TIME FUZE OF SHELLS OF SALVO-FIRE JET-PROPELLED SYSTEMS (SFJPS) Russian patent published in 2004 - IPC

FIELD: use of shells of salvo-fire jet-propelled systems, when the fixed rate of fire needs automatic programming in the interval between launchings of shells adjacent in time.

SUBSTANCE: the time fuze has a power supply source, electronic timing device, safety-actuating mechanism and a receiving device, the induction coil is positioned on the outer surface of a tubular ferrite core. Installed in the inner cavity of the core is a screen of soft magnetic metal placed in which screen of soft magnetic metal placed in which is a capacitor supply source, electronic timing device with an inertia switch, additionally used is a selector of programming command pulses. The induction coil has taps from the inner turns, which via a rectifier are connected to the input of the pulse selector and via an additional diode - to the capacitor supply source, and the output of the pulse selector is connected to the adjusting input of the electronic timing device, connected to whose power line is the capacitor supply source. The programming command pulse selector has a differentiating circuit of a capacitor and a resistor with a time constant equal to the duration of the adjusting programming command pulse, and a diode. The efficiency of target destruction is enhanced due to enhanced accuracy of remote action time countdown and enhanced efficiency of conversion of electromagnetic field to an electric signal at programming, i.e. at transmission of energy for electric power supply of the fuze electronic circuit and programming signals in the conditions of a fixed rate of fire of the SFJPS.

EFFECT: enhanced efficiency of target destruction.
