A system and method is provided in the form of an injector assembly 10 for thoroughly premixing fuel and oxidizer reactants and water upstream of a combustion chamber 12. The assembly includes a housing 20 that has a first stack 30 for thoroughly mixing reactants from an oxidizer source 40 and a fuel source 50. It also includes a second stack 80 for mixing and blending the prior mixed reactants with coolant water, before ignition within a combustion chamber 12. The mixing and blending is accomplished in mixing cups 100 where the water and reactant mixture are joined in perpendicular flow streams. Some water is also introduced tangentially in the mixing cups to promote vortical flow and further enhance the mixing process. An alternative injector assembly 210 is also provided that mixes the reactants in a swirl cup 260 and enhances mixture ratio uniformity by means of a diffusion plate insert 270.

[What is claimed is:] [1.]a fuel inlet coupled to a source of fuel;an oxidizer inlet coupled to a source of oxidizer;a water inlet coupled to a source of water;a face oriented adjacent the combustion chamber and facing the combustion chamber, said face including at least one outlet for a mixture of the fuel, the oxidizer and the water;a mixer for the fuel, the oxidizer, and the water, said mixer located upstream from said outlet;said face located between said mixer and said combustion chamber;wherein said mixer includes multiple separate fuel pathways located downstream from said fuel inlet, each said fuel pathway leading to a separate fuel outlet, and multiple separate oxidizer pathways located downstream from said oxidizer inlet, each said oxidizer pathway leading to a separate oxidizer output, said fuel outlets and said oxidizer outputs oriented to discharge the fuel and the oxidizer into a common mixing region;wherein said common mixing region for the fuel and the oxidizer is located upstream from said water inlet, such that the fuel and the oxygen are mixed together first before the water is mixed with the fuel and the oxidizer by said mixer; andwherein said multiple separate fuel pathways are located within a series of planar fuel platelets and wherein said multiple separate oxidizer pathways are located within a series of planar oxidizer platelets, said fuel platelets stacked in an alternating arrangement with said oxidizer platelets.
