specific Embodiment approach

[0020] Develop the layout and technology of new supercavitating water surface high-speed boats according to the set specific ship shape dimensions (such as length: 20 meters, width: 12 meters, draft: 2.5 meters) and sailing speed (such as 80-100 knots) indicators design. The specific implementation is as follows:

[0021] Ship type composition for the new supercavitating surface high-speed craft:

[0022] The underwater submerged body is designed, and the length of the underwater submerged body is given according to the resistance of the new supercavitating surface high-speed boat when it sails in supercavitation, the shape of the cavitation, and the buoyancy generated when it is sailing in a non-supercavitating state and when it is still. , maximum diameter and cavitator diameter. Considering the stability of sailing, set the fin stabilizer and rudder.

[0023] The support structure is designed, and the water-facing surface is designed to be streamlined, and the internal c...

Abstract

The invention discloses a novel supercavitation water surface high-speed boat. The novel supercavitation water surface high-speed boat comprises submerged bodies 23, a support structure, a turbojet engine 8, a driver cabin 5, a steward cabin 4, an S air inlet channel 7, a tail flame treatment nozzle 9, a power source system 1, a central control system 6, an air filter device 2, an air compressionsystem 3 and cavitation generators. The cavitation generators each comprise a cavitator 10, air guiding bushings 13, exhaust holes 14 and air leading grooves 16. Air enters a hull from the air filterdevice 2 and enters the turbojet engine 8 through the S air inlet channel 7 and is finally ejected out through the tail flame treatment nozzle 9. The novel supercavitation water surface high-speed boat takes the turbojet technology as propulsion power, so that compared with an underwater propeller, the propulsion speed and the efficiency are higher; the cavitation generators adopt the supercavitation technology, so that the hull does not make direct contact with water, compared with a traditional vessel, the water resistance of the hull can be reduced, and the navigational speed is increased.

Description

technical field [0001] The invention belongs to the technical field of ship application, and in particular relates to a novel supercavitating water surface high-speed boat. Background technique [0002] The main engines of modern transport ships are mainly diesel engines. After continuous improvement, diesel engine power devices are becoming more and more perfect. Therefore, they have become the most widely used ship power devices and have an absolute advantage in quantity. The propeller connected to the power unit of the ship is usually a propeller, which can make the ship move forward or backward when the propeller rotates in the water. However, the resistance of the moving body in the water is about 850 times the resistance in the air. Therefore, the conventional power unit in the water It is difficult for the underwater speed to exceed 35m / s, which leads to the common defects of slow speed, short voyage and low precision in traditional underwater vehicles. When the prop...
