottom surface of the main ship hull in parallel, and an interval is formed between the two sub-ship hulls. The outer side surfaces of the sub-ship hulls and the outer side surface of the main ship hull are aligned or are of the same side surface, and the aligned side surfaces or the same side surface extend / extends to the lower parts of the bottom surfaces of the main ship hull and the sub-ship hulls for constituting a main side wall. The inner side surfaces of the sub-ship hulls extend to the lower parts of the bottom surfaces of the sub-ship hulls for constituting sub-side walls. During navigation of the hovercraft, the main side wall and the sub-side walls are partially inserted into water and jointly form three lift spaces which are independent respectively and open forwards with the bottom surfaces of the main ship hull and the two sub-ship hulls respectively. The hovercraft eliminates the lift fan of the traditional hovercraft, but a high-pressure air cushion can be effectively formed at the bottom parts of the ship hulls during the navigation; and the hovercraft further has the advantages of small navigation resistance, high propulsion efficiency and high navigation speed.

Description

technical field [0001] The invention relates to a ship or other water craft, which is a high-speed ship with small sailing resistance, high propulsion efficiency, and fast sailing speed, and a fanless hovercraft with better stability, larger load, and lower energy consumption. Background technique [0002] The traditional hovercraft mainly relies on the effect of pad lift fans to form a high-pressure air cushion at the bottom of the ship, lifting the hull above the water surface, which greatly reduces the resistance of the water during navigation. It not only has high sailing speed, but also has good adaptability. And sailing drive device, the traditional hovercraft needs to consume a large pad lift power when sailing, even accounting for more than 50% of the total power, which makes the traditional hovercraft not only high in cost, but also low in operating economy. Contents of the invention [0003] The object of the present invention is to provide a hovercraft, the uniq...
