Abstract
An inducer that includes a profiled throat. In some embodiments, the inducer includes a conical shape upstream of the profiled throat with a relatively large circular inlet that narrows to the profiled throat and, downstream of the profiled throat, a downstream section that broadens from the profiled throat. The profiled throat may include an approximate convergent-divergent nozzle geometry.

An inducer that includes a profiled throat, wherein the inducer is a radial-axial inducer and is configured to direct and accelerate a flow of cooling gas in a gas turbine engine;
- the inducer comprises a conical shape upstream of the profiled throat with a relatively large circular inlet that narrows to the profiled throat and, downstream of the profiled throat, a downstream section that broadens from the profiled throat.
