Description
Hvdront6re a coussin d ' air
La présente invention concerne l'application conjointe,à un engin destiné à assurer, sur rivières, canaux lacs ou eaux calmes, le transport rapide de passagers,véhicules ou matériaux, d'un système de sustentation ou déjaugeage,connu sous le
nom de coussin d'air et d'un système de propulsion connu et développé sous le nom d'hydroptére.Air cushion head
The present invention relates to the joint application, to a machine intended to ensure, on rivers, canals or calm waters, the rapid transport of passengers, vehicles or materials, of a lift or planing system, known as
name of air cushion and of a propulsion system known and developed under the name of hydrofoil.
D'une facon générale,on connait les inconvénients q(te présentent les bateaux légers ou moyens assurant le transport des personnes ou des véhicules: lenteur des déplacements et des mapeuvres d'accostage ou d'évitement, importance des masses inertes rapportées aux charges utiles,présence d'un important sillage qui peut constituer une sérieuse gêne. In general, we know the drawbacks q (present to you the light or medium boats ensuring the transport of people or vehicles: slowness of the movements and of the docking or avoidance works, importance of the inert masses compared to the payloads , presence of an important wake which can constitute a serious embarrassment.
L'invention du coussin d'air assurant le déjaugeage du navire,a permis,en annulant presque la traînée dans l'eau, d'accrottre sensiblement les vitesses.En revanche,la propulsion étant, le plus souvent,assurée par des moteurs et hélices d'axZion,il en résulte d'importantes nuisances. The invention of the air cushion ensuring the planing of the ship, made it possible, by almost canceling the drag in the water, to increase the speeds appreciably. On the other hand, the propulsion being, most often, ensured by engines and propellers of axZion, this results in significant nuisance.
L'invention de l'hydroptère,basée sur la propulsion par des groupes moteur électrique-hélice immergés,a apporté, dans le domaine de la maniabilité des engins de surface,un progrès considérable.ais en demandant à ces mêmes groupes d'assurer aussi,grace à des volets, le déjaugeage,on a créé des difficultés quasi-insurmontables. The invention of the hydrofoil, based on propulsion by submerged electric motor-propeller groups, has brought considerable progress in the field of the maneuverability of surface craft, but by asking these same groups to also provide , thanks to shutters, planing, we created almost insurmountable difficulties.
L'idée inventive,à la base du présent brevet, consiste à distinguer les deux fonctions:déjaugeage et propulsion,puis à associer les deux principes:coussin d'air et propulsion par moteur-hélice immergé.The inventive idea which forms the basis of this patent consists in distinguishing the two functions: planing and propulsion, then in combining the two principles: air cushion and propulsion by submerged propeller-propeller.
Le système du coussin d'air permet d'obtenir le déjaugeage indépendamment de la vitesse, dans d'excellentes conditions techniques et économiques. The air cushion system allows planing to be obtained regardless of speed, in excellent technical and economic conditions.
La propulsion, par 3.4 ou plusieurs groupes indépendants, associant moteur électrique immergé et hélice est une solution souple et économique.Ces moteurs sont alimentés en courant continu ou alternatif,en moyenne tension, par un groupe Diesel de puissance adaptée.Une batterie d'accumulateurs peut assurer les faibles déplacements et pallier les pannes de courte durée.Les moteurs sont suspendus sous la coque,grace à des jambe-supports de telle sorte que ces moteur-hélices restent immergés lorsque le bateau est déjaugé.Placés à l'extrémité de ces futs tronconiques,ces moteurs peuvent pivoter instantanément dans toutes les directions(360')afin de réaliser dans un temps très court et avec le maximum d'éfficacité,toutes les maleuvres d'approche,d'évitement,de démarrage et ce à pleine puissance. Propulsion, by 3.4 or more independent groups, associating submerged electric motor and propeller is a flexible and economical solution. These motors are supplied with direct or alternating current, at medium voltage, by a Diesel group of suitable power. can ensure small displacements and compensate for short-term breakdowns. The motors are suspended under the hull, thanks to leg-supports so that these motor-propellers remain submerged when the boat is planed. Placed at the end of these tapered barrels, these motors can pivot instantly in all directions (360 ') in order to achieve in a very short time and with maximum efficiency, all the approach, avoidance, start-up malevolence and this at full power .
Un cablage électrique remplace les arbres des hélices classiques. L'étanchéité ne pose aucun problème, remplacée par
l'isolation électrique classique.Electrical wiring replaces the shafts of conventional propellers. Sealing is no problem, replaced by
classic electrical insulation.
Le groupe Diesel est placé sous le pont,près du poste de pilotage qui devient un poste électrique controlé par un automate.Il n'y a pas de gouvernail. The Diesel group is placed under the bridge, near the cockpit which becomes an electrical station controlled by an automaton. There is no rudder.
La vitesse obtenue peut atteindre 100Km/h et n'est limitée
que par l'environnement et la sécurité.The speed obtained can reach 100Km / h and is not limited
only through the environment and security.
Un système de jupes souples et de cloisons fixes assure l'étanchéité du volume d'air qui sous une légère pression, assure le déjaugeage et le maintien au-dessus de l'eau de l'ensemble coque-cloisons-jupes.Des ventilateurs,non bruyants,å
vitesse variable assurent cette légère surpression qui est contrôlée électroniquement afin d'établir dans le volume de sustentation l'exacte pression nécessaire.Ce volume est découpé en quatre sous-volumes(bâbord,tribord,avant,arrière) de telle sorte que l'on puisse compenser les différences de charges et assurer l'horizontalité du plancher.A system of flexible skirts and fixed partitions ensures airtightness of the air volume which, under slight pressure, ensures the planing and maintenance above water of the shell-partitions-skirts assembly. not noisy, å
Variable speed ensures this slight overpressure which is electronically controlled in order to establish the exact pressure required in the lift volume. This volume is divided into four sub-volumes (port, starboard, forward, aft) so that can compensate for differences in loads and ensure the horizontality of the floor.
La barge est à fond piat,les superstructures sont de faible hauteur,il n'y a pas de mats. Elle est conçue pour le transport de passagers, de véhicules ou mixte. The barge is completely piat, the superstructures are low, there are no masts. It is designed for the transport of passengers, vehicles or mixed.
L'embarquement et le débarquement des passagers se fait latéralement,des deux cotés.L'embarquement des véhicules peut se faire frontalement,par l'avant ou l'arrière.En fait ce type d'engin n'a pas,à proprement parléT,ni avant ni arrière, il est parfaitement symétrique. Boarding and disembarking of passengers is done laterally, on both sides. Vehicles can be boarded frontally, from the front or rear. In fact, this type of vehicle does not, strictly speaking , neither front nor rear, it is perfectly symmetrical.
Selon le tirant d'air disponible,la barge peut avoir un ou deux niveaux,elle peut aussi être conçue pour le transport de camions et remorques.Sous certaines conditions elle peut être conçue pour le transport de vrac léger. Depending on the available draft, the barge can have one or two levels, it can also be designed for the transport of trucks and trailers. Under certain conditions it can be designed for the transport of light bulk.
Destiné à naviguer sur rivières,canaux ou lacs,l'hydroptère peut avoir un fond plat, sans quille ni gouvernail et ne nécessite pas de jupes renforcées pour résister aux vagues.Les ruptures d'étanchéité du volume de sustentation ne sont pas à craindre. Intended to navigate on rivers, canals or lakes, the hydrofoil can have a flat bottom, without keel or rudder and does not require reinforced skirts to resist waves. The leakages of the lift volume are not to be feared.
L'engin est silencieux, car les ventilateurs de surpression sont de faible puissance et convenablement choisis (ventilateurs centrifuges).Du fait du déjaugeage les remous du sillage et l'érosion des berges qui en résulte n'existent pas. La vitesse de l'hydroptère ne saurait de ce fait être limitée
ni mbme pour des raisons de sécurité, compte tenu de sa parfaite maniabilité.The machine is silent, because the overpressure fans are of low power and suitably chosen (centrifugal fans). Due to the planing the eddies of the wake and the erosion of the banks which results from it do not exist. The speed of the hydrofoil can therefore not be limited
nor even for safety reasons, given its perfect maneuverability.
Le faible encombrement des superstructures facilite le passage sous les ponts,même en période de crues. The small size of the superstructures facilitates passage under bridges, even during floods.
Le rendement global de ce moyen de transport est particulièrement bon, car le rapport masse transportée sur masse inerte est élevé et la puissance absorbée réduite au minimum par la suppression de la tramée dans l'eau. The overall efficiency of this means of transport is particularly good, because the ratio of mass transported to inert mass is high and the power absorbed reduced to a minimum by eliminating the screen in the water.
L'hydroptère à coussin d'air est parfaitement adapté aux transports urbains,en complément des réseaux traditionnels,dans toutes les agglomérations importantes arrosées par un fleuve ou une rivière,au bord d'une lagune ou d'une mer calme.Il convient aussi pour tous les déplacements utilitaires ou touristiques sur tous les fleuves ou plans d'eau calme. The air cushion hydrofoil is perfectly suited to urban transport, in addition to traditional networks, in all major cities watered by a river or a river, on the edge of a lagoon or calm sea. for all utility or tourist trips on all rivers or calm water bodies.
L'investissement unitaire est relativement faible et les aménagements d'accès simples. The unit investment is relatively low and the access facilities simple.
La conduite de chaque engin peut être confiée à un seul pilote qualifié pour les trajets urbains,si le bateau a été convenablement équipé de radars,projecteurs,systèmes d'amarrage automatiques, liaisons radio, dépannage organisé,ancrage automatique, sécurité corps mort, etc. The driving of each machine can be entrusted to a single pilot qualified for urban journeys, if the boat has been suitably equipped with radars, searchlights, automatic mooring systems, radio links, organized breakdown service, automatic anchoring, dead body security, etc. .
