Abstract
A radial flow turbine wheel comprises a disc, a spindle and blades, each blade having a curved surface configuration in symmetry with respect to a plane which is normal to the spindle and which passes through a mid portion of the axial length of the disc, thereby eliminating the creation of a net axial thrust force caused by an imbalance of the axial component forces of gas flow acting on the blades.
Claims4
In a radial flow turbine wheel wherein a plurality of blades extend radially outwardly from a central disc having a spindle extending axially therethrough, and wherein gas received radially between inlet portions of said blades is progressively deflected to escape axially from between outlet portions of said blades, the improvement comprising:
- said blades being supported solely by said disc, with the maximum radial dimension of said disc being spaced radially inwardly from the inlet portions of said blades;
- and
- each of said blades having a curved surface configuration which is symmetrical with respect to a plane normal to said spindle and which passes through a mid-portion of the axial length of said disc, the outlet portions of said blades being both spaced radially inwardly from as well as offset axially from said inlet portions.
