Title
(EN) SHIP WITH SAIL PROPULSION
(FR) NAVIRE À PROPULSION À VOILE
Abstract
(EN)
The invention relates to an at least partially wind-propelled ship, comprising a double airfoil mounted on a structure controlled angularly around a generally vertical axis depending on conditions, where the double airfoil comprises a fore flap and an aft flap at least one of which has a fore-to-aft asymmetry and separated by a slit, where each flap comprises a series of shape members distributed in height, wherein said structure comprises a fore mast and an aft mast connected by a boom member and by a gaff member. The shape members of the fore flap are traversed by the fore mast while being able to turn around an axis defined thereby, while the shape members of the aft flap are traversed by the aft mast while being able to turn around an axis defined thereby. In addition, the aft mast is twistable, the shape members of the aft flap are rotationally locked to said aft mast, and the controller is capable of acting on the bottom and the top of the aft mast.

L'invention concerne un navire au moins partiellement propulsé par le vent, comprenant une double voilure aérodynamique montée sur une structure commandée angulairement autour d'un axe généralement vertical en fonction des conditions, la double voilure aérodynamique comprenant un flap avant et un flap arrière dont au moins un présente une asymétrie avant-arrière, et séparés par une fente, chaque flap comprenant une série d'éléments de forme répartis en hauteur, ladite structure comprenant un mât avant et un mât arrière reliés par un élément bôme et par un élément corne. Les éléments de forme du flap avant sont traversés par le mât avant tout en étant aptes à tourner autour d'un axe défini par celui-ci, tandis que les éléments de forme du flap arrière sont traversés par le mât arrière tout en étant aptes à tourner autour d'un axe défini par celui-ci. De plus, le mât arrière peut subir un mouvement de torsion, les éléments de forme du flap arrière sont verrouillés en rotation audit mât arrière, et le dispositif de commande est apte à agir sur le bas et le haut du mât arrière.
