Definitions

  • the invention relates to a sub-caliber ammunition, in particular for aircraft cannons, with a sub-caliber projectile core and a sabot.
  • a sabot designed as a sabot is connected to the sub-caliber projectile core by means of a spring ring provided as a centrifugal force lock.
  • the spring ring expands under the action of the swirl of the projectile, so that the projectile core leaves the sabot.
  • the sabot has a high flow resistance, so that it remains behind the core of the projectile. There is a risk that both the sabot and plastic parts of the hood will hit the shooting aircraft and damage it.
  • DE-OS 35 08 053 describes a sub-caliber floor with a segmented sabot. After the launch, the sabot is broken down into its segments due to its high flow resistance, so that the core of the projectile becomes free. If such a projectile is fired from an aircraft, there is a risk that the aircraft will fly into the sabot segments.
  • the object of the invention is to propose ammunition of the type mentioned in the introduction, in which the sabot separating from the projectile core does not lead to any dangers on the firing side.
  • the above object is achieved in the case of ammunition of the type mentioned at the outset in that the sabot is designed as a secondary projectile which is stable in itself and which has a predictable trajectory.
  • the sabot flies like a bullet after being separated from the core. On the one hand, this ensures that a shooting aircraft cannot hit the sabot. On the other hand, the effect of the ammunition is increased, since in addition to the core of the projectile, the sabot can also have a projectile effect. A particular advantage is that the trajectory of the sabot can be calculated. Furthermore, higher impact energies and shorter target times mean higher target effects are achieved due to the sub-caliber.
  • the sabot as a secondary storey can be designed in the embodiment of the invention as a tubular storey in which the projectile body is arranged coaxially.
  • the sabot can be a projectile core on which an effective tubular projectile is arranged coaxially.
  • the centrifugal force safety device is designed as a seal between the tubular projectile and the projectile core. This eliminates the need for additional measures with which the projectile core guided in the tube storey is to be sealed with respect to this, in order to avoid an undesired passage of propellant gas between the tube storey and the storey core.
  • FIG. 1 is a sub-caliber ammunition with a tube storey 15 trained sabot provided in which a projectile core 16 is inserted.
  • the tube storey 15 also has a ballistically shaped tip 17 as does the projectile core 16 with the tip 18.
  • the tube projectile is also effective with this combination.
  • the sabot 19 is designed as a projectile core with a base body 20 and a ballistic tip 21 formed thereon.
  • a guide band 22 is provided on the lateral surface of the base body 20 in a corresponding annular groove.
  • a tube storey 1 has a guide band 2.
  • the front end 3 of the tubular storey 1 is tapered by a bevel 4.
  • a sub-caliber projectile core 6 is inserted flush.
  • a spring ring 7 is provided for connecting the projectile core 6 to the tubular projectile 1. This lies partly in an annular groove 8 of the projectile core 6 and partly in an annular groove 9 of the tubular storey 1.
  • the spring ring 7 also seals an existing gap between the outer circumference of the storey core 6 and the inner circumference of the tubular storey 1.
  • the projectile core 6, with its ogive-shaped head part 10, projects beyond the front end 3 of the tubular storey 1.
  • the reverse construction is also conceivable here.
  • a small free space 11 is provided between the head part 10 and the front end 3.
  • a rear-side, open end 12 of the tubular storey 1 projects beyond a floor 13 of the storey core 6, so that there is a space 14.
  • the spring ring 7 When leaving the gun barrel, the spring ring 7 widens as a result of the swirl, so that the projectile core 6 is axially free from the tubular projectile 1.
  • the projectile core 6 and the tubular projectile 1 leave due to their different air resistances and their different inertias.
  • the tube storey 1 also shows a stable, swirl-stabilized flight behavior with a low Cd value in internal currents, so that it surely quickly moves away from the weapon barrel or the shooting aircraft.
  • the tubular storey 1 can be designed such that it assumes essentially the same trajectory as the storey core 6. The tubular storey 1 then becomes effective in the target of the storey core 6.
  • the projectile core 6 can be designed as a balancing projectile, as a fragmentary projectile or as a detonator projectile.
