• the projectile may be both a combat and a practice bullet.
• the US 3,712,228 discloses a pyrotechnic marker for a steering column to indicate the point of the warhead detonation, thereby enabling accurate firing of conventional weapons against the chosen target.
• the entire warhead portion of the projectile can form a marker warhead, which in addition to a Deutladung an explosive charge sufficient to destroy the required for the steering of the basement section.
• Object of the present invention is to provide an active mass that allows an alternative Deutse effect. Furthermore, a combat ammunition comprising this active mass and a use for producing this active mass should be specified.
• an explosive active mass for a combat ammunition which comprises an explosive and particles and / or pieces of an indexing agent homogeneously distributed in the explosive active mass.
• the particles and the pieces are each independently formed from at least one of the elements titanium, zirconium, boron or hafnium, a ferrotitanium, a silicide, ferrosilicon or a mixture thereof.
• the particles or pieces can be, for example, particles or pieces of an alloy or a mixture of particles or pieces formed from different substances.
• the pieces have a sponge-like structure. They may in particular be formed from titanium, zirconium or hafnium. In the explosive active mass may also be a mixture of the sponge-like pieces and the particles or of different particles.
• the explosive active material according to the invention has a much stronger and spatially more extensive German effect. Compared to a corresponding explosive active material without the particles or pieces of the Deutffens, the explosive active material according to the invention has an at most insignificantly reduced explosive effect. The particles and / or pieces can also contribute to the explosive effect.
• the hit position of a combat ammunition containing the explosive active material according to the invention can also be located well from a great distance.
• a combat enemy can be fooled and blinded by the actual explosive effect due to an intense optical effect associated with the detonation of the explosive active mass. Due to the intense optical effect, the opponent will assume a much stronger than the actual explosive effect.
• the explosives active substance according to the invention can thereby also have a psychological effect. In the case of detonation, flying sparks automatically trigger an evasive reaction in humans, which does not trigger conventional splinters. A detonation effect associated with the detonation is much higher than in the detonation of a conventional explosive active material.
• This effect may be more intimidating for certain target groups, such as partisans or occasional fighters It can be achieved with conventional explosives or ammunition with a known Deutladung.
• the psychological effect and / or the dazzling effect can lead to a suppression of an opposing attacking activity.
• the silicide may comprise magnesium silicide or calcium silicide.
• the particles of titanium and boron formed particles may form in the reaction of the explosive active material according to the invention TiB 2 . In this case, a relatively large thermal energy is released and thereby increases the blast effect of the explosive active mass.

• a measurable property of the particles is determined.
• the determined property is then related to spheres having the same property.
• the equivalent diameter is the diameter of these balls.
• the equivalent diameter may in particular be a screen diameter.
• the particles may be spherical particles. In this case, the equivalent diameter is identical to the actual diameter of the particles. The smaller the equivalent diameter of the particles, the faster they are converted in a reaction of the explosive active material. This enhances the blasting and blinding effect.
• the explosive active material according to the invention comprises a further, fog-forming deuterium.
• This may be a so-called Berger mixture, in particular a zinc-CCl4 mixture, preferably comprising Zn, ZnO, MgO and CCl4 act.
• the further reductant may include red phosphorus and an oxidizing agent, especially potassium nitrate, and optionally a binder.
• the explosive active mass may comprise the pieces and the further deuter means may be included in the sponge-like structure of the pieces.
• the pieces burning in the air create a smoke trail in the air and at the same time produce a bright light.
• the German effect is easily detected under all lighting conditions from a large distance.
• the further deuterium or the pieces with the further deuterium added in the sponge-like structure of the pieces may be enveloped by a combustible coating, a combustible polymer or the binder. It can thereby be achieved that another deuterium, whose reaction would reduce the detonation performance of the explosive active mass without the sheathing, has no or no significant effect on the detonation performance of the explosive active mass.
• Another Deutstoff is z.
• B. another deuterating agent comprising red phosphorus By enveloping the reaction of further Deutstoffs is delayed so far with the formation of explosive swaths that the performance of the explosive is not or not significantly affected. Even by the mere introduction of the further Liebe agent in the sponge-like structure of the pieces can already delay the reaction the further Deutstoff be achieved, which is sufficient to prevent a reduction in the detonation performance, at least largely.
• the explosive active mass comprises the pieces which have a sponge-like structure, the pieces being formed from titanium. Titanium emits a particularly bright light when burned, which is clearly visible even in daylight. It has proved to be particularly effective if the active mass comprises, in addition to the pieces of titanium, said particles, in particular when the further deuterium has been taken up in the sponge-like structure of the pieces. It is advantageous if the particles are also formed of titanium, in particular, if the particles are spherical.
• the explosive active mass comprises further particles which are formed from magnesium and / or aluminum.
• aluminum increases the explosive effect
• magnesium increases the lighting effect during the implementation of the explosive active mass.

• the invention further relates to a combat ammunition comprising an explosive active material according to the invention, wherein the combat ammunition does not comprise any further explosive active mass or comprises a further explosive active mass, wherein the further explosive active mass is surrounded by the explosive active mass.
• the total proportion of the particles and / or pieces and optionally of the further deuterium and / or the further particles in the sum of the weight of the explosive active material and the further explosive active mass may be 5 to 15% by weight.
• the combat ammunition may be, for example, a grenade, in particular a fragmentation grenade or an infantry grenade, in particular an infantry grenade with a caliber of 40 mm, or a mortar shell, in particular a mortar shell with a caliber of 60 mm act.

• a fragmentation grenade is in the explosive material "Hexal" usually used, which consists of 65 wt .-% Hexogen, 30 wt .-% aluminum powder and 5 wt .-% wax and has a moderate fragmentation effect with high explosive effect, the proportion Aluminum powder reduced to 15 wt .-%. Instead of this proportion of aluminum powder, 15% by weight of titanium-formed pieces having a sponge-like structure and an equivalent diameter of 1 to 2 mm are introduced into the explosive active mass and homogeneously distributed in the explosive active mass. As a result, a fragmentation grenade is obtained with at most insignificantly reduced explosive effect and very strong Deutrial.
