Abstract:
1. An injector assembly for a rocket engine, the injector assembly comprising: a faceplate positioned adjacent to a combustion chamber that defines an engine centerline; a first set of holes defined in the faceplate; a first set of injector elements, wherein the first set of injector elements is arranged to correspond with the first set of holes defined in the faceplate such that each injector element is positioned to extend into one of the first set of holes, and wherein an annular fluid outlet is formed between each injector element and each hole in the faceplate for delivering a first fluid to the combustion chamber; a first injector manifold, wherein each injector of the first set of injector elements is connected in fluid communication with the first injector manifold for delivering a second fluid to the combustion chamber; a second set of holes defined in the faceplate; a second set of injector elements, wherein the second set of injector elements is arranged to correspond with the second set of holes defined in the faceplate such that each injector element is positioned to extend into one of the second set of holes, and wherein an annular fluid outlet is formed between each injector element and each hole in the faceplate for delivering the first fluid to the combustion chamber; and a second injector manifold, wherein each injector of the second set of injector elements is connected in fluid communication with the second injector manifold for delivering a third fluid to the combustion chamber.
