A fan blade includes an airfoil having opposite pressure and suction sides extending in span between a root and tip, and extending in chord between opposite leading and trailing edges. From root toward tip, the airfoil includes increasing stagger and decreasing camber, and increasing chord length to barrel the airfoil along both the leading and trailing edges. The airfoil further includes forward aerodynamic sweep at the tip, and non-forward aerodynamic sweep between the maximum barrel and the root.
Accordingly, what is desired to be secured by Letters Patent of the United States is the invention as defined and differentiated in the following claims in which we claim: 1. A gas turbine engine fan blade comprising: an airfoil extending outwardly from a sloped root and including opposite pressure and suction sides extending longitudinally in span from said root to an opposite tip, and extending axially in chord between opposite leading and trailing edges; said airfoil further including stagger increasing between said root and tip, camber decreasing th...
