Embodiment Construction

[0030] The specific structure and implementation process of this solution will be described in detail below through specific embodiments and accompanying drawings.

[0031] like figure 1 , 2 As shown, in one embodiment of the present invention, a super-high-speed water surface vehicle 100 based on a three-stage supercavitating hydrofoil is disclosed, which includes a ship body 1 of a round bilge type, and is installed on both sides of the front of the ship body 1 respectively. There are two symmetrical front hydrofoils 2, and the front hydrofoils 2 are connected to the main body 1 of the ship at a distance of one-third from the front end, and are close to the upper edge of the main body 1 of the ship; Horizontal flat wing 21, the oblique wing 22 that is connected to the other end of the flat wing 21 by one end and inclined to the ship main body 1 direction, and the vertical wing 23 that is connected to the other end of the oblique wing 22 and is perpendicular to the horizonta...

Abstract

The invention provides an ultra-high-speed water surface vehicle based on a three-stage supercavitation hydrofoil, which includes a main body of a ship. Front hydrofoils and rear hydrofoils are respectively installed on both sides of the main body of the ship. Horizontal flat wing, oblique wing connected to the flat wing and inclined towards the main body of the ship, vertical wing connected to the oblique wing and perpendicular to the horizontal plane, wherein the vertical wing is located under the bottom of the main body of the ship; but the span length of the flat wing of the rear hydrofoil is greater than that of the front hydrofoil The length of the flat wing span of the wing; two jet engines are installed side by side on the main body of the ship between the two rear hydrofoils, and a semi-submerged oar is installed at the stern of the main body of the ship. The invention adopts the combined propulsion mode of semi-submerged propeller and turbojet engine, which can provide strong thrust for water surface vehicles under different working requirements, and adopts supercavitation airfoil to reduce the resistance of front hydrofoil and rear hydrofoil. The three-stage hydrofoil structure helps to reduce the sensitivity of the speed and effectively improve the stability of the navigation.

Description

technical field [0001] The invention relates to the field of ships, in particular to an ultra-high-speed water surface vehicle using a novel supercavitating airfoil as a lift component and based on a three-stage supercavitating hydrofoil. Background technique [0002] According to the law of ship resistance, the viscous resistance of a ship is proportional to the square of the speed, and the wave-making resistance is proportional to the sixth power of the speed. This means that the higher the speed, the greater the resistance to overcome. Furthermore, sailing resistance is closely related to the wetted surface area of ​​the vessel submerged below the water surface. The surface vehicle lifts the hull through the lift generated by the hydrofoil during navigation, reducing the wet surface area, thereby reducing viscous resistance and wave resistance, and has unique advantages in terms of speed and seaworthiness. [0003] At present, in terms of increasing the speed of the shi...
