PERFECCIONAMIENTOS EN DISPOSITIVOS ELECTRONICOS DE ENCENDIDODE CARGA PIROTECNICA.

摘要

An electronic firing device for a pyrotechnic charge in a projectile comprises a programmable unijunction transistor controlled by the discharge of a firing capacitor to fire an electric fuse. An oscillator supplies a pulsed output signal via a charging circuit to intermittently charge the capacitor in steps. The oscillator output signal is also supplied as a clock signal to a delay device controlling conduction of the transistor to fire the fuse after a given delay following an impact.
