The blade body defines a leading edge and a trailing edge. A first airfoil surface extends from the leading edge to the trailing edge A pocket is defined between the leading edge, the trailing edge, the blade root, and the blade tip. The pocket has a bottom surface that opposes the first airfoil surface across the blade body. The composite rib is disposed in the pocket. The cover is mounted to the composite rib and the blade body to form a second airfoil surface opposed to the first airfoil surface.

摘要： A gas turbine engine fan blade (34) having an airfoil portion (42) and a dovetail root portion (44) is enhanced by having spaced apart supporting ribs (65) extending into the dovetail root portion (44). The supporting ribs (65) define a plurality of hollow cavities (66) extending into the dovetail root portion (44) of the fan blade (34). The extended cavities (66) reduce the weight of each blade (34) and also improve the integrity of each blade (34).
