Abstract

The seal band, comprising an anti-slip ring (6) that turns on a support (5), incorporates a copper ring (7) of the same diameter as the gun barrel. The copper ring, which has a thickness no more than 5 per cent of the barrel calibre, is located in front of the anti-slip ring and is of smaller diameter than the latter. It is held at a set distance from the anti-slip ring by a spacer (8).

Description

Le domaine technique de l'invention est celui des ceintures d'étanchéité pour projectile et notamment celui des ceintures dérapantes.The technical field of the invention is that of projectile sealing belts and in particular that of slipping belts.

Il est classique de doter un projectile d'une ceinture d'étanchéité. Celle ci est destinée à assurer lors du tir l'étanchéité vis à vis des gaz propulsifs entre le projectile et le tube de l'arme.It is conventional to equip a projectile with a sealing belt. This is intended to ensure when firing the seal against the propellant gases between the projectile and the tube of the weapon.

Lorsque le projectile est du type gyrostabilisé la ceinture est généralement métallique. Elle prend les rayures du tube de l'arme et communique un mouvement de rotation au corps de projectile. Cette configuration est celle généralement mise en oeuvre pour les tirs d'artillerie, les tubes d'artillerie étant toujours rayés.When the projectile is of the gyro-stabilized type, the belt is generally metallic. It takes the scratches from the barrel of the weapon and communicates a rotational movement to the projectile body. This configuration is the one generally used for artillery fire, the artillery tubes being always scratched.

On connaît également des projectiles qui ne sont pas gyrostabilisés mais stabilisés par empennage. Ce sont par exemple les obus sous calibrés, dits obus flèches, ou bien les obus au calibre dotés d'une charge formée.Projectiles that are not gyrostabilized but stabilized by empennage are also known. These are, for example, sub-calibrated shells, known as arrow shells, or caliber shells with a shaped charge.

Ces projectiles sont habituellement tirés par les canons de char à âme lisse et la ceinture du projectile est alors le plus souvent réalisée en matière plastique. Il n'y a pas alors lors du tir de mise en rotation du projectile dans le tube de l'arme.These projectiles are usually fired by the smooth-body tank guns and the projectile belt is then most often made of plastic. There is no then during the firing of rotation of the projectile in the tube of the weapon.

Lorsqu'un tel projectile doit être tiré à partir d'un tube rayé, il se pose le problème d'éviter son entraînement en rotation par le tube. Différentes solutions ont été envisagées pour cela, la plus classique est celle de la ceinture dite dérapante.When such a projectile is to be fired from a striped tube, there is the problem of avoiding its rotation in the tube. Different solutions have been envisaged for this, the most classic is that of the so-called slip belt.

Une telle ceinture comporte une bague glissante montée sur une sous bague fixe. La bague glissante est entraînée par les rayures du tube de l'arme mais elle dérape sur la sous bague et n'entraîne donc pas le projectile en rotation.Such a belt has a sliding ring mounted on a fixed under ring. The sliding ring is driven by the scratches of the barrel of the weapon but it skids on the under ring and therefore does not drive the projectile in rotation.

Le brevet FR2606869 décrit une telle ceinture dérapante.The patent FR2606869 describes such a slip belt.

On cherche aujourd'hui à tirer à partir de tubes d'artilleries (donc rayés) des projectiles à longue portée qui déploient un empennage sur trajectoire.Today, we are trying to fire long-range projectiles from artillery tubes (which are therefore striped), which deploy a feather on the trajectory.

Ces projectiles ne doivent pas être entraînés en rotation par le tube de l'arme. On a donc mis en oeuvre avec de tels obus les concepts de ceinture dérapante connus.These projectiles must not be rotated by the barrel of the weapon. Thus, with such shells, the known slip belt concepts have been implemented.

On se heurte cependant à une autre difficulté qui est l'impossibilité avec de telles ceintures d'assurer un coincement du corps de projectile dans le cône de forcement du tube de l'arme.However, one encounters another difficulty which is the impossibility with such belts to ensure a jamming of the projectile body in the cone forcing the tube of the weapon.

Ce problème ne se rencontrait pas avec les armements de véhicules blindés qui tirent des munitions encartouchées et avec des angles de site réduits (inférieurs à 30°).This problem did not occur with armored vehicle armaments firing ammunition and with reduced elevation angles (less than 30 °).

Dans le domaine de l'artillerie l'obus est introduit seul puis on met en place dans la chambre de l'arme un certain nombre de modules ou sacs de poudres propulsives.In the field of artillery the shell is introduced alone then we put in place in the room of the weapon a number of modules or bags of propellant powders.

Par ailleurs ce chargement en plusieurs fardeaux doit pouvoir se faire pour des angles de sites importants (de 30° à 50°) pour le tube de l'arme.Moreover this loading in several burdens must be able to be done for angles of important sites (of 30 ° to 50 °) for the tube of the weapon.

Les obus classiques à ceinture métallique sont introduits dans le cône de forcement et ils restent coincés à ce niveau par leur ceinture. La mise en place de la charge propulsive est alors possible sans risque de voir l'obus reculer et heurter la charge.Conventional shells with a metal belt are introduced into the forcing cone and they remain stuck at this level by their belt. The introduction of the propellant charge is then possible without risk to see the shell back and hit the load.

Un obus doté d'une ceinture dérapante en matière plastique rebondit sur le cône de forcement et il retombe dans la chambre de l'arme rendant impossible voire dangereuse la mise en place de la charge propulsive.A shell with a plastic sling belt rebounds on the forcing cone and it falls back into the chamber of the weapon making impossible or even dangerous the introduction of the propellant charge.

C'est le but de l'invention que de pallier de tels inconvénients en proposant une ceinture d'étanchéité dérapante adaptable à un projectile d'artillerie et permettant d'assurer le coincement de ce dernier dans le cône de forcement d'un tube d'arme.It is the object of the invention to overcome such drawbacks by proposing a slip-proof sealing belt that can be adapted to an artillery projectile and that makes it possible to jam the latter into the forcing cone of a gunner tube. 'armed.

Ainsi l'invention a pour objet une ceinture d'étanchéité pour projectile comprenant une bague dérapante montée tournante sur un support de ceinture, caractérisée en ce qu'elle comprend, en avant de la bague dérapante, un anneau de diamètre externe sensiblement au calibre du tube de l'arme et inférieur au diamètre de la bague dérapante.Thus, the subject of the invention is a projectile sealing belt comprising a slip ring rotatably mounted on a belt support, characterized in that it comprises, in front of the slip ring, a ring of external diameter substantially of the caliber of gun barrel and less than the diameter of the slip ring.

Avantageusement l'anneau pourra être réalisé en cuivre.Advantageously, the ring may be made of copper.

L'anneau pourra avoir une épaisseur inférieure ou égale à 5% du calibre.The ring may have a thickness less than or equal to 5% of the caliber.

L'anneau sera maintenu à distance de la bague dérapante par une entretoise dont la longueur sera choisie telle que l'anneau se trouve engagé dans les rayures du tube avant que la bague dérapante ne soit en contact avec le cône de forcement.The ring will be kept away from the slip ring by a spacer whose length will be chosen such that the ring is engaged in the scratches of the tube before the slip ring is in contact with the forcing cone.

Le support de ceinture pourra porter la bague, l'entretoise et l'anneau et assurera la fixation de l'ensemble sur une partie arrière d'un projectile.The belt support can carry the ring, the spacer and the ring and will ensure the attachment of the assembly on a rear part of a projectile.

L'invention sera mieux comprise à la lecture de la description qui va suivre de différents modes de réalisation, description faite en référence aux dessins annexés et dans lesquels :

  • la figure 1 est une vue partielle et en coupe de l'arrière d'un projectile équipé d'une ceinture selon l'invention,
  • la figure 2 représente ce même projectile mis à poste dans le tube d'un canon d'artillerie.
The invention will be better understood on reading the following description of various embodiments, a description given with reference to the appended drawings and in which:
  • FIG. 1 is a partial view in section of the rear of a projectile equipped with a belt according to the invention,
  • Figure 2 shows the same projectile placed in the tube of an artillery gun.

On a représenté sur la figure 1 une partie arrière d'un projectile 1 d'artillerie d'axe 1a. Cette partie arrière comporte une portée filetée 2 qui s'étend d'un épaulement 3 à un écrou d'arrêt 4. La portée filetée reçoit un support cylindrique 5 qui est réalisé par exemple en aluminium. Ce support vient en butée sur l'épaulement 3 et comporte un épaulement arrière 5a.FIG. 1 shows a rear part of an artillery projectile 1 with axis 1a. This rear portion comprises a threaded surface 2 which extends from a shoulder 3 to a lock nut 4. The threaded surface receives a cylindrical support 5 which is made for example of aluminum. This support abuts on the shoulder 3 and has a rear shoulder 5a.

Le support 5 comporte une portée arrière 5b sur laquelle est placée une bague dérapante 6 en matière plastique.The support 5 comprises a rear bearing surface 5b on which is placed a slip ring 6 made of plastic material.

La bague 6 est destinée à prendre les rayures du tube de l'arme (non représentée sur cette figure). Elle peut donc tourner par rapport au support 5 et forme avec ce dernier une ceinture dérapante. Le diamètre externe de la bague 6 est légèrement supérieur au diamètre à fond de rayure du tube de l'arme (de l'ordre de 158 mm), cela afin d'assurer l'étanchéité aux gaz propulsifs lors du tir.The ring 6 is intended to take the stripes of the barrel of the weapon (not shown in this figure). It can therefore rotate relative to the support 5 and form with the latter a slipping belt. The outer diameter of the ring 6 is slightly greater than the diameter at the bottom of scratch of the barrel of the weapon (of the order of 158 mm), in order to ensure the tightness of the propellant gases during firing.

Conformément à l'invention la ceinture comporte aussi un anneau 7, disposé en avant de la bague dérapante 5. Cet anneau a un diamètre externe sensiblement au calibre du tube de l'arme mais inférieur au diamètre de la bague dérapante 6.According to the invention the belt also comprises a ring 7, disposed in front of the slip ring 5. This ring has an outer diameter substantially the caliber of the tube of the weapon but less than the diameter of the slip ring 6.

Il a également un diamètre interne qui autorise son pivotement par rapport au support 5.It also has an internal diameter that allows it to pivot relative to the support 5.

Concrètement l'anneau 7 aura un diamètre légèrement supérieur au calibre (quelques dixièmes de mm) et il sera réalisé par exemple en cuivre.Concretely the ring 7 will have a diameter slightly greater than the caliber (a few tenths of a millimeter) and it will be made for example of copper.

L'épaisseur de l'anneau sera choisie relativement réduite, par exemple inférieure ou égale à 5% du calibre (soit de l'ordre de 6 mm) afin de ne pas occasionner de frottements trop importants lors du tir et ne pas gêner le dérapage de la bague 5.The thickness of the ring will be chosen relatively small, for example less than or equal to 5% of the caliber (ie of the order of 6 mm) so as not to cause excessive friction during firing and not to hinder the skid of the ring 5.

L'anneau 7 est maintenu à distance de la bague dérapante 5 par une entretoise 8 dont la longueur est choisie telle que l'anneau 7 puisse se trouver engagé dans les rayures du tube avant que la bague dérapante 5 n'arrive en contact avec le cône de forcement du tube. Généralement il suffira d'une entretoise ayant une longueur de l'ordre de 20 à 25% du calibre.The ring 7 is kept away from the slip ring 5 by a spacer 8 whose length is chosen such that the ring 7 can be engaged in the scratches of the tube before the slip ring 5 comes into contact with the forcing cone of the tube. Generally it will suffice a spacer having a length of the order of 20 to 25% of the caliber.

Cette entretoise est réalisée par exemple en aluminium.This spacer is made for example of aluminum.

Lorsque l'on visse le support 5 sur la partie filetée 2 du projectile 1 on vient appliquer la bague 7 contre l'épaulement 3 du projectile 1.When the support 5 is screwed onto the threaded portion 2 of the projectile 1, the ring 7 is applied against the shoulder 3 of the projectile 1.

Le support de ceinture 5 porte ainsi la bague 6, l'entretoise 8 et l'anneau 7 et il permet de fixer l'ensemble de la ceinture sur la partie arrière du projectile 1.The belt support 5 thus carries the ring 6, the spacer 8 and the ring 7 and it allows to fix the entire belt on the rear part of the projectile 1.

Le fonctionnement de la ceinture selon l'invention va maintenant être décrit en référence à la figure 2.The operation of the belt according to the invention will now be described with reference to FIG.

On a représenté sur cette dernière le projectile 1 mis à poste dans le tube 9 rayé d'un canon d'artillerie. On voit également sur cette figure la chambre 11 du canon et le cône de forcement 10 qui raccorde la chambre 11 à la partie rayée du tube 9.On the latter is shown the projectile 1 placed in the tube 9 striped with an artillery gun. This figure also shows the chamber 11 of the barrel and the forcing cone 10 which connects the chamber 11 to the striped part of the tube 9.

On constate que l'anneau 7 se trouve introduit en force au niveau des rayures du tube 9 (partie au calibre). Par contre la bague 6 est juste en contact avec le cône de forcement 10 et elle n'a pas encore été déformée.It is found that the ring 7 is introduced in force at the level of the scratches of the tube 9 (part of the caliber). By against the ring 6 is just in contact with the forcing cone 10 and it has not yet been deformed.

Le projectile est projeté généralement dans la chambre de l'arme par un système de chargement. L'impact qui en résulte a provoqué l'introduction de l'anneau 7 dans le tube 9 et sa déformation au passage du cône de forcement 10.The projectile is usually thrown into the chamber of the weapon by a loading system. The resulting impact has caused the introduction of the ring 7 in the tube 9 and its deformation at the passage of the forcing cone 10.

L'anneau 7 est dimensionné pour pouvoir passer le cône de forcement 10 et assurer le coincement du projectile pour tous les angles de sites et toutes les températures d'emploi prévues.The ring 7 is dimensioned to be able to pass the forcing cone 10 and ensure the jamming of the projectile for all the angles of sites and all the expected employment temperatures.

Ce coincement est obtenu sans que la bague dérapante 6 ne soit elle-même déformée. On évite ainsi tout phénomène de rebond du projectile lors de sa mise à poste et on assure un coincement fiable du projectile dans le tube sans détériorer la ceinture dérapante. On ne craint donc plus un décrochement intempestif du projectile qui viendrait impacter les charges propulsives avant le tir.This wedging is obtained without the slip ring 6 is itself deformed. This avoids any phenomenon of rebound of the projectile when it is put into position and ensures a reliable jamming of the projectile in the tube without damaging the slipping belt. One no longer fears an inadvertent detachment of the projectile that would impact the propulsive charges before firing.

L'Homme du Métier dimensionnera aisément les différents composants de la ceinture pour obtenir le fonctionnement souhaité dans lequel on sépare au niveau de la ceinture la fonction coincement du projectile de la fonction étanchéité par bague dérapante.The skilled person will easily size the various components of the belt to achieve the desired operation in which is separated at the waist of the projectile jamming function of the sealing function slip ring.
