Cambering device for profiled sail

Cambering device for a profiled sail comprising:

• an elastically deformable semi-rigid structure, including:
• first and second length sections, extending alongside, forming respectively a first length section secured to a first surface of the profiled sail, and a second length section secured to a second surface of the profiled sail,
• a U-shaped connecting section, interconnecting and extending the first length section and the second length section at a leading edge of the profiled sail, the first length section and the second length section terminating at a trailing edge of the profiled sail in two free ends,
• actuation means connecting together firstly the two free ends of the elastically deformable semi-rigid structure, or at least one of the two free ends, and secondly the U-shaped connecting section, configured for cambering the first length section and the second length section of the elastically deformable semi-rigid structure by a tensioning of the free ends with the U-shaped connecting section of the elastically deformable semi-rigid structure, or at least by a tensioning of one of the two free ends with the U-shaped connecting section of the elastically deformable semi-rigid structure, and generating an offset between the two free ends,
• and wherein the actuation means comprise at least one actuator, having two longitudinal ends, said actuator being retractable when activated with bringing together said two longitudinal ends, said at least one actuator extending along one of the first length section and the second length section of the elastically deformable semi-rigid structure, first length section or second length section, said actuator being internal to the elastically deformable semi-rigid structure, contained in a plane of the elastically deformable semi-rigid structure,
• and wherein a first one of said two longitudinal ends of said at least one actuator is connected to one of the two free ends by an interior tendon while a second one of said two longitudinal ends of said at least one actuator is connected either to an anchoring point secured to the U-shaped connecting section, or to the first one of the two free ends via an angular member secured to the U-shaped connecting section by an exterior tendon, a flexible exterior tension passing outside the elastically deformable semi-rigid structure, and to the profiled sail between the angular member and respectively one of the two free ends.
