PROBLEM TO BE SOLVED: To provide a hydrofoil craft comprising a full-submergence type hydrofoil that does not change its elevation angle nor lose its lift balance, even when the hydrofoil is lifted up.SOLUTION: A hydrofoil craft is provided in which struts are formed by a front position strut 12 and a back position strut 13, upper one end of both struts 12 and 13 being respectively mounted to a slider 15 that is to be slidably attached to a hull 14 of the hydrofoil craft, while the respective other ends being mounted to a hydrofoil 11 to configure a parallel linkage mechanism. The back position strut 13 together with a slider 15 and a crank arm 17 that is pivotally attached to the middle part of the strut 13 configures a Scott Russell straight-line mechanism so that the hydrofoil 11 makes a parallel displacement vertically with keeping a prescribed elevation angle but without changing the center of lift.

    【課題】水中翼を跳ね上げても水中翼の仰角が変化することなく、また揚力バランスが崩れることのない全水没型の水中翼を備えた水中翼船を提供する。【解決手段】ストラッドが前側ストラッド12と後側ストラッド13とで構成され、両ストラッド12及び13は各一端の上端がそれぞれ水中翼船の船体14にスライド可能に取付けられるスライダー15に軸着されると共に、各他端が水中翼11に軸着されて平行リンク機構を構成し、後側ストラッド13が該ストラッド13の中間部に軸着されるクランクアーム13及びスライダー15と共にスコット・ラッセル式直線運動機構を構成し、水中翼11が所定の仰角を保ったまま垂直方向に揚力中心を変えないで平行移動する。【選択図】図3
