Abstract:
Provided herein are various improvements to rocket engine components and rocket engine operational techniques. In one example, a rocket engine propellant injection apparatus is provided that includes a manifold formed into a single body by an additive manufacturing process and comprising a fuel cavity and an oxidizer cavity. The manifold also includes one or more propellant feed stubs, the one or more propellant feed stubs protruding from the manifold and formed into the single body of the manifold by the additive manufacturing process, with at least a first stub configured to carry fuel to the fuel cavity and at least a second stub configured to carry oxidizer to the oxidizer cavity. The manifold also includes a plurality of injection features formed by apertures in a face of the manifold, ones of the plurality of injection features configured to inject the fuel and the oxidizer for combustion.

Claim (Index 1):
A rocket engine injector apparatus, comprising:\n an injector body formed by an additive manufacturing process; a fuel cavity in the injector body; an oxidizer cavity that forms a generally toroidal shape around the fuel cavity; feed stubs formed into the injector body by the additive manufacturing process, the feed stubs comprising tube structures projecting outwards from a first face of the injector body and having swaged or flared features to mate with compression-type fittings in a metal-to-metal seal for attachment to associated feed lines; wherein at least a first feed stub extends outward from a first position of the first face of the injector body and is configured to carry fuel through a first channel to the fuel cavity; wherein at least a second feed stub extends outward from the first face of the injector body in a position offset from the first position and is configured to carry oxidizer through a second channel to the oxidizer cavity; and a plurality of injection apertures in a second face of the injector body opposite the first face of the injector body configured to inject the fuel and the oxidizer for combustion, with each of the fuel cavity and the oxidizer cavity feeding a corresponding subset of the injection apertures.
