Abstract

A fan blade (20) for a gas turbine engine includes a main body (28) that extends between a leading edge (21) and a trailing edge (22). The main body (28) includes channels (30) formed into the main body (28) and a plurality of ribs (26) extending between the channels (30) and a ledge. The ledge is formed as an integral part of the main body (28) and is configured to define an outer perimeter the channels (30). A cover skin (32) is formed on and metallurgically bonded to the main body (28), including the ledge and the plurality of ribs (26) of the main body (28) using a hybrid additive manufacturing/subtractive manufacturing process. The cover skin (32) is configured to cover (32) the channels (30) and form an aerodynamic surface. The main body (28) and cover skin (32) form an airfoil (18) that extends radially outwardly from a dovetail, which is configured to permit the fan blade (20) to be attached to a fan rotor (16) of the gas turbine engine (210).
