Definitions

  • the technical field of the invention is that of projectile sealing belts and in particular that of slipping belts.
  • the belt 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.
  • 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.
  • 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.
  • the patent FR2606869 describes such a slip belt.
  • 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.
  • 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.
  • the ring may be made of copper.
  • the ring may have a thickness less than or equal to 5% of the caliber.
  • 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.
  • 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.
  • 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.
  • the support 5 comprises a rear bearing surface 5b on which is placed a slip ring 6 made of plastic material.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • This spacer is made for example of aluminum.
  • 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.
  • 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.
  • 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.
