Patent ID: 8807936

Claim:
A fan blade comprising: an airfoil section for rotation about an axis of rotation which defines an airflow passage therethrough, said airflow passage having an inducer section to receive an airflow from a first axial direction and turn said airflow to a radial direction; a diffuser section, within which air is diffused in communication with said airflow passage, wherein said diffuser section is radially outboard of said airfoil section, said diffuser section having a diffuser section center of mass positioned directly over said airfoil section, said diffuser section oriented to turn and split said airflow from said radial direction to a second axial direction, said second axial direction being substantially opposite said first axial direction; and a turning vane within said diffuser section, said turning vane within said diffuser section turning said airflow from a radial direction to said second axial direction.
