specific Embodiment approach

[0017] Carry out the layout and technical design of the supercavitating surface high-speed craft according to the set specific ship outline dimensions (such as length: 20 meters, width: 12 meters, draft: 2.5 meters), and sailing speed (such as 80-100 knots) . The specific implementation is as follows:

[0018] The structure of the supercavitating surface high-speed craft:

[0019] The underwater submersible body is designed, according to the resistance of the supercavitation surface high-speed boat during supercavitation navigation, the shape of the cavitation, and the buoyancy generated when the non-supercavitation state sails and is stationary, the length of the underwater submersible body, Maximum diameter and cavitation diameter. Considering the stability of sailing, set fins and rudders.

[0020] The support structure is designed, the upstream surface is designed to be streamlined, and the inner cavity is convenient for the pipeline of the superstructure to pass to the...

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 applications, and in particular relates to a supercavitating water surface high-speed boat. Background technique [0002] The main engine of modern transport ships is mainly diesel engines. After continuous improvement, the diesel engine power plant has become more and more perfect, so it has become the most widely used ship power plant at present, and it has an absolute advantage in quantity. The propeller connected to the power plant of the ship is usually a propeller, which can make the ship move forward or backward when it rotates in the water. However, the resistance of the moving body in water is about 850 times that of the resistance in the air. Therefore, the conventional power plant is used in water. The low speed is difficult to exceed 35m / s, which leads to the defects of slow speed, short range and low precision in traditional underwater vehicles. When the propeller exceeds the optimal sp...
