Abstract: A process for deployment of a tethered-wing traction system, including a step of flight of a traction wing (5) relative to a stowing mast (4), and including, before the flight step, a step of windsock folding of the traction wing (5), wherein: the median area (15) of the leading edge (16) is retained relative to the stowing mast (4) at a first height on the stowing mast (4); the lateral portions (19) of the leading edge (16) are retained relative to the stowing mast (4) at a second height at least on the stowing mast (4), which is lower than the first height, the leading edge (16) forming a windsock air inlet with a circular opening; the leading edge (16) forming a windsock air inlet with a circular opening; the trailing edge (17) is reclosed by bringing the lateral portions (19) of the trailing edge (17) towards one another.

Abstract: Tethered-wing traction system including: a traction wing; a base platform; a mooring mast; a plurality of folding lines; a folding carriage adapted to slide along the mooring mast; an input device (22) which is attached to the leading edge of the traction wing and which has a hooking arm (25) provided with a hooking stem (27A, 27B, 27C), one of the folding lines projecting into the extension of the hooking stem (27A, 27B, 27C); the folding carriage having a gripping hook which is movable between a retracted position and a gripping position in which the gripping hook surrounds the hooking stem (27A, 27B, 27C).

Abstract: Captive wing traction system (1) including: a trajectory control flying device (7) attached to a traction wing (5) by fixed suspension lines (6) and mobile suspension lines (6), the trajectory control flying device (7) being adapted to control the mobile suspension lines (6); a traction line (8) connecting the trajectory control flying device (7) to the base platform (3); a guide line (9) that connects the leading edge (16) of the traction wing (5) to the trajectory control flying device (7); a stowage line (10) one end of which is connected to the base platform (3) and the other end of which is slidably connected to the guide line (9); a deflector element (13) attached to the stowage mast (4).

Abstract: Tethered-wing traction system including: a traction wing (5), a base platform (3), a mooring mast (4), a plurality of folding lines (10A,10B,10C), a furling line (13), a mooring carriage (12B), a folding carriage (12C, 12D, 12E), a furling carriage (12A), and a control module (64) having at least the following two operating modes: a folding mode in which the mooring carriage (12B) and the folding carriage (12C, 12D, 12E) are spaced apart from each other; and a furling mode in which the furling carriage (12A) and the mooring carriage (12B) are spaced apart from each other.

Abstract: A traction system, notably for a ship, includes a fixed station, at least one first sail and one second sail, the first sail comprising a wing and being connected to a winch of the fixed station by a first hauling cable, the second sail includes a second wing and being connected to a winch of the fixed station by a second hauling cable. The fixed station includes a mast which is equipped with a first conveyor dedicated to mooring the first wing to this mast and with a second conveyor dedicated to mooring the second wing to this mast.

Abstract: A traction system for a watercraft, including a sail and a fixed station that includes a mast and a winch which is connected to the sail by a traction cable, the system further including a bottom part that is supported by the traction cable, and fold lines, each of which has an end that is attached to a leading edge of the sail, and another end that is supported by the bottom part. The fixed station includes a base that accommodates the bottom element when the sail is retracted by the winch; and structure for grasping each fold line and pulling same towards the mast so as to retract the leading edge against the mast and fold the sail once the winch has retracted same close to the station.
