According to the invention, an ammunition for marking a target person is proposed, comprising
a projectile and an associated propellant charge case in which a propellant charge is received,
wherein the projectile comprises a sabot and a projectile head, wherein the sabot is designed as a tail and
wherein in the projectile head made of plastic, a cavity is formed, in which a marking agent is received.

The propellant charge case may be a conventional propellant case for firing a projectile. The projectile is accommodated at least with a part of the tail in the propellant charge shell. The projectile head protrudes from the propellant charge envelope.

The propellant charge is z. B. ignited by means of a propellant charge igniter. Ignition of the propellant ejects the projectile from the barrel of the weapon.

The projectile is inventively provided with a tail. The tail unit is designed so stable that it serves as a sabot. The tail unit is suitable for improving the aerodynamic properties of the projectile. For this purpose, the tail has in the axial direction of the projectile expediently a thickness between 5 and 20 mm, in particular 10 to 15 mm.

The projectile expediently comprises an integrally formed rear section, which comprises the tail unit and a fuselage structure extending from the tail unit in the axial direction. The hull structure may comprise a part of the projectile head at its front end facing away from the tail. A forward portion of the projectile is formed from a cap forming the projectile head, which is connected to the body portion. The cap closes the cavity in the projectile head. The cap forms another piece, which is welded or glued to the body portion.

It may also be that the projectile head is formed from a sphere in which the marking means is received. In this case, the ball is fixed in a corresponding concave recess at the front end of the fuselage. The attachment can in turn be done by welding or gluing.

In the projectile head a marking agent is added, which serves to mark the target person. The marking agent is suitable for producing a highly visible mark on the target person and / or the target object, which can not be easily removed by water. The projectile head is made of a plastic. The plastic consists of a soft, easily deformable and / or destructible material, so that injury to the target person when hitting the projectile is avoided.

To avoid injury to the target, an energy density criterion must be met. The energy density criterion states that the energy density is limited to 0.1 J / mm ^{2 to} preclude penetration into the skin. To comply with the energy density criterion, the propellant charge is adjusted so that the maximum velocity of the projectile is a maximum of 50 m / s.

Conveniently, the projectile made of polyurethane (PU), in particular PU foam. The projectile can thereby a small Weight of at most 40 g. The material of the projectile is in particular selected so that injuries to the target person can be excluded.

The tail can expediently be a cylindrical tail unit or a conical structure. By the tail, the trajectory of the projectile can be stabilized. It can be achieved a significantly improved accuracy of hit with an operating range between 20 and 50 m.

Reinforcing materials which lead to increased stability of the projectile can be integrated in a tail section of the projectile facing the tail. The reinforcing materials may extend axially into the area of the tail. In particular, can be made of plastic or a composite material cast as a reinforcing material.

The tail may in a further embodiment, preferably axially extending, have openings and / or slots. The apertures and / or slots are adapted to improve the aerodynamic properties of the projectile. The openings and / or slots affect the function of the tail as a sabot. Conveniently, another sabot between the tail and projectile head can be arranged. Alternatively, the projectile head can be designed such that a side of the projectile facing the tail, the ogive of the projectile, serves as a further sabot.

Conveniently, the marking agent is a liquid containing a dye. This is suitable for marking the target person so that the marking is clearly visible from a distance of several meters. The marking agent is expediently neither toxic nor harmful to the environment. The dye may be, for example, rhodamine B. The liquid can z. B. based on propylene glycol and water.

Advantageously, the marking agent is liquid between -46 ° C and + 71 ° C. Thus, the marking agent is universally applicable in all climates.

In another embodiment, the marking agent is contained in a closed-cell polyurethane foam shell. The polyurethane foam is preferably a rigid foam having a density of 0.05-0.5 g / cm ³ , preferably 0.1-0.3 g / cm ³ . In this case, the marking means with sheath is accommodated in the cavity of the projectile head.

The marking agent is preferably taken up in a carrier material designed as an open-celled foam. The carrier material is preferably a phenolic resin foam having a density of 0.01-0.03 g / cm ³ , in particular 0.02 g / cm ³ . This carrier material is enclosed by the shell. Advantageously, the envelope forms a sphere with the carrier material and the marking agent. The enclosed by the shell substrate is z. B. placed in the rear portion of the projectile and then with the front portion of the projectile z. B. enclosed by welding. Upon impact of the projectile on the target person, the shell bursts and the marking agent is thereby distributed to the target person.

In particular, the ammunition has a caliber of 30 to 50 mm, preferably 40 mm. The ammunition is suitably suitable for firing with a handgun, in particular a rifle or a grenade pistol.

An embodiment of the invention will be explained in more detail with reference to figures. Show it:

1 a schematic representation of a projectile with conical structure and

2 a cross section through the active agent.

The projectile 1 in 1 consists of a projectile head 3a . 3b , Tail sections 5 and a tail unit 2 , Propellant charge tube and propellant charge are not shown. The tail unit 2 In this case it is designed as a conical structure. The projectile head 3a . 3b includes a front half shell of the projectile head 3a and a rear half shell of the projectile head 3b , These are z. B. connected via a weld, which is a material weakening line 4 forms. Upon impact, the projectile head preferably bursts at the material weakening line 4 ,

The tail sections 5a . 5b taper in a direction away from the projectile head, so that in the rear tail section 5b the diameter of the projectile is the lowest. At the stern section 5b closes the tail 2 at. The tail unit 2 also serves as a sabot. Appropriately, are in the tail 2 cylindrical breakthroughs 6 intended. The breakthroughs 6 serve to improve the stability of the trajectory. In this case, the ogive of the projectile is in the area of the projectile head 3b designed so that a seal against the propellant gases and serves as another sabot. Alternatively, an unillustrated further sabot is provided in the region of the rear sections. The marker is in the projectile head 3a . 3b added.

The marking agent is in the exemplary embodiment of a marking agent carrier 8th which is in 2 is shown applied. The marker carrier 8th is suitably made of an open-cell foam. To avoid leakage of the marking agent, the marker agent carrier becomes 8th from a shell 7 enclosed. The case 7 can be foamed on the open-cell foam and consist of a closed-cell foam. The marker carrier 8th serves to keep the fluid distribution the same even during acceleration. Thus, the weight distribution in the projectile remains constant and the flight characteristics of the projectile are improved.

The ammunition is fired by a suitable weapon. When firing the ammunition, the tail of the projectile serves as a sabot, so that the projectile is ejected from the barrel of the weapon by the propellant gases. In a tail with breakthroughs, some of the propellant gases escape from the breakthroughs, so another sabot is needed to reliably accelerate the projectile. A designed as a sabot ogive of the projectile or another arranged between the tail and projectile head sabot can serve as another sabot.

When the ammunition hits the target person or another target object, the projectile head bursts 3a off and the case 7 opens so that the marking means produces a highly visible mark on the target person and / or target object. Conveniently, this mark is not removed by simple washing.
