Abstract
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.
