Abstract:
1. A centrifugal boost pump inducer section comprising: a plurality of 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 cylindrical coordinates, wherein a Z-axis aligns with a rotational axis of the blades, an R coordinate corresponds to the distance from the Z axis and a theta coordinate is the relative angular position, said coordinates relative to a value D2 which corresponds to an impeller outer diameter, set out in one set of tables, TABLE 1-1 for the main blades and TABLE 1-2 for the splitter blades, or TABLE 2-1 for the main blades and TABLE 2-2 for the splitter blades, or TABLE 3-1 for the main blades and TABLE 3-2 for the splitter blades.
