Hydrofoil strut and deep-immersed hydrofoil vessel Technical Field The application relates to the technical field of ship engineering, in particular to a hydrofoil strut and a deep-immersed hydrofoil. Background From the law of resistance of the ship, it is known that the viscous drag is approximately proportional to the square of the speed, while the wave-making drag is approximately proportional to the 6 th power of the speed. How to reduce the resistance of the ship and how to reduce the wave making resistance of the ship sailing at high speed are one of the main tasks of shipmakers. The hydrofoil vessel has significant advantages in this respect, when the vessel is sailing, the lift provided by the hydrofoils lifts the hull out of the water, so that the hull is clear of the water, its wave-making resistance is eliminated, and only the hydrofoil strut or hydrofoil is in contact with the water, so that the total resistance of the vessel at high speed is greatly reduced. For deep submerged hydrofoils, depending on the type of hydrofoil structure, the hydrofoil can be studied as a beam with a rigidly fixed upper end of the strut. The support column is subjected to pressure caused by the stress of the bearing plane, and lateral force of water flow reaction force when the ship rotates and is subjected to strong gusts is also applied. Therefore, the thickness of the hydrofoil is increased as much as possible in order to ensure that the strut has sufficient rigidity to resist the bending moment of the lateral force.
