Abstract

A centrifugal boost pump inducer section includes a plurality of inducer main blades, and a plurality of splitter blades, each of which includes normal to the blade mean line cross sectional surfaces distributed over the length of the blades, the cross sectional surfaces defined as a set of R-coordinates, theta-coordinates and Z-coordinates relative to an impeller outer diameter set out in one set of tables.
