Abstract
A telescopic profiled wing system, for propelling a vehicle by the wind, the profiled wing system including a mast, and a set of telescopic segments, cooperating with one another during guidance. The telescopic segments form a profiled wing at least in a deployed position in which the various telescopic segments extend, with respect to one another, in the direction of the mast by forming the profiled wing, the profiled wing having a first wing surface and a second wing surface distributed on either side of the mast, the system switches from the deployed position to a retracted position in which the various segments are telescoped into one another, the profiled wing then in a position that takes up less space with respect to the deployed position.

A telescopic profiled wing system, for propelling a vehicle by wind, said profiled wing system comprising:
- a mast, and a set of telescopic segments, cooperating with one another during guidance,
- and wherein said telescopic segments are configured to form a profiled wing at least in a deployed position in which the various telescopic segments extend, with respect to one another, in the direction of the mast by forming said profiled wing, said profiled wing having a first wing surface and a second wing surface distributed on either side of the mast, said system being configured to switch from said deployed position to a retracted position in which the various segments are telescoped into one another, said profiled wing then in a position that takes up less space with respect to the deployed position,
- and said telescopic segments each comprising an elastically deformable, semi-rigid structure, extending along a dimension forming the length of the telescopic segment in the direction of the mast, including:
- two length sections, extending in front of one another, respectively forming a first length section forming a first wing surface of the profiled wing and a second length section secured to a second surface of the profiled wing forming the second wing surface of the profiled wing,
- a U-shaped connecting section, interconnecting the first length section and the second length section by extending them at the leading edge of the profiled wing, the two length sections terminating at the trailing edge of the sail by two free ends,
- and wherein said system includes, for all or part of the telescopic segments, actuating means interconnecting, on the one hand, at least one of the two free ends, and, on the other hand, the U-shaped connecting section, configured to camber the first length section and the second length section of the semi-rigid structure by tensioning one of the two free ends with the U-shaped connecting section of the semi-rigid structure and the generation of an offset between the two free ends,
- and wherein the first wing surface and the second wing surface of the profiled wing formed by the extensions of the various telescopic segments are obtained by said semi-rigid extensional structures.
