摘要: An igniter for a bore safe flare comprising a piston member and a cap mem designed to cause ignition only after the flare grain has cleared the launcher. Flame from the firing charge cannot reach the flare grain for ignition until separation of cap and piston. The cap member is fixed in the base of the flare grain and carries the ignition mix which projects into a central bore of the piston.
