ABSTRACT:
A gas generator for passing pressurized liquid monopropellants therethrough or causing exothermic decomposition of the monopropellants. A porous catalytic metal plate is used as the degeneration bed. The monopropellant decomposes exothermically upon contact with the catalytic plate. The porosity is obtained by making the plate from an alloy of the catalyst metal and one other metal, the other metal is then etched away by an acid that does not attack the catalyst metal. The porosity is controlled by the amount of other metal used. Surface areas of several hundred times the original plate surface area are obtainable. The mechanical characteristics of the metal plate allow for greater design flexibility than was available with decomposition beds made of refractory material.
