Title
(EN) VESSEL PROVIDED WITH A FOIL BELOW THE WATERLINE
(FR) NAVIRE DOTÉ D'UNE AILE PORTANTE SITUÉE SOUS LA LIGNE DE FLOTTAISON
Abstract
(EN)
Vessel (11) having a non-planing hull (12) provided with an attached foil (17) which is below the surface (8) of the water and spaced from the hull. The foil is attached in 5 proximity to the aft end of the vessel, and is oriented with a downward tilt of between greater than zero degrees and less than or equal to about 22-relative to the horizontal, to provide a lifting force with a force component in the forward direction. The foil can be located entirely behind the vessel, or partly below the aft hull portion of the vessel with no more than about half the foil being forward of the location (21) where the hull leaves the water. In the latter case, the hull is preferably provided with a recess (16).
(FR)
La présente invention concerne un navire équipé d'une coque non planante dotée d'une aile portante fixée qui se trouve sous la surface de l'eau et est espacée de la coque. L'aile portante est fixée à proximité (5) de l'extrémité arrière du navire et est orientée suivant une inclinaison descendante supérieure à zéro degré et inférieure ou égale à environ 22 ° par rapport à l'horizontale, afin de fournir une force de levage comprenant une composante de force dans la direction avant. L'aile portante peut se trouver entièrement sous le navire ou partiellement sous la coque du navire avec la moitié à peine de l'aile située devant (10) l'emplacement où la coque sort de l'eau. Dans le dernier cas de figure, la coque est pourvue idéalement d'un évidement.
