Definitions

  • the invention relates to a projectile with programmable timer, which at least has a data reception coil and a power supply, and with an active mass, which is emitted after a programmed igniter setting time.
  • Such a projectile consists of a projectile body to which a ballistic hood is attached at the front and an igniter housing at the rear.
  • a programmable time igniter is provided in the igniter housing and consists of a data reception coil, a power supply with shock generator, an electronic time igniter module, an igniter, a detonator and an exhaust charge.
  • an effective space is provided in the projectile body, in which an active mass in the form of sub-projectiles is arranged to prevent rotation.
  • a retaining screw holds the active mass in the axial direction and connects the projectile body with the hood.
  • the active mass is designed as a projectile core, that of a sabot jacket and a sabot rear is held.
  • the data receiving coil and the power supply are arranged in the sabot tail while the remaining parts of the programmable Timers are built into the core of the projectile.
  • In the sabot coat and in The sabot tail is provided with predetermined breaking points, so that after the Storey the sabot jacket and the sabot tail with the data receiving coil and the power supply are separated and only the floor core with the remaining parts of the programmable timer continue to fly alone.
  • 1 denotes a sabot jacket and 2 a sabot tail, which is firmly connected to the sabot jacket 1 .
  • a projectile core 3 is held, which is formed from an active mass 4 .
  • the active mass 4 consists of lined-up metallic, disc-shaped bodies 5 which have threaded attachments 6 , by means of which they are screwed together.
  • holes 7 are provided, which are distributed on a concentric to the central axis of the body 5 and the projectile part circle evenly. A pre-fragmentation of the body 5 is achieved with the bores 7 , as a result of which the fragment size can be influenced.
  • a programmable timer 8 is built into the projectile core 3 and consists of an electronic timer module 9 , an electric primer 10 , a detonator 11 and a detonating core 12 .
  • a data reception coil 13, which also belongs to the time fuse 8, and an energy supply in the form of a shock generator 14 are arranged in the sabot rear 2 . With 15 a circumferential groove is designated, which is used to attach a protective hood, not shown, to the sabot jacket 1 .
  • an active mass 21 arranged in a projectile body 20 consists of a large number of heavy metal sub-projectiles 22, for example having a cylindrical shape.
  • the subprojectiles 22 are combined to form subprojectile columns 23 which run parallel in the longitudinal direction of the projectile and which, as not shown further, are held in the projectile body 20 in a rotationally secure manner and fixed in the longitudinal direction.
  • a projectile tip connected to the projectile body is designated.
  • 28 denotes an ejection charge which is used instead of the detonating core 12 of the embodiment according to FIGS. 1, 2 and 2a .
