  • there Fig. 2 also shows a perspective view of the boat according to the invention without the kite.

EXPOSE DETAILLE DE MODES DE REALISATIONDETAILED DESCRIPTION OF EMBODIMENTS

La Fig. 1 et la Fig. 2 montrent un bateau 100 qui comporte une coque 102 avec un pont 104 sur lequel est montée une plateforme 106.There Fig. 1 and the Fig. 2 show a boat 100 which comprises a hull 102 with a deck 104 on which a platform 106 is mounted.

La plateforme 106 est montée pivotante sur le pont 104 autour d'un axe Z perpendiculaire au pont 104, c'est-à-dire vertical lorsque le bateau 100 est immobile. La plateforme 106 est ici disposée à l'avant de la coque 102 mais pourrait se situer plus en arrière.The platform 106 is pivotally mounted on the deck 104 around an axis Z perpendicular to the deck 104, that is to say vertical when the boat 100 is stationary. The platform 106 is here arranged at the front of the hull 102 but could be located further back.

Le bateau 100 est équipé d'un cerf-volant 110 qui est ici un cerf-volant à boudins mais qui pourrait prendre une autre forme comme par exemple un cerf-volant à caissons.The boat 100 is equipped with a kite 110 which here is a tube kite but which could take another form such as for example a box kite.

Le cerf-volant 110 comprend classiquement une aile 112 et des brides 114 où l'une des extrémités de chaque bride 114 est fixée à l'aile 112 et où l'autre extrémité de chaque bride 114 est fixée à une extrémité d'un câble 116, ici par l'intermédiaire d'un dispositif de contrôle et commande 118, également appelé « pod ».The kite 110 conventionally comprises a wing 112 and flanges 114 where one end of each flange 114 is fixed to the wing 112 and where the other end of each flange 114 is fixed to one end of a cable 116, here via a control and command device 118, also called “pod”.

Le bateau 100 comporte également un système de déploiement 150 où l'autre extrémité du câble 116 est fixée au système de déploiement 150 et qui permet, d'une part, d'allonger le câble 116 pour permettre l'envol du cerf-volant 110, et, d'autre part, de raccourcir le câble 116 pour ramener le cerf-volant 110.The boat 100 also includes a deployment system 150 where the other end of the cable 116 is fixed to the deployment system 150 and which makes it possible, on the one hand, to extend the cable 116 to allow the kite 110 to take off. , and, on the other hand, to shorten the cable 116 to bring back the kite 110.

Le système de déploiement 150 est fixé à la plateforme 106.The deployment system 150 is attached to the platform 106.

Dans le mode de réalisation de l'invention présenté ici, le système de déploiement 150 comporte un tambour motorisé 120 et une poulie 122.In the embodiment of the invention presented here, the deployment system 150 comprises a motorized drum 120 and a pulley 122.

Le tambour 120 est fixé à la plateforme 106 et autour du tambour 120 est enroulé le câble 116. Le tambour 120 est équipé d'un moteur qui permet de faire tourner le tambour 120 autour de son axe pour enrouler ou dérouler le câble 116 selon le sens de rotation du tambour 120. Dans le mode de réalisation de l'invention présenté ici, l'axe du tambour 120 est parallèle au pont 104, c'est-à-dire horizontal.The drum 120 is fixed to the platform 106 and the cable 116 is wound around the drum 120. The drum 120 is equipped with a motor which makes it possible to rotate the drum 120 around its axis to wind or unwind the cable 116 according to the direction of rotation of the drum 120. In the embodiment of the invention presented here, the axis of the drum 120 is parallel to the bridge 104, that is to say horizontal.

Pour assurer le guidage et le changement de direction du câble 116 entre le tambour 120 et le dispositif de contrôle et commande 118, et plus généralement les brides 114, le système de déploiement 150 comporte la poulie 122 qui est montée articulée sur la plateforme 106 et par laquelle passe la partie du câble 116 qui est entre le tambour 120 et le dispositif de contrôle et commande 118, et plus généralement les brides 114.To ensure the guidance and change of direction of the cable 116 between the drum 120 and the control and command device 118, and more generally the flanges 114, the deployment system 150 includes the pulley 122 which is mounted articulated on the platform 106 and through which passes the part of the cable 116 which is between the drum 120 and the control device 118, and more generally the flanges 114.

Le bateau 100 comporte également un mât 180 qui est fixé à la plateforme 106 et qui présente une pluralité de bras 182 qui s'étendent globalement parallèlement au pont 104, c'est-à-dire horizontalement.The boat 100 also includes a mast 180 which is fixed to the platform 106 and which has a plurality of arms 182 which extend generally parallel to the deck 104, that is to say horizontally.

Dans le mode de réalisation de l'invention présenté ici, les bras 182 s'étendent ici vers l'avant par rapport au mât 180 dans la direction du vent relatif au bateau 100.In the embodiment of the invention presented here, the arms 182 extend here forward relative to the mast 180 in the direction of the wind relative to the boat 100.

Les bras 182 sont disposés de manière à se positionner sous l'aile 112 et à supporter l'aile 112 lorsque le cerf-volant 110 est ramené, c'est-à-dire lorsque le câble 116 est raccourci.The arms 182 are arranged so as to be positioned under the wing 112 and to support the wing 112 when the kite 110 is brought back, that is to say when the cable 116 is shortened.

En outre, l'indépendance des câbles 116 vis-à-vis des bras 182 et du mât 180 donne une grande souplesse de positionnement pour en particulier gérer l'appontage du kite.In addition, the independence of the cables 116 with respect to the arms 182 and the mast 180 gives great flexibility in positioning, in particular to manage the landing of the kite.

Ainsi, lorsque le cerf-volant 110 n'est pas utilisé, l'aile 112 repose sur les bras 182, ce qui empêche que les brides 114 s'emmêlent et ce qui permet un déploiement plus rapide du cerf-volant 110 en cas de besoin, puisqu'il suffit de rallonger le câble 116 pour que le cerf-volant 110 s'envole.Thus, when the kite 110 is not used, the wing 112 rests on the arms 182, which prevents the flanges 114 from getting tangled and which allows faster deployment of the kite 110 in the event of necessary, since it is enough to extend the cable 116 for the kite 110 to fly.

Un procédé de mise en oeuvre du cerf-volant consiste, à partir d'une position où l'aile 112 repose sur les bras 182, en :

  • une étape d'allongement au cours de laquelle le câble 116 est allongé par le système de déploiement 150,
  • une étape d'envol au cours de laquelle l'aile 112 se décolle des bras 182 et s'envole,
  • une étape de vol au cours de laquelle l'aile 112 vole,
  • une étape de raccourcissement au cours de laquelle le câble 116 est raccourci par le système de déploiement 150, et
  • une étape d'atterrissage au cours de laquelle l'aile 112 se positionne sur les bras 182.
A method of operating the kite consists, from a position where the wing 112 rests on the arms 182, in:
  • an elongation step during which the cable 116 is elongated by the deployment system 150,
  • a take-off stage during which the wing 112 detaches from the arms 182 and flies away,
  • a flight stage during which the wing 112 flies,
  • a shortening step during which the cable 116 is shortened by the deployment system 150, and
  • a landing stage during which the wing 112 positions itself on the arms 182.

L'étape d'allongement se poursuit également au cours de l'étape d'envol et éventuellement au cours de l'étape de vol.The elongation stage also continues during the takeoff stage and eventually during the flight stage.

L'étape de raccourcissement se poursuit au cours de l'étape d'atterrissage.The shortening stage continues during the landing stage.

Dans le mode de réalisation de l'invention présenté ici, il y a deux bras 182, mais il peut y en avoir plus selon la taille de l'aile 112.In the embodiment of the invention presented here, there are two arms 182, but there may be more depending on the size of the wing 112.

De la même manière, dans le mode de réalisation de l'invention présenté ici, le mât 180 est centré par rapport à la poulie 122 et les bras 182 sont disposés symétriquement de part et d'autre du mât 180, mais il est possible de prévoir que le mât 180 soit décentré par rapport à la poulie 122 et que les bras 182 ne soient pas disposés symétriquement par rapport au mât 180. Les bras 182 sont disposés au-dessus de la poulie 122.In the same way, in the embodiment of the invention presented here, the mast 180 is centered relative to the pulley 122 and the arms 182 are arranged symmetrically on either side of the mast 180, but it is possible to provide that the mast 180 is off-center relative to the pulley 122 and that the arms 182 are not arranged symmetrically in relation to the mast 180. The arms 182 are arranged above the pulley 122.

Pour faciliter l'éloignement de l'aile 112 et le rapprochement de l'aile 112 par rapport aux bras 182 sans que les brides 114 soient gênées par les bras 182, ceux-ci sont escamotables.To facilitate moving the wing 112 away and bringing the wing 112 closer to the arms 182 without the flanges 114 being hindered by the arms 182, they are retractable.

Lorsque l'aile 112 repose sur les bras 182, le décollage de l'aile 112 consiste en un court relâchement du câble 116 pour décoller l'aile 112 des bras 182, puis un escamotage des bras 182, et enfin un relâchement complet du câble 116 pour permettre l'envol de l'aile 112.When the wing 112 rests on the arms 182, the takeoff of the wing 112 consists of a short release of the cable 116 to take off the wing 112 from the arms 182, then a retraction of the arms 182, and finally a complete release of the cable 116 to allow the wing 112 to take off.

Lorsque l'aile 112 est en vol, l'atterrissage de l'aile 112 consiste en un raccourcissement du câble 116 jusqu'à une position légèrement au-dessus des bras 182, puis une remise en place des bras 182 escamotés, et enfin un raccourcissement complet du câble 116 pour mettre en appui l'aile 112 sur les bras 182.When the wing 112 is in flight, the landing of the wing 112 consists of a shortening of the cable 116 to a position slightly above the arms 182, then a replacement of the retracted arms 182, and finally a complete shortening of the cable 116 to support the wing 112 on the arms 182.

L'escamotage des bras 152 est réalisé par tous moyens appropriés qu'ils soient manuels ou motorisés. Il peut s'agir par exemple d'un moteur qui, sur commande, fait tourner les bras 152 vers le bas ou vers l'intérieur.The arms 152 are retracted by any appropriate means, whether manual or motorized. It may for example be a motor which, on command, turns the arms 152 downwards or inwards.

Le procédé de mise en oeuvre comporte alors préalablement à l'étape d'allongement :

  • une étape de relâchement au cours de laquelle le câble 116 est légèrement allongé par le système de déploiement 150 pour décoller l'aile 112 des bras 182,
  • une étape d'escamotage au cours de laquelle les bras 182 sont escamotés automatiquement ou manuellement,
et entre l'étape de raccourcissement et l'étape d'atterrissage, une étape de remise en place au cours de laquelle les bras 182 sont remis en place lorsque l'aile 112 est dans une position légèrement au-dessus des bras 182.The implementation process then comprises, prior to the elongation step:
  • a release step during which the cable 116 is slightly extended by the deployment system 150 to detach the wing 112 from the arms 182,
  • a retraction step during which the arms 182 are retracted automatically or manually,
and between the shortening step and the landing step, a repositioning step during which the arms 182 are put back in place when the wing 112 is in a position slightly above the arms 182.
