Definitions

  • a rotation-stabilized practice floor is known. This has the property of corresponding to the properties of a combat missile up to a certain target distance. After that there is a shortened flight distance. This is achieved by means of longitudinal ribs which are arranged on the circumference of the practice floor.
  • a sabot projectile is known from DE-OS 36 00469.
  • the projectile is arranged in a sabot and held radially within the sabot by several separate support levers.
  • the object of the invention is to propose a sabot projectile that is suitable for simulating imported, sub-caliber balancing projectiles.
  • a projectile 1 of a sabot projectile 50 is mounted in a sabot 13, namely in a bore 2 of a sabot 3 made of aluminum and axially fixed by a securing ring 4.
  • the locking ring 4 engages in grooves 5 and 6.
  • the floor 1 has a caliber of 15 mm and is made of tungsten carbide. It is intended for a plug-in barrel device for a 120 mm tank cannon. A gas hole, grooves for the attachment of a propellant charge cartridge and a guide band are designated 22 to 24.
  • the retaining ring 32 lies within the contour of the segments 7 and the sabot 3 and is pressed against the acceleration direction into the stage 31 during the projectile acceleration in the stage 31.
  • the depth 33 of the groove 30 up to the stop surface 34 corresponds to 3 times the thickness of the retaining ring 32.
  • the length 35 is greater than the width of the retaining ring 32.
  • the securing ring 4 When the sabot projectile 50 emerges from a plug-in treadmill 40, the securing ring 4 has already unlocked the projectile 1, the retaining ring 32 has slipped from the step 31 and the dynamic pressure in the annular space 26 has spread the segments 7 until the retaining ring 32 is deformed.
  • the segments 7 have defined bending zones up to the abutment of the abutment surfaces 11 and 12 due to the hinges 14.
  • the retaining ring 32 thus intercepts and limits the outwardly bending segments 7 to protect a protective tube 41 which extends to the mouth of the cannon (not shown) Spread the segments 7 in such a way that, on the one hand, there is a substantial enlargement of the end face of the sabot 13, on the other hand, the segments 7 cannot break off.
  • the stop surfaces 11 and 12 provide further support.
  • the sabot 13 is designed so that no parts can fly sideways when it emerges from the plug-in treadmill 40. This prevents damage to the protective tube 41 and thus also damage to the weapon barrel and faults in the projectile when the protective tube lying in the weapon barrel flies through
  • the projectile 1 is spin-stabilized and has the best possible flight path equality with a combat projectile up to a certain target distance. Due to the longitudinal ribs 21 of the projectile 1, as already described in the German patent 32 01 629, a shortened trajectory is ensured after the target distance has been exceeded.
  • sabot 13 consisting of a few parts with the locking ring 4, the guide band 24 and the retaining ring 32.
  • the specified calibers and materials can be easily adapted to the corresponding requirements.
  • the idea of the invention also includes using the projectile consisting of a heavy metal as combat ammunition.
