Abstract

A fan blade (50, 450) comprising a root end, a blade region and a transition region. Wherein each of the root end (52, 452) and blade region comprise a unique profile, and wherein the transition region comprises a profile which transitions the root end (52, 452) profile to the blade region profile. The root end profile comprises a substantially convex top surface, a substantially concave domed sector, and reliefs to allow for the root end (52, 452) to be coupled with a similarly shaped fan hub extrusion. The blade region profile comprises a substantially convex top surface (102, 202, 302) and bottom surface (104, 204, 304) which terminate at a leading edge (80, 106, 206, 306, 480) and trailing edge (90, 108, 208, 308, 490). The blade region slopes upward along a length of the blade region and terminates at a curved tip.
