Definitions

  • the invention relates to a projectile, in particular a training projectile, which can be fired from a weapons system with Feuerleitrechner.
  • Such a training ammunition is for example from the DE 100 14 513 A1 known.
  • a provided with a Schlitzkegelleitwerk training ammunition is among others the US 5,498,160 removable.
  • a Lochkegelleitmaschine describes the DE 90 12 031 U1 ,
  • the invention provides the task of specifying a way how the adaptation of an existing training ammunition can be realized with a bowling and a previously uncoordinated, but existing Feuerleitrechner also from the point of view of economy.
  • the invention is based on the basic idea not to change the Feuerleitrechner as before, but to adapt the existing training ammunition to this.
  • the complex interplay between the temperature behavior of the ammunition from -15 ° C to 35 ° C and the trajectory curve must be taken into account.
  • the adaptation happens in that the training ammunition with another propellant charge powder provided at least but the diameter of the cone angle is increased at the same length of the tail.
  • this achieves a complex adaptation to the temperature and trajectory behavior and only a trajectory error (at - 15 ° C to + 35 ° C) is less than 0.1 is possible.
  • an I-propellant charge powder is used instead of a simple propellant charge powder.
  • a projectile 1 here a training ammunition, according to the prior art, consisting of a conical structure 2 with slots 3 and other, for the explanation not to be considered details.
  • the existing tail 2 which for example has a cone angle of about 78 mm, is replaced by a, a larger cone angle, for example, 88 to 94 mm, owning tail 2.1 (Fig.1a). This is done for example by screwing on the cylindrical part 4 of the ammunition. 1
