## CPC

- F42B 12/367: {Projectiles fragmenting upon impact without the use of explosives, the fragments creating a wounding or lethal effect (practice or training projectiles disintegrating upon impact F42B8/14; projectiles of high-explosive type with fragmentation-hull construction F42B12/22)}
- F42B 12/06: with hard or heavy core; Kinetic energy penetrators (F42B12/16, F42B12/74 take precedence)
- F42B 12/46: for dispensing gases, vapours, powders or chemically-reactive substances (F42B12/70 takes precedence)
- F42B 12/44: of incendiary type (F42B12/46 takes precedence)
- F42B: EXPLOSIVE CHARGES, e.g. FOR BLASTING, FIREWORKS, AMMUNITION (explosive compositions C06B; fuzes F42C; blasting F42D)

## Abstract

The invention relates to a projectile (1, 8, 9) having at least one payload (5) or explosive charge in the projectile body (2, 7, 10), preferably in the medium caliber range, the payload (5) being integrated into the projectile body (2, 7, 10) in the form of a pyrotechnic charge. The payload (5) can preferably be enclosed and sealed by a core (6, 14) which preferably consists of metal or plastic. In an alternative embodiment, the pyrotechnic payload (5) is disposed behind a penetrator (11) in the projectile body (10), the payload (5) thus being located between the penetrator (11) and the projectile body (10).

## Claims

### Claim 1

A projectile having at least one projectile body, a core, and a payload, wherein the payload is at least a pyrotechnic composition, wherein the core encloses and seals the pyrotechnic payload, and wherein the pyrotechnic payload is configured to initiate in response to a shockwave formed upon impact of the projectile at a target, independent of a separate pyrotechnic composition.

### Claim 2 (depends on 1)

The projectile as claimed in claim 1, wherein the pyrotechnic payload is non-detonatable.

### Claim 3 (depends on 1)

The projectile as claimed in claim 1, wherein the core is a metal or a plastic.

### Claim 4 (depends on 3)

The projectile as claimed in claim 3, wherein the pyrotechnic payload is introduced between the projectile body and a penetrator.

### Claim 5 (depends on 4)

The projectile as claimed in claim 4, wherein the pyrotechnic payload is disposed partially or completely about the penetrator.

### Claim 6 (depends on 5)

The projectile as claimed in claim 5, wherein the pyrotechnic payload is disposed in a ring-shaped manner about the penetrator.

### Claim 7 (depends on 1)

The projectile as claimed in claim 1, wherein the pyrotechnic payload is a material for producing a fire, fog, flash and/or bang effect.

### Claim 8 (depends on 1)

The projectile as claimed in claim 1, wherein the projectile body has predetermined breaking points on the circumference.

### Claim 9 (depends on 1)

A method of target engagement using a projectile according to claim 1, the method comprising:
producing the shockwave upon impact of the projectile for the formation of splinters or fragments of the projectile body at least, and
initiating the pyrotechnic payload by the initiated shockwave, so that the pyrotechnic payload reacts,
wherein the expanded gases of the pyrotechnic payload further accelerate the casing fragments of the projectile body surrounding them.
