Definitions

  • the present invention relates to armour piercing and incendiary shells both of small caliber (in particular of a caliber ranging from 15 mm. to 50 mm.) and of large caliber (75, 105 and 150 mm., for instance).
  • Its chief object is to provide a projectile of this kind which is better adapted to meet the requirements of practice than those made up to this time.
  • the projectile includes at least two shell elements, containing each a charge, disposed one behind the other in tandem-like fashion, the front element including an explosive charge, whereas at least one of the elements includes an incendiary charge, the means for firing said explosive charge being operative in response to impact of said front element on an obstacle whereas the charge in the rear element is arranged to be fired only in response to direct impact of said rear element on an obstacle.
  • the rear element is given an armour piercing power higher than that of the front element.
  • This projectile is essentially constituted by the combination of at least two shell elements I and 2 disposed in tandem-like fashion and at least one of which includes an incendiary charge, the front element I including, anyway, an explosive charge 3 capable of ensuring its destruction when the projectile has passed through a first wall, whereby the rear element 2, preferably made like an armour piercing shell, can then, like an independent projectile, strike a second wall located behind the preceding one, the charge in said rear element being ignited only in response to this second impact.
  • the characteristics (shape, mass, constitutive metal, etc.) that determine the respective perforating powers of the two shell elements for a given muzzle velocity, are chosen at will, but preferably these perforating powers should be greater for the rear element than for the front one, whereby the projectile can pass through walls of increasing resistances, for instance, in the case of a double projectile, first through a mere metal sheet, then through a relatively thick armour plate located behind said metal sheet.
  • front element l is constituted by an ogive-shaped cap secured on the front part of the rear element 2, said cap, which is preferably made of steel, carrying at the front a nose 4 in which is housed a priming pin 5 capable of producing, or at least of facilitating, upon the first impact, the firing of a relay charge 6 which then ensures ignition of the explosive charge 3 and of the incendiary charge 1, preferably located behind the preceding one.
  • the rear element preferably of hard metaLsuch as hardened steel, has a thick point at the front and, behind this point, a shoulder 8 against which the rear edge of cap I can be applied, a cavity being provided in the body of said core to contain the incendiary charge 9, and also possibly an explosive charge, said recess being temporarily kept closed by a rear plug [0.
  • An armor piercing and incendiary shell primarily for use against military targets or the like having a relatively low resistant first wall or the like spaced from a second wall or the like having resistance greater than the first wall, said walls or the like being located in independent spaced relationship with each other, said shell comprising at least two'elements assembled one behind the other in tandem-like fashion with the rear portion of the front shell element contiguous with the front portion of the rear shell element, a charge in each of said elements, said charge being explosive in the front shell element and partly incendiary in at least one of said two elements, means for firing said explosive charge in the front shell element in response to impact of said shell on said first wall, said rear shell element being of an armor-piercing nature and of a higher armor-piercing power than said front shell element, said rear shell element and its charge being sufficiently insensitive to shock so as tosurvive the first impact of said shell upon said first wall, said rear shell element being constituted to survive the explosion occurring upon the first impact and to preclude sympathetic detonation under
