Abstract

A composite blade includes a composite airfoil section having airfoil pressure and suction sides extending chordwise between airfoil leading and trailing edges, a dovetail root attached to airfoil section and a blade shank therebetween, and a metallic leading edge shield covering an axially extending portion of airfoil section including at least a portion of airfoil leading edge and a radially and chordwise extending portion of a leading edge portion of the blade shank. Leading edge portion may be cut back from airfoil leading edge and a shank leading edge aft or downstream of airfoil leading edge. A nose may extend along a shield leading edge of the metallic leading edge shield with pressure and suction side legs extending aftwardly from nose along airfoil pressure and suction sides. Light weight insert may be located between nose and airfoil leading edges.
