Abstract

A fire suppressing gas generator includes a cylindrical housing comprising an array of discharge ports distributed generally uniformly there around; a cylindrical filter disposed within the housing and spaced from the interior wall of the housing; a plurality of azide-based propellant grains inside the cylindrical filter; and at least one ignition de­vice associated with the propellant grains. The propellant grains when ig­nited by the ignition device generate a fire suppressing gas which passes through the filler and out of the discharge ports of the cylindrical housing for delivery into a space.
