[0051] The present disclosure relates to a profiled wing system 1, telescopic, for the propulsion of a vehicle by the wind, said profiled wing system comprising a mast M, and a set of telescopic segments SG, cooperating in guiding relative to each other.

[0052] The mast M may be a single-piece element, typically tubular, according to the embodiment illustrated, or even be itself telescopic to deploy and retract, and according to an embodiment not illustrated.

[0053] Said telescopic segments are configured to form a profiled wing AP, at least in a deployed position P1 for which the different telescopic segments extend, relative to each other, in the direction of the mast M, forming said profiled wing. The profiled wing AP has a first wing surface S1 and a second wing surface S2 distributed on either side of the mast M. Such a deployed position P1 of the profiled wing AP is illustrated in FIG. 5.

[0054] The system is configured to move from said deployed position P1 to a retracted position P2 for which the different segments SG are telescoped into each other, said profiled wing AP then in a less bulky position compared to the deployed position P1. Such a retracted position of said profiled wing AP is illustrated in Figures 1 to 4.

[0055] According to the present disclosure, all or part of the telescopic segments comprise (each) a semi-rigid, elastically deformable structure 2, including: -- two length sections, extending one in front of the other, respectively forming a first length section 20 forming the first wing surface S1 of the profiled wing and a second length section 21 forming the second wing surface S2 of the profiled wing, -- a U-shaped connecting section 22, connecting together by extending them the first section of length 20 and the second section of length 21 at the level of the leading edge BA of the profiled wing, the two length sections ending at the level of the trailing edge BF of the sail by two free ends 23, 24.

[0056] The profiled wing system also comprises, for all or part of the telescopic segments SG, actuating means 4 connecting together, on the one hand, at least one of the two free ends 23, 24, and on the other hand, the U-shaped connecting section 22. The actuating means 4 are configured to arch the first length section and the second length section of the semi-rigid structure by tensioning one of the two free ends 23, 24 with the U-shaped connecting section 22 of the semi-rigid structure 2, and generating an offset d between the two free ends 23, 24. Such an offset d is illustrated in FIG. 15.

[0057] The semi-rigid structures 2 may typically be made of composite material, and typically in whole or in part in the form of flat elements (such as panels) shaped to extend continuously along the section of the structure to form respectively the U-shaped connecting section 22, as well as the first length section 20 and the second length section 21. The flat element extends in the direction of the mast M, in height, along a dimension forming the length of the telescopic segment. Alternatively, the flat elements may be obtained by assembling several sections of flats forming in particular respectively the U-shaped connecting section 22, and the two length sections (first and second referenced 21 and 22). Generally, each semi-rigid structure extends along said dimension forming the length of the telescopic segment along the direction of the mast.

[0058] The first and second wing surfaces S1, S2 of the profiled wing formed by the extensions of the different segments are therefore obtained by the semi-rigid structures 2. A robust system is obtained, avoiding risks of tearing, such as those which can be encountered in profiled, flexible sails, according to the state of the art for example disclosed by WO2021148734.

[0059] In other words, the first wing surface S1 and the second wing surface S2, in particular in the deployed position P1, are obtained by the extension of the semi-rigid structures 2 (exclusively), relative to each other, in the direction of the mast, and as illustrated in particular in figures 5 and following. Consequently, the wing surfaces S1 and S2 therefore do not comprise a tensioned fabric (or flexible film) likely to be torn, and in particular unlike the state of the art disclosed in particular by WO2021148734 or EP 3 299 275 whose wind-contacting surfaces are composed of flexible sails, namely a flexible material such as film or canvas.

[0060] The semi-rigid structures 2 forming the different telescopic segments are shaped components, and therefore self-supporting, in particular in the retracted position P2 for which the segments are retracted into each other, and as illustrated in figures 1 to 3 in particular. The telescopic segments retain their hold in the deployed position P1, but also in the retracted position P2 for which the different semi-rigid structures 2 are telescoped into each other.

[0061] The different segments SG may also comprise a spacer system 3, comprising at least one spacer connecting together the first section of length 20 and the second section of length 21, said spacer configured to work in compression and in tension, to maintain a gap between the two sections of length 20, 21. The spacer system 3 may typically comprise a first spacer 30, connecting together the first section of length 20 and the second section of length 21, as well as a second spacer 31, connecting together the first section of length 20 and the second section of length 21, in a manner parallel to said first spacer 30. The spacers are of fixed or possibly telescopic lengths.

[0062] It is noted that the mast M extends between the struts constituted by the first strut 30 and the second strut 31. The struts (first and second) are configured to work in tension and compression. Optionally, a third strut 33 may extend in parallel, connecting the first section of length 20 and the second section of length 21. This third strut 33 is arranged inside the structure 2 arranged between the second strut 32 and the trailing edge BF of the profiled wing AP.

[0063] Each spacer constituted by the first spacer and the second spacer 30, 31, or even the third spacer 33 of the spacer system 3 can be pivotally articulated at its ends, respectively to the first length section 20 along an axis perpendicular to the plane of the semi-rigid structure and to the second length section 21 along an axis perpendicular to the plane of the semi-rigid structure, the or each spacer 30, 31 being configured to pivot relative to the two length sections, first length section 20 and second length section 21 during the bending and offsetting of the free ends 23, 24; under the effect of the actuating means 4.

[0064] For this purpose, articulated connections 32, comprising a first part integral with the first length section 20 or the second length section 21, or even a second part receiving one end of the spacer 30; 31, the second part being articulated to the first part 33 along a pivot axis substantially perpendicular to the plane of the semi-rigid structure 2 to pivot relative to the two length sections during the bending and offsetting of the free ends 23, 24; under the effect of the actuating means.

[0065] Control means are configured to jointly control in the same direction the different actuating means 4 of the telescopic segments SG to camber the first profiled wing surface S1 and the second profiled wing surface S2. For example, the different segments SG can take a (notably first) cambered position for which the first length section 20 takes a concave profile when the second length section takes a convex profile and / or a (notably second) cambered position in which said second length section 21 has a concave profile when said first length section 20 has a convex profile.

[0066] The semi-rigid structure 2 may have a profile having a plane of symmetry, in a rest position Pr of the semi-rigid structure 2 in which the first section of length 20 and the second section of length 21 have a convex profile. The plane of symmetry of the semi-rigid structure 2 in its rest position extends in the direction between the leading edge BA and the trailing edge BF, parallel to the mast M.

[0067] In the rest position Pr of the semi-rigid structure, it is noted that the first spacer 30 and the second spacer 31 extend respectively substantially perpendicular to the plane of symmetry.

[0068] In at least one arched position Pc1 and / or Pc2 of the semi-rigid structure 2 under the action of the actuating means 4, said first length section 20 has a concave profile when said second length section 21 has a convex profile, or said second length section 21 has a concave profile when said first length section 20 has a convex profile.

[0069] According to one embodiment, the actuating means 4 configured to arch the first length section and the second length section of the semi-rigid structure comprise at least one actuator 40, 41, having two longitudinal ends 40a; 41a, 40b; 41b, said activatable actuator 40, 41 being retractable when activated with bringing its two longitudinal ends together, said at least one actuator 40, 41 extending along one of the two length sections of the semi-rigid structure, first length section 20 or second length section 21, said actuator 40, 41 being internal to the semi-rigid structure 2, contained in the semi-rigid structure 2.

[0070] One of the longitudinal ends 40a, 41a of said at least one actuator 40, 41 is connected to one of the two free ends 23, 24 while the other 40b, 41b of the two longitudinal ends of said at least one actuator 40, 41 is connected to at least one anchoring point secured to the U-shaped connecting section 22. In particular, one of the longitudinal ends 40a, 41a is connected to one of the ends by an internal tendon 42 which is guided by a guide 45 secured to the length section carrying the longitudinal end.

[0071] According to one embodiment, said actuator 40, 41 connecting the anchoring point of the U-shaped connecting section 22 to one of the free ends of the first section of length 20 according to the first possibility, or to one of the free ends of the second section of length 21 according to the section possibility, bypasses the mast M by the side opposite the first section of length 20 according to the second possibility, or bypasses the mast M by the side opposite the second section of length 21 according to the second possibility. Such an embodiment is illustrated in figure 4. According to another possibility, however less favorable in terms of cambering performance, the actuator can bypass the mast by the other side.

[0072] According to one embodiment, the actuation means 4 are configured to bend the semi-rigid structure selectively: - in a first arched position Pc1 in which said first section of length 20 has a concave profile when said second section of length 21 has a convex profile, - in a second arched position Pc2 in which said second section of length 21 has a concave profile when said first section of length 20 has a convex profile.

[0073] The camber position can be adjusted during maneuvers, for example by switching from the first camber position Pc1 to the second camber position Pc2 of the camber devices (with reverse concavity) during tack change maneuvers, whether tacking maneuvers or gybing maneuvers.

[0074] The actuators used for the actuator means can be progressive (and not all or nothing) and take several positions allowing the first and second sail surfaces to be cambered more or less strongly, in one direction or the other. It is possible to adjust the concavity of the sail surface in contact with the wind in order to maximize the effort required to move the vehicle forward depending on the wind conditions.

[0075] According to one embodiment, said at least one actuator of the actuation means may comprise: - a first actuator 40 configured to arch the semi-rigid structure in said first arched position Pc1, one of the longitudinal ends 40a of which is connected to the anchoring point of the U-shaped section while the other longitudinal end 40b is connected to the free end 24 of the second length section 21, said first actuator 40 being configured, in an active state, to retract and pull on the free end 24 connected by the first actuator 40, on the one hand, and on said at least one anchoring point on the other hand, until the creation of the offset d, the connected free end 24 advancing towards the leading edge BA relative to the other free end 23 causing the arching of the semi-rigid structure, the first length section 20 taking a concave profile, the second length section 21 taking a convex profile in said first arched position Pc1, - a second actuator 41 configured to arch the semi-rigid structure into said second arched position Pc2, one of the free ends 41a of which is connected to the anchoring point of the U-shaped section while the other longitudinal end 41b is connected to the free end 23 of the first section of length 20, said second actuator 41 being configured, in an active state, to retract and pull on the free end 23 connected by the second actuator 41, on the one hand, and on said at least one anchoring point on the other hand, until the creation of the offset, the connected free end 23 advancing towards the leading edge BA relative to the other free end 24 causing the semi-rigid structure to curve, the second section of length 21 taking a concave profile, the first section of length 20 taking a convex profile in said second curved position Pc2.

[0076] According to one embodiment, the profiled wing system may comprise a piloting means configured to selectively: - activate the first actuator 40 while keeping the second actuator 41 non-activated to cause said first arched position Pc1, - activate the second actuator 41 while keeping the first actuator 40 non-activated to cause said second arched position Pc2.

[0077] According to one embodiment, all or part of the telescopic segments SG have a securing system 7, which can be activated / deactivated, configured to ensure the securing of the profiled wing to the mast.

[0078] In its activated state, the securing system 7 is advantageously configured to keep the mast away from the semi-rigid structure of the system while ensuring the return of the lateral support due to the pressure of the wind on the profiled wing on the mast. The securing system 7 positions said profiled wing while avoiding impacts between the mast M and the damaging parts of the profiled wing system, and in particular impacts with the spacers 30, 31.

[0079] As can be seen for information purposes in the figures, the fastening system 7 includes: - a first flexible strand 71 linked to the first section of length 21 by two longitudinal ends of the first strand 71, the first strand going around the mast M from the first section of length 20, - a second flexible strand 72 linked to the second section of length 20 by two longitudinal ends of the second strand, the second strand going around the mast M from the second section of length 21.

[0080] The mast thus extends between the first strand 71 and the second strand 72.

[0081] The securing system also comprises an actuator system, activatable, internal to the semi-rigid structure 2, configured to pass the first strand and the second strand into a retracted state configured to tighten the cambering device on the mast M, sandwiched between the first strand 71 and the second strand 72, inside the semi-rigid structure, and as illustrated in the detail view of figure 17.

[0082] The mast thus clamped by the first strand 71 and the second strand 72 is advantageously kept at a distance from the two sections of length 20, 21 by the first strand 71 and the second strand 72 in tension, as well as kept at a distance from the spacers, first spacer 31 and second spacer 32 when present. The wind force on the profiled wing is returned to the mast by the first strand 72 and second strand 72 in tension.

[0083] On the contrary, and when the actuator system is deactivated, the latter is configured to cause a deployed state of the first strand and second strand configured to release the mast; and to allow easy movement of the telescopic segments, along the mast from the first deployed position P1 to the retracted position P2, or vice versa.

[0084] The semi-rigid structures of the different telescopic segments SG may comprise, in whole or in part, the system of spacers 3 comprising the first spacer 30, connecting together the first section of length 20 and the second section of length 21, as well as a second spacer 31, connecting together the first section of length 20 and the second section of length 21, in a manner parallel to said first spacer 30.

[0085] Advantageously, the longitudinal ends of the first strand 71 are secured at two attachment points on the first length section 20 respectively at the junction zones between the first and second spacers 30, 31 and the first length section 20, the longitudinal ends of the second strand 72 being secured at two attachment points on the second length section 21 respectively at the junction zones between the first and second spacers 30, 31.

[0086] The mast M then extends between the spacers constituted by the first spacer 30 and the second spacer 31, the first strand 71 and the second strand 72 clamped on the mast ensuring that the mast with the first spacer 30, on the one hand, and the mast with the second spacer 31, on the other hand, are kept at a distance.

[0087] Regarding the first and second spacers 30, 31, it will be noted that such spacers 30, 31 promote the reliable and firm tightening of the mast by the first strand 71 and the second strand 72, by the compression work of the spacers which opposes the retraction of the first and second strands 71, 72.

[0088] In order to optimize the synergy between the spacers 30, 31 and the strands 71, 72: - the longitudinal ends of the first strand 71 can be secured at two attachment points on the first section of length 20 respectively at the junction zones between the first and second spacers 30, 31 on the one hand, and the first section of length 20, on the other hand, - the longitudinal ends of the second strand 72 can be secured at two attachment points on the second length section 21 respectively at the junction zones between the first and second spacers 30, 31 on the one hand, and the second length section 21, on the other hand.

[0089] Each spacer consisting of the first spacer and the second spacer 30, 31 of the spacer system 3 can be pivotally articulated at its ends, respectively to the first section of length 20 along an axis perpendicular to the plane of the semi-rigid structure and to the second section of length 21 along an axis perpendicular to the plane of the semi-rigid structure, the or each spacer 30, 31 being configured to pivot relative to the two sections of length, first section of length 20 and second section of length 21 during the bending and offsetting of the free ends 23, 24; under the effect of the actuating means 4.

[0090] For this purpose, the telescopic segment SG may comprise articulated connections 32, comprising a first part secured to the first length section 20 or to the second length section 21, or even a second part receiving one end of the spacer 30; 31, the second part being articulated to the first part along a pivot axis substantially perpendicular to the plane of the semi-rigid structure 2 to pivot relative to the two length sections during the bending and offsetting of the free ends 23, 24; under the effect of the actuating means.

[0091] Also, the longitudinal ends of the first strand 71 can advantageously be attached to the first parts of the connectors 32 integral with the first section of length 20 and the longitudinal ends of the second strand 72 are attached to the first parts of the connectors 32 integral with the second section of length 21.

[0092] According to one embodiment, the actuator system of the securing system 7 comprises at least one actuating member on the belt m having two longitudinal ends e1, e2, said actuating member, activatable, being retractable when activated with bringing together of its two longitudinal ends e1, e2.

[0093] Said belt actuating member may be an artificial muscle, in particular a pneumatic muscle. Such an actuator has a casing internally receiving a balloon supplied or discharged with fluid. The flexible casing retracts in length when its section increases under the increase of the supplied balloon or fluid (contraction of the muscle), and deploys in length when its section decreases when the balloon is discharged with fluid (decrease in the fluid pressure). The retraction of the actuator may be progressive by controlling the quantity of fluid supplied into the balloon.

[0094] Such pneumatic actuation systems are commonly called "artificial muscles" consisting of inflatable tubes inserted into protective braids forming an envelope, such that the artificial muscle contracts or expands depending on whether its internal fluid pressure increases or decreases. Such artificial muscles are, for example, described by B. Tondu and P. Lopez in "Compte Rendu de l'Académie des Sciences", t. 320, PP 105-114, 1995.

[0095] Such an artificial muscle is schematically illustrated in its deployed position in Figure 19 and in its retracted position in Figure 20, as well as in a sectional view in Figure 21.

[0096] When the balloon B is supplied with pressurized fluid (for example air) the section of the balloon increases which causes an increase in the section of the envelope Ev in the form of a braid in figure 11.

[0097] Under the effect of the increase in the section of the envelope, the braiding of the envelope generates a force ensuring the retraction of the artificial muscle, by bringing together the longitudinal ends e1 or e2.

[0098] Such an actuator has the following advantages: - not to require the electrification of said profiled wing, - to be a flexible component; unlikely to be aggressive, or even likely to come into direct contact to grip the mast without risk of altering the surface of the mast M.

[0099] According to a first embodiment, the first strand 71 may comprise a first actuating member on the belt m1, in particular a first artificial muscle, and the second strand 72 may comprise a second actuating member on the belt m2, in particular a second artificial muscle.

[0100] Such an embodiment is illustrated for information purposes in Figure 17 when the first belt actuator member m1 and the second belt actuator member m2 are artificial muscles. The longitudinal ends e1 and e2 of the first belt actuator member m1 are integral in two attachment positions on the first parts of the connectors 32 linked to the first length section 20, respectively at the junction zone with the first spacer 30 and the second spacer 31. Similarly, the longitudinal ends e1 and e2 of the second belt actuator member m2 are integral in two attachment positions on the first parts of the connectors 32 linked to the second length section 21 respectively at the junction zone with the first spacer 30 and the second spacer 31.

[0101] Said at least one actuator ensuring the bending of the structure, where appropriate first actuator 40 and second actuator 41 may be an actuator which retracts when supplied with fluid such as an artificial muscle, in particular a pneumatic muscle. Such an actuator, previously described, and is not redeveloped. It has an envelope internally receiving a balloon supplied or discharged with fluid. The flexible envelope retracts in length when its section increases under the increase of the balloon supplied or fluid (contraction of the muscle), and deploys in length when its section decreases when the balloon is discharged with fluid (decrease in the pressure of the fluid). The retraction of the actuator may be progressive by controlling the quantity of fluid supplied into the balloon. The actuator (in particular first or second) may also be a pneumatic cylinder.

[0102] According to one embodiment, the artificial muscles of the actuators 40, 41 and / or of the actuator members m of the plurality of segments are supplied with fluid by one or more flexible elastic pipes AL1, AL2, AL3, shaped in the form of a serpentine (not illustrated), extending in the direction of the height of the mast M. The flexible elastic pipe(s) are configured to deploy by spreading the turns of the serpentine in the deployed position of said telescopic wing and to retract by bringing the turns of the serpentine closer together under the elasticity of the serpentine, in the retracted position P2 of the profiled wing AP.

[0103] According to one embodiment, the different telescopic segments SG, and in particular the different associated semi-rigid structures, are of decreasing dimensions (in particular in directions perpendicular to the mast), depending on the height of the mast M, in said deployed position P1, so that a telescopic segment, higher in the deployed position is, relative to a consecutive, lower telescopic segment, caused to be inserted into the lower telescopic segment, in said retracted position P2 for which the different telescopic segments are telescoped into each other.

[0104] Generally, said at least one actuator 40, 41 and / or the first belt actuating member m1 and the second belt actuating member m2 are positioned, in the semi-rigid structure, preferably at the lower end of the telescopic segment SG. SG. Such positioning makes it possible, in the retracted position P2, to telescope the different segments SG into each other, maximizing the interlocking between the segments, as well as the vertical compactness of the profiled wing in the retracted position P2, and without said at least one actuator and / or the first belt actuating member m1 and the second belt actuating member m2 constituting an obstacle substantially limiting the retraction of the segments.

[0105] Generally, the profiled wing system may comprise guide means between the consecutive telescopic segments, comprising at least a first guide element GD1, extending along the height of a lower telescopic segment SG, preferably internal to the semi-rigid structure 2 of the telescopic segment, and cooperating in guiding with at least a second guide element GD2, preferably external, in the lower part of an upper telescopic segment.

[0106] The second guide element GD2 cooperates in guiding with the first guide element GD1 according to a limited stroke to ensure sliding between the two consecutive telescopic segments between the retracted position P2 and said deployed position P1 of the profiled wing AP. The profiled wing system AP may preferably comprise several pairs of first guide element GD1 / second guide element GD1, which are distributed over the first sections of length 20 of the two consecutive segments and which are distributed over the second sections of length 21 of the two consecutive segments. The first guide element GD1 may be a flexible, elongate element and the second guide element GD2, a sliding loop on the flexible, elongate element.

[0107] Generally speaking, the various telescopic segments SG comprise a head telescopic segment SGT which constitutes the uppermost telescopic segment in said deployed position P1 of said profiled wing AP, and a foot telescopic segment SGP which is integral in the lower part of the mast and which constitutes the lowermost telescopic segment in said deployed position P1.

[0108] The telescopic head segment SGT is connected to a hoisting halyard DR resting on a POT jib at the top of the mast M. The halyard is configured to ensure the deployment of the different telescopic segments from the retracted position P2 to the deployed position P1 of said profiled wing AP.

[0109] The telescopic foot segment SGP is connected to the mast, preferably via an adjustment device configured to ensure an orientation of the profiled wing AP around the mast M. Such an adjustment device comprises a mechanism 5 for adjusting the orientation of the telescopic foot segment SGP around the mast M.

[0110] The mechanism 5 for adjusting the orientation of the telescopic segment of the SGP foot around the mast M may comprise: - a first part 51 linked in rotation to the mast, without possibility of rotation between the first part 51 and the mast M, - a second part 52 secured to the semi-rigid structure of the telescopic foot segment, via a spacer system 3 of the telescopic foot segment, the spacers connecting the first section of length 20 and the second section of length 21 to each other, in an articulated manner, - a mechanical transmission 6, preferably motorized, ensuring adjustment of the rotational position of the second part 52 around the first part 51.

[0111] The spacer system may comprise the first spacer 30, the second spacer 31 and a third spacer 33. It is noted that the first spacer 30 and the second spacer 31 are articulated in their middle portion on the second part 52, typically via axis pivots substantially parallel to the mast. The third spacer 33 is articulated to the second part 52, for example via a ball joint.

[0112] Generally, the mechanical transmission 6 can include: - a toothed crown 60 integral in rotation with the first part, - a motorized pinion 61 embedded in the second part, - a toothed belt 62 connecting the toothed crown 60 to the motorized pinion 61.

[0113] The mechanical transmission 6 is thus configured so that a rotation of the motorized pinion causes the rotation of the second part 52 relative to the first part 51 by changing the orientation of the telescopic foot segment SGP around the mast M.

[0114] The first part 51 linked in rotation to the mast can possibly slide relative to the mast according to a stroke limited to the descent, and in order to store the profiled wing in its retracted position in a formwork preferably arranged under the upper deck PTA or on the contrary to the ascent, in order to remove the retracted wing from the formwork and position it above the upper deck PT of the ship.

[0115] The present disclosure further relates to a vehicle such as a ship having wind propulsion comprising at least one telescopic, profiled wing system according to the present disclosure.

[0116] The vehicle may be a vessel, for example monohull or multihull, comprising an upper deck above which extends the mast M, at least in part and said profiled wing in said deployed P1, from the lower telescopic segment, from the foot SGP, to the upper telescopic segment from the head SGT.

[0117] According to one embodiment, said mast extends below the upper deck PT, through a formwork, the mast anchored to a structure of the ship below the level of the formwork. Said formwork is arranged below the level of the upper deck. In such a case, said telescopic wing then in said retracted position is configured to be lowered through an opening of the upper deck below the upper deck PT and stored in said formwork.

[0118] A CV cover system may be configured to close the upper opening in said retracted position P1 and stowed position of said telescopic wing AP in the formwork. The CV cover system may also be configured to close the opening in the upper deck PT in the deployed position P1 of said telescopic wing, said profiled wing then outside the formwork. In this latter closed position, the cover system may come to bear on the mast, at a distance and above its anchoring to the ship made under the formwork. Such support of the cover system on the mast reinforces the maintenance of the mast and its resistance to bending under the force of the profiled wing. List of reference signs
