A method and apparatus are disclosed for pyrotechnically generating a mixture of at least two gases, substantially in a predetermined ratio, for an extended period of time, with separate pyrotechnic charges generating each component of the resultant mixture. At least one of the pyrotechnic charges is capable of sustained burning at a rate corresponding to the rate of total gas generation, and the remaining charges, not in themselves capable of sustained burning, are caused to sustain ignition by maintaining their burning surface in thermal communication with that of the first charge, so that all charges burn at substantially the same linear rate.

A method for generating a mixture of at least two gases substantially in a predetermined ratio, comprising the steps of: providing a first pyrotechnic charge capable of self-sustained burning for generating at least one component of said mixture; providing a second pyrotechnic charge not of itself capable of self-sustained burning for generating a component of said mixture; burning said first pyrotechnic charge; and maintaining said second pyrotechnic charge in thermal communication with said first pyrotechnic charge so that said second charge burns at substantially the same linear rate as said first charge.
