Description

Ensemble portant asservi à aile profilée pour bateau semi rigide.  Slave wing slave support assembly for semi rigid boat.
La présente invention concerne un ensemble portant à aile profilée (une telle aile profilée étant couramment dénommée « foil » dans la terminologie anglo-saxonne répandue, ou encore aile), pour des bateaux non propulsés par des voiles. Il peut s'agir par exemple de bateaux propulsés par moteur thermique, par énergie électrique, hydraulique, solaire, par hydrogène, par hydrojet, etc. The present invention relates to a set bearing profiled wing (such profiled wing being commonly referred to as "foil" in the common English terminology, or wing), for boats not propelled by sails. It may be for example boats powered by heat engine, electric power, hydraulic, solar, hydrogen, hydrojet, etc.
En particulier, l'invention s'applique aux bateaux semi rigides motorisés. Le « moteur » de ces bateaux peut être un moteur thermique, électrique, hydraulique, ou d'une autre nature. L'organe de propulsion de ce moteur peut être par exemple une hélice ou une turbine. Dans l'exemple qui sera détaillé dans cette demande il s'agit d'un moteur à hélice.  In particular, the invention applies to motorized semi-rigid boats. The "engine" of these boats can be a thermal engine, electric, hydraulic, or of another nature. The propulsion member of this engine may be for example a propeller or a turbine. In the example which will be detailed in this application it is a propeller motor.
Le concept de foil a été développé depuis des années pour des bateaux de types divers, et notamment pour des bateaux à voile.  The concept of foil has been developed for years for boats of various types, and especially for sailing boats.
Dans ces développements, le bateau équipé d'un ou plusieurs foils immergés dans l'eau est destiné à flotter sur l'eau à l'arrêt ou à vitesse réduite (régime archimédien), comme un bateau sans foils.  In these developments, the boat equipped with one or more foils immersed in water is intended to float on the water at a stop or at a reduced speed (Archimedean regime), like a boat without foils.
Lorsque le bateau avance sur l'eau (propulsé par des voiles, ou un autre type de propulsion) la partie du ou des foil(s) qui est immergée est orientée de manière à générer une portance dans l'eau. Cette portance se répercute sur le bateau qui est solidaire du ou des foil(s). Selon le point d'application de cette portance sur le foil, selon la position du foil par rapport au bateau et selon l'orientation de cette portance, cette portance peut être utilisée pour générer divers effets (par exemple : tendre à soulever le bateau au-dessus de l'eau, ou exercer sur le bateau un moment de redressement).  When the boat is advancing on water (propelled by sails, or some other type of propulsion) the part of the foil (s) that is immersed is oriented so as to generate lift in the water. This lift is reflected on the boat that is attached to the foil (s). Depending on the point of application of this lift on the foil, depending on the position of the foil with respect to the boat and depending on the orientation of this lift, this lift can be used to generate various effects (for example: tending to lift the boat at above the water, or exercise on the boat a moment of recovery).
Dans le cas des bateaux à voile, les foils sont typiquement utilisés pour contrer la gite du bateau sous voile, et tendre ainsi à le redresser. De manière plus marginale, les foils sur bateaux à voile peuvent être utilisés pour tendre dans une certaine mesure à soulever le bateau, de manière à diminuer sa surface mouillée (c'est à dire sa surface de coque qui est immergée). In the case of sailing boats, the foils are typically used to counter the cottage of the boat under sail, and thus tend to straighten it. In a more marginal way, the foils on sailing boats can be used to stretch to some extent to lift the boat, so as to reduce its wet surface (ie its hull surface which is submerged).
Dans tous les cas, les foils de bateaux à voile, lorsqu'ils sont disposés par paires (généralement une seule paire) de part et d'autre de l'axe longitudinal du bateau, ne sont utilisés que partiellement : seul le foil situé sous le vent du bateau gité « travaille » réellement, l'autre foil n'étant pas utile, voire ayant des effets nuisibles à la bonne marche du bateau car se trouvant immergé avec une orientation non désirée mais résultant de l'implantation du foil sur le bateau.  In all cases, the foils of sailing boats, when arranged in pairs (usually only one pair) on either side of the longitudinal axis of the boat, are used only partially: only the foil located under the wind of the boat gite "works" really, the other foil not being useful, even having effects detrimental to the good running of the boat because being immersed with an unwanted orientation but resulting from the implantation of the foil on the boat.
Pour éviter de tels effets nuisibles on a imaginé des foils escamotables au travers de la coque du bateau. On connaît ainsi depuis peu des bateaux à voile dont les foils situés respectivement à bâbord et tribord du bateau, sont escamotables à volonté et indépendamment l'un de l'autre. De la sorte, quand le bateau est gité (ce qui est le cas lorsque le bateau avance, et qu'on cherche à utiliser ses foils) on déploie le foil sous le vent hors de la coque du bateau (ainsi ce foil sous le vent est pleinement immergé, et actif hydrodynamiquement en générant de la portance), tandis qu'on escamote au travers de la coque du bateau le foil situé de l'autre côté du bateau, au vent du bateau (de la sorte ce foil au vent n'est pas ou que très peu immergé, et ses éventuels effets hydrodynamiques indésirables sont évités).  In order to avoid such harmful effects, retractable foils have been devised through the hull of the boat. Thus recently known sailing boats whose foils respectively port and starboard of the boat, are retractable at will and independently of one another. In this way, when the boat is lying (which is the case when the boat is moving forward, and we try to use its foils) we deploy the leeward foil out of the hull of the boat (so this foil under the wind is fully immersed, and active hydrodynamically by generating lift), while the foil on the other side of the boat is sailed through the hull of the boat, to the wind of the boat (so that foil in the wind) is not or only very immersed, and its possible undesirable hydrodynamic effects are avoided).
Ces bateaux à voile connaissent actuellement un développement important. Avec ces bateaux les foils sont donc utilisés en alternance (de manière à ce que seul le foil sous le vent travaille), et de récents développements ont donné accès à des foils escamotables pour cette utilisation en alternance.  These sailing boats are currently undergoing significant development. With these boats the foils are used alternately (so that only the foil under the wind works), and recent developments have given access to foils retractable for this use alternately.
Dans le cas des bateaux à moteurs, l'utilisation des foils est sensiblement différente, puisque ces bateaux ne sont pas conçus pour naviguer en position gitée. Au contraire, ces bateaux à moteur doivent naviguer « à plat » sur l'eau, sans giter.  In the case of motor boats, the use of the foils is significantly different, since these boats are not designed to navigate in a gite position. On the contrary, these motor boats must navigate "flat" on the water, without citation.
L'invention dont il est question ici concerne les bateaux à moteur, et plus particulièrement les bateaux de type semi rigides. Les bateaux semi rigides sont un type de bateau motorisés bien connus qui comprennent une coque rigide et des boudins de protection latéraux gonflables. Ces bateaux ne sont pas aujourd'hui équipés de foils. La raison est que cette intégration de foil sur des bateaux motorisés semi-rigides pose de nombreux problèmes, qui sont liés notamment au dimensionnement et à l'intégration des foils dans le bateau, aux structures de bateau qui doivent supporter des efforts liés aux foils qui sont importants et qui sont répartis différemment de ce qu'on connaît des efforts appliqués à des semi rigides sans foils, et l'encombrement de l'installation qui pourrait empiéter notamment sur le volume intérieur habitable (par ailleurs réduit), dans le respect des conditions de sécurité et des normes du secteur. Le problème est particulièrement vif pour l'adaptation de foils sur un bateau semi rigide qui répond à des contraintes d'utilisation très spécifiques qui sont différentes de celles des bateaux à voile ou des bateaux à moteur. Un autre problème qui se pose avec l'intégration de structures portantes à aile portante sur des bateaux semi rigides motorisés est la nature particulière du bateau semi rigide qui est utilisé dans une application dite de beaching en langage professionnel communément adopté, à savoir d'accostage sur la plage. L'avantage d'un semi rigide étant sa souplesse d'utilisation, sa légèreté, pour aborder des lieux difficiles et des plans d'eau ou la profondeur est faible voire nulle en cas d'accostage. Par ailleurs et de manière fondamentale vis-à-vis des voiliers à foils, les structures portantes doivent être adaptées aux caractéristiques de navigation propres au semi-rigide, qui navigue notamment sans gite, à l'inverse d'un bateau à voile (et notamment des bateaux à voile munis de foils). The invention in question here relates to motor boats, and more particularly to semi-rigid type boats. Semi-rigid boats are a well-known type of motorized boat that includes a rigid hull and inflatable side shields. These boats are not equipped with foils today. The reason is that this integration of foil on semi-rigid motorized boats poses many problems, which are related in particular to the dimensioning and the integration of the foils in the boat, to the structures of boat which must support efforts related to the foils which are important and which are distributed differently from what is known of the forces applied to semi-rigid without foils, and the congestion of the installation which could encroach in particular on the interior habitable volume (otherwise reduced), in the respect of safety conditions and industry standards. The problem is particularly acute for the adaptation of foils on a semi-rigid boat that responds to very specific operating constraints that are different from those of sailing boats or motor boats. Another problem that arises with the integration of load-bearing load-bearing structures on motorized semi-rigid boats is the particular nature of the semi-rigid boat which is used in a so-called beaching application in commonly adopted professional language, namely berthing on the beach. The advantage of a semi-rigid being its flexibility of use, its lightness, to tackle difficult places and water bodies or the depth is low or zero in case of docking. Moreover and fundamentally vis-à-vis the sailboats foils, the load-bearing structures must be adapted to the navigation characteristics of the semi-rigid, which navigates including without gite, unlike a sailing boat (and in particular sail boats with foils).

Dans la présente la demande, on appelle axe longitudinal l'axe de symétrie du bateau semi rigide, plan horizontal un plan contenant l'axe longitudinal et la ligne de flottaison du bateau, et axe vertical un axe perpendiculaire au plan horizontal.  In the present application, the longitudinal axis of symmetry of the semi-rigid boat, horizontal plane is a plane containing the longitudinal axis and the waterline of the boat, and vertical axis is an axis perpendicular to the horizontal plane.
La figure 1 représente une vue en coupe d'un bateau semi rigide traditionnel (1 ), sans foils. Il est précisé que les signes de référence utilisés sur cette figure pourront être repris, pour des éléments identiques ou similaires, à propos de bateaux selon l'invention.  Figure 1 shows a sectional view of a traditional semi rigid boat (1) without foils. It is specified that the reference signs used in this figure may be used, for identical or similar elements, about boats according to the invention.
Le bateau (1 ) de type connu et représenté sur la figure 1 est fabriqué comme suit : une coque (13) rigide de forme générale en V. Un plancher (P) ferme la coque pour servir de plancher et d'appuis aux passagers et aux équipements. Une carlingue (12) à l'intérieur du volume défini par la coque (1 3) et du plancher (P) arrimée à la coque (13) vient consolider la structure de la coque dans le creux formé par la coque (12). La carlingue peut par exemple être des parois internes rigides qui viennent rigidifier la structure et notamment le creux entre le plancher (P) et la coque (13). A noter que la carlingue (12), la coque (13), le plancher (P), le livet (14) sont préférentiellement tous fabriqués à partir du même matériau et peuvent être fabriqués en un nombre très limité voir unique de pièces. L'enjeu étant de donner un compromis de rigidité nécessaire pour absorber les chocs du bateau sur l'eau et les efforts reçus, tout en maintenant une légèreté suffisante. Le pourtour de bord de plancher forme un livet (14). Le livet (14) est rigide et solidarisé à la coque. Il remonte et constitue comme une petite marche sur le pourtour du plancher afin notamment que la pointe des pieds des utilisateurs ou des objets qui traînent sur le plancher ne viennent pas taper contre le boudin creux gonflé (1 1 ) qui borde le flanc latéral bâbord, puis la proue, puis le flanc latéral tribord du bateau. Un emménagement (17), aussi appelé emménagement central, est couramment installé au centre du plancher. En variante, l'emménagement (17) peut être décalé par rapport au centre du plancher vers le côté bâbord ou le côté tribord, ou vers la proue ou la poupe du bateau. Il consiste en un ou plusieurs caissons qui logent et maintiennent la console qui regroupe les organes de commande du bateau, comme les commandes moteur. Ils peuvent également contenir un/des coffres pour le rangement ou tout autre accessoire pour des utilisations spécifiques. The boat (1) of known type and shown in Figure 1 is manufactured as follows: a shell (13) rigid V-shaped general A floor (P) closes the shell to serve as floor and support for passengers and equipment. A cabin (12) inside the volume defined by the hull (1 3) and the floor (P) secured to the hull (13) consolidates the structure of the shell in the hollow formed by the shell (12). The cabin may for example be rigid internal walls that stiffen the structure and in particular the hollow between the floor (P) and the shell (13). Note that the cabin (12), the hull (13), the floor (P), the livet (14) are all preferably made from the same material and can be manufactured in a very limited number or even single pieces. The challenge is to give a compromise of rigidity necessary to absorb the shocks of the boat on the water and the efforts received, while maintaining a sufficient lightness. The edge of the floor edge forms a livet (14). The livet (14) is rigid and secured to the hull. It goes up and is like a small walk around the floor so that the tip of the feet of the users or objects lying on the floor do not knock against the hollow inflated roll (1 1) bordering the port side flank, then the bow, then the starboard side of the boat. A move (17), also called a central move, is commonly installed in the center of the floor. Alternatively, the move (17) may be offset from the center of the floor to the port or starboard side, or to the bow or stern of the boat. It consists of one or more boxes that house and maintain the console that groups together the controls of the boat, such as engine controls. They may also contain storage chests or other accessories for specific uses.
La hauteur de l'emménagement (17) est dimensionnée de manière à permettre au conducteur du bateau de voir la mer devant lui. Cette hauteur est ainsi limitée, sur tous les bateaux semi rigides.  The height of the move (17) is sized to allow the boat driver to see the sea in front of him. This height is thus limited on all semi-rigid boats.
Comme représenté, sur la figure 2, avec une vue de dessus à la poupe bateau du semi rigide est positionné le moteur (20) à hélice.  As shown in FIG. 2, with a top view at the boat stern of the semi-rigid is positioned the propeller motor (20).
Les figures 3a et 3b représentent deux vues en coupe d'un bateau semi rigide selon l'invention qui comprend des ailes 40 dites de portance avant.  Figures 3a and 3b show two sectional views of a semi-rigid boat according to the invention which comprises wings 40 called forward lift.
Sur ces figures le bateau est représenté en position d'accostage, figure 3a, ailes rétractées, et en position de navigation, figure 3b, ailes déployées. L'invention propose une solution astucieuse qui permet en positon d'accostage de ranger les ailes portantes, de telle sorte qu'elles ne gênent ni pour l'accostage, ni pour l'espace habitable sur le bateau. Par contre en position de navigation, les ailes se déploient sous le bateau et permettent ainsi de surélever la coque au-dessus du niveau de l'eau. In these figures the boat is shown in the docking position, Figure 3a, retracted wings, and in the navigation position, Figure 3b, wings extended. The invention proposes a clever solution which allows in docking position to store the load-bearing wings, so that they do not interfere with for docking, nor for the living space on the boat. By cons in sailing position, the wings unfold under the boat and allow to raise the hull above the water level.
Le rangement et le déploiement des ailes (40) peut se faire de manière symétrique et simultanée. Autrement dit, les deux ailes (40) sont déployées et rangées en même temps, et leur position est symétrique par rapport à l'axe longitudinal. En ceci les foils sont utilisés très différemment des foils mis en œuvre sur des voiliers destinés à naviguer gités.  The storage and deployment of the wings (40) can be done symmetrically and simultaneously. In other words, the two wings (40) are deployed and stored at the same time, and their position is symmetrical with respect to the longitudinal axis. In this the foils are used very differently from the foils used on sailing boats designed to navigate gites.
Ainsi, pour un bateau (100) selon l'invention naviguant sans gite, les ailes (40) peuvent être toutes deux déployées simultanément et de manière symétrique, à l'inverse des voiliers qui déploient leurs surfaces portantes de manière non symétrique et non simultanée, en fonction de leur gite. Par ailleurs, la portance évolue de manière symétrique de part et d'autre de l'axe longitudinal du bateau lors du rangement et du déploiement des ailes (40), et le bateau (100) n'est donc pas déstabilisé par l'opération.  Thus, for a boat (100) according to the invention sailing without a cottage, the wings (40) can both be deployed simultaneously and symmetrically, unlike sailboats that deploy their bearing surfaces in a non-symmetrical and non-simultaneous manner , according to their lodging. Furthermore, the lift evolves symmetrically on both sides of the longitudinal axis of the boat during the storage and deployment of the wings (40), and the boat (100) is not destabilized by the operation .
Comme représenté en figure 4, l'aile (40) comporte sensiblement deux parties : une partie dite de portance, aussi appelée horizontale, et une partie qui permet de descendre l'horizontale dans l'eau, qui est un arbre qui peut se nommer vertical.  As shown in FIG. 4, the wing (40) comprises substantially two parts: a so-called lift portion, also called horizontal, and a portion that allows the horizontal to be lowered into the water, which is a tree that can be named vertical.
On précise que ces termes d' « horizontal » et « vertical » employés dans ce texte à propos des deux parties de l'aile (ou du foil, ces deux termes étant ici équivalents) ne déterminent pas l'orientation absolue de ces deux parties, qui ne sont pas nécessairement orientées selon l'horizontale « vraie » et la verticale « vraie ».  It is specified that these terms "horizontal" and "vertical" used in this text about the two parts of the wing (or foil, these two terms being equivalent here) do not determine the absolute orientation of these two parts. , which are not necessarily oriented according to the "true" horizontal and the "true" vertical.
L'horizontale comprend une partie principale d'horizontale (42) qui est la partie qui génère la totalité (ou en variante : une partie substantielle) de la portance de l'aile (40). La partie principale d'horizontale (42) présente une surface suffisamment importante pour générer une portance apte à soulever la coque (13) au moins partiellement hors de l'eau.  The horizontal includes a main horizontal portion (42) which is the portion that generates all (or alternatively: a substantial portion) of the lift of the wing (40). The main horizontal portion (42) has a surface large enough to generate a lift capable of lifting the hull (13) at least partially out of the water.
La longueur (l sur la représentation de la figure 6) de la partie principale d'horizontale (42) est ainsi de préférence comprise entre 80 % du rayon (r dans la représentation de la figure 6) du boudin (1 1 ) et 1 10 % du rayon du boudin (1 1 ), de préférence de l'ordre de 95 % du rayon du boudin (1 1 ). Par exemple, pour un boudin (1 1 ) de 29 cm de rayon r, la longueur l de la partie horizontale est avantageusement comprise entre 22 cm et 31 cm, de préférence de l'ordre de 27 cm. The length (1 in the representation of FIG. 6) of the main horizontal part (42) is thus preferably between 80% of the radius (r in the representation of FIG. 6) of the strand (1 1) and 1 10% of radius of the flange (1 1), preferably of the order of 95% of the radius of the flange (1 1). For example, for a flange (11) 29 cm in radius r, the length l of the horizontal portion is preferably between 22 cm and 31 cm, preferably of the order of 27 cm.
L'horizontale comprend également un bout d'aile à boudin (41 ) dont la forme incurvée épouse la forme du boudin (1 1 ) sur un secteur angulaire de préférence compris entre 10 degrés et 50 degrés, de préférence d'une trentaine de degrés. Grâce à cette correspondance astucieuse des formes du bout d'aile et du boudin, l'aile en position rangée ne dépasse pas sensiblement à l'extérieur du boudin.  The horizontal also comprises a flanged wing tip (41) whose curved shape matches the shape of the flange (1 1) on an angular sector preferably between 10 degrees and 50 degrees, preferably about thirty degrees . Thanks to this clever correspondence of the shapes of the wingtip and the flange, the wing in the stowed position does not exceed substantially outside the flange.
De manière avantageuse et grâce à cette correspondance de formes, en position rangée, le bout d'aile à boudin (41 ) ne s'éloigne ainsi pas du boudin (1 1 ) de plus d'une distance (D sur la représentation de la figure 7) comprise entre 0 et 10 cm, de préférence sensiblement égale à 2 cm.  Advantageously and thanks to this correspondence of shapes, in a stowed position, the flange wingtip (41) thus does not move away from the flange (1 1) by more than a distance (D in the representation of the Figure 7) between 0 and 10 cm, preferably substantially equal to 2 cm.
Ainsi, le gabarit (notamment la largeur) du bateau (100) dont les ailes Thus, the jig (in particular the width) of the boat (100) whose wings
(40) sont en position rangée est sensiblement égal à celui d'un bateau ne présentant pas d'ailes (40). Le transport routier d'un bateau (100) avec ailes (40) n'est donc pas limité. (40) are in the stowed position is substantially equal to that of a boat having no wings (40). The road transport of a boat (100) with wings (40) is therefore not limited.
Par ailleurs, la forme incurvée du bout d'aile à boudin (41 ) sert pour tenir les virages lorsque le bateau (100) gite sur une aile (40) (cette gite étant en tout état de cause plus modérée que les gites observées sur les bateaux à voiles à foils - et cette gite est également très transitoire, étant liée au virage). En effet, quelle que soit la gite temporaire du bateau (100), une portion du bout d'aile à boudin (41 ) sera orientée de façon optimale pour générer de la portance.  Furthermore, the curved shape of the flange wingtip (41) is used to hold the turns when the boat (100) lies on a wing (40) (this cottage being in any case more moderate than the cottages observed on the foil sailboats - and this cottage is also very transient, being related to the turn). Indeed, whatever the temporary cottage of the boat (100), a portion of the flange wingtip (41) will be optimally oriented to generate lift.
Cet aspect de forme incurvée du bout d'aile à boudin peut être combiné avec les autres aspects décrits dans ce texte, ou mis en œuvre séparément voire isolément.  This curved wing tip shape can be combined with the other aspects described in this text, or implemented separately or in isolation.
La verticale comprend une première partie rectiligne de verticale (43 ) puis une seconde partie de verticale (44) qui s'incurve vers le centre du bateau selon un angle d'environ une quinzaine de degrés. Cette forme incurvée vers l'intérieur est conçue pour optimiser le compromis de rangement dans le bateau sur une hauteur acceptable et de descente sous l'eau à une profondeur maximum afin d'élever au maximum le bateau, le tout en se jouant des contraintes d'espace propre à l'exiguïté d'un bateau semi rigide, et plus particulièrement des bateaux des petites tailles de la gamme existantes de bateaux semi- rigides. The vertical comprises a first rectilinear vertical portion (43) and a second vertical portion (44) curving towards the center of the boat at an angle of about fifteen degrees. This curved inward shape is designed to optimize the compromise of storage in the boat on an acceptable height and descent under water to a maximum depth to raise the boat to the maximum, while playing with space constraints peculiar to the exiguity of a semi-rigid boat, and more particularly small boats of the existing range of semi-rigid boats.
La partie rectiligne de verticale (43) peut présenter un angle d'inclinaison (a sur la représentation de la figure 6) par rapport à l'axe vertical (vrai (tel que défini au début de ce texte).  The rectilinear vertical portion (43) may have an angle of inclination (a in the representation of Figure 6) relative to the vertical axis (true (as defined at the beginning of this text).
De manière avantageuse, l'angle d'inclinaison a par rapport à l'axe vertical est compris entre 0 degré et un angle maximal amax de 45 degrés, de préférence entre 30 degrés et 40 degrés, de préférence sensiblement égal à 36 degrés.  Advantageously, the angle of inclination with respect to the vertical axis is between 0 degrees and a maximum angle amax of 45 degrees, preferably between 30 degrees and 40 degrees, preferably substantially equal to 36 degrees.
Ces plages de valeurs et valeurs de l'angle d'inclinaison a ont été identifiées comme optimales pour :  These ranges of values and values of the angle of inclination a have been identified as optimal for:
- d'une part éloigner suffisamment les parties principales d'horizontale (42) de l'axe longitudinal pour conférer à l'ensemble une stabilité satisfaisante, notamment en termes de gite, - d'autre part, adapter la position sur l'axe vertical de la partie principale d'horizontale (42), de manière à ce que lors du déploiement de l'aile hors du bateau, la partie horizontale de l'aile soit plongée profondément dans l'eau et permette ainsi, si on le désire, de soulever la carène du bateau au-dessus de la surface moyenne de l'eau mais aussi au-dessus des vagues, de manière à obtenir une navigation calme.  on the one hand, to sufficiently distance the main horizontal parts (42) from the longitudinal axis in order to give the assembly a satisfactory stability, in particular in terms of housing, on the other hand, to adapt the position on the axis; vertical of the main part of horizontal (42), so that when deploying the wing out of the boat, the horizontal part of the wing is dipped deep into the water and thus allows, if desired , to raise the hull of the boat above the average surface of the water but also above the waves, so as to obtain a calm navigation.
Cet aspect d'angle optimisé peut être combiné avec les autres aspects décrits dans ce texte, ou mis en œuvre séparément voire isolément.  This optimized angle aspect can be combined with the other aspects described in this text, or implemented separately or in isolation.
Par ailleurs, la partie principale d'horizontale (42) de l'aile déployée est de préférence positionnée sur l'axe vertical entre 10 cm en-dessous et 5 cm au-dessus du centre (C sur la représentation de la figure 6) de l'hélice du moteur (20). En particulier, la partie principale d'horizontale (42) de l'aile déployée peut être située au même niveau sur l'axe vertical que le centre de l'hélice du moteur (20). Ceci est valable pour les deux ailes qui, rappelons-le, sont typiquement déployées en simultanément et de la même manière, des deux côtés du bateau. Furthermore, the main horizontal portion (42) of the deployed wing is preferably positioned on the vertical axis between 10 cm below and 5 cm above the center (C in the representation of Figure 6) of the engine propeller (20). In particular, the main horizontal portion (42) of the deployed wing may be located at the same level on the vertical axis as the center of the propeller motor (20). This is valid for both wings which, remember, are typically deployed simultaneously and in the same way on both sides of the boat.
Ainsi, l'hélice (qui agit dans l'eau pour propulser) et la partie principale d'horizontale (42) (qui agit dans l'eau pour générer de la portance) sont sensiblement à la même profondeur et travaillent simultanément, quelle que soit le soulèvement du bateau du fait de la portance des ailes, et la partie principale d'horizontale (42) est suffisamment basse pour assurer des caractéristiques de portance satisfaisantes, sans que l'hélice soit susceptible de sortir de l'eau lorsque le bateau (100) est au moins partiellement soulevé par les surfaces portantes.  Thus, the propeller (which acts in water to propel) and the main horizontal part (42) (which acts in the water to generate lift) are at substantially the same depth and work simultaneously, whatever the lifting of the boat due to the lift of the wings, and the main part of the horizontal (42) is low enough to ensure satisfactory lift characteristics, without the propeller is likely to come out of the water when the boat (100) is at least partially lifted by the bearing surfaces.
Cet aspect de concordance des profondeurs de l'hélice et de la partie principale d'horizontale peut être combiné avec les autres aspects décrits dans ce texte, ou mis en œuvre séparément voire isolément.  This aspect of concordance of the depths of the helix and the main part of the horizontal can be combined with the other aspects described in this text, or implemented separately or even separately.
L'horizontale et la verticale sont reliées par un coude arrondi.  The horizontal and the vertical are connected by a rounded elbow.
L'épaisseur de l'aile (40) peut être de l'ordre de 10 mm à 40 mm, de préférence d'environ 20 mm. La corde moyenne de l'aile (40) peut être comprise entre 100 mm et 500 mm, de préférence d'environ 300 mm. Lorsque le bateau est soulevé par les ailes (40), la longueur immergée d'une aile (40) (L sur la représentation de la figure 6) peut être comprise entre 600 mm et 1200 mm, de préférence d'environ 900 mm. La surface portante d'une aile (40) présentant une longueur immergée de 900 mm et une corde moyenne de 300 mm est de 54 dm2. The thickness of the wing (40) can be of the order of 10 mm to 40 mm, preferably of about 20 mm. The middle cord of the wing (40) can be between 100 mm and 500 mm, preferably about 300 mm. When the boat is lifted by the wings (40), the immersed length of a wing (40) (L in the representation of Figure 6) may be between 600 mm and 1200 mm, preferably about 900 mm. The bearing surface of a wing (40) having a submerged length of 900 mm and an average rope of 300 mm is 54 dm 2 .
Les ailes (40) sont situées au niveau de l'emménagement (17) du bateau (100), sur l'axe longitudinal. De part et d'autre de l'axe longitudinal au niveau de l'emménagement (17), la coque (1 3) du bateau (1 00) est percée d'un puits (32) qui épouse la section de la verticale de l'aile (40). Chaque aile (40) est destinée à coulisser dans le puits (32) entre la position rangée et la position déployée.  The wings (40) are located at the location (17) of the boat (100), on the longitudinal axis. On either side of the longitudinal axis at the level of the move (17), the hull (1 3) of the boat (1 00) is pierced by a well (32) which follows the section of the vertical of the wing (40). Each wing (40) is intended to slide in the well (32) between the stored position and the deployed position.
De préférence, le puits (32) débouche dans sa partie inférieure dans la partie périphérique du fond rigide du bateau et à proximité du boudin (1 1 ), afin de ne pas interférer avec le remorquage du bateau (100) sur une remorque de route lorsque les ailes (40) sont en position rangée. Le remorquage sur route s'en trouve ainsi facilité. L'angle d'inclinaison de la partie rectiligne de verticale (43) par rapport à l'axe vertical peut aussi contribuer à faciliter untel remorquage, en écartant les ailes de la remorque qui sera placée sous le bateau. Et cette inclinaison contribue par ailleurs à ce que les ailes traversent la coque rigide dans sa partie périphérique. Preferably, the well (32) opens in its lower part in the peripheral part of the rigid bottom of the boat and close to the flange (1 1), so as not to interfere with the towing of the boat (100) on a road trailer when the wings (40) are in the stowed position. The road towing is thus facilitated. The angle of inclination of the rectilinear portion of vertical (43) relative to the vertical axis can also help facilitate towing, by removing the wings of the trailer to be placed under the boat. And this inclination also contributes to the wings passing through the rigid shell in its peripheral portion.
Cet aspect de facilité de remorquage peut être combiné avec les autres aspects décrits dans ce texte, ou mis en œuvre séparément voire isolément.  This aspect of towing facility can be combined with the other aspects described in this text, or implemented separately or in isolation.
Par ailleurs, l'aménagement 17 comprend dans sa partie inférieure un caisson 170 (creux, voire plein) qui peut constituer par exemple le poste ou le siège de pilotage pour le pilote (le reste de l'emménagement pouvant comprendre les commandes moteur, le volant, un pare-brise, etc. ).  Furthermore, the arrangement 17 comprises in its lower part a box 170 (hollow or full) which can be for example the station or the pilot's seat for the pilot (the rest of the move may include the engine controls, the steering wheel, windshield, etc.).
Un logement 1700 est formé dans cette partie 170 de l'emménagement (17) de part et d'autre de l'axe longitudinal. Deux logements 1700 sont ainsi formés dans les parois opposées de la partie basse 170 de l'aménagement, de chaque côté de cet aménagement.  A housing 1700 is formed in this part 170 of the move (17) on either side of the longitudinal axis. Two dwellings 1700 are thus formed in the opposite walls of the lower part 170 of the layout, on each side of this arrangement.
Pour chaque logement : le logement est un trou qui permet au foil de traverser la paroi de la partie 170, le contour de ce trou épousant la section de la partie rectiligne de verticale (43) de l'aile qui est associée à ce logement, afin de pouvoir la guider en coulissement lors de son escamotage pour rangement, et de son déploiement.  For each housing: the housing is a hole that allows the foil to cross the wall of the portion 170, the contour of this hole conforming to the section of the rectilinear vertical portion (43) of the wing which is associated with this housing, in order to be able to guide it in sliding during its retraction for storage, and its deployment.
Le foil est en effet escamoté à l'intérieur de la partie basse 170, lors de son rangement. Plus précisément, la partie « verticale » du foil est au moins partiellement escamotée à l'intérieur de la partie basse 170, lors de ce rangement.  The foil is indeed retracted inside the lower part 170, during storage. More specifically, the "vertical" part of the foil is at least partially retracted inside the lower part 170, during this storage.
Ceci permet de réduire l'encombrement du foil, par son escamotage astucieux à l'intérieur d'une structure qui existe de toutes façons sur les semi rigides (structure telle qu'un poste de pilotage, ou un siège de pilotage par exemple).  This reduces the size of the foil, by its clever retraction within a structure that exists in any case on semi rigid (such as a cockpit, or a steering seat for example).
La hauteur de la partie basse 170 est limitée (en tout état de cause elle est en effet limitée par la hauteur de l'emménagement 17), elle-même limitée par la contrainte de visibilité du pilote. Cette limitation limite en conséquence la course du foil vers le haut. Sur la figure 7 les deux foils sont représentés complètement rangés (escamotés), et on voit que leur extrémité haute bute contre (ou est très proche de) la paroi horizontale supérieure 171 de la partie basse 170 (sur la figure 7 cette paroi supérieure est de forme concave). The height of the lower part 170 is limited (in any case it is indeed limited by the height of the moving 17), itself limited by the visibility constraint of the driver. This limitation therefore limits the foil stroke upwards. In FIG. 7, the two foils are represented completely stored (retracted), and it is seen that their upper end abuts (or is very close to) the upper horizontal wall 171 of the lower part 170 (in FIG. concave shape).
Les logements 1700 peuvent être non pas de simple trous traversant les parois de la partie 170, mais des conduits creux ouvrant ces parois et guidant les foils jusqu'au fond du conduit (ce fond se trouvant nécessairement en dessous de la face inférieure de la paroi 171 ).  The housings 1700 may not be simple holes through the walls of the part 170, but hollow ducts opening these walls and guiding the foils to the bottom of the duct (this bottom necessarily being below the underside of the wall 171).
De préférence, les puits (32) et les logements présentent un angle d'inclinaison correspondant à l'angle d'inclinaison entre la partie rectiligne de verticale (43) et l'axe vertical. Ainsi, l'encombrement des ailes (40) est minimisé par leur coulissement dans les puits (32) et dans les logements de l'emménagement (17) entre une position rangée, dans laquelle l'extrémité de la verticale de l'aile (40) est en butée contre la partie supérieure du logement, et une position déployée, dans laquelle l'extrémité de la verticale de l'aile affleure au niveau de la partie supérieure du puits (32) formé dans la coque (1 3). La longueur de la verticale de l'aile (40) résulte de la profondeur du logement, donc de la hauteur de l'emménagement (17) et de l'angle d'inclinaison de la partie rectiligne de verticale (43). La longueur de la verticale peut avantageusement être comprise entre 500 mm et 1500 mm, avantageusement autour de 1000 mm.  Preferably, the wells (32) and the housings have an angle of inclination corresponding to the angle of inclination between the rectilinear vertical portion (43) and the vertical axis. Thus, the size of the wings (40) is minimized by their sliding in the wells (32) and in the accommodation housing (17) between a stowed position, in which the end of the vertical of the wing ( 40) is in abutment against the upper part of the housing, and an extended position, in which the end of the vertical of the wing is flush with the level of the upper part of the well (32) formed in the shell (1 3). The length of the vertical of the wing (40) results from the depth of the housing, therefore the height of the move (17) and the angle of inclination of the rectilinear vertical portion (43). The length of the vertical may advantageously be between 500 mm and 1500 mm, advantageously around 1000 mm.
La figure 3a représente le mécanisme d'asservissement (31 ) d'actionnement et de verrouillage de l'aile sur la coque de bateau. Un travail de seconde monte ou de première monte est réalisé en perçant la coque d'un puits (32) qui épouse la section de l'aile, logeant le dispositif d'asservissement (31 ) qui actionne et qui verrouille l'aile depuis et dans une position basse ou haute. Le dispositif d'asservissement est solidarisé à un boîtier de protection (30) qui protège le passage de l'aile et le mécanisme d'asservissement (31 ). Ce boitier de protection (30) est repris aux éléments structurels du bateau, plancher, livet et carlingue par reprise de stratification, collage et/ou boulonnage. Notamment, le boîtier de protection (30) est repris par un ancrage qui s'appuie par reprise dans le triangle formé entre le livet (14), la coque (13) et la carlingue (12). Le boîtier de protection (30) présente une surface supérieure sensiblement plane, orientée selon un angle qui peut correspondre à l'angle de la partie rectiligne de verticale (43). Ainsi, le boîtier de protection (30) loge le mécanisme d'asservissement (31 ) et la verticale de l'aile (40), tout en reconstituant un plancher oblique. L'encombrement de l'aile (40) et de son mécanisme d'asservissement (31 ) est donc minimal et la sécurité est assurée pour les personnes naviguant sur le bateau (100). Figure 3a shows the servo mechanism (31) for actuating and locking the wing on the boat hull. A work of second-level or original equipment is performed by piercing the hull of a well (32) which marries the section of the wing, housing the servo device (31) which actuates and which locks the wing since and in a low or high position. The servo device is secured to a protective housing (30) which protects the passage of the wing and the servo mechanism (31). This protective case (30) is taken from the structural elements of the boat, floor, livet and cabin by resumption of lamination, gluing and / or bolting. In particular, the protective case (30) is taken up by an anchor which rests in the triangle formed between the livet (14), the hull (13) and the cabin (12). The protective case (30) has a substantially flat upper surface oriented at an angle which may correspond to the angle of the straight vertical portion (43). Thus, the protective housing (30) houses the servo mechanism (31) and the vertical wing (40) while restoring an oblique floor. The size of the wing (40) and its servo mechanism (31) is minimal and safety is ensured for people sailing on the boat (100).
Le dispositif d'asservissement (31 ) permet trois choses : 1 - le verrouillage en position 2 - la mise en translation 3 - un mouvement de rotation pour régler l'angle de l'aile dans l'eau. Le mécanisme d'asservissement (31 ) permet d'effectuer ces trois choses de manière simultanée et symétrique pour chaque aile (40).  The servo device (31) allows three things: 1 - the locking position 2 - the translation 3 - a rotational movement to adjust the angle of the wing in the water. The servo mechanism (31) makes it possible to perform these three things simultaneously and symmetrically for each wing (40).
Les figures 5a et 5b représentent une vue de haut de deux dispositions d'appui de jeux d'ailes avant / arrière selon l'invention avec un jeu avant d'aile bâbord et tribord qui se positionne à la hauteur de l'emménagement (17) et une aile arrière (50) montée sur l'arbre du moteur arrière (20) figure 5a, ou par un jeu d'aile arrière bâbord et tribord (50) montées en quelque sorte en parallèle du jeu d'ailes avant.  FIGS. 5a and 5b show a top view of two front / rear wing play support arrangements according to the invention with a port and starboard wing forward play which is positioned at the height of the moving-in (17 ) and a rear wing (50) mounted on the rear engine shaft (20) Figure 5a, or by a port and starboard rear wing clearance (50) mounted somewhat parallel to the set of front fenders.
L'aile arrière (50) peut avantageusement présenter une surface portante projetée sur un plan horizontal participant pour entre 10% et 30% à la portance totale du bateau (100), de préférence participant à hauteur d'environ 20% de la portance totale. Le jeu d'ailes (40) avant participe quant à lui pour entre 70% et 90% de la portance totale. Par exemple, pour un bateau dont la surface portante des ailes (40) est de 54 dm2, la surface portante du plan porteur arrière pourra être de l'ordre de 15 dm2. Un tel bateau (100) peut présenter une vitesse de décollage de l'ordre de 15 kts. The rear wing (50) may advantageously have a bearing surface projected on a horizontal plane participating for between 10% and 30% to the total lift of the boat (100), preferably participating at about 20% of the total lift . The set of wings (40) before participates for between 70% and 90% of the total lift. For example, for a boat whose bearing surface wings (40) is 54 dm 2 , the bearing surface of the rear carrier plane may be of the order of 15 dm 2 . Such a boat (100) can have a take-off speed of the order of 15 kts.
La présente invention concerne donc un ensemble portant de bateau semi rigide comprenant une coque (1 3), une carlingue (12), un plancher (P) et ses livets (14), des boudins latéraux et proue (1 1 ), un emménagement (17), un moteur arrière (20) caractérisé en ce que pour une portance avant, côté bâbord et tribord au niveau de l'emménagement (17) la coque (13) est percée d'un puits (32) qui laisse passer une aile (40) asservie en blocage translation et rotation par un mécanisme d'asservissement (31 ) monté dans un boîtier de protection (30) repris aux éléments structurels du bateau, plancher, livet (14) et carlingue (12), par reprise de stratification, collage et/ou boulonnage, l'aile comprend un partie horizontale avec une extrémité bout d'aile à boudin (41 ) dont la forme incurvée épouse la forme du boudin, et une verticale d'aile qui comprend une extrémité de verticale (44) qui s'incurve vers le centre du bateau, et pour une portance arrière, une aile est montée sur l'arbre moteur du moteur arrière (20). The present invention therefore relates to a semi-rigid boat carrying assembly comprising a hull (1 3), a cabin (12), a floor (P) and its livettes (14), side and bow thrusters (1 1), a moving-in (17), a rear engine (20) characterized in that for front lift, side port and starboard at the level of the arrangement (17) the hull (13) is pierced by a well (32) which allows a wing (40) to pass therethrough in translational locking and rotation by a servo mechanism (31) mounted in a protective casing (30) taken from the structural elements of the boat, floor, livet (14) and cabin (12), by resumption of lamination, gluing and / or bolting, the wing comprises a horizontal part with a tip end d flange wing (41) whose curved shape matches the shape of the flange, and a wing vertical which comprises a vertical end (44) which curves towards the center of the boat, and for a rear lift, a wing is mounted on the motor shaft of the rear motor (20).
La présente invention concerne donc un ensemble portant de bateau semi rigide caractérisé en ce que la portance arrière est une aile portante montée sur l'arbre moteur du moteur arrière (20).  The present invention therefore relates to a semi-rigid boat carrying assembly, characterized in that the rear lift is a load-bearing wing mounted on the rear engine motor shaft (20).
La présente invention concerne donc un ensemble portant de bateau semi rigide caractérisé en ce que la portance arrière comprend un jeu d'aile arrière bâbord et tribord (50) montées à l'arrière du bateau en parallèle du jeu d'ailes avant.  The present invention thus relates to a semi-rigid boat carrying assembly characterized in that the rear lift comprises a port and starboard rear wing clearance (50) mounted at the rear of the boat in parallel with the set of front fenders.
On voit bien que de nombreuses variantes éventuellement susceptibles de se combiner peuvent ici être apportées sans jamais sortir du cadre de l'invention tel qu'il est défini ci-après.  It is clear that many variants may possibly be combined here can be made without ever departing from the scope of the invention as defined below.
