Abstract
A blade or vane includes a platform 130 and an airfoil 132 extending from the platform. The airfoil has a pressure surface offset in a first direction D1 from a part span mean camber line 148, a suction surface offset in a second direction D2 from the part span mean camber line, and a base 146 that is laterally enlarged in the first direction for reducing secondary flow losses.
