Abstract
A fan blade (20) has a main body (28) extending between a leading edge (21) and a trailing edge (22). Channels (30) are formed into the main body (28) from an open side extending toward an opposed closed side. A plurality of ribs (26) extending across the main body (28) intermediate the channels (30), the fan blade (20) has a dovetail (24), and an airfoil (18) extending radially outwardly from said dovetail (24). A bottom surface of the channels (30) is defined at the closed side of the channels (30). Sides (34) of the channel merge into sides (36) of the ribs (26), with a compound fillet at the bottom surface. A first radius of curvature (r 2 ) is used along the bottom and merges into at least a second radius of curvature (r 3 ) at the sides (36). The first radius of curvature (r 2 ) is larger than the second radius of curvature (r 3 ).
