Definitions

  • the invention relates to a training projectile with the features of the preamble of claim 1.
  • Such a floor is e.g. B. from DE-PS 734 429 known.
  • the projectile body is made up of several parts, such as segments, sheets and disks, which are held together by spring-loaded bolts or balls as a holding device.
  • the individual parts of the projectile are released only after a certain flight distance, after the air resistance has decreased and then a securing of the holding device can be released by centrifugal force or by springs.
  • the construction of such a floor is very complicated and expensive.
  • the individually flying storey parts are unstable and unpredictable and therefore pose a danger to the environment.
  • the object of the invention is to create a much simpler training ammunition for artillery, with the same charges and the same range of increase how live ammunition can be fired on short firing ranges.
  • the projectile After a brief, unstable transition phase from the spin-stabilized state, the projectile is said to get into a resistance-stabilized, predictable state.
  • the projectile should be able to be used as a pure training projectile, it being only a matter of trying out the weapon itself or the shooting process without hitting requirements, the projectile being intended to fly only very briefly.
  • the floor is equipped with a basement that flies to the destination with a shorter range, with which meeting requirements can also be simulated.
  • the sleeve 1 to 3 consists of the sleeve 1 firmly connected to the floor 3 and here, for example, of the front part formed from two identical sections 2.
  • the sleeve has a guide ring 1c at the rear and may have a guide bead 1b at the front.
  • the sections 2 have a groove 2a in the front area for receiving a ring as a holding device.
  • the rear stepped end 2b of the sections lies on the front stepped part 1a of the sleeve 1.
  • the sections have elongated holes 2c into which bolts 4, which are fastened in the sleeve, engage.
  • the sections 2 of the front part tapering towards a tip, possibly as an ogive, have cylindrical sections 2d with a guide bead 2e.
  • the ring in the groove 2a tears immediately after leaving the mouth as a result of the centrifugal force and the sections open. As long as the projectile is still in the tube, opening is not possible due to the cylindrical sections 2d or the guide beads 2e. After spreading, the free-flying shell formed from the front part and sleeve becomes unstable.
  • the mutually facing end faces 2f of the sections have bevelled surfaces 2g at the rear, which abut one another when the sections are expanded and, depending on the desired helix angle, define a predetermined spread angle of the sections.
  • the sections z. B. be held by a compression spring 8.
  • the range of the envelope can be determined by the opening angle of the sections, which results from the respective length of the elongated holes (2c) and the angle of the bevelled surfaces 2g.
  • the angle must be designed in such a way that the shell can be brought as a stable projectile at a defined distance from the gun, without being endangered by flying parts.
  • the predetermined spreading angle of the sections is maintained by the fixing means 8 or 9 even with decreasing centrifugal force, so that a calculable trajectory results.
  • a basement 6 is supported on the floor 3 with an empennage, here a conical tail 6a.
  • the basement is encompassed by the sections 2, which are held together by a ring in a groove 2a.
  • 2d a section of the sections 2 which is to be cylindrical.
  • 2e denotes a section of the sections, which should be exactly the same caliber as the bead, while the cylindrical section 2d in front of it is sub-calibrated by fractions of a millimeter.
  • the basement can be provided with at least one projection and a groove or with an external thread in the front area and the sections 2 there with a groove and projection or with an internal thread.
  • the tip 6b of the basement can be designed as a detonator. Behind it there can be a Deut charge 5 and in the rear part a light set 7 for a light trail can be accommodated.
  • the basement is released after the sections 2 have opened when firing.
  • the shell is slowed down due to the high air resistance of the spread sections 2 start and releases the basement, which flies to the target as a stabilized training floor with a predictable shortened range.
  • the approach to the destination can be made visible through the tracer and the Deut charge can indicate the point of impact of the basement.
