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. A centrifugal boost pump impeller section includes a plurality of impeller main blades, a plurality of primary splitter blades, and a plurality of secondary 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 another set of tables.
