Abstract
A centrifugal impeller includes a pressurized cavity that reduce the stresses in the impeller disk, blades, shroud and hub as the stiffness of the rotor is not compromised while weight is reduced across the component and peak stress regions are shifted across the part. The centrifugal impeller can be a centrifugal pump or a radial inflow turbine. The pressurized cavity is formed between a forward wall and an aft wall of the impeller and can include a plurality of orifices that open into the cavity to supply pressure from low to high pressure location around the impeller. Annular rings can be used within the cavity to stiffen the impeller. Radial and tangential stiffening ribs can be used on the two walls to stiffen the impeller.
