Description

La présente invention concerne un distributeur de projectiles pour lanceur centrifuge.The present invention relates to a projectile distributor for a centrifugal launcher.

Le type de lanceur centrifuge envisagé ici est substantiellement constitué par un rotor incluant un canon cylindrique, ce rotor ayant une zone centrale ouverte dans laquelle débouche une extrémité du canon pourvue d'une palette de cueillage. Le but du distributeur selon l'invention est d'amener des projectiles oblongs successivement dans la trajectoire de ladite palette de manière à permettre leur prise en charge par cette dernière et, dès lors, leur éjection au travers du canon.The type of centrifugal launcher envisaged here is substantially constituted by a rotor including a cylindrical barrel, this rotor having an open central zone into which opens one end of the barrel provided with a picking pallet. The purpose of the dispenser according to the invention is to bring oblong projectiles successively in the trajectory of said pallet so as to allow their handling by the latter and, therefore, their ejection through the barrel.

A cet effet, le distributeur selon l'invention est substantiellement constitué par la combinaison : d'un support portant un élément couloir destiné à recevoir une pluralité de projectiles oblongs disposés côte-à-côte, ce couloir aboutissant à une zone de transfert aménagée dans ledit support; une glissière disposée dans ladite zone de transfert; une pièce d'appui, portée par ledit support et située face à ladite glissière dans la partie centrale ouverte du rotor; un moyen pour refouler périodiquement la glissière en synchronisme avec la rotation du rotor, vers une position avancée où elle obture ledit couloir; un moyen de rappel de la glissière vers une position rétractée où elle dégage ledit couloir; un moyen de verrouillage pour maintenir temporairement la glissière en position avancée à l'encontre dudit moyen de rappel; et un moyen de refoulement des projectiles dans ledit couloir vers ladite zone de transfert.To this end, the dispenser according to the invention is substantially constituted by the combination of: a support carrying a corridor element intended to receive a plurality of oblong projectiles arranged side by side, this corridor leading to a transfer zone arranged in said support; a slide arranged in said transfer zone; a support piece, carried by said support and located opposite said slide in the open central part of the rotor; means for periodically driving back the slide in synchronism with the rotation of the rotor, towards an advanced position where it closes said passage; means for returning the slide to a retracted position where it releases said passage; locking means for temporarily holding the slide in the advanced position against said return means; and one means for discharging the projectiles in said corridor towards said transfer zone.

Pour mieux faire apparaître les caractéristiques de l'invention, un exemple de réalisation est décrit ci-après à titre purement illustratif et non restrictif, référence étant faite aux dessins annexés, dans lesquels :

  • la figure 1 est une vue en élévation d'un lanceur centrifuge équipé d'un distributeur selon l'invention;

  • la figure 3 est une coupe selon la ligne III-III de la figure 2, ligne suivant le pourtour de la partie centrale de ladite figure 2; et
  • la figure 4 enfin est une vue selon la flèche F4 de la figure 3.
To better show the characteristics of the invention, an exemplary embodiment is described below for purely illustrative and not restrictive, reference being made to the appended drawings, in which:
  • Figure 1 is an elevational view of a centrifugal launcher equipped with a distributor according to the invention;
  • Figure 2 is an enlarged view of the central part of Figure 1, located by line II-II of Figure 3;
  • Figure 3 is a section along line III-III of Figure 2, line along the periphery of the central part of said Figure 2; and
  • FIG. 4 is finally a view according to arrow F4 in FIG. 3.

Un type de lanceur centrifuge auquel peut être appliquée l'invention est schématisé à la figure 1. Il est constitué par un rotor 1 contenant un canon cylindrique 2, le tout pouvant être entraîné en rotation par exemple par une turbine non représentée. Le rotor 1 a une zone centrale ouverte dans laquelle s'étend une palette de cueillage 3 prolongeant le canon 2. L'axe de ce dernier et l'axe de rotation du rotor 1 sont deux droits gauches. On trouvera plus de détails de cette construction dans le brevet belge n° 886.482.A type of centrifugal launcher to which the invention can be applied is shown diagrammatically in FIG. 1. It consists of a rotor 1 containing a cylindrical barrel 2, the whole being able to be driven in rotation for example by a turbine not shown. The rotor 1 has an open central zone in which extends a picking pallet 3 extending the barrel 2. The axis of the latter and the axis of rotation of the rotor 1 are two left-hand rights. More details of this construction can be found in Belgian Patent No. 886,482.

Un carénage de protection 4 entoure le rotor 1 et est monté angulairement réglable sur le support 5. Le carénage 4 porte un dispositif redresseur 6 destiné à assurer une attitude correcte des projectiles après que ceux-ci aient quitté le canon 2.A protective fairing 4 surrounds the rotor 1 and is mounted angularly adjustable on the support 5. The fairing 4 carries a rectifier device 6 intended to ensure a correct attitude of the projectiles after they have left the barrel 2.

Le distributeur 7 selon l'invention a pour fonction d'amener des projectiles 8 un à un dans la trajectoire de la palette de cueillage 3 qui les prend en charge permettant ainsi leur pénétration dans le canon 2 sous l'effet de la force centrifuge et donc leur éjection.The distributor 7 according to the invention has the function of bringing projectiles 8 one by one in the trajectory of the pallet of picking 3 which supports them thus allowing their penetration into the barrel 2 under the effect of centrifugal force and therefore their ejection.

Le distributeur 7 est constitué par un élément couloir 9 fixé à un support 10 et aboutissant à une zone de transfert 11 prévue dans ce dernier.The distributor 7 is constituted by a corridor element 9 fixed to a support 10 and leading to a transfer zone 11 provided in the latter.

Le couloir 9 est destiné à recevoir une pluralité d'obus oblongs 8 disposés côte-à-côte.The corridor 9 is intended to receive a plurality of oblong shells 8 arranged side by side.

Dans la zone de transfert 11 est logée une glissière 12 susceptible d'être déplacée dans un sens par le bossage 13 d'une came 14 et, dans l'autre sens, par des ressorts de rappel 15. Cette came est entraînée par l'arbre d'entraînement 16 du rotor 1, via un axe-pignon 17 attaquant une couronne dentée 18 solidaire de la came 14.In the transfer zone 11 is housed a slide 12 capable of being displaced in one direction by the boss 13 of a cam 14 and, in the other direction, by return springs 15. This cam is driven by the drive shaft 16 of the rotor 1, via a pinion pin 17 driving a toothed ring 18 secured to the cam 14.

Le rappel de la glissière 12 sous l'effet des ressorts 15 peut être empêché par un couteau-butée 19 porté en bout d'une bascule 20 pivotée en 21 sur un électro-aimant décrit ci-après et porté par le support 10.The return of the slide 12 under the effect of the springs 15 can be prevented by a stop knife 19 carried at the end of a rocker 20 pivoted at 21 on an electromagnet described below and carried by the support 10.

Un ressort 22 sollicite la bascule vers une position dans laquelle le couteau-butée s'oppose au rappel de la glissière 12. L'action du ressort 22 peut être contrecarrée par un électro-aimant 23 fixé au support 10. Ce dernier porte encore un élément d'appui ou enclume 24 située face à la glissière 12 et à une distance de l'entrée de la zone de transfert 11 sensiblement égale au calibre des projectiles 8.A spring 22 urges the rocker towards a position in which the knife-stop opposes the return of the slide 12. The action of the spring 22 can be counteracted by an electromagnet 23 fixed to the support 10. The latter still carries a support element or anvil 24 situated opposite the slide 12 and at a distance from the entrance to the transfer zone 11 substantially equal to the caliber of the projectiles 8.

La zone indiquée en 25 à la figure 3 est traversée périodiquement par la palette 3 du canon 2, lors de la rotation du rotor 1.The zone indicated at 25 in FIG. 3 is periodically crossed by the vane 3 of the barrel 2, during the rotation of the rotor 1.

Enfin, un vérin 26 pousse constamment les projectiles 8 se trouvant dans le couloir 9 vers la zone de transfert 11.Finally, a jack 26 constantly pushes the projectiles 8 located in the corridor 9 towards the transfer zone 11.

Le fonctionnement du distributeur 7 est comme suit.The operation of the distributor 7 is as follows.

La position "de repos" de la glissière 12 est celle la plus proche de l'enclume 24, position dans laquelle elle est maintenue par le couteau-butée 19 aussi longtemps que l'électro-aimant 23 n'est pas excité. La glissière 12 s'oppose alors à la sortie d'un projectile du couloir 9 sous l'effet du vérin 26.The "rest" position of the slide 12 is that closest to the anvil 24, position in which it is maintained by the knife-stop 19 as long as the electromagnet 23 is not energized. The slide 12 then opposes the exit of a projectile from the corridor 9 under the effect of the jack 26.

Pour amener un projectile contre l'enclume 24, donc pour tirer, l'électro-aimant 23 est brièvement excité ce qui entraîne la levée du couteau-butée 19, le rappel de la glissière 12 par les ressorts 15 et l'entrée d'un projectile dans la zone de transfert 11. Le bossage 13 de la came 14 refoule immédiatement la glissière 12 qui elle-même refoule le projectile parvenu dans la zone de transfert 11 contre l'enclume 24 position dans laquelle il peut être pris en charge par ladite palette 3 lorsque celle-ci traverse la zone 25.To bring a projectile against the anvil 24, therefore to fire, the electromagnet 23 is briefly excited which causes the lifting of the knife-stop 19, the return of the slide 12 by the springs 15 and the entry of a projectile in the transfer zone 11. The boss 13 of the cam 14 immediately repels the slide 12 which itself repels the projectile which has reached the transfer zone 11 against the anvil 24 position in which it can be supported by said pallet 3 when the latter crosses zone 25.

La fréquence de l'excitation de l'électro-aimant 23 détermine la cadence de tir. La valeur maximale de celle-ci est fonction de la vitesse de rotation de l'axe 16, du rapport de démultiplication entre le pignon 17 et la couronne 18 et du nombre de bossages 13 prévus sur la came 14.The frequency of the excitation of the electromagnet 23 determines the rate of fire. The maximum value of the latter is a function of the speed of rotation of the axis 16, the reduction ratio between the pinion 17 and the crown 18 and the number of bosses 13 provided on the cam 14.

L'alimentation de l'électro-aimant peut être commandée par un circuit à porte ET, cette dernière devenant conductrice dès arrivée de deux signaux : un ordre de tir et une détection de la position angulaire du canon 2 par rapport à celle de l'ensemble carénage 4 - redresseur 6 - distributeur 7, cette dernière déterminant la hausse de tir. En effet, pour obtenir une hausse voulue, il suffit de faire pivoter l'ensemble carénage 4 - redresseur 6 - distributeur 7 d'un angle voulu autour de l'axe du rotor, c'est-à-dire de l'axe du pignon 17.The supply of the electromagnet can be controlled by an AND gate circuit, the latter becoming conductive upon arrival of two signals: a firing order and a detection of the angular position of the barrel 2 relative to that of the fairing assembly 4 - rectifier 6 - distributor 7, the latter determining the increase in firing. In fact, to obtain a desired increase, it suffices to rotate the fairing assembly 4 - rectifier 6 - distributor 7 by a desired angle around the axis of the rotor, that is to say of the axis of the pinion 17.

Il est évident que de très nombreuses modifications peuvent être apportées à l'exemple susdécrit sans pour autant sortir du cadre de l'invention. Ainsi le mécanisme d'alimentation (couloir 7, vérin 26) pourrait être remplacé par un autre système permettant un chargement plus commode d'un plus grand nombre de projectiles.It is obvious that very many modifications can be made to the above-mentioned example without going out of the scope of the invention. Thus the feed mechanism (lane 7, cylinder 26) could be replaced by another system allowing more convenient loading of a larger number of projectiles.
