Deformations of the shape are possible without necessarily causing a break in curve other than that created by the open air passages, the external surface of the element retaining, depending on the setting, continuous curved lines favoring the flow of the air.
- the positioning means act by positioning, in an adjustable manner, between themselves and / or between themselves and the machine, certain points and areas of connection between the aerodynamically shaped element and the positioning means.
- These means can be chosen, for example, from the following elements, fixed or movable with respect to one another, the geometry of which can be variable: beam, torque, truss beam, mast, pivoting wing mast, bipod mast, tripod mast or shaped mast of L, arch, pylon, wishbone, boom, boom boom, articulated arm, outrigger, balestron, spacer, batten, rail, carriage, hoist, jack, and all the hardware, rigging part and mechanical, pneumatic control means, electro-mechanical and hydraulic known in the fields considered.

- the two faces of the aerodynamically shaped element belong to separate envelope parts which determine between them a hollow aerodynamic volume;
- the opening and the means for guiding the air passage are created by a pair of hatches formed respectively in one and the other faces and which are subjected to control means, acting on their closing / opening, on their orientation and their geometry, the opening of the hatch on the upper side being done by displacement of the free upstream edge of the hatch towards the inside of the cavity of the aerodynamic volume, so that the face of the envelope on the upper side retains its aerodynamic profile , despite the opening of the hatch.
- the hatch can be opened both by moving the free downstream edge of the hatch towards the inside of the aerodynamic volume cavity and by moving the free upstream edge of the hatch towards the outside of said cavity. volume.
- the face of the casing on the lower surface provides an aerodynamic profile for the passage of air through the opening, and for its flow over the lower surface.

- the wings V1 and V2 have the same ones C1, C2 and the same rope CP1, CP2.
- the wings V2 and V3 have a different cord CP2, CP3, and a hollow C2, different C3.
- the wings V1 and V4 have the same hollow C1, C4 and a different cord CP1, CP4. It follows that the wings V1, V2, V3 and V4 all have a camber of different shape.
- FIG. 1 we see a monohull boat 1 provided with a mast 2 which supports a thin airfoil designated as a whole by 3, in a single part, and which is divided into three parts 3a, 3b, 3c having between them overlap zones 4ab, 4bc. These overlap zones determine between them slots 68 (FIG. 4) with adjustable geometry and which can be more or less open, or else closed.
- the wing parts have pulling points, in particular, 5-10 ⁇ on their lower edge by means of which the various adjustments and maneuvers of the wing parts are made.
- the frame 34 fitted with pulleys through which ends come from the pulling points 8 and 9, extends far beyond the boom 36.
- the terminal 40 On the carriage 35 is articulated the terminal 40 which can be flexible.
- Bomes 36.40 form a bome with variable geometry. Booms 12, 36, 40 are positioned relative to deck 33 by hoist, carriage, rail assemblies: 50-52, 47-49, 44-46. The concavity of the rail 52 is turned towards the mast 2.
- a pull point 30 ⁇ 1 to which are fixed two ends 30 ⁇ 2, 302 'connected to the craft.
- wing parts 3a, 3b, 3c can be controlled individually, in particular as regards their camber, their twisting, their reduction in surface area or their sprawl.
- the airfoil P passes through the mast which is integrated into the airfoil part 3b. This situation is shown schematically in Figure 2c.
- the mast 2 ′ could pass alongside the sail plane P.
- one of the wing parts could be replaced by the mast as seen in Figure 2b.

- spacers 63 are visible in FIGS. 3 and 4, where a flexible wing according to the invention is shown, having only two parts 3d, 3e having an overlap area 4d, e. To allow individual control of these wing parts, the spacers are fixed to only one of them. As can be seen in FIG. 4, the spacers 63 consist of a part 64 mounted at right angles to a flexible support 65, fixed to the wing part 3c, the part 64 or the junction with the support 65 being articulated.

- Torque 124 is fixed a halyard to hoist or lower the wing 103. In all cases, the pair or pairs are locked against any rotation around the guide support 102.
- the section in FIG. 7 shows how a torque can be produced, that is to say using several plates 129 to 132 arranged end to end and hinged together. More precisely, one end of the plate 129 forms the leading edge of the structure and its opposite end is articulated at 133 on the plate 130 ⁇ which has an opening 134 for the passage of the mast 10 ⁇ 2. Opposite the plate 129, the plate 130 artic is articulated at 135 on an intermediate plate 131, itself articulated at 136 on a plate 132. Opposite the articulation 136, the plate 132 forms the trailing edge of the structure.
- the envelope absorbs differences in length due to the reversibility of the concavity, cambering and twisting. To do this, and / or serve as a reminder, the envelope advantageously has extensible and / or overlapping parts subjected to tensioning means such as 141.
- each side of the assembly constituted by the plates 129 to 132 are arranged two flexible slats of conformation 137 which are connected to the plates by means of lugs 138 fixed to said plates and sliding in grooves provided in said slats.

In fact, at this level, the envelope is in two parts, one, formed by the walls 10 ⁇ 7 and 10 ⁇ 8, the other, by a wall straddling the trailing edge, the ends of one covering the end of the other.
- Cables 139 returned to the foot of the mast, control the relative position of the plates 129 to 132 between them so that by acting on these cables, the camber of the torque formed by said plates can be modified.
- the conformation slats 137 being dependent on said plates, they follow their movement and the casing 10 ⁇ 9 follows the shape taken by the slats.
- the overlapping ends of the walls 10 ⁇ 7 and 10 ⁇ 8 of the envelope are subjected to the tension of tensioners 141.
- the geometry of the aerodynamic shape is obtained by acting suitably on the length of each batten and / or on the position of each plate, taken individually or in combination, thus giving the desired shape to the profiles of the airfoil by distribution of the camber. along the skeleton of the blade according to the intensity of the general camber.

- the hatch 112b '' is designed in the same way but we only see its slot 152, aligned with the slot 151, and its lower operating slat 150 ⁇ .
- the maneuvering slats 150 ⁇ serve as an anchoring point, on the one hand, to a cable 153 which connects them together and, on the other hand, to a series of parallel cables 154 perpendicular to the cable 153.
- One end of the cable 153 is secured to a carriage 155 slidably mounted in a slide 156, which carriage 154 is itself maneuvered using a cable 157 parallel to the cables 154. It is understood that a traction exerted according to arrow F4 on cables 154 and 157 opens the hatches 111b '' and 112b '' allowing the passage of air according to arrow F2.

- the slots 251a-c of the hatches 211a-c are aligned and in their alignment is provided a pull point in 20 ⁇ 4.
- the wing 20 ⁇ 3 is equipped with a series of control slats 258, on either side of each of the hatches 211a-c, and which have zones 259 weakened in terms of rigidity, so that these zones 259 create preferential deflection points of the slats 258.
- the thickness of the slats 258 is constant but their height varies.
- one of the slats 258 - referenced 258'- is coextensive with the lower edge of the wing 20 ⁇ 3.
- a batten of constant section 260 ⁇ is provided at the head of the blade.

- the slats 250 ⁇ , 258 and 260 ⁇ are housed in sleeves fitted in the airfoil and participate in the adjustment of the camber and / or the twist.
- a flexible boom 261 is articulated at 262 on the mast 20 ⁇ 2, boom which is connected to the bridge by a sheet hoist 244 and by another hoist 244 'each cooperating with a carriage 271, 272 and rail system, as shown more clearly in Figure 1 (references 44, 45, 46). It is thus possible to orient the boom relative to the hull 20 ⁇ 1 and relative to the wind.
- the boom 261 itself serves as a support for a rail 263 on which slide two carriages 264 and 264 'connected respectively at the pulling point 267 and 20 ⁇ 4, by two sheets 266 and 266 ', so as to adjust the distance between the different pulling points of the edge of the sail relative to the tack point 270 ⁇ , and to participate in the fixing the intensity of the general arching of the blade.
