HIGH CAMBER COMPRESSOR ROTOR BLADE

摘要

A rotor blade (104) having an airfoil (10) for a compressor is described. The airfoil has an airfoil root (11), an airfoil tip (12) located at a spanwise distance from the airfoil root, a leading edge (20) extending from the airfoil root to the airfoil tip, an inner span region (13, S2) between the airfoil root and a first height location (41) on the airfoil leading edge, a midspan region (23, S2) between the first height location and a second height location (42) on the airfoil leading edge located radially outward from the first height location; an outer span region (14, S3) between the second height location and the airfoil tip, wherein the airfoil has a normalized camber profile (120) such that the normalized camber increases in the outer span region in a spanwise direction towards the tip and is more than 2.2 in the outer span region.
