Hydrofoil boat with multi-layered hydrofoil configuration

Abstract

The invention discloses a hydrofoil boat with multi-layered hydrofoil configuration, including a hydrofoil boat body, wherein the hydrofoil boat body comprises a water boat and first hydrofoil platesarranged on both sides of the water boat, wherein the bottom of the first hydrofoil plate is provided with a second hydrofoil plate; a support rod is arranged on the second hydrofoil plate; a supportrod is rotatably connected with a support column of the hydrofoil boat connected with the corresponding first hydrofoil plate; the first hydrofoil plate is internally provided with a driving mechanismfor driving the support rod to rotate, and the driving mechanism is connected with a console in the hydrofoil boat; the front part of the second hydrofoil plate is provided with a baffle plate, and the rear part is provided with a directional tower; the directional tower is connected with a driving device arranged in the second hydrofoil plate; and the driving device is connected with the console. The hydrofoil boat with multi-layered hydrofoil configuration is novel in design and simple and reasonable in structure. By changing the direction of water flow through the second hydrofoil plate, not only the speed of the hydrofoil boat can be increased, but also the buoyancy of the hydrofoil boat can be increased by the second hydrofoil plate, so as to increase the sailing speed of the hydrofoil boat.

Description

technical field [0001] The invention relates to the field of hydrofoil boats, in particular to a hydrofoil boat with a multilayer hydrofoil structure. Background technique [0002] The fully submerged hydrofoil boat is a new type of high-performance ship, which has the characteristics of good seakeeping, flexible maneuvering, and low navigation resistance. The principle is that in the fluid, the greater the flow velocity, the lower the pressure. When the hydrofoil boat sails at high speed in the water, the upper surface of the hydrofoil of the hydrofoil boat is raised, and the water velocity between the hydrofoil and the hull is high, and the pressure is high. Small, the water flow velocity on the lower surface is small, and the pressure is strong, so there is an upward pressure difference between the upper and lower surfaces of the hydrofoil. During navigation, the dynamic lift of the fully submerged hydrofoil boat bears part of the still water buoyancy, and the hull is rai...

AI Technical Summary

Problems solved by technology

[0003] When the fully submerged hydrofoil boat sails, its self-stability is poor, and certain control devices and auxiliary equipment are needed to control its motion attitude. Poor performance, its roll is relatively severe; when turning at high speed, its radius of gyration and heel angle will increase accordingly, which has an adverse effect on the maneuverability, seaworthiness and safety of the ship

[0004] After searching the existing technologies, it is found that in the current research on fully submerged hydrofoil boats, some of its airfoils are modified (such as by changing the angle of attack of the hydrofoil), and some of its propulsion devices are optimized (such as by adding engine), but generally only controls the longitudinal motion, but does not improve the roll and slew performance
