Abstract (en)
The buckets (20) of a turbine wheel (10) are formed as a series of equally spaced, overlapping portions of a cylinder in the grooved rim of a wheel forging. As a result of this construction, the leading edge of the buckets (20) is eliminated and is therefore not subject to 90 DEG erosion. Additionally, the resulting bucket profiles result in very low impingement angles for moisture droplets or particulates which further minimizes low angle erosion.
