Abstract
Ce procédé de conception et de fabrication concerne de nouveaux propulseurs qui ont des turbines intégrées dans les pales des hélices. La construction est faite en partant de deux lames qui en se vrillant vont former le conduit de la turbine intégrée dans la pale de l'hélice. Ce type de propulseur permet en associant l'intérêt d'une turbine à celui d'une hélice, d'obtenir à diamètre égale, des poussées axiales bien supérieures à celle obtenu avec les hélices seules.This design and manufacturing process involves new propellers that have turbines embedded in the propeller blades. The construction is made starting from two blades which, by twisting, will form the duct of the integrated turbine in the blade of the propeller. This type of thruster allows combining the interest of a turbine to that of a propeller, to obtain equal diameter, axial thrusts much greater than that obtained with the propellers alone.
Description
DESCRIPTION Ce procédé de conception et fabrication concerne des propulseurs qui sont des hybrides qui intègrent des turbines centrifuges dans les pales creuses des hélices.DESCRIPTION This design and manufacturing process concerns propellants that are hybrids that integrate centrifugal turbines into the hollow blades of the propellers.
Cela fait appel à des formes complexes jadis impossible à réaliser et seuls les outils modernes permettent maintenant de les concevoir et de les construire industriellement. Ce n'est qu'après de nombreuses années de recherche que nous avons pu réaliser les premiers prototypes. Il est démontré que l'augmentation des vitesses de rotation, possibles avec les nouveaux 10 moteurs électriques, ne permet plus aux propulseurs connus de répondre aux nouveaux problèmes de cavitation des liquides ou de détente des gaz qui sont maintenant imposés. A vitesse de rotation et diamètre équivalent, une plus grande poussée axiale est obtenue par les nouveaux produits obtenus grâce à ce nouveau procédé de conception et de fabrication de propulseurs. 15 Cela est du au fait que chacune des pales est construite avec au moins deux lames différentes (1, AA) (chaque lame pouvant être construite avec des morceaux de lames) qui partent ouvertes à l'avant près de l'axe (0) à la partie centrale de la roue, et forment progressivement le conduit interne d'une pale qui se vrillent en spirale dont les lames de l'intrados et l'extrados sont solidarisés sur l'un de leurs bords, mais dont les autres bords partent du centre en étant ouverts 20 gueule bée. Ces dernières lames se referment progressivement et se solidarisent lors de l'augmentation de diamètre et forment un conduit fermée convexe (2, BB) ou concave (3, BB). Ce conduit se termine aux plus grands diamètres de la roue, et sa sortie est dirigée vers l'arrière du propulseur (4,). 25 Il faut remarquer que la lame de l'intrados à l'avant près de l'axe (0), à la partie centrale de la roue, part avec retard vis à vis de la lame de l'extrados (C). De même les lames au départ sont ouvertes gueule bée, et sont décalées plus en retrait l'une de l'autre (1) et peuvent être concave ou convexe.This calls for complex shapes formerly impossible to achieve and only modern tools now allow to design and build them industrially. It was only after many years of research that we were able to make the first prototypes. It has been shown that the increase in rotational speeds, possible with the new electric motors, no longer allows the known thrusters to respond to the new liquid cavitation or gas expansion problems that are now imposed. With a rotation speed and equivalent diameter, a greater axial thrust is obtained by the new products obtained thanks to this new process of design and manufacture of thrusters. This is because each of the blades is constructed with at least two different blades (1, AA) (each blade can be constructed with pieces of blades) that leave open at the front near the axis (0). at the central part of the wheel, and progressively form the internal duct of a blade that twist spirally whose blades of the intrados and the extrados are secured on one of their edges, but whose other edges leave from the center by being open 20 mouth open. These latter blades are closed progressively and solidarize during the increase in diameter and form a convex closed duct (2, BB) or concave (3, BB). This duct ends at the largest diameters of the wheel, and its output is directed towards the rear of the thruster (4,). It should be noted that the blade of the intrados at the front near the axis (0), at the central part of the wheel, leaves late with respect to the blade of the extrados (C). Likewise, the blades at the beginning are open jawed, and are shifted further away from each other (1) and can be concave or convex.
Aussi lorsque les lames sont fermées, elles sont de préférence décalées et plus en retrait l'une de l'autre, (4) et de préférence les bords d'attaque et de fuite sont adoucis par des arrondis (G).Also when the blades are closed, they are preferably offset and further recessed from each other, (4) and preferably the leading and trailing edges are softened by rounding (G).
Les lames au centre lorsqu'elles sont ouvertes sont solidarisées avec au moins un élément solide commun permettant la liaison à l'intérieur avec d'autres éléments pour la rotation. Les parties des pales de l'hélice creuse, situées à son plus grand diamètre, sont souvent recourbées vers l'arrière de la roue, et inclinées pour orienter la sortie du conduit (F). Couramment les pales du propulseur sont solidarisées entre elles par au moins une bague 10 circulaire (E) qui les entoure de préférence aux plus grands diamètres de la roue. Pour permettre la fabrication industrielle des propulseurs les lames de l'extrados des pales du propulseur sont assemblées et solidarisées seules ensemble par des éléments circulaires, et les lames de l'intrados des pales du propulseur sont assemblées et solidarisées seules ensemble par des éléments circulaires, et ces deux ensembles indépendants sont ensuite rassemblés et 15 emboités l'un dans l'autre et solidarisés. Les dessins annexés illustrent la possibilité de conception et de fabrication de ces roues hybrides turbine hélice. Le dessin Fig.1 montre une roue fabriquée selon le procédé. Les dessins Fig.2 et 3 complémentaires montrent deux lames qui partent au centre de la 20 roue (0) ouvertes gueule bée au début (1) qui se referment en formant un conduit fermée convexe (2, BB) ou concave (3, BB). Ils montrent aussi que la pale de l'intrados part décalée sur l'axe (C) et en retrait (AA) Sur le dessin 4 de la Fig 3, il est montré que le bord de fuite de l'intrados est en retrait du bord de fuite de l'extrados et que le bord d'attaque de l'intrados qui est en retrait du bord 25 d'attaque de l'extrados (G) est adouci par un bord arrondi. La figure 2 montre que la pale est recourbée et orientée vers l'arrière (F) afin d'incliner la sortie à la demande. Elle montre aussi que les pales sont entourées par un élément circulaire, par exemple une bague (E) sur leur plus grand diamètre.The blades in the center when open are secured to at least one common solid element allowing the connection inside with other elements for rotation. The parts of the blades of the hollow propeller, located at its largest diameter, are often bent towards the rear of the wheel, and inclined to direct the exit of the duct (F). Commonly the propeller blades are secured to each other by at least one circular ring (E) which preferably surrounds them at the larger diameters of the wheel. To allow the industrial manufacture of thrusters the blades of the extrados of the propeller blades are assembled and joined together only by circular elements, and the blades of the intrados of the propeller blades are assembled and joined together only by circular elements, and these two independent assemblies are then assembled and nested one inside the other and secured. The accompanying drawings illustrate the possibility of design and manufacture of these hybrid turbine propeller wheels. The drawing Fig.1 shows a wheel manufactured according to the method. The complementary drawings Fig.2 and 3 show two blades which start at the center of the wheel (0) open mouth open at the beginning (1) which close again forming a closed convex duct (2, BB) or concave (3, BB ). They also show that the blade of the intrados part offsets on the axis (C) and recessed (AA) In the drawing 4 of Fig 3, it is shown that the trailing edge of the intrados is set back from the trailing edge of the upper surface and that the leading edge of the intrados which is set back from the leading edge of the extrados (G) is softened by a rounded edge. Figure 2 shows that the blade is bent and oriented rearward (F) to tilt the outlet on demand. It also shows that the blades are surrounded by a circular element, for example a ring (E) on their largest diameter.
