Abstract
An electric igniter assembly for igniting an initiator charge in artillery mmunition. The initiator charge is enclosed within a chamber sealed at one end by an electrical ignition element comprising two conductors linked by means of an electrically resistive bridge, one of which conductors is in permanent electrical contact with a DC supply terminal and the other of which is connected to a contactor block thereby permitting contact with a complementary DC supply terminal, so as to complete the circuit through the resistive bridge which glows, thereby sparking off the initiator charge. The novel igniter assembly features a relatively low margin between the values of current intensities for 'NO FIRE' and 'ALL FIRE' while at the same time avoiding electromagnetic radiation hazards (HERO).
