Abstract

In connection with a projectile, the effective substance (4) is designed as a projectile core (3), which is held in place by a propulsion reflector sheath (1) and a propulsion reflector back (2). The data reception coil (13) and the power supply (14) are arranged in the propulsion reflection back (2), while the remaining elements (9, 10, 11, 12) of the programmable time fuse (8) are installed in the projectile core (3, 25). Predetermined breaking points are provided in the propulsion reflector sheath (1) and the propulsion reflector back (2), so that following the firing of the projectile, the propulsion reflector sheath (1) and the propulsion reflector back (2) with the data reception coil (13) and the power supply (14) are separated, and only the projectile core (3) with the remaining elements (9, 10, 11, 12) of the programmable time fuse (8) alone continue to travel.

Claims

1. A projectile with a programmable time fuse having at least one data reception coil and a power supply, as well as an effective substance, which is disaggregated, or respectively ejected, at the end of a programmed fuse setting time,

the improvement comprising

the effective substance is designed as a projectile core, which is held in place by a propulsion reflector sheath and a propulsion reflector back,

the data reception coil and the power supply are arranged in the propulsion reflection rear, while the remaining elements of the programmable time fuse are installed in the projectile core, and

predetermined breaking points are provided in the propulsion reflector sheath and the propulsion reflector back, so that following the firing of the projectile, the propulsion reflector sheath and the propulsion reflector back with the data reception coil and the power supply are separated, and only the projectile core with the remaining elements of the programmable time fuse continue to travel.

2. A projectile in accordance with claim 1, wherein

the effective substance consists of lined-up, metallic, disk-shaped bodies, which are prefragmented for a defined fragment size.

3. A projectile in accordance with claim 2, wherein

bores or notches have been provided in the bodies for the purpose of prefragmentation.

4. A projectile in accordance with claim 1, wherein

the effective substance consists of a frangible heavy metal.

5. A projectile in accordance with claim 1, wherein

the projectile core is designed as an arrow.

6. A projectile with a programmable time fuse having at least one data reception coil and a power supply, as well as an effective substance, which is ejected at the end of a programmed fuse setting time,

the improvement comprising

the effective substance is arranged in a projectile core, which is held in place by a propulsion reflector sheath and a propulsion reflector back,

the data reception coil and the power supply are arranged in the propulsion reflection back, while the remaining elements of the programmable time fuse are installed in the projectile core, and predetermined breaking points are provided in the propulsion reflector sheath and the propulsion reflector back, so that following the firing of the projectile, the propulsion reflector sheath and the propulsion reflector back with the data reception coil and the power supply are separated, and only the projectile core with the remaining elements of the programmable time fuse continue to travel.

7. A projectile in accordance with claim 6, wherein

the effective substance consists of a plurality of sub-projectiles made of a heavy metal.

8. A projectile in accordance with claim 7, wherein

the sub-projectiles have a cylindrical shape and are combined into sub-projectile columns, extending in the longitudinal direction of the projectile.

9. A projectile in accordance with claim 8, wherein

arrows are used in place of the sub-projectile columns.
