Three-controllable hydrofoil displacement boat

A technology of planing boats and hydrofoils, which is applied to ships, uses hydrofoils to act on the surrounding water surface to reduce ship motion, and water to act on propulsion components. It can solve problems such as additional resistance of appendages, reduce appendage parts, and reduce power loss. , the effect of increasing the speed

Problems solved by technology

Although the appendage can provide more gliding surfaces when the hull is gliding, the additional resistance of the appendage is a questionable issue when the gliding boat does not enter the gliding stage

[0017] (a) Implementation of three-controllable hydrofoil planing craft

[0018] The three-controllable hydrofoil planing boat is mainly composed of two main hydrofoils 3 at the rear of the ship and an auxiliary hydrofoil 4 at the bow. The main hydrofoil system on the side of the rear part of the ship is composed of the main hydrofoil 3, the hydraulic rotating device 1, and the main hydrofoil linkage 2, such as figure 1 shown. Wherein the planing boat is designed with a concave position 10 at the side of the ship, the concave position 10 of the side of the ship just places the main hydrofoil 3, and the corresponding position of the bottom of the ship is designed with a break level 9, such as figure 2 shown. The main hydrofoil system realizes the position conversion under the rotation degree of freedom through the hydraulic device, such as image 3 shown. The first position is the stowed state, and the planing boat has not entered the planing state. The second position is...

Abstract

The invention relates to a three-controllable hydrofoil displacement boat which is a high-efficiency energy-saving displacement boat with high performance and is characterized by comprising two main hydrofoil systems, an assistant hydrofoil system, a hydraulic control system, recesses on the side of the boat and steps on the bottom of the boat. The side of the boat on the middle back part of a boat body has the recesses; regulable main hydrofoils are installed; the positions of the main hydrofoils can be changed by a hydraulic device; an assistant regulable hydrofoil is arranged on the front segment of the boat body; and the hydraulic control system is used for controlling the cooperative action of the two main hydrofoils and the assistant hydrofoil for regulating the navigating postures of the displacement boat and improving moving performance, comprising longitudinal swing, transverse swing, vertical sway, lateral movement and the like of the displacement boat. The main hydrofoils are shallow immersion hydrofoils and have a certain self-stability, simple structure and lower cost.

Description

technical field [0001] The invention is applied in the field of high-performance boat manufacturing, specifically a three-controllable hydrofoil planing boat. Background technique [0002] The excellent hydrodynamic performance of the planing boat makes it widely used in small boats, such as patrol boats, fishing boats, service boats, ambulance boats, entertainment boats and sports boats. When the planing boat is in the gliding state, the structure at the bottom of the stern serves as the main gliding surface to provide the dynamic lift of the hull, and the lifting of the hull reduces the wet surface area, reduces the frictional resistance, and increases the speed accordingly. Therefore, many planing boats add appendages to the rear to increase the sliding area and then lift the hull, reduce resistance and increase speed. Although the appendage can provide more gliding surfaces when the hull is sliding, the additional resistance of the appendage is debatable when the planin...
