  • Publication number: 20130078103
    Abstract: A fan blade has a main body extending between a leading edge and a trailing edge. Channels are formed into the main body from at least one open side. A plurality of ribs extend across the main body intermediate the channels. The fan blade has a dovetail and an airfoil extending radially outwardly from the dovetail. The ribs have a thickness defined as measured generally from the leading edge toward the trailing edge. A thickness of at least one of the ribs is generally thicker adjacent radially inner ends and becomes thinner moving in a radially outward direction.
