Definitions

  • the housing is of synthetic material, preferably a glass fiber reinforced polyester with the glass fibers in said cylindrical portion oriented in the longitudinal direction of the housing and with the glass fibers in the bottom crossing each other.
  • the present invention relates to practice ammunition for firing from rifled barrels, the disintegration projectile of which comprises a mantle forming a container of synthetic material and also comprises a core of heavy powder, preferably iron powder compressed to a body.
  • a projectile is provided with a relatively thick container wall and, in particular, with a strong bottom in order to withstand high stresses, which bottom alone resists the propulsion charge necessary for a quick firing sequence and automatic feeding, it is difiicult to disintegrate these parts into corresponding small particles or, expressed differently, to eliminate any piercing force over a short distance.
  • FIG. 1 represents a longitudinal section through a practice disintegrating projectile with a mantle according to the present invention.
  • FIGS. 2 and 3 diagrammatically illustrate a bottom view of the mantle according to FIG. 1 in a pre-manufacturing stage.
  • the projectile container or mantle according to the present invention is characterized primarily in that it consists of glass fiber reinforced synthetic material, especially a polyester. Furthermore, the glass fiber material is length oriented on the cylindrical wall and the glass fibers at the bottom may be placed so as to cross each other.
  • the projectile container or mantle comprises an envelope or casing 1 of synthetic material, as for instance a polyester, which has the shape of a projectile with a blunted nose 2 and an obturator head 3, as well as a reinforced bottom 4 and a compressed powder disintegration body 5.
  • Embedded in the said synthetic material which is preferably a polyester are glass fiber inserts 6, 7 which are poured or injected into the synthetic material and are longitudinally oriented in the mantle wall 8.
  • the said glass fiber inserts extend from the bottom 4 to the tip 2, whereas in the bottom 4 itself they are transversely oriented and are crosswise or at a different angle arranged in layers.
  • the mantle 8 of the illustrated projectile 1 is in view of the glass fiber inserts 6, 7; 9, 10, 11 stable in longitudinal direction and is also non-sensitive against shocks acting radially from the outside.
  • the bottom 4 has a great strength so that it will be able to withstand the propelling charge pressure required for a fast firing sequence.
  • the practice ammunition provided with such a projectile is suitable for roughest handling and thus meets the first requirement above referred to.
  • a projectile shaped housing of synthetic material reinforced by glass fibers which includes: a projectile shaped housing of synthetic material reinforced by glass fibers, a core of powder within said housing, said housing having a relatively long and narrow cylindrical portion and a blunted nose portion and being closed by a bottom of synthetic material reinforced by glass fibers crossing each other, the glass fibers in said cylindrical portion of said housing being oriented in the longitudinal direction of said cylindrical portion.
