<p>Electronic Firing Device for Missiles An electronic firing device of a missile, enabling precise setting of a time delay from several milliseconds up to an hour or more, comprises an energy source formed by a capacitor associated with a coupling coil charging the capacitor from an external signal. This signal has a low frequency energy-supply component carrying a high frequency signal having a series of pulse trains defining a decimal number up to, for example, 107. The high frequency signal passes via a coded selective filter supplying, to a memory, a coded value defining a time delay . An oscillator triggered by a security switch supplies clock signals which are divided to provide 1 millisecond pulses counted in a coding circuit in the same code as the memory. This coding circuit and the memory are connected to a comparator which supplies a firing signal when the count reaches the memorized value.</p> |
