Description
Bateau moteur à foils rétractables présentant une configuration dissymétrique en position passive Motorboat with retractable foils having an asymmetrical configuration in the passive position
Domaine de l'invention La présente invention concerne les bateaux motorisés à foils. Field of the Invention The present invention relates to motorized foil boats.
Etat de la technique State of the art
Le principe consistant à assurer l'équilibrage du poids d'un bateau par un effet de portance hydrodynamique produit par la vitesse de l'eau agissant sur des éléments en forme d'ailes immergées, semi-immergées ou traversant la surface de l'eau, par opposition à la seule utilisation de l'effet archimédien des volumes immergés, est relativement ancien. Dès le début du vingtième siècle il existe des bateaux à moteur équipés de ce genre de dispositif nommé foil. On connaît par ailleurs l'utilisation de foils dans le but de stabiliser en roulis ou en tangage des navires en configuration archimédienne. L'utilisation de foils améliore la performance des bateaux par l'augmentation de la vitesse et/ou la diminution de la consommation énergétique. The principle of balancing the weight of a boat by a hydrodynamic lift effect produced by the speed of the water acting on elements in the form of submerged wings, semi-submerged or crossing the surface of the water , as opposed to the only use of the Archimedean effect of submerged volumes, is relatively old. From the beginning of the twentieth century there are motor boats equipped with this kind of device named foil. We also know the use of foils in order to stabilize roll or pitch vessels in Archimedean configuration. The use of foils improves the performance of boats by increasing speed and / or reducing energy consumption.
Le brevet US 4 237 810 divulgue un bateau à moteur doté de foils. US Patent 4,237,810 discloses a motor boat with foils.
Sur ce bateau, et plus généralement sur les bateaux motorisés à foils, la position des foils par rapport à la structure porteuse ne varie pas, que le bateau soit à l'arrêt, se déplace à faible ou grande vitesse, que la force du vent ou la hauteur des vagues soit prononcée ou non. D'autres brevets, tels que le brevet US 3 241 51 1 , divulguent des principes de bateaux à moteur et à foils avec système de rétractabilité des foils, par coulissement vertical ou par mécanismes divers de rotation. Ces systèmes permettent notamment de réduire, au moins partiellement, l'encombrement et la traînée des appendices lorsqu'ils ne sont pas utilisés. On this boat, and more generally on motorized foil boats, the position of the foils relative to the load-bearing structure does not vary, whether the boat is at a standstill, moves at low or high speed, that the force of the wind where the height of the waves is pronounced or not. Other patents, such as US Pat. No. 3,241,511, disclose principles of motor and foil boats with foil retractability system, vertical sliding or various rotational mechanisms. These systems make it possible in particular to reduce, at least partially, the size and the drag of the appendages when they are not used.
La demande de brevet WO2016/0094090 divulgue un principe permettant de satisfaire deux configurations géométriques distinctes précises, à savoir (i) la coïncidence avec la forme de la coque des foils en position relevée, et (ii) le positionnement des foils en position basse qui permette d'obtenir naturellement l'autostabilité de l'hydrofoil en vol, que ce soit en roulis ou en tangage.
Les dispositifs de l'état de la technique ne permettent cependant pas que les foils soient à la fois au-dessus de la ligne de flottaison en position passive, intégrés de façon optimale dans la structure porteuse, et suffisamment écartés en position active, p. ex. d'au moins deux fois la largeur du bateau. Une telle disposition aurait le mérite d'augmenter la stabilité naturelle du bateau tout en minimisant l'encombrement des foils en position passive. The patent application WO2016 / 0094090 discloses a principle that makes it possible to satisfy two distinct distinct geometrical configurations, namely (i) the coincidence with the shape of the hull of the foils in the raised position, and (ii) the positioning of the foils in the low position which allows to obtain naturally the autostability of the hydrofoil in flight, whether in roll or in pitch. However, the devices of the state of the art do not allow the foils to be both above the waterline in passive position, optimally integrated in the supporting structure, and sufficiently spaced in the active position, e.g. ex. at least twice the width of the boat. Such a provision would have the merit of increasing the natural stability of the boat while minimizing the bulk of the foils in the passive position.
Description de l'invention Description of the invention
La présente invention offre notamment l'avantage de remédier au problème décrit dans le chapitre précédent. De manière générale, elle consiste à créer, pour une paire de foils donnée en position passive, une dissymétrie par rapport au plan médian vertical de la structure porteuse. The present invention offers the advantage of overcoming the problem described in the previous chapter. In general, it consists in creating, for a pair of foils given in a passive position, an asymmetry with respect to the vertical median plane of the supporting structure.
L'invention concerne plus précisément un bateau à moteur comprenant une structure porteuse et au moins une paire de foils similaires disposés de chaque côté de la structure porteuse, chacun desdits foils étant défini par une aile et son support; ce dernier étant rétractable dans la partie inférieure de la structure et monté coulissant par rapport à celle-ci ; lesdits foils étant disposés de manière à adopter au moins deux positions fixes, à savoir une position dite active dans laquelle ils sont déployés dans des positions similaires et une position dite passive dans laquelle lesdits supports sont rétractés dans la structure porteuse; caractérisé par le fait que dans la position passive, la disposition desdits foils est dissymétrique par rapport au plan médian vertical de la structure porteuse. The invention more specifically relates to a motor boat comprising a carrying structure and at least one pair of similar foils disposed on each side of the support structure, each of said foils being defined by a wing and its support; the latter being retractable in the lower part of the structure and slidably mounted relative thereto; said foils being arranged to adopt at least two fixed positions, namely a so-called active position in which they are deployed in similar positions and a so-called passive position in which said supports are retracted into the supporting structure; characterized in that in the passive position, the arrangement of said foils is asymmetrical with respect to the vertical median plane of the carrier structure.
En position passive, le positionnement des foils d'une même paire est donc dissymétrique. En position active, le positionnement des foils est symétrique, voire très faiblement dissymétrique mais sans que cela n'affecte la trajectoire du bateau. In the passive position, the positioning of the foils of the same pair is asymmetrical. In the active position, the positioning of the foils is symmetrical, or very weakly asymmetrical but without it affecting the trajectory of the boat.
La dissymétrie en position passive peut être obtenue de différentes manières. Les supports peuvent être symétriquement identiques mais disposés de manière dissymétrique en position passive. Dans ce cas de figure, les trajectoires des supports sont également dissymétriques. The dissymmetry in the passive position can be obtained in different ways. The supports may be symmetrically identical but asymmetrically arranged in a passive position. In this case, the trajectories of the supports are also asymmetrical.
Alternativement, les supports peuvent être dissymétriques, càd avoir des formes légèrement différentes. Alternatively, the supports may be asymmetrical, ie have slightly different shapes.
La dissymétrie est de préférence minimisée. Elle vise seulement à autoriser une rétraction des supports dans la structure porteuse, ces derniers se déplaçant en grande partie selon une trajectoire sensiblement parallèle au plan d'eau, afin d'obtenir un positionnement relativement éloigné des ailes par rapport à la structure porteuse.
Selon un mode réalisation de l'invention, en position passive, les supports sont superposés. Le mécanisme de coulissement des supports est de préférence incurvé. The asymmetry is preferably minimized. It only aims to allow a retraction of the supports in the support structure, the latter moving largely along a path substantially parallel to the body of water, to obtain a relatively distant positioning of the wings relative to the supporting structure. According to one embodiment of the invention, in the passive position, the supports are superimposed. The sliding mechanism of the supports is preferably curved.
Selon une variante particulièrement intéressante, la trajectoire des supports est constituée d'au moins deux parties, de courbures différentes, la partie la plus proche du plan médian vertical étant moins incurvée que la partie la plus éloignée. According to a particularly advantageous variant, the trajectory of the supports consists of at least two parts of different curvatures, the part closest to the vertical median plane being less curved than the farthest part.
La dissymétrie des foils permet une réalisation de la rétraction des foils novatrices dont les avantages sont : The dissymmetry of the foils allows a realization of the retraction of the innovative foils whose advantages are:
-Foils au-dessus de la flottaison en configuration passive le protégeant des dégradations (notamment algues ..) connu pour affecter considérablement les performances des hydrofoils -Foils above the floating in passive configuration protecting it from damage (including algae ..) known to significantly affect the performance of hydrofoils
-Foils rangés dans toute la largeur de la structure porteuse, permettant des foils plus grands pour une taille de bateau donné. Les foils plus grands une fois en position active sont plus écartés, améliorant sensiblement la stabilité de l'hydrofoil de première génération. -Fores arranged throughout the width of the supporting structure, allowing larger foils for a given boat size. The larger foils once in active position are further apart, significantly improving the stability of the first generation hydrofoil.
-Réduction de l'encombrement étant donné que les foils dans ce mode de rétraction peuvent être positionnés sous le pont du bateau. Reduced clutter since the foils in this mode of retraction can be positioned under the deck of the boat.
Selon un autre mode de réalisation de l'invention les foils sont guidés par deux cales adaptées en ce qu'elles permettent le passage de voiles de corde et vrillages évolutifs. Avantageusement le système de remontée mécanique des foils comporte un vérin à vis solidaire de structure porteuse et du foil simultanément. According to another embodiment of the invention the foils are guided by two shims adapted in that they allow the passage of rope sails and evolutionary twisting. Advantageously, the mechanical lift system of the foils comprises a screw jack secured to the carrier structure and the foil simultaneously.
De manière générale, la dissymétrie des foils décrites dans la présente demande de brevet peut être combinée avec toutes les autres caractéristiques décrites dans la demande de brevet WO 2016/009409, en particulier le mécanisme de déploiement/rétraction des foils et le simulateur dynamique. In general, the dissymmetry of the foils described in the present patent application can be combined with all the other characteristics described in the patent application WO 2016/009409, in particular the mechanism of deployment / retraction of the foils and the dynamic simulator.
La figure décrit un exemple de réalisation dans lequel les foils 2 sont similaires mais pas symétriquement identiques. Les supports 4 sont légèrement dissymétriques de manière à pouvoir être superposés dans la structure porteuse 1 en position passive. La figure illustre trois positions des foils 2,2',2", soit la position passive 2, une position transitoire 2' et la position active 2". En position passive, les ailes 3 se confondent avec les parois latérales de la structure porteuse 1. The figure describes an exemplary embodiment in which the foils 2 are similar but not symmetrically identical. The supports 4 are slightly asymmetrical so as to be superimposed in the carrier structure 1 in the passive position. The figure illustrates three positions foils 2,2 ', 2 ", the passive position 2, a transient position 2' and the active position 2". In passive position, the wings 3 merge with the side walls of the supporting structure 1.
En position active, la distance entre les extrémités des ailes 3" est au moins équivalente à deux fois la largeur de la structure porteuse 1.
Lors de la phase de déploiement les foils 2,2', 2" se déplacent initialement le long d'une trajectoire légèrement incurvée qui s'éloigne du plan médian vertical 5 de la structure porteuse 1 . S'en suit un basculement des foils 2',2" autour d'un axe 6 dirigé selon une direction parallèle à l'axe principal du bateau . Lors du basculement, l'extrémité libre 8 de chaque support 4 subit également une rotation autour de l'axe 6. In the active position, the distance between the ends of the wings 3 "is at least equivalent to twice the width of the supporting structure 1. During the deployment phase the foils 2,2 ', 2 "initially move along a slightly curved path that moves away from the vertical median plane 5 of the supporting structure 1. A tilting of the foils 2 follows. ', 2 "around an axis 6 directed in a direction parallel to the main axis of the boat. During tilting, the free end 8 of each support 4 is also rotated about the axis 6.
Il va de soi que l'invention ne se limite pas aux exemples décrits et illustrés dans le présent document. Elle couvre n'importe quel mécanisme permettant de modifier la position des foils pendant la navigation tel que défini dans les revendications. It goes without saying that the invention is not limited to the examples described and illustrated in this document. It covers any mechanism for modifying the position of the foils during navigation as defined in the claims.
