Abstract:
An injector and combustion chamber assembly for mixing and delivering reactants including fuel and an oxidizer along with water into the combustion chamber, the assembly comprising in combination: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.
