Description

Propulseur individuel sous-marin. Individual submarine thruster.
La présente invention concerne un propulseur électrique destiné à la plongée sous- marine. Les systèmes de propulsion sous-marins traditionnels sont conçus comme des torpilles et le flux principal résultant de la rotation de l'hélice se trouve éjecté suivant l'axe de symétrie de l'appareil.The present invention relates to an electric thruster intended for scuba diving. Traditional submarine propulsion systems are designed like torpedoes and the main flow resulting from the rotation of the propeller is ejected along the axis of symmetry of the aircraft.
Le plongeur doit donc se déporter par rapport à cet axe et le maître couple dans la direction du déplacement se trouve augmenté.The plunger must therefore move away from this axis and the master torque in the direction of movement is increased.
Il en résulte un effort de tangage, une fatigue du pilote et une perte d'énergie. D'autre part la manœuvrabilité est fortement affectée par la position relative du plongeur par rapport au propulseur. Des vitesses importantes ne peuvent être atteintes par ce type d'appareil.This results in a pitching effort, pilot fatigue and loss of energy. On the other hand, the maneuverability is strongly affected by the relative position of the plunger relative to the propellant. Significant speeds cannot be achieved with this type of device.
La figure 1 montre un tel propulseur traditionnel, le plongeur doit être décalé suivant l'axe OZ pour se placer au dessus des turbulences générées par l'hélice.Figure 1 shows such a traditional propellant, the plunger must be offset along the axis OZ to be placed above the turbulence generated by the propeller.
La présente invention permet d'améliorer les performances du propulseur et de faciliter le pilotage. A cette fin le propulseur est constitué par une hyperforme symbolique symétrique par rapport au plan de déplacement OXY, figure 2, du plongeur. Cette forme apporte l'équivalent de deux palettes natatoires profilées dans l'axe OX de déplacementThe present invention improves the performance of the propellant and facilitates piloting. To this end, the propellant is constituted by a symbolic hyperform symmetrical with respect to the plane of movement OXY, FIG. 2, of the plunger. This shape provides the equivalent of two profiled swimming paddles in the OX axis of movement
La figure 2 montre le principe de base d'un tel système. Le plongeur tient l'appareil à bout de bras dans l'axe du déplacement, l'eau est aspirée par une ouverture 1 située à l'avant. Le flux entrant est ensuite divisé dans deux transferts symétriques et refoulé de part et d'autre du plongeur. Les deux flux secondaires 2 sont partiellement divergents pour améliorer l'hydrodynamique et la propulsion se fait par réaction.Figure 2 shows the basic principle of such a system. The diver holds the device at arm's length in the axis of movement, the water is sucked through an opening 1 located at the front. The incoming flow is then divided into two symmetrical transfers and discharged on either side of the diver. The two secondary flows 2 are partially divergent to improve the hydrodynamics and the propulsion is by reaction.
La forme et la tenue d'un tel propulseur, selon l'invention, permettent au plongeur de contrôler le roulis et le tangage.The shape and the behavior of such a thruster, according to the invention, allow the diver to control the roll and the pitch.
Le mouvement de lacet est facilité par la forme aplatie du corps dans le plan OXY. Pour le rendre plus directif un aileron 6 peut être monté comme indiqué sur la figure 3 qui définit enThe yaw movement is facilitated by the flattened shape of the body in the OXY plane. To make it more directive a fin 6 can be mounted as shown in Figure 3 which defines
3 vues la forme d'ensemble résultant d'une étude initiale purement esthétique ayant fait l'objet de fαnctionnaϋsations successives suivant les résultats techniques recherchés.3 views the overall shape resulting from an initial purely aesthetic study that has been the subject of successive fαnctionnaϋsations according to the technical results sought.
Ainsi le profil d'aile choisi pour le corps est neutre, détail 5 figure 3, car en plongée le poids est compensé par la poussée hydrostatique et il ne doit résulter aucune portance dynamique lors des déplacements.Thus the wing profile chosen for the body is neutral, detail 5 in Figure 3, because when diving the weight is compensated by the hydrostatic thrust and there should be no dynamic lift during movement.
Deux phares 8 et un contrôle de vitesses 7 peuvent être intégrés à l'engin.Two headlights 8 and a speed control 7 can be integrated into the vehicle.
La figure 4 montre un plongeur équipé d'un tel système. Dans ce cas précis les accumulateurs étanches 3 sont placés à l'extérieur du propulseur, à la ceinture. Us peuvent aussi être fixés dans le dos du plongeur ou sur les bouteilles de plongée. Ainsi structuré le propulseur est moins volumineux, plus léger et plus performant. De plus, les batteries placées à l'extérieur permettent de remplacer les lests habituellement utilisés pour équilibrer le plongeur.Figure 4 shows a diver equipped with such a system. In this specific case, the sealed accumulators 3 are placed outside the propellant, at the waist. They can also be fixed on the back of the diver or on diving tanks. Thus structured, the propellant is less bulky, lighter and more efficient. In addition, the batteries placed outside can replace the weights usually used to balance the diver.
FEUILLE DE REMPLACEMENT D'où un gain de poids supplémentaire par rapport à un propulseur traditionnel, un câble - 4 permet l'alimentation en énergie électrique du moteur intégré à l'appareil.REPLACEMENT SHEET Hence an additional weight saving compared to a traditional propellant, a cable - 4 allows the supply of electrical energy to the motor integrated in the device.
Dans le cas où une grande autonomie est requise, le poids correspondant aux batteries peut être compensé par des volumes de mousse de densité inférieure à un, cette compensation peut aussi être effectuée par l'intermédiaire d'un gilet de plongée gonflable.In the case where a long autonomy is required, the weight corresponding to the batteries can be compensated by volumes of foam of density less than one, this compensation can also be carried out by means of an inflatable diving vest.
Des batteries polymères de densité sensiblement égale à 2 peuvent aussi être utilisées et nécessitent peu .de compensation hydrostatique.. -Polymer batteries with a density substantially equal to 2 can also be used and require little hydrostatic compensation. -
La figure 5 montre l'équilibre d'un tel système de propulsion réalisé suivant l'invention.FIG. 5 shows the balance of such a propulsion system produced according to the invention.
Le corps 9" ' réalisé en matériaux de densité inférieure à un, produit une poussée hydrostatique dirigée vers le haut en G. Le poids total du propulseur comprenant le corps et les accessoires intérieurs tels le moteur 14 et le système de pilotage 11 doit correspondre à G pour que le propulseur soit en équilibre quelle que soit sa position.The body 9 "' made of materials with a density less than one, produces a hydrostatic thrust directed upwards at G. The total weight of the propellant comprising the body and the interior accessories such as the engine 14 and the control system 11 must correspond to G so that the thruster is in balance whatever its position.
Les poignées 10 intégrées directement au corps et les efforts de réaction R doivent être sensiblement alignés dans une zone Z la plus réduite possible selon OX. Cette vue éclatée d'un propulseur conçu selon l'invention montre aussi le corps 9* constitué de deux demi-coques fabricationj'assemblage et la maintenance sont ainsi considérablement simplifiés, l'investissement en moules est diminué.The handles 10 integrated directly into the body and the reaction forces R must be substantially aligned in a zone Z as small as possible according to OX. This exploded view of a propellant designed according to the invention also shows the body 9 * consisting of two half-shells manufacturing, assembly and maintenance are thus considerably simplified, investment in molds is reduced.
L'assemblage de ces deux demi-coques suivant le plan OXY permet d'obtenir la forme extérieure avec ses qualités,hydrodynamique et esthétique. D'autre part des formes intérieures résultent aussi de cet assemblage et permettait d'obtenir le principe de base de l'invention concernant la séparation en deux flux symétriques par deux transferts.The assembly of these two half-shells according to the OXY plan makes it possible to obtain the external shape with its qualities, hydrodynamic and aesthetic. On the other hand, interior shapes also result from this assembly and made it possible to obtain the basic principle of the invention concerning the separation into two symmetrical flows by two transfers.
Ainsi les formes intérieures sont harmonisées avec les formes extérieures pour réduire au maximum le volume immergé.Thus the interior shapes are harmonized with the exterior shapes to minimize the submerged volume.
Le moteur 14 figure 6 est placé de façon à correspondre avec le centre de poussée hydrostatique G car il est l'élément le plus pesant et un décalage nécessiterait un équilibrage par des masses additionnelles.The motor 14 in FIG. 6 is placed so as to correspond with the hydrostatic thrust center G because it is the heaviest element and an offset would require balancing by additional masses.
Une chambre 15 est aménagée autour du moteur pour son refroidissement, la circulation de l'eau est assurée par un conduit calibré 21 dont l'admission se situe en aval de la turbine et l'évacuation vers l'arrière 16 Ce conduit est calibré suivant la puissance choisie pour le moteur et la quantité correspondante de chaleur à évacuer.A chamber 15 is arranged around the engine for its cooling, the circulation of water is ensured by a calibrated conduit 21 whose intake is located downstream of the turbine and the discharge towards the rear 16 This conduit is calibrated according to the power chosen for the engine and the corresponding amount of heat to be removed.
Un emplacement pour l'électronique de commande est prévu à l'arrière du moteur, la figure 6 montre un tel élément de commande 11 comportant deux bras munis d'interrupteurs étanches 12 aboutissant au niveau des poignées de maintien. Cet élément de commande est obtenu par surmoulage des composants sur une carte électronique et placé dans un logement directement moulé sur le corps.A location for the control electronics is provided at the rear of the engine, FIG. 6 shows such a control element 11 comprising two arms provided with sealed switches 12 leading to the level of the grab handles.

Une zone d'impulsion primaire 25 résultant d'un profil asymétrique 26 du conduit permet d'amorcer un axe dynamique 22 vers la zone d'impulsion secondaire 24The initial flow generated by the high efficiency turbine is optimally divided. The dynamic aspect of the flow is described by the figure! .. Firstly the separation edge 28 operates a first division along the axis of geometric symmetry 27 of the transfer. A primary pulse zone 25 resulting from an asymmetrical profile 26 of the conduit makes it possible to initiate a dynamic axis 22 towards the secondary pulse zone 24
La forme du conduit est obtenue par le passage progressif de 26 à 23 selon l'axe de symétrie géométrique et il en résulte un écoulement selon l'axe dynamique ' avec le minimum de turbulences et une meilleure réaction hydrodynamique.The shape of the duct is obtained by the progressive passage from 26 to 23 along the axis of geometric symmetry and this results in a flow along the dynamic axis' with the minimum of turbulence and a better hydrodynamic reaction.
Des volets de contrôle 30 peuvent être installés en bout d'ailes suivant la figure β . Us permettent d'agir sur le roulis et le tangage en actionnant deux leviers 32 situés près des poignées et liés aux volets par deux axes ,29 perpendiculaires à la direction du déplacement.Control flaps 30 can be installed at the end of wings according to FIG. Β. They make it possible to act on the roll and the pitch by actuating two levers 32 located near the handles and linked to the flaps by two axes, 29 perpendicular to the direction of movement.
