Definitions

  • the invention relates to an incendiary device for a wing-stabilized balancing projectile which can be arranged in the rear-side region of the projectile and penetrates into the target as a separate unit when hitting a target behind the penetrator of the balancing projectile.
  • Wing stabilized balancing projectiles in which incendiary devices are arranged in the rear-side region of the projectile are, for example, in the German patent applications DE 199 48 708.1 and DE 199 48 710.3 described.
  • the commonly used tracer set is replaced by the set of fire, in order to achieve that the balancing projectile when striking semi-hard targets (eg provided with a relatively thin armor infantry fighting vehicles) unfolds a considerable fire effect.
  • semi-hard targets eg provided with a relatively thin armor infantry fighting vehicles
  • the penetrator of the balancing missile would fly through the semi-hard target and exert on this no significant destructive effect, but only produce a maximum projectile diameter corresponding hole in the armor.
  • incendiary made of a metal sponge and an organic binder known.
  • a metal sponge of zirconium or hafnium and used as a binder polytetrafluoroethylene.
  • these known incendiary devices can not be optimally initiated by shock waves, especially not when only relatively small quantities of the corresponding incendiary rate are used, as is the case with the incendiary beacon-replacing incendiary devices.
  • the invention has for its object to provide incendiary devices for wing stabilized balancing projectiles, which cause a large destructive effect within a target despite a relatively small volume and a low mass and are ignited safely in the event of impact with a target by the resulting shockwaves.
  • the invention is based on the idea of using a titanium sponge as an incendiary charge, wherein an epoxy or polyester resin is used as the binder. Since the incendiary contains no oxygen carrier, it is relatively insensitive.
  • the titanium sponge particles are then heated up to the ignition temperature and continue to burn intensively when the particles become free with the atmospheric oxygen.
  • the relatively brittle titanium sponge is much better suited as a fuel charge than ductile materials, such as zirconium, magnesium or aluminum powder due to its low ductility.
  • the inventive incendiary also cause a setting on fire flame retardant oils (such as diesel or hydraulic oil).
  • incendiary devices behave in the normal state as an inert material and can be brought to inflammation only with a very strong blow. It is therefore possible even if the target is missing a safe handling of the projectile, if the fire sentence is not damaged.
  • the fire set consists of a mixture of 85 to 96% by weight titanium sponge and 4 to 15% by weight of the epoxy or polyester resin and has a density of between 1.7 and 2.8 g / cm 3 is located.
  • the grain size of the boron powder should preferably be ⁇ 10 microns.
  • the fire rate therefore consists of a mixture of 65 to 86 wt .-% titanium sponge, 4 to 15 wt .-% of an epoxy or polyester resin and 10 to 20 wt .-% boron powder, the density of the fire rate turn between 1.7 and 2.8 g / cm 3 .
  • the particle size range of the titanium sponge such that 30% of the titanium sponge particles have a particle size greater than 450 microns and 70% have a particle size less than 450 microns.
  • 1 designates a large-caliber wing-stabilized balancing projectile, as it is fired, for example, from tank cannons.
  • the balancing projectile 1 comprises a penetrator 2 and a stabilizer 3 attached to the penetrator. This consists essentially of a sleeve-shaped stabilizer support 4 with stabilizing wings 5 arranged on the outside and a longitudinal axis 6 of the balancing projectile 1 extending on the side facing the penetrator 2 through this closed recess. 7
  • the rear-side region 8 of the penetrator 2 extends into a second subregion 9 of the recess 7 and is connected to the tail carrier 4, e.g. connected by a threaded connection 10 non-positively.
  • first portion 11 of the recess 7 of the tail boom 4 is a capsule 12 with a only when hitting a target (eg a tank) 13 ( Figure 2) ignitable fire sentence 14.
  • the fire sentence 14th is arranged displaceably in the recess 7 in the direction of the longitudinal axis 6 of the balancing projectile 1.
  • the torn-open capsule 12 flies due to their inertia from the vacant opening 16 of the recess 7 of the tail boom 4 behind the penetrator 2 ago and breaks up, for example. on the back wall or on objects in the tank, thereby releasing the fire charge. This reacts with the atmospheric oxygen, so that a hot, marsprühender sparkling rain with considerable fire effect arises.
  • the combustion energy is increased by the addition of boron, so that a correspondingly greater effect is achieved in the target due to the greater heat.
