A propulsive power-producing system has a vessel defining a pressure chamber and an injector and a thrust-producing nozzle communicating with the chamber at respective upstream and downstream ends of the vessel. A dual catalytic/thermal gas generator housed in the vessel chamber includes a catalyst bed enclosed by a sleeve, a bedplate and the upstream vessel end. The sleeve is spaced inwardly from the side of the vessel to define an annulus therebetween. When a propellant liquid is injected under pressure through the injector into the catalyst bed, a first fraction of the liquid flows along a first path which leads through the bed and concurrently is catalytically decomposed into a first fraction of propellant gas which exits through openings in the bedplate into a mixing passage which leads to the nozzle. A remaining fraction of the liquid overflows along a second path which leads through orifices in the sleeve into and through the annulus and concurrently is thermally decomposed therein by contact with the heated sleeve into a second fraction of propellant gas. The second gas fraction exits through holes in the bedplate and into the passage wherein it mixes with the first gas fraction before exiting through the nozzle.
