THROAT DISTRIBUTION FOR A ROTOR AND ROTOR BLADE HAVING CAMBER AND LOCATION OF LOCAL MAXIMUM THICKNESS DISTRIBUTION

A rotor (200) for a compressor includes a hub and a plurality of airfoils (200) having a root, a tip opposite the root and a span that extends from 0% at the root to 100% at the tip. Each of the airfoils is coupled to the hub at the root and is spaced apart from adjacent ones of the airfoils over th...

Beschreibung
Zusammenfassung:	A rotor (200) for a compressor includes a hub and a plurality of airfoils (200) having a root, a tip opposite the root and a span that extends from 0% at the root to 100% at the tip. Each of the airfoils is coupled to the hub at the root and is spaced apart from adjacent ones of the airfoils over the span by a throat dimension. The throat dimension has a maximum value (246) at a spanwise location between 60% of the span and 90% of the span of the adjacent ones of the airfoils, and at 10% of the span of the adjacent ones of the airfoils above or below the spanwise location of the maximum value, the throat dimension (248,250) is less than 97% of the maximum value. The throat dimension (244) at 5% of the span of the adjacent ones of the airfoils is less than 70% of the maximum value.
