Abstract
A gas generator for generating a large volume of gases at moderate temperature in an extremely short time comprises a central combustion chamber containing a solid pyrotechnic charge and an ignition device therefor. The combustion chamber is laterally surrounded by a cooling chamber with which it communicates by means of apertures. In the cooling chamber combustion gases formed on ignition of the pyrotechnic charge are cooled by contact with at least one solid coolant material. The cooled combustion gases are discharged from the generator through apertures in the side wall of the generator which are disposed symmetrically with respect to the axis of the generator, so that when the combustion gases leave the generator they exert substantially no propulsive force on the generator.
