Description

gescrtøtion [0001] The invention relates to target marking ammunition, in particular for mortals and artillery.

[0002] In particular in the case of exercises in fire hazard regions, due to known practice ammunition with pyrotechnic target marking (hot burning particles) or in the case of live ammunition, such as, for example, HE, smoke and light ammunition, there is a risk of ignition and fires associated therewith, in particular ground fires. The so-called wildfire risk in the region also plays a large role here.

[0005 j To carry out exercises in such regions, inert projectiles without terminal effect are used. This is in particular problematic m the case of target practice with observers in the target region, because the point of impact/striking point of the projectile cannot be localised or can only be localised with difficulty. A response from the observer to the firing squad relating to the direction of the weapons is thus difficult.

[00041 A projectile comprising marking of the striking point is known from DE 10 2005 053 491 AI in the head area, the training projectile has a hollow ogive, in which a first chemically inactive and a second chemically active marking substance are accommodated. The first marking substance creates a colour effect, the second marking substance creates a light effect. The ogive itself must burst for this purpose.

[0005] AT 384 671 B describes a training projectile comprising a grenade body and a hollow space containing a powdery marking medium. The hollow space has discharge ducts, which are closed to the outside by means of small closure plates An axially displaceable striker, which includes a cartridge (blank cartridge), adjoins this hollow space from the top. When striking the training projectile, said cartridge is ignited. The gas pressure created thereby by means of the explosion of the propellant has the effect thai the marking medium is pushed out laterally and that the small closure plates are pressed out. in the alternative, an escape of the marker medium on the tail side is provided.

[0006] US 5 565 649 A describes the use of a piston in a projectile to distribute a marking substance, wherein the outer casing of the projectile is torn open at predetermined breaking points.

[0007] The invention here has the object of creating an ammunition, which marks the point of impact in a simple way by means of a temporary visual marking.

[0008] The object is solved by means of the features of patent claim T. Advantageous embodiments are included in the subclaims.

[0009] The invention is based on the idea of incorporating a container, which contains a means for marking the target, in the ogive area of the projectile for the purpose of marking the point of impact of a projectile. When the projectile strikes the target, the container is broken, so that the means for marking can emerge through holes introduced in the ogive or in the tail area. So that it can emerge in this form, a positive pressure is generated in the projectile, which is realized by means of a gas cartridge comprising a triggering mechanism or a reciprocating piston or the like.

[0010] A piston and / or a gas cartridge, by means of which an internal pressure is built up and a preferably luminescent fluid is output via holes, are thus incorporated in the body of the projectile. This fluid is characterized m that it can be used for daytime and night-time marking.

[0011] The reciprocating piston is either displaced mechanically axially by a preferably defined deformation of the body of the projectile in order to build up the internal pressure. The gas cartridge is thereby triggered by means of a triggering mechamsm, which, in turn, is triggered directly or via a detonator when the projectile strikes. The destroyed fluid container releases the fluid for marking via holes in the ogive or in the tail pan. The outputting of the preferably luminescent mass takes place without pyrotechnic means or disassembling of the body of the projectile with fragmentation. The defined deformation for the reciprocating piston can be created by means of the detonator, which is embedded frontally in the projectile.

[0012] The advantages are, among others, that no fire danger exists any longer and that a good visibility of the wreath-like point of impact is created during the day and at night, without having to create a colour marking and a light effect. Furthermore, a fragmentation of the ogive is not necessary'. The projectiles have a simple and safe handling and have a ballistic equality to existing projectiles [0013] The invention is to be described in more detail by means of an exemplary embodiment with drawing.

Fig. 1 shows a projectile comprising a gas cartridge in section,

Fig. 2 shows a projectile comprising a reciprocating piston in section.

[0014] Fig. 1 illustrates a projectile 10, here a training mortar, comprising a gas cartridge 7 and a triggering mechanism 8 for the gas cartridge 7 in section slightly stylistically, I identifies a detonator, 2 at least one, preferably a plurality of holes, 3 a container, here a fluid container containing a fluid. The latter is enclosed by an ogive 4, which protects the entire system and which furthermore contains an inert mass 5. The latter serves to secure the ballistic equality. As known in the case of a mortar projectile., ’carious holes, through which the propellant, which is not illustrated in detail, is ignited, is located in the tad (· [0015] The holes 2 are preferably incorporated on the circumference of the ogive 4 or in the tail area, preferably symmetrically spaced apart from one another, [0016] Fig. 2 shows a further projectile 11, also a training mortar, which, instead of the gas cartridge 7 comprising triggering mechanism 8, has a reciprocating piston 9.

The function is as follows;

When the projectile 10 or 11, respectively, strikes, the gas cartridge 7 is triggered by means of the triggering mechanism 8 or the reciprocating piston 9 is actuated, respectively, by means of the impact pulse. The fluid container 3 is destroyed by means of the positive pressure in the interior of the projectile 10, 11. When escaping from the ogive 4 through the holes 2, the preferably luminescent fluid located therein mixes. The target marking in the target area is triggered almost simultaneously with the impact of the projectile 10, 11 by means of this process and is visually displayed for an observer, who is not illustrated m detail.

[0017] To support the function of the gas cartridge 7 or of the reciprocating piston 9, the detonator is frontally incorporated m the ogive 4.
