High-speed catamaran

Abstract

The invention provides a high-speed catamaran which comprises two sheet bodies arranged in parallel and a main cabin connected onto the tops of the sheet bodies. The high-speed catamaran further comprises two bulbnoses, an air suction device and a plurality of micro-bubble generating devices, wherein the two bulbnoses are connected to the bottom of the main cabin through struts and are vertically arranged on a bow and a stern of the catamaran, the air suction device is mounted on the top of the main cabin and is communicated with air pipes arranged inside the high-speed catamaran in a built-in mode, and the plurality of micro-bubble generating devices are arranged on the surfaces of the bulbnoses and the sheet bodies and is communicated with the air pipes. Hydrofoils are symmetrically arranged on both sides of each of the bulbnoses. The seakeeping performance of the catamaran is enhanced by arranging the bulbnoses with the hydrofoils on the bow and the stern to reduce wave-making resistance. The micro-bubble generating devices arranged at the bottom of the catamaran can generate thin bubble films at the bottom of the catamaran to reduce the frictional resistance of the catamaran. The air suction device arranged on the top of the cabin and air suction rotors can further improve the air suction efficiency of the air suction device, enhance the resistance reduction effect of the micro-bubble generating devices, and greatly reduce the energy consumption for generating micro bubbles.

Description

technical field [0001] The invention relates to the technical field of ships and ship-related equipment, in particular to a high-speed energy-saving catamaran. Background technique [0002] In recent years, international trade has grown much faster than our road infrastructure has expanded, further increasing the pressure on already congested road transport. The existing land road infrastructure can no longer meet the growing demand, and the expansion of land road infrastructure has the characteristics of high cost, which makes the continuous expansion of the existing road infrastructure cause many disputes. [0003] In response to the urgent need to expand maritime transportation, the United States, Japan and European countries have actively developed maritime highway systems and designed a series of high-performance ships. Among them, the more famous ones are the series of wave-piercing catamarans (WPC) designed by INCAT, the multi-pod propulsion non-ballasted watercraft ...

AI Technical Summary

Problems solved by technology

The micro-bubble drag reduction technology under research can effectively reduce the frictional resistance of ships by generating a layer of micro-bubble film on the surface of the hull, which has certain prospects, but the process of generating micro-bubbles consumes a lot of energy
