Benefits of technology

[0010] The object of the invention is to provide a device or an improved programming system that is no longer exposed to mechanical and thermodynamic wear.

Problems solved by technology

Although the above device is distinguished by a high degree of accuracy, it is subject to mechanical and thermodynamic stresses, since the measuring and programming units are exposed, among other things, to the muzzle gases.

Embodiment Construction

[0023] The sole drawing shows a programming system 1 or a generalized device for a time-fuse projectile 2 or a time-fuse piece of ammunition (etc.).

[0024] A programmable chip 3, for example, an RFID chip, is located on board the projectile 2 and preferably also contains the receiving and transmitting circuit and memory. A timer 4 present in the projectile 2 is also supplied by this chip 3 with the necessary time information on the spot. Parallel to this, the chip 3 is connected with a computing and / or correction unit 5 if such a unit is provided in the projectile 2. This unit 5 is then also connected with the timer 4. A fuse 6 is functionally connected with the output of the timer 4.

[0025] The power supply to these units of the projectile 2 can be provided by microwave radiation X. Another, preferred possibility is a conventional power supply, for example, a battery that can be activated (not shown).

[0026] On the cannon or weapon end 10, the programming system 1, which is prefera...

Abstract

To avoid mechanical and thermodynamic wear of a programming system, a microwave transmitter, preferably operating in the GHz range, is integrated in the system, while at the same time the advantages of measurement of the muzzle velocity and of a current compensated fuse setting are preserved. The microwave transmitter transmits the current fuse setting, for example, as determined by a fire control computer, to the ammunition, e.g., a projectile. A direct measurement of the actual muzzle velocity itself can be dispensed with, since the real muzzle velocity is determined by the current flight velocity information of the projectile, i.e., it is extrapolated back from this. On the basis of this current projectile velocity, the ignition time, which was preset with the ignition time of the projectile using a standard muzzle velocity, is corrected and used as the current fuse set time.

Description

BACKGROUND OF THE INVENTION [0001] The invention concerns a method and a device for programming a time-fuse projectile or for correcting an ignition time of a projectile fired from a weapon. [0002] Various time programmings for ammunition are known. The fuses are set either manually outside the loading chamber before the projectile is fired or electrically in the loading chamber by ignition electronics. The latter type of fuse setting is described, for example, in DE 101 52 862 A1. [0003] A method and a device for transmitting information to programmable projectiles are described in EP 0 992 762 B1. [0004] A method for correcting the preprogrammed triggering of a process in a spin-stabilized projectile and a device for carrying out this method are described in EP 0 992 761 B1. [0005] EP 0 918 209 B1 discloses a projectile with programmable time fuses. [0006] A method and a device for programming time fuses of projectiles are also described in EP 0 769 673 B1. To compute a disintegra...
