Three-channel water surface composite yacht

Abstract

The invention discloses a three-channel water surface composite yacht which comprises a main yacht body. Side bodies are arranged on the two sides of the bottom of the main yacht body respectively. Two middle yacht bodies are arranged between the two side bodies. Three channels are formed between the two side bodies and the two middle yacht bodies. Hydrofoil systems are arranged at the front ends or the rear ends of the three channels. Each hydrofoil system comprises a hydrofoil, a rotating rod and a control device, wherein the rotating rod penetrates through the hydrofoil, the rotating rod drives the hydrofoil to rotate, the control device is installed on the corresponding middle yacht body and connected with the hydrofoil through the rotating rod, and the hydrofoil is driven by the control device to rotate. According to the three-channel water surface composite yacht, through the combination of the good layout characteristic, good resistance performance and high shipping-direction stability of a three-channel skimming yacht and the rapidness and good comprehensive navigation performance of a hydrofoil yacht with controllable hydrofoils, the inherent defects of the three-channel skimming yacht and the hydrofoil yacht are well overcome.

Description

Technical field [0001] The invention relates to a three-channel water surface composite speedboat, which belongs to the technical field of high-performance ships. Background technique [0002] Channel-type planing boats and hydrofoil boats are important members of the high-performance boat family, and a lot of research is currently being carried out at home and abroad. When the channel-type planing boat is sailing at high speed on the water surface, due to the existence of the channel, the air enters the channel opening at the bow of the channel-type planing boat under the action of ramming, and mixes with the splashing water in the channel to form an air-water mixture. As the speed of the hull increases, the amount of air entering the channel opening also increases, thus forming an air layer. Because the density of air or air-water mixture is smaller than that of water, the air layer can be used as a lubricating layer for the lubrication and resistance reduction of the sliding ...

AI Technical Summary

Problems solved by technology

The high-speed sailing of the hydrofoil boat relies on the water lift generated by the hydrofoil to completely lift the hull out of the water. Under the same displacement and propulsion power, its speed is more than 15% higher than that of the planing boat. It overcomes many shortcomings of the planing boat. , but it stalls a lot in waves, and the propulsion device is relatively complicated and expensive
