Embodiment Construction

[0028] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0029] combine Figure 1 to Figure 8 , The present invention aims to provide a supercavitation high-speed ship that utilizes supercavitation technology, has a displacement of 2,000 tons, and can achieve high speed in water (about 50 knots) and sail stably. In order to minimize the external resistance caused by the submerged body itself, its slenderness ratio is generally designed to be between 11 and 21. The submersible body is composed of a three-segment axisymmetric revolving body with a front cone, a middle cylinder and a tail inverted cone. The specific size of the submerged body is determined by the relationship between the lengths of each part of the submersible body, the general rules of the submersible body design and the slenderness ratio of the submersible body.

Abstract

The invention relates to a supercavitation high-speed ship, and belongs to the technical field of high-speed ship application. The supercavitation high-speed ship comprises underwater submerged bodies, a support structure and a ship body. Each underwater submerged body is composed of two rotary bodies, wherein the heads of the rotary bodies are provided with the disc cavitators, and the middle cylindrical sections are provided with the annular cavitators. The support structure is connected with the two underwater submerged bodies and is in lap joint with the ship body. The cross section of theship body is designed into a deep V shape with a small waterline surface, so that the wave-making resistance can be reduced, and the seakeeping of the ship is improved. When the ship body is at a static or low-speed stage, a rotating device is rotated to put down a flat plate, so that the waterline area is increased through the arrangement of the flat plate, and the stability at the static and low-speed movement is maintained. After the ship body reaches a certain speed, the rotating device tightens a steel wire rope to retract the flat plate to be tightly attached to the surface of the shipbody, so that the wave-making resistance and the friction resistance caused by the flat plate are reduced. And meanwhile, through the manual ventilation and the auxiliary effect of the disc cavitators, the middle annular cavitators and the ventilation devices, the supercavitation bubbles are generated to wrap the submerged bodies, and the frictional resistance of the submerged bodies is reduced.

Description

technical field [0001] The invention relates to a supercavitating high-speed ship, which belongs to the technical field of high-speed ship application. Background technique [0002] Because the density of water is much greater than that of air, the resistance of the vehicle when sailing in the water is nearly 850 times that of the air. As a result, the modern ships have the defects of slow speed, short voyage and low precision in the process of sailing. In order to reduce the resistance of the sailing body, there are usually two ideas. The first is to increase the power provided by the engine, and the second is to reduce the resistance during sailing. Due to the limitation of engine power, reducing sailing resistance has become the main way to solve problems such as slow ship speed. [0003] Supercavitation technology is a technology that uses the principle of cavitation to make objects wrapped in cavitation and no longer in direct contact with water, thereby reducing navi...
