  • Patent number: 4240350
    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.
