Definitions

  • the invention deals with a so-called self-consumable projectile or ammunition, also with a practice projectile or practice ammunition, which is effective up to a predefined effective distance, but which, on the other hand, quickly reduces the speed when this distance is exceeded.
  • the US 9,121,679 B1 discloses a bullet with a range regulation.
  • the projectile has a reactive material in addition to a pyrotechnic primer.
  • the primer is located in an interior space and extends forwardly into the interior space from the rear end of the projectile.
  • the reactive material completely surrounds the pyrotechnic material inside.
  • a small opening may be formed at the rear of the bullet and covered with a membrane.
  • the reactive material has the task of making the projectile unstable, disrupting the flight behavior of the projectile. A possible non-lethality of the projectile is not provided for here.
  • the invention takes on the task of demonstrating ammunition that maintains the effect (energy) up to a defined distance range and then dissipates the energy very quickly. A predetermined distance should not be exceeded, so that there is no danger in the hinterland.
  • the invention is based on the idea of specifying ammunition or a projectile which, at a so-called main combat range, is not subject to any external ballistic interference, but which can then reduce the speed significantly more quickly if the target has not been hit.
  • these must have properties that are as identical as possible to the corresponding combat ammunition within the training main combat distance, but then be able to reduce the speed much more quickly.
  • this reduction in velocity takes place in that the projectile consumes itself after a certain time or after a certain flight distance, i.e. it reduces, minimizes its weight and thus eliminates itself.
  • the weight reduction and thus the elimination takes place in that at least one pyrotechnic charge is integrated in the projectile, which determines the weight or the mass of the projectile and is only ignited when the effective distance is exceeded.
  • the bullet loses weight or mass over the flight time or flight distance.
  • the projectile is adjusted to the desired effective distance via the firing rate of its pyrotechnic charge(s).
  • the projectile consists of a projectile jacket, for example made of metal or a plastic.
  • the shell is filled with at least one pyrotechnic charge.
  • Jacket and pyrotechnic charge together form the projectile, ie the firing and effective weight the initial mass of the projectile.
  • a propellant charge not shown in detail, of an ammunition, also not shown in detail, ignites the pyrotechnic charge when it is fired.
  • the pyrotechnic charge then burns off at a defined speed during the flight phase or flight time. This defined burning can be adjusted by the composition of the pyrotechnic mixture of the set.
  • a setting is also possible via the volume selection of the sets. Combinations of known possibilities are known to the person skilled in the art and are available here.
  • the firing speed is to be adjusted in such a way that the speed and projectile mass still have the required energy at the defined effective distance and ensure functionality.
  • Two or more sets are to be provided for a gradual burn-up. Different pyrotechnic charges are then preferably also involved.
  • delay sections can also be provided here.
  • the lightweight envelope remains, so the residual energy or residual velocity dissipates faster.
  • the casing can also burn when the pyrotechnic charge burns up, or afterwards, so that the projectile is completely consumed.
  • Combustible sleeve material is, for example, from the EP 1 123 482 B1 famous.
  • Projectiles of this type can preferably be used at firing angles >30° in order to ensure non-lethality. It is important that by the time the projectile hits the ground, the pyrotechnic charge has burned off so that only the light projectile casings with little residual energy fall to the ground, if at all. These projectiles are particularly suitable for non-lethal combating of air targets or light air targets such as drones.
  • This constructive measure or measures ensures that the ammunition has identical external ballistic properties (trajectory) for the effective range or the effective distance as the corresponding combat ammunition, but a maximum overall range is not exceeded. This increases security in general.
  • the invention will be explained in more detail using an exemplary embodiment with a drawing.
  • the only figure shows a sketch of a projectile 1 with a projectile casing or projectile casing 2 and, in this exemplary embodiment, two pyrotechnic charges 3, 4 integrated into the projectile casing 2. Both sets 3, 4 enable gradual combustion.
  • the projectile 1 or the projectile casing 2 has an open projectile base 5 which is closed with a destructible membrane 6 until it is fired.
  • a membrane 7 can be inserted between the two pyrotechnic charges 3, 4.
  • the pyrotechnic charge 3 is ignited when the projectile 1 is fired from a weapon barrel or weapon barrel, which is not shown in detail. This lighting can be done directly.
  • the pyrotechnic charge 3 is dimensioned (volume, mixture, etc.) such that it only ignites the other pyrotechnic charge 4 when an effective distance for the projectile 1 is exceeded.
  • the pyrotechnic charge 3 can also be ignited with a delay.
  • Delay elements and their setting show, for example, the DE 10 2013 013 705 A1 , the DE 10 2012 014 1450 A1 or DE 10 2012 014 149 B3 , which is hereby incorporated by reference.
  • the projectile 1 loses mass or weight. The mass tends towards zero. This ensures a low residual mass of the projectile 1 outside the effective range. Safety is increased and a non-lethal effect of the remaining projectile is achieved, especially outside the effective range.
