Traditional high-speed ships, such as hydrofoil propulsion methods, mainly accelerate the ship to a very high speed by using a propeller installed at the rear of the ship, so that the hydrofoil moves rapidly in the water, and the ^ τK wing generates an upward lift, and the hull Lifting out of the water and sailing this way, although this method of ship propulsion overcomes the resistance to the wave of water generated by a traditional ship during navigation, but because the hydrofoil generates lift, it also generates resistance. In addition, at high speeds, the hydrofoil Cavitation obstacles will also occur. For this reason, it takes a lot of sailing power and energy to lift the hull, especially for large-tonnage hydrofoil boats. It is also technically difficult to increase the area and weight of the hydrofoil. When the speed is low and the navigation channel is complicated, when the hydrofoil cannot travel at high speed, the hydrofoil cannot leave the water surface, which cannot reflect the advantages of the propulsion method.

Vector, where the annual thrust in the horizontal direction generates the horizontal thrust that advances the hull, and the vertical thrust vector generates the thruster that lifts the entire hull off the water surface. The second method of ship propulsion with adjustable power vector direction in this solution is a plurality of symmetrically distributed propeller brackets mounted on the hull to support the hull, and the lower part of the propeller bracket can be rotated upward in the forward direction of the hull. Rotating a certain angle in the angle and the horizontal direction can generate horizontal and vertical thrust vectors of different sizes, in which the horizontal thrust vector generates the horizontal thrust of the hull forward and can make the horizontal thrust vector form a certain angle with the hull travel direction, vertical direction Thrust Yado is a thruster that produces a vertical thrust that shoots the entire hull off the water.

The present invention is a ship propulsion method for lifting the hull off the water surface to obtain less water surface resistance and higher power efficiency during sailing. The effect is to install the propeller bracket mounted on the hull and the lower part of the propeller bracket. It can be achieved by a thruster that can rotate a certain angle in the forward direction of the hull to generate horizontal and vertical thrust vectors of different sizes. When sailing, the thrust vector of the thruster and the horizontal direction of the sail have an upward angle. The propulsive force in the direction pushes the ship forward, and the propulsion force in the vertical direction only lifts off the water. This method of shed can only make the hull not contact the water surface during sailing, so it has good hydrodynamic performance, which greatly reduces the water resistance, especially the wave resistance, while the ship is less affected by the wind and waves. No hydrofoil is used, which overcomes the various resistances generated when the hydrofoil moves in the water, and the boat can be left off the water surface at low speeds. At the same time, the method of the present invention can be made into a combination type, which can be increased or decreased as required. For small boats and large ships (such as aircraft carriers), this is currently unreachable for hydrofoil ships. In special extreme cases, when the present invention adjusts the propulsive force to vertically downward, the water hovering of the ship can be achieved. This is also a special effect of the present invention, which cannot be achieved by some high-speed ships such as hydrofoil boats at present. It meets the requirements of some special environments, such as heavy wind and waves, and requires the ship to be stable. In addition, the invention can easily adjust the horizontal and vertical forces through an automatic control system to maintain the stability and speed of the ship, and the direction of the horizontal force vector can be balanced. The ship is affected by lateral pressure and current and can turn the ship.
