| 摘要 |
The invention relates to a hydrofoil arrangement for a hydrofoil craft (4) with at least one fully submerged lifting wing (6, 30, 32), the hydrofoil arrangement (2) comprising at least two struts (8, 10) pivotally arranged on the hydrofoil craft (4), each strut (8, 10) being connected to a lifting wing (6, 30, 32), where the struts (8, 10) are arranged with their centres of effort of hydrodynamic forces (12, 14) behind the pivot axes (A, B) of the struts (8, 10) during forward travel (F) of the hydrofoil craft (4), whereby the struts (8, 10) are arranged to pivot relative to the hydrofoil craft (4) when the hydrofoil craft (4) experiences a disturbance in roll-angle (d), this resulting in a transversal movement (T) of the hydrofoil craft (4) relative to the water surface (5) during forward (F) travel, where the struts (8, 10) when pivoting are arranged to actuate through a direct mechanical coupling (8, 10, 16, 38) at least one means (6; 30, 32; 34, 36) for inducing transversal displacement (E) of the resulting lifting wing's centre of effort (28) in the direction of the transversal movement (T) of the hydrofoil craft (4) in order to modify the transversal distribution of pressure (L) on the at least one lifting wing (6, 30, 32), whereby the hydrofoil craft (4) is arranged to roll back to equilibrium, the hydrofoil arrangement also increasing the roll- stability for a hydrofoil craft. |
