Abstract
Official abstract text for this publication.
A disclosed centrifugal boost pump volute includes normal to flow cross sectional surfaces distributed over the length of the passage. The volute includes a volute proper, an exit bend and a diffuser fluidly interconnecting the volute proper to the exit bend. The cross sectional surfaces are defined as dimensions set out in one set of data, which includes Tables N-1 and N-2 for the volute proper and Table N-3 for the volute exit bend, where N is the same value.
