Definitions

  • the field of the present invention is that of sealing belts for arrow projectiles.
  • An arrow projectile is composed in a known manner of an under-calibrated penetrator secured to a caliber shoe.
  • the sabot is made up of several segments (generally three), which separate and release the indenter at the exit of the barrel of the weapon under the action of aerodynamic forces.
  • this function is fulfilled by the belt, and on the other hand between the different segments of the sabot this function is fulfilled by a elastomeric seal deposited on the shoe and tearing during the separation of the segments.
  • Patent DE2537116 describes a sub-calibrated projectile, the shoe of which has a one-piece rear part. The latter achieves both gas tightness and support of the belt. However, the breaking characteristics of such a shoe are difficult to master and such a solution cannot be transposed to arrow munitions having a rear seal made of elastomer.
  • Patent DE3332675 proposes to provide a seal which hooks at a rear shoulder of the shoe, but such a configuration does not prevent gas leakage in the event of cracking of the belt.
  • the invention relates to a sealing belt for a shoe of an arrow projectile which is characterized in that that it comprises on the one hand a substantially annular rear zone on which comes into contact, when the belt is placed in an annular groove of the shoe, a seal integral with the shoe, and on the other hand means ensuring its mechanical connection by form matching with the material of the joint.
  • a first advantage of such a configuration is that the seal, by coming into contact with a rear annular zone of the belt, will isolate the latter from the propellant gases and ensure sealing in the event of cracking of the belt.
  • Another advantage is that the means ensuring the mechanical joining by matching the shape of the belt with the material constituting the seal will prevent the seal from being torn off during the course of the projectile in the barrel of the weapon.
  • the securing means comprise recesses regularly distributed over the periphery of the belt, produced in a substantially radial direction of the latter and opening out at the rear zone, the shape of these recesses being such that it presents from the rear zone at least one narrowed zone followed by an enlarged zone.
  • the recesses may be substantially cylindrical holes whose axis is disposed at a distance from the rear zone which is less than their radius.
  • the securing means comprise appreciably cylindrical bores, regularly distributed and opening out at the rear zone, the axis of these bores is inclined relative to that of the belt, and advantageously it intersects the axis of the belt in front of the rear zone relative to the projectile.
  • the belt comprises at the rear zone a substantially cylindrical extension which is coaxial with it and the securing means comprise holes made on the extension in a substantially radial direction and regularly distributed over at least one circumference of the extension.
  • the cylindrical extension comprises a fracture initiator disposed behind the bores, which can be constituted by a thinned zone of the extension on which holes are made in a substantially radial direction and regularly distributed over a circumference.
  • the belt according to this third embodiment is particularly suitable for carrying on its cylindrical extension a ring intended to secure the projectile with a socket, in this case the holes open out between the annular zone of the belt and the ring, and the joint seal fills the space between the ring and the annular area.
  • Figure 1 shows schematically in half-view an arrow projectile equipped with a belt according to a first embodiment.
  • Figure 2 is a view of the previous one in direction F.
  • Figures 3A, 3B and 3C are views of the belt alone.
  • FIG. 4 represents a variant of the previous embodiment.
  • Figures 5A and 5B show the belt alone according to a second embodiment of the invention.
  • FIG. 6 schematically represents an arrow projectile equipped with a belt according to a third embodiment.
  • Figure 7 is a view of the belt of Figure 6 shown alone.
  • Figure 8 is a variant of this third embodiment of the belt.
  • an arrow projectile 1 is conventionally constituted by a shoe 2, comprising several segments, generally three, and in which is disposed an indenter 3 of heavy material, for example depleted uranium.
  • the different segments of the sabot are held by a front hoop 4 and a belt 5 which is intended to seal between the barrel of the weapon and the projectile during firing.
  • Front hoop and belt are arranged in annular grooves 9 and 10 made on the shoe, and are of the tube caliber, their installation is carried out by injection directly on the shoe arranged in a suitable mold.
  • a rear seal 6 provides sealing between the joint planes of the shoe segments, and between the shoe and the indenter.
  • This seal is for example obtained by injection of an elastomer (such as a polymer vulcanizable at high temperature) on the assembled shoe and placed in a suitable mold.
  • an elastomer such as a polymer vulcanizable at high temperature
  • the seal includes an outer lip 7 slightly over-calibrated (of the order of 121 mm for a caliber of 120 mm), and it comes into contact with the belt 5 at a rear annular zone 8 thereof.
  • the seal 6 could possibly not have a lip but in this case the external diameter of the seal will nevertheless be close to the external diameter of the belt and therefore therefore greater than the caliber of the barrel of the weapon. The external part of the seal will therefore be in contact with the internal surface of the barrel of the weapon.
  • the contact of the seal at the level of the annular zone 8 makes it possible to avoid any leakage of propellant gases between the seal and the belt and also prevents leaks from propagating between the barrel of the weapon and the belt in the event that would occur cracking of the latter.
  • annular area 8 is carried by an annular flange 11 and has recesses 12 regularly distributed over its periphery.
  • These recesses are cylindrical holes 12, produced in a substantially radial direction of the belt, and passing through the flange 11.
  • the belt here has nine holes 12 regularly distributed.
  • a number of holes which is preferably a multiple of the number of shoe segments, and we mean by regular distribution a distribution ensuring a position of the center of gravity of the belt substantially on its axis 15 (axis of the projectile).
  • the axis of these holes is arranged at a distance d (FIG. 3B) which is less than the radius of the holes, thus the holes open out at the level of the rear annular zone 8.
  • Such an arrangement makes it possible to obtain recesses which have, from the rear zone 8 at least one narrowed zone (here the opening of the holes on the rear zone 8) followed by an enlarged zone (the diameter of the holes).
  • the material constituting the seal will, during its injection, penetrate into the recesses, and the narrowing of the latter will make it possible to mechanically retain the seal.
  • the recesses then constitute a means ensuring the mechanical joining by matching the shape of the belt with the material of which the seal is made.
  • FIG. 4 shows, in uncut external view, an alternative embodiment in which the recesses 12 which are produced on the collar in a radial direction have a trapezoidal section.
  • FIGS. 5A and 5B show a second embodiment of the invention in which the belt 5 carries, at the level of the annular zone 8, substantially cylindrical bores 13, and regularly distributed (here nine bores).
  • the axes 14 of these holes are inclined relative to the axis 15 of the belt 5 (and therefore to the axis of the projectile).
  • the axes 14 are inclined so that they intersect the axis of the belt in front of the annular zone 8.
  • the material of the seal will penetrate these holes which will constitute a means of securing the seal and the belt, the resistance of this means is ensured by the inclination of the axes of the holes.
  • FIG. 6 shows a third embodiment, in which the belt comprises at the rear zone 8 a cylindrical extension 16 which is coaxial with it and whose diameter is less than the gauge.
  • This extension carries bores 17, regularly distributed, produced on a circumference of the extension in a substantially radial direction and in the vicinity of the rear annular zone 8.
  • the holes are cylindrical and tangent to the annular zone 8, but any other shape would be possible.
  • the holes thus constitute the means for securing the belt and the seal.
  • the extension 16 can advantageously be used to attach a connecting ring 19 to the projectile which will allow the assembled projectile to be secured with a socket containing the propellant charge (not shown here).
  • a connecting ring 19 is described in patent application FR2620214.
  • first fixing means not shown here which will be, for example, rivets arranged in holes 20 regularly distributed over a circumference of the extension and coming opposite other holes carried by the ring 19.
  • the ring is fixed to the sleeve by a second fixing means of the type described in patent application FR2620214 (for example rivets and an intermediate piece).
  • the fixing means will be dimensioned so that the rupture of the second means occurs under the effect of the pressure of the propellant gases, the first means not breaking.
  • the holes 17 will also be dimensioned in such a way that the rupture of the extension 16 occurs, where appropriate, preferably at the level of the studs 20 and the first means of fixing the ring 19.
  • the seal fills the entire space between the ring 19 and the annular zone 8 of the belt and it is pinched between these two elements, it then acts as a shock absorber of the vibrations that the socket transmits to the projectile through the ring, thereby reducing the mechanical stresses at the projectile ring connection and increasing the resistance and the service life of this connection.
  • FIG. 8 shows an alternative embodiment in which the holes 17 are distributed over a circumference situated in a radial plane 21.
  • Holes 24 are distributed over a circumference situated in another radial plane 22.
  • the extension 16 also has a thinned zone 23 at the holes 17 and the holes 24.
  • the material constituting the seal 6 only penetrates into the holes 17 located in the plane 21, the holes 24 located in the plane 22 are free.
  • the thinned zone 23 constitutes a primer for rupture allowing the separation of the belt 5 from the ring 19.
  • the rupture will occur at the level of the plane 22 in which are the holes 24 which are not filled with the material of the joint, that is to say behind the holes 17 which will continue to fulfill their function of securing the joint and the belt .
