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 therebetween, and chord length increasing outboard from said root to barrel said airfoil along both said leading and trailing edges; and
said airfoil includes maximum forward aerodynamic sweep at said tip transitioning to maximum aft sweep inwardly along said leading edge in said barrel, and decreasing in aft magnitude to non-forward sweep at said root.
