摘要

A method of forming a blade comprising the steps of forging a part (10) comprising a suction side (21), a pressure side (23), and a dividing portion (25) of material greater than a portion of material to be sacrificed between the suction side (21) and the pressure side (23), splitting the part (10) through the dividing portion (25) of material to form a suction side inner surface (33) and a pressure side inner surface (33), and joining the suction side inner surface (33) and the pressure side inner surface (33) to form the blade.
