Abstract:
1. An airfoil for a compressor comprising: an airfoil root, an airfoil tip located at a spanwise distance from the airfoil root, a leading edge extending from the airfoil root to the airfoil tip, a trailing edge extending from the airfoil root to the airfoil tip, airfoil pressure and suction sides extending between the leading edge and the trailing edge; an inner span region (“S 1 ”) between the airfoil root and a first height location on the airfoil leading edge; a midspan region (“S 2 ”) between the first height location and a second height location on the airfoil leading edge located radially outward from the first height location; an outer span region (“S 3 ”) between the second height location and the airfoil tip; and wherein the airfoil has a normalized camber profile 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.
