摘要：
A compressor rotor airfoil (20) in a gas turbine engine is presented. Opposed pressure and suction sides (32,34) are joined together at chordally opposite leading and trailing edges (36,38). The pressure and suction sides (32,34) extend in a span direction from a root (25) to a tip (27). A leading edge dihedral angle (β) is defined at a point on the leading edge (36) between a tangent (T) to the airfoil (20) and a vertical (V). The leading edge dihedral angle (β) has a span-wise distribution. The distribution has at least one inflection point. A method of reducing a rub angle between a compressor rotor blade and a casing surrounding the blade is also presented.
