Definitions

  • the invention relates to a full-caliber training projectile according to the preamble of claim 1.
  • a bullet of the same type is known from DE-A-2846998.
  • a bolt of circular cross section projects over a smooth rear boundary surface. With its free end, the bolt is received in a central axial blind hole of an essentially full-caliber ballast body which is adapted to it.
  • the length of the bolt is greater than the depth of the blind hole.
  • the bolt has a larger outer diameter in a front area than in the area of the free end.
  • the inner diameter of the blind hole in its front area is adapted to the larger outer diameter.
  • the inside diameter of the blind hole is adapted to the smaller outside diameter of the bolt.
  • a rubber-elastic spring element is arranged between the rear annular surface of the front part and a front boundary surface of the ballast body which surrounds the mouth of the blind hole. It is designed like a thick-walled tube, surrounds the bolt closely and is supported against the two aforementioned boundary surfaces on the front and back.
  • the spring element is weakly sub-calibrated; consequently, a circumferential recess extends between the two boundary surfaces in the initial state of the projectile.
  • the ballast body has a guide ring in its peripheral region.
  • the final acceleration of the ballast body compresses the rubber-elastic spring element without the arrangement in the said area becoming over-calibrated. As soon as the arrangement has left the weapon barrel and is no longer under the direct influence of the propellant gases, the energy stored in the spring element is released. As a result, the ballast body is moved against the direction of flight on the bolt towards its free end, the axially aligned guide is lifted, and the ballast body separates from the bolt of the front part.
  • FR-A-2286364 a full-caliber spin-stabilized training projectile with a shorter range is known, which should initially behave like a sharp reference projectile.
  • the projectile in its front area or in the ogive has a plurality of recesses arranged next to one another and running in the longitudinal direction of the projectile, which increase the drag coefficient and reduce swirl combined with destabilization from the time of the launch.
  • this also disadvantageously results in a deviation from the trajectory of the reference projectile, which is initially only slight but increases continuously with increasing flight distance, even immediately after leaving the weapon barrel muzzle.
  • FR-A-2527764 Another range-limited practice floor is known from FR-A-2527764.
  • This artillery projectile is hollow and provided with means (e.g. asymmetrical construction) for generating unbalances.
  • the projectile body fired with swirl is excited to oscillate too much (possibly up to the transverse position of the projectile) with increasing air resistance and falls to the ground after a short flight distance.
  • This projectile cannot be compared with a reference projectile or a sharp combat projectile, not even in the first phase of flight.
  • the invention has for its object to provide a training projectile of the type mentioned, which is easy to manufacture, behaves essentially like a sharp reference projectile on a flight path assigned to a predefinable shot distance, remains in one piece on its entire trajectory to be considered with unchanged mass and there is good reproducibility of the results with a good comparability in relation to the conditions when firing with sharp reference ammunition.
  • a practice projectile 10.1 extends with a tip 12, a rear surface 14 and a peripheral surface 16 along a central longitudinal axis A and has an annular recess 18.1.
  • the projectile 10.1 is of full caliber design with a caliber d.
  • the depth t of the recess 18.1 corresponds approximately to a fifth to a quarter of the caliber d.
  • the practice floor 10.1 is intended for barrel weapons with drawn barrel and a caliber of, for example, 155 mm. A guide ring has not been shown.
  • the exercise floor 10.2 according to FIG. 2 essentially differs from the exercise floor 10.1 described in connection with FIG. 1 by a second recess 18.2 in the rear area of the exercise floor in question.
  • both recesses 18.1 and 18.2 are of the same depth; however, the widths b i and b 2 differ from one another without the specified limits for the numerical value of the ratio t / d being exceeded or undershot.
  • a region of the first part of the trajectory of the training projectile according to the invention which can be predetermined in terms of its length, can be adapted in a reliable manner to the corresponding trajectory of a relevant reference projectile in such a way that the ones for the training projectile are valid for the reference projectile Firing boards can be used.
  • practice shooting can be carried out realistically, even with strict adherence to the safety regulations aimed at the permissible range and dispersion.
  • the practice floor which is easy to manufacture, remains in one piece after firing. Despite its similarity to the reference floor, the training floor can be distinguished from the reference floor when loading in the light by eye and by key in the dark.
  • a changeable exercise floor was not shown. However, this is understood to be a structure made up of the elements of a modular structure. In this connection, reference is made to DE-C-2609590. The relief of logistics is striking.
