Title
(EN) A HYDROFOIL VESSEL
(FR) NAVIRE HYDROPTÈRE
Abstract
(EN) The invention involves a hydrofoil vessel (1) comprising a hydrofoil assembly (4), and a hull assembly (2) presenting, when the vessel is floating at rest, a vertical symmetry plane (SP), wherein the hydrofoil assembly (4) comprises two struts (401) extending from the hull assembly (2) on opposite transverse sides of the symmetry plane (SP), mainly downwards when the vessel is floating at rest, or mainly partly away from the symmetry plane and partly downwards when the vessel is floating at rest, wherein the hydrofoil assembly (4) comprises two main foil portions (411) each extending from a respective one of the struts (401), at least partly towards the symmetry plane (SP), wherein each strut (401) comprises a strut foil (402) with a non-symmetrical cross-section, and with a pressure side (402P) facing at least partly towards the symmetry plane, and a suction side (402S) facing at least partly away from the symmetry plane (SP).
(FR) La présente invention concerne un navire hydroptère (1) comprenant un ensemble hydroptère (4), et un ensemble coque (2) présentant, lorsque le navire flotte au repos, un plan de symétrie vertical (SP), l'ensemble hydroptère (4) comprenant deux entretoises (401) s'étendant à partir de l'ensemble coque (2) sur des côtés transversaux opposés du plan de symétrie (SP), principalement vers le bas lorsque le navire flotte au repos, ou principalement partiellement à distance du plan de symétrie et partiellement vers le bas lorsque le navire flotte au repos, l'ensemble hydroptère (4) comprenant deux parties de feuille principale (411) s'étendant chacune à partir d'une entretoise respective parmi les entretoises (401), au moins en partie vers le plan de symétrie (SP), chaque entretoise (401) comprenant une feuille d'entretoise (402) avec une section transversale non symétrique, et avec un côté pression (402P) faisant face au moins partiellement vers le plan de symétrie, et un côté aspiration (402S) orienté au moins partiellement à distance du plan de symétrie (SP).
