Gap initiation with 20.35 mm: an initiator integrating the Al/CuO_x multilayer film and traditional electronic plug to enhance the ignition ability.

ABSTRACT: In order to enhance the ignition ability and reliability of traditional electronic initiators, a novel electronic initiator has been designed to integrate with a nanothermite multilayer film and an electrode plug. The Al/CuO_x nanothermite multilayer film with different thickness is deposited on the surface of the electrode plug by magnetron sputtering which uses Pt-W wire as electronic resistance. The exothermicity of Al/CuO_x nanothermite multilayer film is so favourable that the ignition ability of electronic initiator is significantly improved. The full firing-voltage sensitivity of the electronic initiator is 10.8 V. The thickness of Al/CuO_x multilayer film has negligible effects on the ignition time and ignition energy, but leads to great impacts on the
