Description

  • La présente invention concerne un rotor pour lanceur centrifuge.The present invention relates to a rotor for a centrifugal launcher.
  • Par lanceur centrifuge, il faut entendre dans le cadre de la présente une machine comportant une partie tournante ou rotor entraînée à grande vitesse autour d'un axe de rotation et équipée de moyens pour amener successivement des projectiles dans la zone centrale du rotor pour être substantiellement radialement éjectés de ce dernier par la force centrifuge.By centrifugal launcher is meant in the context of the present a machine comprising a rotating part or rotor driven at high speed around an axis of rotation and equipped with means for successively bringing projectiles into the central area of the rotor to be substantially radially ejected from the latter by centrifugal force.
  • Les lanceurs de ce type connus du Demandeur font pratiquement tous appel à des projectiles sphériques ou, bien plus rarement, en forme de disques. Ceci résulte des difficultés inhérentes à l'alimentation du lanceur, laquelle exige un contrôle parfait de chaque projectile, dans le temps et dans l'espace, au moment où il est abandonné au rotor. C'est la raison pour laquelle les projectiles sphériques ont été préférés car n'ayant aucun axe préférentiel.Launchers of this type known to the Applicant practically all use spherical or, more rarely, disc-shaped projectiles. This results from the difficulties inherent in feeding the launcher, which requires perfect control of each projectile, in time and space, when it is abandoned to the rotor. This is the reason why the spherical projectiles were preferred because having no preferential axis.
  • Les projectiles sphériques présentent néanmoins des limitations considérables dans le domaine militaire: limitation de la vitesse d'éjection; qualités balistiques peu favorables; impossibilité pratique d'être munis de charges explosives, etc ...Spherical projectiles nevertheless have considerable limitations in the military field: limitation of the speed of ejection; unfavorable ballistic qualities; practical impossibility of being provided with explosive charges, etc.
  • Dans un brevet relativement ancien (FR 796.149) est décrit un fusil centrifuge s'étendant à partir d'une chambre annulaire cylindrique et tangentiellement à cette dernière. L'ensemble est monté à rotation autour de l'axe de ladite chambre. Ce dernier et l'axe dudit canon sont dès lors deux droits gauches. Des projectiles oblongs, en forme substantiellement de goutte d'eau, sont successivement éjectés d'un magasin dans ladite chambre annulaire, une butée fixe étant prévue pour empêcher qu'un projectile projeté dans ladite chambre n'accompagne celle-ci dans sa rotation, ceci amenant le projectile à pénétrer dans ledit canon.In a relatively old patent (FR 796.149) a centrifugal rifle is described extending from a cylindrical annular chamber and tangentially to the latter. The assembly is mounted for rotation about the axis of said chamber. The latter and the axis of said barrel are therefore two left rights. Oblong projectiles, substantially in the form of a teardrop, are successively ejected from a magazine in said annular chamber, a fixed stop being provided to prevent a projectile projected in said chamber from accompanying it in its rotation, this causing the projectile to enter said barrel.
  • Outre des problèmes quasi insurmontables d'équilibrage et de résistance d'un tel dispositif si l'on envisage des vitesses de rotation élevées, ce dernier présente le défaut rédhibitoire de ne pas permettre un contrôle rigoureux de l'axe du projectile, entre l'instant où il choit dans la chambre et le moment où il pénètre dans le canon.In addition to the almost insurmountable problems of balancing and resistance of such a device if high rotation speeds are considered, the latter has the crippling defect of not allowing rigorous control of the axis of the projectile, between the instant he falls into the chamber and the moment he enters the barrel.
  • Le but de l'invention est de fournir un rotor permettant le lancement à très grande vitesse, dans de bonnes conditions, de projectiles oblongs dont la forme est extrêmement voisine de celle des obus classiques (c'est-à-dire avec queue, corps et tête ogivale). Une famille de projectiles adéquats dans le cadre de la présente invention est décrite dans une demande conjointe déposée par le même Demandeur (EP-A-53421).The object of the invention is to provide a rotor allowing the launch at very high speed, in good conditions, of oblong projectiles whose shape is extremely close to that of conventional shells (that is to say with tail, body and ogival head). A family of suitable projectiles in the context of the present invention is described in a joint application filed by the same Applicant (EP-A-53421).
  • A cet effet, un rotor selon l'invention, du type à canon cylindrique tournant autour d'un axe, se caractérise en ce que ledit canon est enserré entre deux flasques montés en bout d'un arbre d'entraînement, ces flasques présentant un espace central libre dans lequel aboutit l'extrémité du canon la plus voisine de l'axe de rotation.To this end, a rotor according to the invention, of the type with a cylindrical barrel rotating around an axis, is characterized in that said barrel is clamped between two flanges mounted at the end of a drive shaft, these flanges having a free central space into which ends the end of the barrel closest to the axis of rotation.
  • Cette extrémité interne du canon se prolonge par une palette de cueillage s'étendant jusqu'à proximité de l'axe de rotation dudit rotor.This internal end of the barrel is extended by a picking pallet extending as close to the axis of rotation of said rotor.
  • Ces dispositions permettent à ladite palette de cueillir tangentiellement et sans heurt chaque projectile convenablement présenté à cet effet à proximité dudit axe de rotation.These provisions allow said pallet to pick up tangentially and smoothly each projectile suitably presented for this purpose near said axis of rotation.
  • Le dispositif de présentation ne fait pas partie de l'invention. A titre indicatif, on pourra se référer à la demande 82201489E du même Demandeur.The presentation device is not part of the invention. As an indication, reference can be made to request 82201489E from the same Applicant.
  • Par canon cylindrique, il faut entendre, dans le cadre de la présente, un canon tubulaire ou semi-tubulaire à axe rectiligne ou substantiellement tel.By cylindrical barrel is meant, in the context of the present, a tubular or semi-tubular barrel with a straight axis or substantially such.
  • Pour plus de clarté, un mode de réalisation de l'invention est décrit ci-après à titre illustratif et non restrictif, référence étant faite aux dessins annexés, dans lesquels:
    • la figure 1 est une vue en élévation d'un lanceur selon l'invention; et
    • la figure 2 en est une coupe axiale.
    For greater clarity, an embodiment of the invention is described below by way of illustration and without limitation, reference being made to the appended drawings, in which:
    • Figure 1 is an elevational view of a launcher according to the invention; and
    • Figure 2 is an axial section.
  • Le lanceur représenté comporte un rotor 1 constitué par deux flasques 2 et 3 boulonnés l'un à l'autre et enserrant un canon cylindrique 4. Cet ensemble est monté et bout d'un arbre 5 porté par des roulements supportés par un bâti 6. Cet arbre 5 est susceptible d'être entraîné par un moteur, non représenté.The launcher shown comprises a rotor 1 constituted by two flanges 2 and 3 bolted to each other and enclosing a cylindrical barrel 4. This assembly is mounted and the end of a shaft 5 carried by bearings supported by a frame 6. This shaft 5 is capable of being driven by a motor, not shown.
  • Les flasques 2 et 3 sont chacun pourvus d'un alésage central, ce qui laisse un espace libre 7 au centre du rotor. Dans cet espace est engagée l'extrémité d'un dispositif d'alimentation et de présentation, schématisé en 8.The flanges 2 and 3 are each provided with a central bore, which leaves a free space 7 in the center of the rotor. In this space is engaged the end of a supply and presentation device, shown diagrammatically at 8.
  • Le canon 4 est disposé entre les flasques 2 et 3 de sorte que son axe X-X et l'axe de rotation Y-Y du rotor soient deux droites gauches. Dans cet exemple, les projections de ces droites dans le plan de la figure 2 sont en outre perpendiculaires entre elles.The barrel 4 is arranged between the flanges 2 and 3 so that its axis X-X and the axis of rotation Y-Y of the rotor are two left straight lines. In this example, the projections of these straight lines in the plane of Figure 2 are also perpendicular to each other.
  • Le canon 4 a une longueur telle que son extrémité la plus voisine de l'axe Y-Y aboutisse dans l'escape 7. Cette extrémité est pourvue d'une palette de cueillage 9 qui est en fait un prolongement d'une partie de la paroi du .canon 4, d'une largeur légèrement moindre que le calibre des projectiles 10. La longueur de ladite palette est légèrement supérieure à la distance séparant le centre de gravité d'un pro- jedtile 10 de la pointe de son ogive.The barrel 4 has a length such that its end closest to the YY axis ends in the escape 7. This end is provided with a picking pallet 9 which is in fact an extension of part of the wall of the .canon 4, of a width slightly less than the caliber of the projectiles 10. The length of said pallet is slightly greater than the distance separating the center of gravity of a projectile 10 from the tip of its warhead.
  • Le dispositif 8 comporte un chargeur 11 dans lequel des projectiles 10 sont alignés côte-à- côte et refoulés vers une butée 12. Un projectile appliqué contre la butée 12 est immédiatement pris en charge par la palette 9 qui, dans sa rotation, vient le cueillir tangentiellement et l'enlever d'entre la butée 10 et l'amenée du projectile suivant. Comme indiqué à la figure 1, le rotor tourne dans le sens horlogique et, dans sa rotation, la palette 9 vient se placer entre l'axe de rotation Y-Y et le projectile pour cueillir ce dernier.The device 8 comprises a magazine 11 in which projectiles 10 are aligned side-by-side and pushed back towards a stop 12. A projectile applied against the stop 12 is immediately supported by the pallet 9 which, in its rotation, comes to pick up tangentially and remove it between the stop 10 and the supply of the next projectile. As shown in Figure 1, the rotor rotates clockwise and, in its rotation, the pallet 9 is placed between the axis of rotation YY and the projectile for pick the latter.
  • Le rotor est entouré de deux flasques de protection 13 et 14 portant un dispositif de correction 15 nécessaire pour amener l'axe du projectile sur la trajectoire de son centre de gravité au moment de l'éjection.The rotor is surrounded by two protective flanges 13 and 14 carrying a correction device 15 necessary to bring the axis of the projectile onto the trajectory of its center of gravity at the time of ejection.
  • Dans l'exemple susdécrit, le canon est un tube d'acier cylindrique, ce qui est la solution préférée. On pourrait toutefois le remplacer par un aubage semi-cylindrique, sans pour autant sortir du cadre de l'invention.In the example described above, the barrel is a cylindrical steel tube, which is the preferred solution. It could however be replaced by a semi-cylindrical blading, without departing from the scope of the invention.
  • Dans le cas où le canon présenterait des faibles courbures, ce seraient la tangente à l'extrémité du canon voisine de l'axe de rotation et ce dernier qui formeraient deux droites gauches.In the case where the barrel would present weak curvatures, it would be the tangent at the end of the barrel close to the axis of rotation and the latter which would form two left straight lines.
  • Il est évident que le rotor est pourvu de masses d'équilibrage, non représentées pour la clarté des dessins. Un rotor selon l'invention, d'un diamètre de 950 cm, tournant à une vitesse de 12.443 t/m permet de communiquer à un projectile une vitesse d'éjection de 800 m/s.It is obvious that the rotor is provided with balancing weights, not shown for clarity of the drawings. A rotor according to the invention, with a diameter of 950 cm, rotating at a speed of 12,443 rpm allows to communicate to a projectile an ejection speed of 800 m / s.
