Abstract
946,465. Hydrofoil vessels. G. PIAZZA. Oct. 26, 1960 [Nov. 16, 1959], No. 36825/60. Heading B7A. An hydrofoil 10 (Fig. 5) is secured to one arm 2 of a lever pivoted at 4 so that the lift acts behind the pivot. The lift is balanced by a spring 7 at the end of the other arm of the lever, with the result that, if the lift increases, the incidence of the hydrofoil is reduced, or, if the lift decreases, the incidence is increased. The hydrofoil may be inclined upwardly, outwardly and forwardly as in Fig. 8, so that as the depth of immersion increases, and the waterline rises from N-N to A-A the centre of lift changes from n to a and the moment arm of the lift is reduced from x to z. Conversely, as the water line falls, the moment arm is increased. Hydrofoil units in the same transverse plane on opposite sides of the craft may be connected together. A water craft may be supported by two or more pairs of hydrfoils (see Figs. 9-12, not shown).
