초록 ▼

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.

대표청구항 ▼

A gas generator for producing a large volume of gases at moderate temperature in an extremely short time, stable during firing, which comprises an essentially cylindrical casing closed at its ends by two substantially circular plates, a cylindrical partition coaxial with said casing dividing the space within said casing into a combustion chamber containing a pyrotechnic charge and an ignition device therefor and a cylindrical cooling chamber completely surrounding the combustion chamber and adapted to contain at least one solid material for cooling the gases produced on ignition of the pyrotechnic charge, first orifices between the cooling chamber and the combustion chamber to allow passage of the combustion gases from the combustion chamber to the cooling chamber, said orifices being located essentially at both ends of said partition, second orifices arranged radially in the wall of the casing to permit discharge of the combustion gases which have passed through the cooling chamber, a homogenization space in the combustion chamber located above and below said pyrotechnic charge, the second orifices in the wall of the casing being disposed symmetrically with respect to the aXis of the casing.
