Abstract : A system and process for on-demand generation of inert, non-flammable gases and water vapor to decrease the available atmospheric oxygen in the ullage of a hydrocarbon fuel storage tank to a level that will not support combustion of the hydrocarbon fuel, is disclosed. One, or more, of a variety of non-Halon, fire suppressor charges are selectively contained in one or more gas generating cartridges. The gas generating cartridge(s), when activated, cause release of these charges to prOmote rapid chemical reactions and supply inert, non-flammable gases and water vapor to the tank ullage. Activation is accomplished in aircraft by, either pilot action or, by pressure and temperature sensors contained within the hydrocarbon fuel tank.
