Abstract
A method of making an additively manufactured ejector pump includes creating a computer file defining the ejector pump in layers. The ejector pump includes a duct extending along a centerline from an upstream end to a downstream end, a nozzle extending inward from the duct including a flowpath, an annulus connected to the duct including a cavity. The method also includes building the ejector pump using an additive manufacturing process that builds the ejector on a layer-by-layer basis from the upstream end to the downstream end.
