Abstract

The hull has a very fine immersed central bow (1) with a horizontal wing (3) which prevents the detachment and plunging movement of the bow in the water. The bow maintains an air inlet under a high bend part (2) of the hull, at the constant height above the water, to optimize the water inlet. Ladle shaped curvilinear parts (4) are applied along two front/rear and right/left axes to confine the air contents (6). The high bend part of the hull is reduced towards the rear of the boat to obtain the compression of the air.

Description

-1- 1. Descriptions Cette invention concerne, le déplacement sur l'eau, de bateaux ou de navires, (voiles ou moteurs). Cette invention bouleverse les standards actuels, par les principes d'une coque/carène innovatrice. This invention relates to the movement on the water of boats or vessels (sails or engines). This invention disrupts the current standards, by the principles of an innovative hull / hull.

Cette invention ce décline en deux parties, la partie de proue (1), qui à pour rôle de fendre l'eau, offrant ainsi un minimum de résistance, et la deuxième partie coque inversée (2) de prolonger le travail de la première, en utilisant un matelas d'air et d'eau, créant ainsi la sustentation. En règle générale, on trouve deux types de coque ou carène de bateaux. 1) les coques dit à déplacement d'eau. Ces coques avec une étrave en V tulipée, ou à bulbe 10 demandent beaucoup de puissance à l'avancement, (consommation élevée) elles déplacent énormément d'eau, et n'en tirent pas partie. 2) les coques dit de surface. Ces coques immergées, sortent de l'eau au démarrage, déjaugeage pour planer sur l'eau, à une allure assez soutenue. Cette solution, coque planante est très contraignante dans une mer formée, les vagues soulèvent, la partie avant du bateau déjà 15 délestée, et les placages violents, de la coque sur la surface de l'eau, sont très épuisants et inconfortables. Cette invention annule, tout ou partie, les inconvénients et effets négatifs, des deux exemples cités ci-dessus. Première partie : La proue centrale immergée (1), très fine, elle permet de fendre l'eau, offrant ainsi 20 une résistance à l'avancement très faible, aussi ; elle est mouillée très en avant, pour anticiper le creux des vagues ; longue pour obtenir la flottabilité nécessaire ; haute sur l'eau pour défendre l'assaut des vagues et son enfouissement. Sur la partie basse immergée, elle reçoit une aile horizontale (3). Le rôle de celle-ci est d'annuler les mouvements de plongée et de décollement dans l'eau. Le principe d'immersion, de l'aile horizontale nous permet d'avoir le contrôle des amplitudes ; 25 l'aile horizontale stabilise et corrige l'assiette de la proue. Nous transformons la flottabilité de la proue, et l'efficacité de l'aile horizontale immergée en pivot d'appui principal pour le bateau. Deuxième partie : coque inversée (2) type ou forme de cuillère . Faite l'essai avec une cuillère à soupe ! La tenant par le manche, en laissant la partie cuillère vers le bas. Maintenant, placez-la 30 sous un robinet d'eau. Vous constaterez, que l'eau qui ruisselle sur la partie extérieure, n'est pas guidée, elle s'éparpille de chaque cotés et procure un frein à l'écoulement, comme les coques à déplacement d'eau, citées ci-dessus. Par contre, faite couler l'eau dans la partie intérieure, vous constaterez immédiatement, que le débit d'eau est parfaitement guidé, il n'y a pas d'éclaboussures, et qu'une pression positive, s'exerce sur la cuillère. Il y à donc concentration des forces, la coque 35 inversée est inventée. -2-Cette coque/carène exploite et emprisonne la puissance de l'air et de l'eau sous elle-même, les formes et parties au contact de l'eau ont une courbure (4) spécialement étudiées et son compartimentées. Les parties curvilignes (4), s'applique dans les deux axes, avant / arrière, droite et gauche type cuillère . L'écoulement, devient parfaitement conditionné et optimisé, la courbure (4) haute, sur l'eau au niveau de la proue, diminue au fur et à mesure pour obtenir la compression souhaitée (5), il n'y a pas de déperdition, la pression de l'air et de l'eau, procure une force de soulèvement naturelle, il y à concentration des forces, chaque volume d'eau déplacé contribue à la compression. This invention is divided into two parts, the bow part (1), whose role is to split the water, thus offering a minimum of resistance, and the second inverted shell part (2) to extend the work of the first, using a mattress of air and water, creating the lift. Generally, there are two types of hull or hull of boats. 1) the hulls says to water displacement. These hulls with a tulip-shaped V-bow or bulb 10 require a lot of power to the progress, (high consumption) they move a lot of water, and do not take advantage of it. 2) hulls called surface. These submerged hulls, out of the water at startup, planing to hover over the water at a fairly steady pace. This solution, planing hull is very restrictive in a formed sea, the waves raise, the front part of the already unloaded boat, and the violent veneers, of the hull on the surface of the water, are very exhausting and uncomfortable. This invention cancels all or part of the disadvantages and negative effects of the two examples mentioned above. First part: The immersed central bow (1), very thin, it allows splitting the water, thus offering a very low resistance to advance, too; it is wet very far forward, to anticipate the hollow of the waves; long to obtain the necessary buoyancy; high on the water to defend the onslaught of waves and its burial. On the low submerged part, it receives a horizontal wing (3). The role of this one is to cancel the movements of diving and detachment in the water. The principle of immersion, the horizontal wing allows us to control the amplitudes; The horizontal wing stabilizes and corrects the attitude of the bow. We transform the buoyancy of the bow, and the efficiency of the submerged horizontal wing into the main support pivot for the boat. Second part: inverted shell (2) type or spoon shape. Try it out with a tablespoon! Holding it by the handle, leaving the spoon portion down. Now, place it under a water tap. You will notice, that the water which flows on the outside part, is not guided, it is scattered on each side and provides a brake to the flow, like the shells with displacement of water, quoted above. On the other hand, run the water in the inner part, you will see immediately, that the flow of water is perfectly guided, there is no splashing, and that a positive pressure, is exerted on the spoon . There is therefore a concentration of forces, the inverted hull is invented. -2-This hull / hull exploits and traps the power of the air and the water itself, the shapes and parts in contact with water have a curvature (4) especially studied and compartmentalized. The curvilinear parts (4), applies in both axes, front / back, right and left spoon type. The flow becomes perfectly conditioned and optimized, the curvature (4) high, on the water at the bow, decreases gradually to obtain the desired compression (5), there is no loss , the pressure of air and water, provides a natural lifting force, there is concentration of forces, each volume of water displaced contributes to compression.

Nous transformons la puissance des vagues en force sustentatrice, qui stabilise et porte le bateau sur un matelas d'air et d'eau. Le principe d'admission d'air (6), en grand volume, aide par sa compression à la sustentation, mais surtout, oxygène l'eau et accroit fortement son pouvoir de glisse. Les avantages accrus : Diminution importante, de la résistance à l'avancement, donc économies, moteur moins puissant, consommation diminuée, et par conséquence, moins de bruits. Par une défense de proue très fine, aidé de l'aile horizontale immergée, le bateau rentre dans la vague, sans chocs avec fluidité. Ceci lui donne, une grande capacité à absorber une mer tourmentée, et lui octroie un grand confort de navigation et de stabilité. We turn the power of waves into buoyancy, which stabilizes and carries the boat on a mattress of air and water. The principle of admission of air (6), in large volume, helps by its compression to the lift, but most importantly, oxygenates the water and greatly increases its gliding power. Increased benefits: Significant reduction in the resistance to progress, so savings, less powerful engine, decreased consumption, and consequently less noise. By a very fine bow defense, helped by the submerged horizontal wing, the boat enters the wave, without shocks with fluidity. This gives it a great capacity to absorb a troubled sea, and gives it a great comfort of navigation and stability.

Diminution importante des vagues, après le passage du bateau et de la traînée derrière la coque, donc ! Diminution importante, de la signature des moteurs et respect des berges. Au mouillage, les flottabilités bâbord et tribord sont augmentées grâce à la coque inversée, elles stabilisent parfaitement le bateau. Quant à la proue, elle joue toujours son rôle de défense, et protège des vagues. Aussi, le bateau peut se poser sur le sable sans risque de basculer. Significant decrease of the waves, after the passage of the boat and the trail behind the hull, therefore! Significant decrease, the signing of engines and respect the banks. At anchor, the port and starboard buoyancy are increased thanks to the inverted hull, they perfectly stabilize the boat. As for the bow, it still plays its role of defense, and protects waves. Also, the boat can land on the sand without risk of tipping.

Une esthétique complètement nouvelle. La répartition des appuis (par flottabilité et sustentation) est de : 50% sur le 1/3 avant, et 50% sur le 1/3 arrière. La partie centrale, à très peu d'appui, elle prolonge l'écoulement de la proue est régule les entrées d'air et d'eau de la coque inversée, cette innovation neutralise les effets de bascule avant / arrière, la stabilité est parfaite il n'y à plus de tangage. A completely new aesthetic. The distribution of the supports (by buoyancy and lift) is: 50% on the 1/3 before, and 50% on the 1/3 back. The central part, with very little support, it prolongs the flow of the bow is regulates the air and water inlets of the inverted hull, this innovation neutralizes the effects of rocking forward / backward, the stability is perfect there is no more pitching.

Cette invention concerne avant tout le secteur nautique, de plaisance et professionnel, secours interventions rapides etc. Elle peut également intéresser l'aviation, mais uniquement pour les coques d'hydravion. -3- La figure 1 est une vue arrière de la coque selon l'invention. La figure 2 est une vue de face de la proue selon l'invention. La figure 3 est une vue de profil de la coque selon l'invention.5 This invention relates above all to the nautical sector, recreational and professional, emergency interventions etc. It may also interest aviation, but only for seaplane hulls.
