Throat distribution for a rotor and rotor blade having camber and location of local maximum thickness distribution

A rotor for a compressor, comprising:

• a hub;
• and
• a plurality of airfoils 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 plurality of airfoils coupled to the hub at the root and spaced apart from adjacent ones of the plurality of airfoils over the span by a throat dimension defined between the adjacent ones of the plurality of airfoils, the throat dimension has a maximum value at a spanwise location between 60% of the span and 90% of the span of the adjacent ones of the plurality of airfoils, the throat dimension between 90% of the span and the tip of the adjacent ones of the plurality of airfoils has a first value, and the throat dimension between the root and 10% of the span of the adjacent ones of the plurality of airfoils has a second value that is less than 60% of the maximum value.
