Definitions

  • the present invention relates to armor-piercing projectiles for guns having a barrel provided with rifles, such projectiles including a core of a hard material surrounded by an ogive made at least partly of a light material, the terms light material” including not only light metals and alloys but also all other substances such as plastic materials having a density substantially lower than that of steel.
  • the invention is more especially concerned with armorpiercing shells of small calibre.
  • the chief object of the present invention is to provide a projectile of this type which is better adapted to meet the requirements of practice, not only from the point of view of their armor-piercing properties but also from the point of view of the preservation of the barrel of the gun from which they are fired.
  • the ogive of such a projectile includes a rear portion of a cross-section smaller than the maximum cross-section of the front portion of said ogive, this rear portion, which surrounds the rear portion of the core, being itself surrounded by a base also made of a light material, said base including a rearward extension surrounded by a ring of a hard material in which is fixed at least one driving or rotating band for giving the projectile its spin.
  • the essential element of this projectile which is to perform the armor-piercing function thereof, is a core 1, having a pointed front end, which should of course store up the maximum possible of kinetic energy under the smallest possible volume so that it is made of a high density material (hard sintered metal, tungsten carbide and so on
  • This ogive includes the following portions: on the one hand, a sharp front portion 2 adapted to cover the point of the core and which advantageously leaves a free space between the ogive and the core in which can be packed a burning composition 3, for instance an incendiary one; this front portion 2 extends to the rear end of the ogive of the core, behind which said core becomes cylindrical, and on the other hand, a rear portion 4 substantially of cylindrical shape, surrounding the rear portion of the core, this rear portion 4 of the ogive being of a diameter smaller than that of the base of front portion 2.
  • This rear portion 4 of the ogive is engaged in the front portion 5 of a base also made of a light material, this front portion 5 having the shape of a hollow cylinder opened at the front, the outer wall of which has a diameter equal to the external diameter of the projectile, whereas its inner wall is a cylindrical wall adapted to fit on the rear portion 4 of the ogive.
  • This base includes, behind its front portion 5, an extension 6 in the form of a hollow cylinder opened at the rear; the outer wall of which is of a diameter smaller than the external diameter of the projectile, whereas its inner wall limits a recess adapted to receive a powder composition 7, for instance an incendiary one or a tracing one.
  • the rear portion of the projectile is guided in the gun barrel by two portions B and C of ring 10, said portions preferably having a diameter equal to that of the active area of ring 10.
  • the chief advantages of such a projectile are as follows: the ratio of the weight of core 1 to the total weight of the projectile which reaches about 54% for a 20 mm. shell as above described is very satisfactory since the armorpiercing projectiles thus obtained have substantially the same weight as shells of other types to be fired from the same gun; the portions of the projectiles made of light material do not risk to clog the inner wall of the gun barrel; accuracy of firing, due to the double guiding at the front at A and at the rear at B and C, remains unchanged during the travel of the projectile through the gun barrel.
  • a projectile which comprises, in combination, an armor piercing core, an ogive mounted on said core to surround it, said ogive being made of a material of a density much lower than that of said core, said ogive having a cylindrical rear portion of a cross section smaller than the maximum cross section of its front portion, the outer wall of said ogive forming, between said front portion and said rear portion thereof, a rearwardly facing annular shoulder, a cylindrical base fitting tightly around said ogive rear portion, said base being made of a material of at least approximately the same density as said ogive, the front edge of said base being at a distance from said shoulder and facing it, a solid front guiding ring of a material harder than that of said ogive fitted on the side wall of said rear portion of the ogive, extending from said shoulder to said base front edge and having an outer diameter slightly greater than that of said base and that of the outer edge of said shoulder, a rear cylindrical extension of said base integral therewith, said extension having an outer diameter smaller than that of said base and said
