Abstract:
1. A fire suppressing gas generator comprising: a cylindrical housing comprising an array of discharge ports distributed thereon; a cylindrical filter disposed within the housing and spaced from an interior wall of the housing; a plurality of azide-based propellant grains inside the cylindrical filter, the plurality of azide-based propellant ant rains comprising at least one column of stacked propellant grains; and at least one ignition device associated with the propellant grains wherein the at least one column comprises an end grain at each end thereof that includes a central bore dimensioned to receive at least a portion of the ignition device therein; wherein the propellant grains when ignited by the ignition device generate a fire suppressing gas which passes through the filter and out of the discharge ports of the cylindrical housing for delivery into a space, and wherein the distribution of the discharge ports on the housing provides substantially thrust neutrality to the generator when the fire suppressing gas passes out of the discharge ports.
