Abstract

The invention relates to a hull assembly (30) of an outboard boat (30) having a motor (10) with a propeller (11) and a one-piece hydrofoil (40), characterised in that the rear of the hull (30), close to the motor, forms a step (20) from port side to starboard side, of the same volume as that of the wing (44) of a one-piece hydrofoil (40) which is actuated by a motor-driven actuating mechanism (46), in a vertical translation movement, by two hydrofoil arms (42a, 42b) that slide in two side trunks (41a, 41b) formed in the thickness of the hull, in order to fit closely in a first hydrofoil storage position (40) pulled back against the hull, in which the entirety of the hull is smooth, and a second flight position in which the wing of the hydrofoil is positioned beneath the motor propeller (11) for the column of water circulating beneath the hull, which is sucked up by the propeller (11).

Description

Aile rétractable par coopération de coque à redan et foil monobloc  Retractable wing by redan hull cooperation and monoblock foil
La présente invention concerne une structure complète d’accueil et d’actionnement de foil arrière bord à bord monobloc rétractable pour bateau à moteur. Le bateau à moteur peut être à coque rigide ou semi rigide, à motorisation hors-bord comme embarquée. Par foils il est entendu, ces ailes dont l’hydrodynamique donne de la portance au bateau. Par bord à bord monobloc il est entendu un foil unique pour portance de bâbord à tribord sous le bateau. Par foil rétractable, il est entendu un foil qui soit actionnable en translation sous l’eau pour le descendre ou le remonter par rapport au niveau de la coque.  The present invention relates to a complete structure for receiving and actuating foil rear edge to edge monoblock retractable motor boat. The motorboat can be rigid or semi rigid, with outboard engine as shipped. By foils it is understood, these wings whose hydrodynamics gives lift to the boat. By edge to edge monoblock it is understood a single foil for port to starboard portage under the boat. By retractable foil, it is understood a foil that is operable in translation under water to lower it or raise it relative to the level of the hull.
Il est connu des façons de structurer des foils sur des bateaux à voile. Il est très peu connu de structuration de foils sur des bateaux à moteurs. La présente invention vise à répondre à un cas très particulier qui n’a jusqu’alors jamais été abordé qui est celui de la structuration d’un foil arrière rétractable bord à bord monobloc de bateau à moteur. En effet, l’invention répond à un nouveau jeu de contraintes jamais résolues jusqu’alors qui est 1 - de proposer un foil arrière bord à bord rétractable pour bateau à moteur qui puisse répondre à un jeu de contraintes différents selon que le bateau se trouve sur une hauteur d’eau importante qui permet alors de descendre le foil, ou sur qui s’approche d’un haut fond ou du bord et qui nécessite de remonter le foil. 2 - de proposer un foil aux performances mécaniques et hydrodynamiques optimisées. En effet il existe des foils soit sur le côté du bateau (bâbord ou tribord) soit au centre du bateau, mais qui présentent l’inconvénient de présenter des extrémités saillantes latérales en bout d’aile qui dans l’eau créent de la cavitation et nuisent aux performances du bateau. Plus particulièrement, lorsque la jonction de la partie horizontale du foil avec la partie verticale n’est pas en bout d’aile, alors cela génère des perturbations hydrodynamiques. L’idée est de proposer un foil qui sans bout d’aile latérale. Typiquement l’invention innove en proposant un foil dit en U ou en V bord à bord sous le bateau qui se rétracte pour s’adapter à la hauteur de fond et aux conditions de navigation. 3 - le positionnement de foils à l’arrière du bateau apporte une forte complexité pour conjuguer la poussée du moteur à la présence des foils. La position du moteur ne doit pas interférer à celle des foils et inversement. Cela est très difficile dans la mesure où selon les conditions de navigation, un appui arrière mal dimensionné vient totalement perturber les performances et la maniabilité du bateau. There are known ways to structure foils on sailing boats. There is very little known structuring of foils on motor boats. The present invention aims to respond to a very particular case which has hitherto never been discussed which is that of structuring a foil rear retractable edge to edge monobloc motor boat. Indeed, the invention responds to a new set of previously unresolved constraints that is 1 - to provide a retractable rear edge-to-edge foil for motor boat that can respond to a set of different constraints depending on whether the boat is located on a significant height of water which then allows to lower the foil, or on which approaches a high bottom or the edge and which requires to raise the foil. 2 - to propose a foil to optimized mechanical and hydrodynamic performance. Indeed there are foils either on the side of the boat (port or starboard) or in the center of the boat, but have the disadvantage of having lateral projecting ends at the end of the wing which in the water create cavitation and adversely affect the performance of the boat. More particularly, when the junction of the horizontal part of the foil with the vertical part is not at the end of the wing, then this generates hydrodynamic disturbances. The idea is to propose a foil without side wing tip. Typically the invention innovates by proposing a foil said U or V edge to edge under the boat that retracts to adapt to the background height and navigation conditions. 3 - the positioning of foils at the rear of the boat brings a high complexity to combine the thrust of the engine with the presence of foils. The position of the motor must not interfere with that of the foils and vice versa. This is very difficult to the extent that depending on the navigation conditions, poorly sized rear support completely disrupts the performance and handling of the boat.
Un objet principal de l’invention est donc d’améliorer les performances hydrodynamiques des foils pour bateau à moteur.  A main object of the invention is therefore to improve the hydrodynamic performance of foils for motor boats.
Un objet de l’invention est de proposer un système complet adapté qui optimise l’ensemble des performances du bateau à moteur selon qu’il soit en condition de navigation pleine eau comme proche du fond. Un objet de l’invention est de proposer une solution robuste, économique et facile à manœuvrer. An object of the invention is to provide a complete adapted system that optimizes the performance of the motor boat according to whether it is in full water navigation condition as close to the bottom. An object of the invention is to provide a robust, economical and easy to maneuver.
Un objet de l’invention est de proposer une solution qui simplifie la fabrication des foils.  An object of the invention is to provide a solution that simplifies the manufacture of foils.
Dans un aspect principal, l’invention propose une modification de la structure des bateaux par action sur la coque afin de laisser la place à une structure de foils et son mécanisme d’actionnement. L’invention est une invention de première monte est n’est pas adaptée pour une seconde monte à date. L’invention propose une série de modifications et d’ajouts innovants sur le fond de coque, sur les bords de coque, qui coopère à la fois avec un foil de conception innovante, et avec un dispositif d’actionnement lui- même innovant.  In a main aspect, the invention proposes a modification of the structure of the boats by action on the hull in order to leave room for a foil structure and its actuating mechanism. The invention is an invention of original equipment is not suitable for a second date to date. The invention proposes a series of innovative modifications and additions to the shell bottom, on the shell edges, which cooperates both with an innovative design foil, and with an actuating device itself innovative.
Dans un aspect de G invention, le foil arrière adopte donc une forme générale en U avec deux bras verticaux qui sont les côtés du U, et une aile portante qui épouse la forme de la coque du bateau.  In one aspect of the invention, the rear foil thus adopts a generally U-shaped shape with two vertical arms which are the sides of the U, and a load-bearing wing which matches the shape of the hull of the boat.
Dans un aspect l’invention propose des aménagements spécifiquement réalisés pour permettre sa rétractabilité. Sur le pont, des coffres structurels sont disposés de chaque côtés au niveau des bras verticaux, suffisamment hauts et profonds pour contenir ces verticaux de foils en position haute au repos et en position basse en charge, en travail. Dans un aspect de l’invention, les mécanismes de montée et de descente se trouvant également dans ces coffres. In one aspect the invention provides arrangements specifically made to allow its retractability. On the deck, structural boxes are arranged on each side at the vertical arms, sufficiently high and deep to contain these vertical foils in the high position at rest and in the low position under load, in work. In one aspect of the invention, the raising and lowering mechanisms are also in these chests.
Dans un aspect de l’invention sous la coque, un décaissement, couramment dénommé redan, dans la surface plane de glisse est réalisé, afin que le foil vienne s’emboîter sans se trouver en sur épaisseur dépassant de la coque une fois au repos. Ainsi les éléments structurels de pont et de coque ont subi une adaptation spécifique à l’ajout du foil.  In one aspect of the invention under the hull, a disbursement, commonly referred to as redan, in the flat sliding surface is carried out, so that the foil comes to fit without being in thickness beyond the hull once at rest. Thus the structural elements of deck and hull have undergone a specific adaptation to the addition of the foil.
Les figures annexées représentent un mode particulier de l’invention sur lesquelles : The appended figures represent a particular embodiment of the invention in which:
- La figure 1 représente un bateau hors-bord traditionnel  - Figure 1 shows a traditional outboard boat
- Les figures 2a, 2b, 2c représentent trois vues successives de profil du bateau hors-bord équipé de la présente invention  FIGS. 2a, 2b and 2c show three successive profile views of the outboard boat equipped with the present invention

- La figure 4a représente une vue de profil de la dite coque équipée de coffres de bras de foils FIG. 4a represents a side view of said shell equipped with foil arm boxes
- La figure 4b représente une vue de profil de la dite coque équipée de l’ensemble de l’invention  FIG. 4b represents a side view of said shell equipped with the assembly of the invention
- Les figures 5a à 5d représentent une vue de profil des différents profils de foils selon l’invention La figure 1 représente un bateau hors-bord traditionnel en vue de côté avec sa coque (30) et à l’arrière du bateau un moteur (10) à hélice (11). FIGS. 5a to 5d show a profile view of the various foil profiles according to the invention Figure 1 shows a traditional outboard boat in side view with its hull (30) and at the rear of the boat a motor (10) propeller (11).
Les figures 2a, 2b, 2c représentent trois vues successives de profil du bateau hors-bord équipé de la présente invention. Il apparaît en figure 2a, comment la coque est dessinée pour former un redan (20) qui est un léger décrochage de façon à ce qu’une fois équipé du foil (40) en LF, figure 2b, l’ensemble constitué présente une surface de coque totalement lisse. En bref, le redan adopte en creux le volume du foil qui vient s’encastrer sous la coque dans le redan pour présenter au final une surface de coque + foil qui soit lisse. De cette façon, lorsque le foil (40) n’est pas abaissé, la qualité de glisse et d’hydrodynamique de la coque n’est pas altérée. Plus particulièrement le redan est dessiné à l’arrière de la coque sur un ruban. Cette disposition optimise la facilité de la coque qui après le redan vient donc former le tableau arrière du bateau. La figure 2c montre comment le foil (40) en position baissée vient se positionner devant l’hélice et sous l’hélice. En bref, le foil laisse la place à une section d’eau pour passer entre la coque et le foil (40) pour être aspirée et propulsée dans l’hélice.  Figures 2a, 2b, 2c show three successive profile views of the outboard boat equipped with the present invention. It appears in Figure 2a, how the shell is designed to form a redan (20) which is a slight stall so that once equipped foif (40) LF, Figure 2b, the assembly has a surface completely smooth shell. In short, the redan adopts in hollow the volume of the foil which is encased under the shell in the redan to present in the end a surface of shell + foil which is smooth. In this way, when the foil (40) is not lowered, the quality of glide and hydrodynamics of the hull is not impaired. More particularly, the redan is drawn on the back of the hull on a ribbon. This arrangement optimizes the ease of the hull which after the redan therefore form the transom of the boat. Figure 2c shows how the foil (40) in the lowered position is positioned in front of the propeller and under the propeller. In short, the foil leaves room for a section of water to pass between the shell and the foil (40) to be sucked and propelled into the propeller.
La figure 3 représente une vue de section de coque de bateau traditionnelle avec - une longueur L1 de maître bau, à savoir la largeur hors tout de la coque au niveau du pont - une longueur L2 de franc bord, à savoir la hauteur des côtés de la coque, du pont jusqu’au point de courbure avec le fond de la coque - une longueur L3 de tirant d’eau, à savoir la distance entre la ligne de flottaison au repos et le point de coque le plus profond. L’invention présente des proportions très particulières que nous tenons ici à décrire puisque la recherche de nouveau rapport de proportion permet de mettre en place l’invention qui n’était absolument pas évidente à implanter à un homme du métier. Plus particulièrement FIG. 3 represents a traditional hull sectional section view with a length L1 of master beam, namely the overall width of the hull at deck level, a length L2 of freeboard, to the height of the sides of the hull, from the deck to the point of curvature with the bottom of the hull - a length L3 of draft, namely the distance between the waterline at rest and the hull point deeper. The invention has very particular proportions that we wish to describe here since the search for a new proportion ratio makes it possible to implement the invention which was absolutely not obvious to implant to a person skilled in the art. More particularly
La longueur totale des bras verticaux (42a, 42b) de foil est comprise entre 0,5 et 1 ,5 fois la hauteur L2 du franc bord. - La longueur des bras verticaux (42a, 42b) de foil en appuis dans la coque, avec le foil descendu en travail est comprise entre 0,2 et 0,5 fois la hauteur L2 du franc bord.  The total length of the vertical arms (42a, 42b) of foil is between 0.5 and 1.5 times the height L2 of the freeboard. - The length of the vertical arms (42a, 42b) of foil supported in the hull, with the foil lowered into work is between 0.2 and 0.5 times the height L2 of the freeboard.
- La longueur des bras verticaux (42a, 42b) de foil en extérieur de coque, en travail avec le foil descendu est comprise entre 1 et 0,5 fois la hauteur L2 du franc bord.  - The length of the vertical arms (42a, 42b) foil outside hull, working with the foil down is between 1 and 0.5 times the height L2 of the freeboard.
- L’écartement des bras verticaux de foil est compris entre 0,5 et 1 fois la longueur L1 du maître bau.  - The spacing of the vertical arms of foil is between 0.5 and 1 times the length L1 of the master bau.
- La longueur en développé du plan horizontal de foil est compris entre 0,5 et 1,5 fois la longueur en développé du fond de coque dans le sens latéral. - Le tirant d’eau foil remonté, hors autres appendices tels que le moteur et autres foils différents est identique au tirant d’eau sans les foils - The developed length of the horizontal foil plane is between 0.5 and 1.5 times the developed length of the shell bottom in the lateral direction. - The draft foil reassembled, excluding other appendages such as engine and other foils different is identical to the draft without the foils
- Le tirant d’eau foil descendu, hors autres appendices tels que le moteur et autres foils différents est compris entre la hauteur de tirant d’eau foil remonté + 0,5 à 1,3 fois la hauteur du franc bord. - The lowered foil draft, excluding other appendages such as the engine and other foils different is between the draft pitch foil raised + 0.5 to 1.3 times the height of the freeboard.
La figure 4a représente une vue de profil de la dite coque équipée de coffres (41a, 41b) de bras de foils. Ils logent à bâbord et à tribord les bras de foils (42a, 42b) bâbord et à tribord et permettent la translation des bras de foils sans que cette translation risque de blesser un passager ou risque d’être gênée par un obstacle quelconque. Figure 4a shows a side view of said shell equipped with boxes (41a, 41b) foil arms. They accommodate port and starboard arms foil (42a, 42b) port and starboard and allow the translation of the foil arms without this translation may injure a passenger or risk being hindered by any obstacle.
La figure 4b représente une vue de profil de la dite coque équipée de l’ensemble de l’invention avec les bras de foils (42a, 42b) logés dans les coffres de foils (41a, 41b). Un système d’actionnement (46) comprenant une motorisation, un calculateur et des moyens de mises en déplacement du type chariot sur chaîne ou sangle sur poulie transmettent les mises en translation des bras de foils vers le bas ou vers le haut selon les instructions du calculateur qui reçoit lui-même les instructions du pilote depuis le tableau de bord. La descente des deux bras est coordonnée par un mécanisme de coordination. Le foil monobloc comprend donc deux bras latéraux (42a, 42b) sensiblement verticaux, et une aile sensiblement horizontale en coupe en forme de U, figure 5d, ou de V, figure 5c. Préférentiellement le corps monobloc ne présente aucune surface d’arrêt saillante latérale dans le plan de coupe, ce qui fait que préférentiellement figure 5b, les bras sont dans le prolongement de l’extrémité de l’aile, plutôt que de se rapporter comme des bifurcations qui laisseraient une extrémité d’aile saillante former prise à la cavitation hydrodynamique, figure 5a. FIG. 4b represents a side view of said shell equipped with the assembly of the invention with the foil arms (42a, 42b) housed in the foil boxes (41a, 41b). An actuation system (46) comprising a motor, a calculator and means for moving the carriage-type on a chain or pulley strap transmit the translation of the foil arms downwards or upwards according to the instructions of the calculator which itself receives the instructions of the pilot from the dashboard. The descent of both arms is coordinated by a coordination mechanism. The monoblock foil thus comprises two lateral arms (42a, 42b) substantially vertical, and a substantially horizontal section U-shaped, Figure 5d, or V, Figure 5c. Preferably, the one-piece body has no lateral projecting stop surface in the plane of section, so that preferentially FIG. 5b, the arms are in the extension of the end of the wing, rather than being referred to as bifurcations. which would leave a protruding wing tip forming a hydrodynamic cavitation, Figure 5a.
