Abstract: A method for programming the shattering of projectiles (G) and a weapon (12) with a programming system (14, 16, 18). The projectiles are intended to destroy a target (Z) at which they are fired along heavily curved trajectories and are detonated at shattering points near the target. The longitudinal distance (xZ) of the target from the weapon is measured and the elevation (?) is adjusted for which a known muzzle velocity (v0(0)) and a longitudinal distance of the shattering point at a predetermined optimal height (y*) are taken into consideration. The actual muzzle velocity (v0(eff)) is determined and a calculation for the programming is carried out in which the actual muzzle velocity is taken into account and the optimal height of the shattering point is held constant. The corresponding programming is transmitted to the projectiles. The weapon has an associated programming system for correspondingly programming the projectiles.

Abstract: A device (10) and a method for determining the muzzle velocity (V0) of the projectile (1) upon exiting a weapon barrel (11). The device (10) includes a coil (12), which is positioned around a longitudinal axis (11.1) of the weapon barrel (11) in the region before the exit, and a supply device (15) for impressing a current (I) in the coil (12) to generate a magnetic field (H). The device (10) additionally includes an analysis device (16), which reads off a voltage pulse on the coil (12), induced during the passage of the projectile (1) through the magnetic field of the coil (12). Two predetermined points of the voltage pulse are detected, the time interval between the two points is determined, and the muzzle velocity (V0) of the projectile (1) is calculated from the time interval.

Abstract: In order to improve the inductive transmission of pulses from a transmitter coil to a receiver coil of a projectile fuze, an insert formed of a steel band is mounted between a coil and a coil core formed of aluminum. This insert shields the coil against eddy current fields.

Abstract: Upon detonating a projectile in the proximity of a target, there are produced projectile fragments which fly towards the target in a predetermined direction. To have as many fragments as possible fly towards the target, the projectile must be detonated at a suitably selected angle measured between the line of sight which extends between the projectile and the target, and the projectile flight trajectory. This detonation angle varies as a function of the encountering velocity of the projectile and the target. A predetermined reference value associated with a predetermined encountering velocity value is computed using a stationary firing control system and represented by the quotient c/(2VBg), wherein c is the velocity of light and VBg is the predetermined encountering velocity value. Such reference value is stored in a storage device aboard the projectile.

Abstract: For small calibre projectiles the electrical energy needed for igniting a low-ohm ignition capsule is stored in a supply or ignition capacitor which, upon firing of the projectile, is charged by a current generator. To ensure that during charging of the supply capacitor upon firing of the projectile, the ignition capsule does not prematurely ignite, there are provided safety circuits, in particular a static blocking circuit, a dynamic blocking circuit and a static delatching circuit.

Abstract: An impact fuze with a time-delay between the impact of a flying object, such as a rocket or projectile at the target and the detonation thereof renders possible the penetration of the rocket or projectile into the target before the detonation. The flight velocity or speed of a projectile decreases with increasing flying time. In order to ensure for a penetration depth which nevertheless is sufficient, the impact time-delay must increase with decreasing flight velocity of the rocket or projectile. For this purpose, a time-delay counter is set by means of a self-destruction counter as a function of the flight velocity.

Abstract: In an electronic fuze for a projectile the ignition energy, upon firing of the projectile, is produced by a generator and stored in a storage capacitor. An electronic circuit serving for the barrel safety i.e. to prevent premature detonation of the projectile in front of the barrel, delaying ignition upon impact, the delay-free ignition upon impact and the self-destruction of the projectile, controls the delivery of the energy stored in the capacitor to the detonator or ignition cap. To ensure that the energy of the storage capacitor is sufficient the electronic circuit of the fuze must work with extremely low current. This is realized by providing for the circuit a stabilizer, a switching-on element, resetting elements, blocking elements and time-delay elements, the stabilizer and time-delay elements being structured as solid-state circuits.

Abstract: An apparatus for generating an electrical ignition current in the fuze of a projectile to be fired from a weapon, comprising an induction coil arranged in the projectile, a magnet for generating a magnetic field, a bipartite yoke, one part of which is located at the projectile and the other part at the weapon barrel, for producing a change in the magnetic flux upon passage of the projectile through the weapon barrel. According to one embodiment the part of the yoke located at the weapon barrel comprises a number of ferromagnetic rings and paramagnetic rings arranged between the ferromagnetic rings. The part of the yoke located at the projectile body comprises a substantially cylindrical body member having a substantially disc-shaped flange for the reception of the induction coil as well as a soft iron disc. With this arrangement the magnet is a permanent magnet which is disposed between this cylindrical body member and the soft iron disc.
