ROTOR WITH ASYMMETRIC SPACING OF BLADES

摘要

A turbine apparatus that includes a rotor (30) with a hub section (32) defined about an axis of rotation (A) and a plurality of blades attached to the hub section (32). The plurality of blades comprises a first group having a first angular spacing (S1) in a first circumferential sector (38A) of the rotor (30), and a second group having a second angular spacing (S2) in a second circumferential sector (38B). of the rotor (30). The first angular spacing (S1) is different from the second angular spacing (S2), and the rotor blades are asymmetrical about the axis of rotation (A).
