Definitions

  • the invention relates to ammunition, in particular for artillery, comprising a projectile linked to a shell containing a propellant charge.
  • the mode of connection between a projectile and a cartridge most often encountered is crimping.
  • An annular deformation of the sleeve encloses the projectile and immobilizes it both in rotation and in translation.
  • the projectile is kept at its rear part; thus, the case does not interfere with the engagement of the latter in the barrel of the weapon during the positioning of the ammunition in the chamber.
  • the object of the invention is to overcome these drawbacks by proposing a munition whose projectile is fixed on the socket according to conventional methods, but whose tilting with respect to the socket is prevented, and for which the forces to which the subject is subjected. crimping are decreased. It is another object of the present invention to also prohibit the loosening of an under-calibrated projectile, in particular of an arrow, relative to its hoof.
  • the subject of the invention is an ammunition in particular for artillery comprising a projectile linked to a shell containing a propellant charge, characterized in that it comprises a ring made of combustible material or else fragmentable under the effect of the pressure due to combustion of the propellant charge, integral with the projectile by a connecting means and whose lateral surface is adjusted to the interior surface of the case.
  • connection means between the ring and the projectile is constituted by a surface of the ring having a shape agreement with a part of the sub-projectile.
  • the ring will advantageously include a shoulder which will be pinched between the sub-projectile and the shoe.
  • the ammunition may include a means of securing in rotation between the shoe and the sub-projectile; this means may be constituted by an area of the ring having a shape concordance with a part of the shoe.
  • the ring is made integral with the sleeve at its lateral surface by a fixing means, for example a crimping.
  • the ring has a flat face coming into contact with the propellant charge and making a setting of the latter.
  • Figure 1 partially shows and in longitudinal section an arrow type ammunition constituted by a projectile 1, comprising a launch shoe 3 and a sub-projectile 2, threaded to the shoe, and having at its rear part a tail 13; the ammunition also comprises a metallic or combustible case 10, containing a propellant charge 11, some grains of which are schematically represented and which is in contact with the tail unit 13.
  • a projectile 1 comprising a launch shoe 3 and a sub-projectile 2, threaded to the shoe, and having at its rear part a tail 13; the ammunition also comprises a metallic or combustible case 10, containing a propellant charge 11, some grains of which are schematically represented and which is in contact with the tail unit 13.
  • This arrow munition is designed to be drawn in a rifled tube and it comprises for this purpose a slip belt 4 constituted by a belt body 5 free to rotate on a sub-ring 7 disposed in a housing 24 produced on the shoe 3.
  • the slip belt 4 also includes a front grain 6, a rear grain 9, as well as an axial locking means constituted by pins 8 fixed radially on the shoe 3.
  • a slip belt of this type is described in detail in the French patent. No. 86.16066.
  • the sleeve 10 is fixed by a crimp 16 on a rear annular extension of the belt body 5. This arrangement makes it easier to place the belt on the shoe.
  • the ammunition also comprises a ring 12, comprising a cylindrical lateral surface 15 fitted to the internal surface 14 of the sleeve 10. This ring is fixed in the vicinity of the crimp 16 to define a zone of contact with the sleeve at a certain distance from it. this.
  • This ring 12 has a bore 17 fitted tight on the sub-projectile 2 as well as radial grooves 18 in which is housed the tail 13 (see Figures 2 and 3); it also includes a shoulder 19 which is clamped between a bearing face 20 of the sub-projectile and a bearing face 21 of the shoe.
  • the ring comprises, on an area facing the shoe, notches 22 which have a shape agreement with the pins 8, and on its part facing the propellant charge 13, a flat face 23 which is pierced with a number of through holes 26 regularly distributed.
  • the ring must not interfere with the interior and exterior ballistics of the projectile and it will be made of a combustible material or even fragmentable under the effect of the pressure due to the combustion of the propellant charge. This material must also have sufficient rigidity to properly perform its functions.
  • a material of the low density polyethylene foam type having a density of the order of 100 to 150 kg / m 3 is perfectly suitable, or a polyamide of the 6 ⁇ 6 type, or a cardboard impregnated with a resin, or a cardboard fuel impregnated with nitrocellulose.
  • the holes 26 make it easier to destroy the ring and give a better balance of pressures on the belt 4.
  • the propellant charge 11 which is constituted by a number of grains, acts on the tail 13 by causing a rotation of the sub-projectile 2 relative to the shoe 3; this rotation causes a translation of the sub-projectile due to the connection by thread between the shoe and the latter.
  • the ring 12 is integral with the sub-projectile 2, the connecting means here being constituted by, both a tight fit of the bore 17 on the sub-projectile, and a concordance of shape between the tail 13 and the grooves 18; in addition, the ring is made integral in rotation with the shoe 3.
  • the rotational securing means here consists of a shape match between the notches 22 and the pawns 8, themselves integral with the hoof; thus, any rotation of the sub-projectile caused by the vibrations of the propellant charge, causes a rotation of the shoe (made possible by the slip belt); there is therefore no loosening of the sub-projectile.
  • the latter retains its initial axial position relative to the hoof, the maintenance of this position being essential for the sub-projectile to have good ballistic behavior at the start of the shot.
  • the ring In the case where the projectile does not have a slip belt, the ring always fulfills its function of securing in rotation the shoe and the sub-projectile.
  • the shoulder 19 pinched between a bearing face 20 of the sub-projectile and a bearing face of the shoe makes it possible to ensure correct positioning when the sub-projectile is mounted relative to the shoe.
  • the distance D between the center of gravity G of the projectile and the crimp 16 is of the order of 100 mm for an arrow munition (and nearly 200 mm for a hollow charge ammunition); the width of the crimping, it is of the order of 3 to 6 mm, the mass of the projectile being of the order of 3.5 kg; the mechanical forces supported by the crimping when the ammunition is horizontal and stressed in vibrations, jolts or twists, and shocks are significant and can reach several thousand Newton.
  • the use of a slip belt on which the socket is crimped causes the tip of the projectile to tilt a few mm because of the axial and radial clearances (of the order of a tenth of a mm) that may exist between the belt body and its housing; in addition to the discomfort brought by this tilting to the installation of the ammunition, the freedom to tilt left to the projectile risks increasing the amplitude of the vibrations and the efforts therefore the stresses undergone by the crimping.
  • the ring according to the invention has an external lateral surface 15 fitted to the internal surface 14 of the sleeve; the ring being integral with the projectile, it allows the latter to be pressed behind the crimp.
  • a length 1 of the order of size is preferably chosen.
  • the material constituting the ring also acts as a shock absorber for the vibrations of the projectile.
  • the flat face 23, facing the propellant charge 11, ensures the timing of the latter.
  • Figure 4 shows an alternative embodiment of the invention, in which the connecting means between the ring 12 and the projectile is constituted by the surface of the bore 17, as well as that of the grooves 18, as before; but in this, the rotational securing means is constituted by the combination of crimping 16 of the sleeve on the belt, of the sleeve itself, and of crimping 25 of the sleeve on the ring 12.
  • the vibrations of the propellant charge cannot pivot the sub-projectile 2, the latter being integral with the ring 12, itself made integral with the sleeve 10 at its lateral surface by crimping 25; the sub-projectile is therefore integral in rotation and in translation with the sleeve 10.
  • the shoe is also immobilized in rotation and in translation. Indeed, a rotation of the hoof is only possible if a relative translation hoof-sub-projectile is possible or else if the sub-projectile is both free in translation and linked in rotation to the hoof; the sub-projectile being completely immobilized with respect to the sleeve, any relative movement of rotation or translation of the shoe relative to the sub-projectile is impossible.
  • the joining of the ring and the socket for ra optionally be carried out by another fixing means, for example by bonding or not associated with crimping.
  • the surfaces of the ring having shape matches with a part of the shoe can be different and in particular can be adapted to a particular shape of the rear part of the shoe.
  • the invention can be applied to ammunition of medium caliber as well as to ammunition comprising a projectile with a hollow charge and carrying a slip belt, or even to an explosive shell with a fixed belt, the main aim sought being to reduce the stresses at the level of the socket crimping on the projectile.
