Abstract

See full text

Compressor wheel (16) and techniques for manufacturing such a wheel are provided. The wheel may include a hub (21) with a counterbore (36) internally treated to impart residual compressive stresses, for enhanced endurance to stress-induced fatigue. The surface treatment allows extending the counterbore relatively closer to a plane (30) of typical maximum stress of the wheel. This design flexibility advantageously allows avoiding or reducing overhang of the compressor wheel, thereby improving rotor dynamics and reducing the axial length of the hub, and the overall foot print of the compressor wheel.
