Definitions

  • the invention relates to a projectile, in particular in the medium caliber range, with a marking charge and a ground lighters.
  • Explosive grenades generally contain secondary explosives that are initiated by a separate detonator. This feature makes the projectiles expensive and increases the risk of unexploded ordnance as well as an improper implementation with the corresponding consequences. In addition, explosive grenades in practice areas are undesirable.
  • Projectiles with pyrophoric or pyrotechnic active charges that are discharged, nebulized and initiated purely by the target impact can in part not reliably mark the target or impact, since the effect is obscured, e.g. covered by sand or extinguished by it.
  • Color markings such as from the EP 1 183 494 B1 known, are only partially visible.
  • the DE 197 58 459 A1 shows a warhead with means for targeting.
  • the marking charge is a pyrotechnic charge that generates infrared radiation.
  • the marker bullet is expelled backward from the warhead by triggering a first pyrotechnic charge.
  • the disadvantage is that the triggering of the marking is effected by a detonating chain.
  • the invention has as its object to avoid this disadvantage.
  • the invention is based on the idea to show a projectile with a ground lighters and a Markierladung, which can be dispensed with a detonating chain with explosives.
  • the projectile comprises a pyrotechnic marking charge, which is initiated by a priming chain in the ground igniter. Due to the resulting gases and the pressure, the bottom lighter is pushed backwards out of the projectile. The unfolding marking charge (the reaction) also exits backward out of the projectile and creates an optimal marking point, which can also be seen from the air.
  • the marking load marks the target reliably on soft as well as on hard, on wet and on sandy soils or targets and also with flat landing angles.
  • the pilot or shooter is thereby enabled to correct the target point based on the impact lightning.
  • the marking charge preferably comprises a charge in the IR as well as in the visible range, so that the target marking effect can be recognized both in the IR range and in the range visible to the eye. Other possibilities are not excluded.
  • the pyrotechnic marking charge is located in the projectile body of the projectile. If the projectile hits the target, a ballistic dome of the projectile is mechanically destroyed by the target impact. The rest of the projectile is now delayed by the target material. Due to the delay, the ignition chain initiates the pyrotechnic marking charge in the projectile body. A resulting pressure between the projectile body and the bottom lighter leads to the ejection of the ground starter. The pyrotechnic reaction works against the weft direction and marks reliable, regardless of the ground condition of the impact point (target) in the form of a lightning bolt.
  • the ignition chain is preferably mechanical.
  • a firing pin may preferably move axially in the bottom launcher. By this movement, for example, a primer capsule is then initiated.
  • the movement of the ignition pin is made possible by the fact that a securing element releases the firing pin during firing, preferably through the projectile twist, thus enabling the necessary degrees of freedom for the firing pin.
  • a projectile is proposed, in particular in the mid-caliber range, with a projectile body and a marking charge, the marking landing being a pyrotechnic marking charge.
  • the projectile has a bottom lighter, in which a primer chain is arranged. After initiation of the pyrotechnic marking charge by the ignition chain of the bottom lighter is ejected from the rear side of the projectile body, so that an application of the marking charge takes place at the projectile tail against the weft direction.
  • the proposed pyrotechnic marking charge is characterized by a composition which acts in the IR range as well as in the visually visible range, but is not limited to these.
  • the reliability compared to other projectiles with explosive and ignition chain can be significantly increased. Since the initiation of the pyrotechnic marking charge is always realized via the ignition chain, the size and intensity of the pyrotechnic target marking are independent of the impact velocity and the target material and thus constant. The principle is also operational at least up to an angle of 77 ° (NATO).
  • the projectile 10 has a base lighter 4, which is also arranged in the projectile body 3 and this preferably ends on the bottom side.
  • the bottom lighter 4 comprises a priming chain 5.
  • the igniting chain 5 is constructed mechanically or pyro-mechanically.
  • the igniter chain 5 can be formed by a AnzündX and a Anzündkapsel.
  • the primer chain can in principle also be constructed electrically, electronically or electro-mechanically.
  • the igniting chain 5 can be secured by a securing element 7 within the ground starter 4.
  • the projectile has a ballistic hood 8.
  • the marking charge 2 comprises a pyrotechnic composition which is effective in the IR range and / or in the visually visible range.
  • the operation is as follows:
  • the securing element 7 preferably secures the first element of the igniter chain 5 in the bottom lighter 4 and secures it against improper conversion / release within the ground starter 4 during, for example, storage, transport, handling or delivery of the ammunition in the weapon.
  • the igniting chain 5 is released by the securing element 7.
  • the ballistic hood 8 is destroyed purely mechanically by the target impact.
  • the target material e.g., sand, wet sand, concrete
  • the implementation / triggering of the igniter chain 5 ignites the pyrotechnic marking charge 2 in the projectile body 3.
  • a resulting pressure between the projectile body 3 and the bottom igniter 4 presses the bottom igniter 4 on the rear side 9 out of the projectile 10.
  • the pyrotechnic reaction (the marking charge 2) also acts counter to the weft direction and marks the target point or the target impact.
