Definitions

  • the invention relates to a detonating fire grenade with a projectile body and a ballistic hood arranged in front of the projectile body, with an explosive charge arranged inside the projectile body, with a fire charge arranged before the explosive charge and with a highly sensitive base detonator arranged behind the explosive charge.
  • a pyrotechnic mass is arranged in front of the projectile body, which is enclosed by a ballistic hood. Behind the projectile body is another pyrotechnic mass, which is also referred to as explosive fire mass, which only takes effect after the target armor has penetrated. In the rear of the projectile behind the blasting compound there is a highly sensitive but delayed detonator which, after the armor penetration core has penetrated the target, tears open the armor piercing core and distributes it together with the blasting material in the target.
  • the task that is to be solved with this well-known armored fire projectile is to design the projectile so that on the one hand it penetrates heavily armored targets and only becomes fully effective behind the armor, but on the other hand it also responds reliably if only weak structural parts are hit.
  • the explosive fire mass provided behind the projectile body should be brought to full effect after penetration.
  • the task that is to be solved with the explosive fire grenade according to the invention is to increase the fire effect of the fire charge located in the interior of the projectile body and, if possible, also to eject the fire charge from the side.
  • this object is achieved in that the explosive charge has an exclusively conical tip at its front end; and that the incendiary charge has an exclusively funnel-shaped recess into which the conical tip of the explosive charge protrudes.
  • the explosive device grenade 10 has a projectile body 11 which is provided with a tip 12 for penetrating a target and which has a cavity 13 for receiving a fire charge 14 and a two-part explosive charge 15, 16.
  • the fire charge 14 has a funnel-shaped recess 17, into which a conical tip 18 of the first explosive charge 15 projects.
  • the first explosive charge 15 has a bowl-shaped recess 19, into which a curved projection 20 of the second explosive charge protrudes.
  • the explosive device grenade 10 contains five grams of fire mass, in particular zircon for the fire charge 14, as well as 7.5 grams of Hexal P15 (a brand name) for the first explosive charge 15 and again 7.5 grams of Hexal P15 for the second explosive charge 16. Because of the Using a conical press ram, the fire charge 14 can be pressed into the cavity 13 of the penetration core 11 in such a way that said funnel-shaped recess 17 is created. The first explosive charge 15 is then partially pressed into the interior of the fire charge 14. By using a similar press ram, the first explosive charge 15 can be pressed into the cavity 13 of the projectile body 11 in such a way that the shell-shaped recess 19 is created.
  • the second explosive charge 16 is then partially pressed into the interior of the first explosive charge 15.
  • the second explosive charge can be pressed into the hollow space 13 of the projectile body 11 in such a way that a recess is created for receiving the base igniter (not shown).
  • the tip 12 of the projectile body 11 is surrounded by a ballistic hood 21.
  • This ballistic hood 21 has a cylindrical Holraum 22 in which a further fire charge, not shown, can be used.
  • the fire effect is increased by the combination of two explosive charges 15 and 16 with a fire charge 14;
  • the particles of the fire mass are sprayed in a larger area by the explosive charge and the flames therefore have a longer service life.
