Abstract
An apparatus is provided for a gas turbine engine. This engine apparatus includes an airfoil extending spanwise along a span line from a base to a tip. The airfoil extends laterally between a pressure side and a suction side. The airfoil extends longitudinally along a camber line from a leading edge to a trailing edge. The airfoil includes a first section and a second section arranged longitudinally between the first section and the trailing edge along the camber line. An angle between the camber line and a reference plane changes according to a slope as the airfoil extends longitudinally along the camber line. The slope in the second section is greater than the slope in the first section.
