Embodiment 1

[0091] Embodiment 1: The supercavitating hydrofoil boat described in the present invention is composed of components such as a hull, a propulsion propeller, a rudder, a power system inside the hull, and a supercavitation system;

[0092] Its supercavitation system is composed of a high-pressure air pump, an air pipeline, a pipeline air valve, a hollow hydrofoil pillar, and a V-shaped hydrofoil jet assembly (see figure 1 A, B, and C are shown in the picture);

[0093] The outer surface of the hull is a streamlined hull; the pipeline air valve is used to control the air pressure of the V-shaped hydrofoil jet assembly to provide appropriate air intake pressure for various parts of the V-shaped hydrofoil jet assembly;

[0094] Connect the air pipeline, high-pressure air pump, air pipeline, pipeline air valve, air pipeline, hollow hydrofoil pillar, and V-shaped hydrofoil jet assembly in sequence with the air inlet;

[0095] The high-pressure air pump sucks the air above the deck t...

Embodiment 2

[0099] Embodiment two: the difference between this embodiment and embodiment one is that on the basis of its embodiment one, its supercavitation system has increased the gas storage tank; because the ship has increased the gas storage tank, the gas source of its jet The pressure is more stable, the stability of the air layer ejected from the V-shaped air injection groove is higher, and the isolation effect of the air isolation layer is also better, thus forming the second embodiment.

Embodiment 3

[0100] Embodiment 3: This embodiment is on the basis of Embodiment 1 and Embodiment 2. The difference of this embodiment is that one of the gas sources of its high-pressure air pump is from the exhaust gas discharged by the fuel power of the ship, and the exhaust gas emitted by the engine. , introduce the air inlet of the supercavitation system through the transported air pipeline, and use the exhaust gas discharged from the power system as one of the air sources of the air pump. For military ships, this scheme can significantly reduce the ship's Infrared signal characteristics, to achieve a better stealth effect on infrared; thus respectively constitute the third embodiment of the new.

Abstract

The invention discloses a super-cavitation hydrofoil ship. The super-cavitation hydrofoil ship is a hydrofoil ship capable of sailing at an ultra-high speed. The technology of the ship can be appliedto military and civil ultra-high-speed ships. The hydrofoil ship overcomes the defect that an existing hydrofoil ship is low in speed; the hydrofoil ship is characterized in that, on the basis of a conventional hydrofoil ship, a high-air-pressure air layer is additionally arranged between a hydrofoil and a water body by utilizing a unique super-cavitation system, so that the surface of the hydrofoil is only in direct contact with low-density air, the water resistance borne by the hydrofoil ship during sailing is greatly reduced, and the sailing speed of the ship can easily exceed that of a conventional hydrofoil ship of the same magnitude; according to the super-cavitation system of the hydrofoil ship, the structures of all the parts are relatively simple, a conventional hydrofoil ship isrelatively easy to transform, the sailing speed of the hydrofoil ship is greatly increased, and the hydrofoil ship provides a high-speed, rapid and economical water traffic and carrying tool for people.

Description

【Technical field】 [0001] The invention relates to a water transportation tool, which is a hydrofoil boat capable of sailing at super high speed. The technology used by the ship can be applied to both civil super high speed ships and military ships and other super high speed ships. 【Background technique】 [0002] 1. When a conventional hydrofoil boat sails, its hull is lifted out of the water by the hydrofoil, and its hull structure only has direct contact between the hydrofoil and the water body, so that the direct contact area between the hydrofoil boat and the water body is significantly reduced, and the hydrofoil boat is affected. The resistance of the water is also significantly reduced, thereby significantly improving the sailing speed of the hydrofoil boat; however, the hydrofoil of the conventional hydrofoil boat is in direct contact with the water body, and there is still a large contact area between the hydrofoil and the water body. Therefore, the maximum speed of c...
