The invention relates to a self-adaptive hydrofoil ship with an adjustable span-chord ratio of hydrofoils, and belongs to the technical field of hydrofoil ships. The hydrofoil ship comprises a hydrofoil ship body, a hydrofoil ship gravity center is arranged on the hydrofoil ship body, a rear hydrofoil assembly is arranged at the tail of the hydrofoil ship body, and a front hydrofoil assembly is arranged at the head of the hydrofoil ship body; a self-adaptive assembly is arranged on one side of the gravity center of the hydrofoil ship, and the self-adaptive assembly structurally comprises a pitching control assembly, a self-adaptive control valve correspondingly matched with the pitching control assembly and a hydraulic oil supply system connected with the self-adaptive control valve. A hydrofoil ship body is provided with a hydrofoil ship control system, and the rear hydrofoil assembly and the front hydrofoil assembly stretch out or retract back through regulation and control of the hydrofoil ship control system. The self-adaptive adjustment change of the positive and negative attack angles of the front and rear hydrofoils can enable the front and rear hydrofoils to produce hydrodynamic lift force or pressure opposite to the pitching direction, so that the hydrofoil ship can meet the use requirements under different wave heights through the adjustment and matching of the optimal hydrodynamic lift force positive attack angles of the front and rear hydrofoils.
本发明涉及一种水翼展弦比可调的自适应水翼船,属于水翼船的技术领域。它包括水翼船船体,水翼船船体上具有水翼船重心,在水翼船船体尾部设置后水翼组件,在水翼船船体头部设置前水翼组件;在水翼船重心的一侧设置自适应组件,自适应组件的结构为:包括纵摇控制组件,与纵摇控制组件相对应匹配有自适应控制阀,还包括与自适应控制阀相接的液压供油系统;在水翼船船体上设置水翼船控制系统,后水翼组件和前水翼组件经水翼船控制系统的调控进行伸出或缩回动作。本发明的前后水翼正负攻角的自适应调节变化,能使前后水翼生产与纵摇方向相反的水动升力或压力,从而通过前后水翼最佳水动升力正攻角的调节和匹配,使水翼船满足不同波高下的使用要求。
