Abstract

A fan blade for a gas turbine engine includes an airfoil that has a first chord line that extends from a leading edge to a trailing edge. The first chord line is at 0% at the leading edge and at 100% at the trailing edge. The airfoil has a first local maximum thickness defined between about 85% of a span to a tip, a second local maximum thickness defined between about 40% to about 85% of the span and a third local maximum thickness defined between a root to about 40% of the span. The second local maximum thickness is positioned at about 10% to about 30% of the first chord line so as to be offset from the first local maximum thickness in the chordwise direction toward the leading edge. Each of the first, second and third local maximum thicknesses are different.
