Abstract

The invention discloses a hydrofoil ship with a self-adaptive hydrofoil attack angle, which comprises a ship body, a support frame and a plurality of hydrofoils, wherein the support frame is fixedly arranged at the bottom of the ship body, the hydrofoils are distributed along the length direction of the ship body, the hydrofoils are eccentrically and rotatably arranged at the bottom end of the support frame at a limited angle, and when the hydrofoils are positioned at an initial position, the connection position of the hydrofoils and the support frame is positioned between the center of the end face of the hydrofoils and the bow of the ship. In the hydrofoil ship with the self-adaptive adjustment of the hydrofoil attack angle, the hydrofoil is eccentrically arranged at the bottom end of the supporting frame in a rotating way at a limited angle, so that the hydrofoil can be driven by the water wave to passively and adaptively adjust the attack angle.

Description

Hydrofoil ship with hydrofoil attack angle capable of being adaptively adjusted Technical Field The invention relates to the technical field of hydrofoil vessels, in particular to a hydrofoil vessel with a self-adaptive hydrofoil attack angle. Background A hydrofoil vessel is a vessel which can lift the hull by means of the pressure difference between the upper and lower parts of the hydrofoil, thereby achieving rapid sailing. Since the advent of hydrofoil vessels, a wide range of international navigation has been drawn, and the hydrofoil vessels have been under continuous investigation as part of high-tech, high-performance, high-tip sports. Patent application number 202211318063.2 discloses a hydrofoil game angling boat with adjustable attack angle, in the scheme, the attack angle of a hydrofoil is adjusted by a self-adaptive attack angle control system, the adjustment step is that an attitude sensor is used for obtaining the heave condition of a boat body, a controller determines the change condition of the hydrofoil attack angle according to the heave condition of the boat body, and an actuator controls a first motor and a second motor to adjust the expansion and contraction amounts of a first telescopic shaft and a second telescopic shaft according to the change condition of the hydrofoil attack angle so as to realize the increase/decrease of the hydrofoil attack angle. In the above scheme, the hydrofoil attack angle is actively regulated through motor driving, and because the active regulation has hysteresis (the regulation of the hydrofoil attack angle is after the ship body is heave), under the influence of waves, the effect of lowering the navigational speed, tilting the attitude and the like of the hydrofoil ship can be caused, and even the risk of capsizing can be caused, so that improvement is needed to improve the wave resistance of the hydrofoil ship. Disclosure of Invention The invention aims to overcome the defects of the prior art, and provides a hydrofoil ship with an adaptively adjustable hydrofoil attack angle, which solves the technical problems that the hydrofoil attack angle adjusting mode of a hydrofoil game angling boat with an adjustable attack angle in the prior art is active adjustment, and due to hysteresis of the active adjusting mode, the effect of lowering the navigational speed, tilting the posture and the like of the hydrofoil ship can be caused under the influence of waves, and even the risk of capsizing can be caused.
