Abstract
A fan blade assembly for a gas turbine engine includes a blade extending from a blade root to a blade tip, and from a blade leading edge to a blade trailing edge. The blade includes a plurality of ribs defining a plurality of blade cavities. A pressure surface cover is affixed to the blade and at least partially defines a pressure surface of the fan blade. At least one rib of the plurality of ribs extends along a predicted impact path of a foreign object at the fan blade assembly, thereby supporting impact loads on the pressure surface cover.
