Abstract

The invention relates to an incendiary device (14) for a wing - stabilized balancing projectile (1) which can be arranged in the rear region of the projectile (1) and hitting a target (13) behind the penetrator (2) of the projectile projectile (1) as a separate unit the target (13) penetrates. In order to achieve that the fire set (14) despite a relatively small volume and a low mass causes a large destructive effect within a target (13) and is safely ignited by the shock waves generated upon impact on a target, the invention proposes, as Brandsatz (14) to use a titanium sponge, wherein an epoxy or polyester resin is used as a binder. <IMAGE>

Description

The invention relates to an incendiary device for a wing stabilized balancing projectile, which in the Rearward area of the projectile can be arranged and when hitting a target behind the projectile Penetrator of the bullet as a separate unit penetrates into the target.

Wing stabilized balancing projectiles, in which incendiary devices in the rear area of the Bullet are arranged, for example, in the German patent applications DE 199 48 708.1 and DE 199 48 710.3. In such balancing bullets is replaces the commonly used tracer set with the set of flames to achieve that the bullet when hitting on semi-hard targets (for example, with a relative thin armor provided infantry fighting vehicles) unfolds a considerable fire effect. Because without such a fire sentence of the penetrator of the bullet would be the fly through a semi-hard target and have no significant destructive effect on it, but only a maximum projectile diameter corresponding hole in create the armor.

In DE 199 48 710.3, it is already stated that the rear side in the balancing projectile arranged fire rate can also be chosen such that it by the at Impact on a corresponding target shock wave is initiated, but revealed this document no further details about the concrete structure of such Incendiary.

DE-AS 29 01 517 are incendiary, consisting of a metal sponge and an organic Binders are known. In this case, preferably a metal sponge of zirconium or hafnium and used as a binder polytetrafluoroethylene. As Experiments of the Applicant have revealed, these known incendiary are not optimal can be initiated by shock waves, especially not if only relatively small Quantities of the corresponding fire rate can be used, as this at the Tracer replacing lightning incendiaries of balancing bullets is the case.

The invention is based on the object, incendiary for wing-stabilized balancing projectiles which despite a relatively small volume and a low mass cause a large destructive effect within a target and upon impact a target can be safely ignited by the resulting shockwaves.

This object is solved by the features of claims 1 and 3. Further advantageous Embodiments of the invention disclose the subclaims.

Essentially, the invention is based on the idea, as fire set a titanium sponge to use, as an epoxy or polyester resin binder used becomes. Since the incendiary contains no oxygen carrier, it is relatively insensitive.

At the target impact, the titanium sponge particles are then heated up to the ignition temperature and continue to burn intensively with release of the particles with the atmospheric oxygen.

In experiments, it has been shown that the relatively brittle titanium sponge due to its low Ductility is much better suited as a fire rate than ductile materials, such as such as zirconium, magnesium or aluminum powder. In addition, the inventive effect Fire kits also set fire to flame retardant oils (such as diesel or Hydraulic oil).

Another advantage of the incendiary invention is that they are normal Condition behave like an inert material and only with a very strong impact can be brought to inflammation. It is therefore also in case of missing the goal one Safe handling of the projectile possible if the fire is not damaged.

In a first advantageous embodiment of the invention, 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.

To increase the energy content (increase in the enthalpy of combustion) has proven to be advantageous to mix the fire rate 10 to 20 wt .-% boron powder, the grain size of the boron powder should preferably be ≤ 10 microns. In a second embodiment, 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 .

For a maximum fire effect in the combat area of a corresponding armored vehicle To reach, it has proved to be useful, the grain size range of the titanium sponge to be chosen such that 30% of titanium sponge particles have a particle size greater than 450 microns and 70% have a particle size less than 450 microns.

Further details and advantages of the invention will become apparent from the following with reference to figures explained embodiment. Show it:

  • Figures 1 and 2 each show the longitudinal section of a blasting project containing the inventive fire sentence, before and after hitting an armored target.
  • In Fig.1, 1 denotes a large-caliber wing-stabilized balancing projectile, as it is for example, from tank cannons is fired. The balancing projectile 1 comprises a Penetrator 2 and attached to the penetrator tail 3. This consists essentially from a sleeve-shaped tail boom 4 with stabilizing wings arranged on the outside 5 and in the direction of the longitudinal axis 6 of the balancing projectile 1 extending and on the penetrator 2 side facing by this closed Recess 7.

    The rear-side area 8 of the penetrator 2 extends into a second partial area 9 of the recess 7 and is connected to the tail unit 4, e.g. via a threaded connection 10 positively connected.

    In a rear portion adjoining the second portion 9 first portion 11th the recess 7 of the tail boom 4 is a capsule 12 with a first at Impact on a target (for example, a tank) 13 (Fig.2) ignitable fire sentence 14. The Fire sentence 14 is in the recess 7 in the direction of the longitudinal axis 6 of the balancing projectile 1 arranged displaceably.

    If the power projectile 1 hits the relatively thin wall 15 of the oblique target 13 (e.g. at an angle of 60 °), so penetrator 2 initially penetrates this wall largely unhindered. As soon as the tail unit 3 hits the wall 15, this is due to their large diameter and the associated resistance of the penetrator 2 separated and remains either in the wall 15 of the target 13 or flies with essential reduced speed than the penetrator 2 further, the stabilizing wings 5 of the tail unit 3 splinter and the capsule 12 of the fire sentence 14 at least in some areas tears.

    The torn capsule 12 flies due to their inertia from the released Opening 16 of the recess 7 of the tail boom 4 behind the penetrator 2 ago and shattered e.g. on the back wall or on items in the tank and gives it the fire sentence free. This reacts with the atmospheric oxygen, so that a hot, weitsprühender Sparks rain with considerable fire effect arises.

    For example, as incendiary mixtures, the two following mixtures were advantageously used:

  • 1. 96% by weight of titanium sponge (particle size range: 30% greater than 450 μm, 70% less than 450 μm)
    4% by weight of epoxy resin (araldite)
    Pressing the mixture to a density of 2.5 g / cm 3
  • 2. 80% by weight of titanium sponge (particle size range: 30% greater than 450 μm, 70% less than 450 μm)
    5% by weight of epoxy resin (araldite)
    15% by weight boron powder (particle size range: ≦ 10 μm)
    Pressing the mixture to a density of 2.5 g / cm 3
  • In the second embodiment, by adding boron, the combustion energy becomes increased, so that in the target due to the greater heat a correspondingly larger Effect is achieved.
