    Abstract: Hollow fan blades (30) for turbo fan gas turbine engines are formed of two separate detail halves (30a;30b). Each detail half (30a;30b) has a plurality of cavities (40) and ribs (42) machined out to reduce weight. The floor (48) and opposite interior walls (50) of each cavity (40) are machined simultaneously. The configuration minimizes the number of cutter plunge cuts for the internal cavities, and maximizes cutter size, in order to minimize the time required to machine them. These detail halves (30a;30b) are subsequently bonded and given an airfoil shape in the forming operation.

    Abstract: A method for making a hollow fan blade includes the steps of: forming a plurality of ribs (42) on a first substrate (31), the first substrate (31) including cavities (40) on either side of each of the plurality of ribs; abutting the plurality of ribs (42) on the first substrate (31) with a second substrate (31) to form a hollow fan blade (30); and forming the hollow fan blade (30) into an airfoil shape while pressure inside the cavities (40) is substantially ambient pressure.
