Abstract:
A gas turbine engine has a fan section including a fan hub supporting a plurality of fan blades for rotation relative to a fan case. A shaft is rotatable relative to the fan case about an engine center axis. A geared architecture is driven by the shaft and provides driving output to rotate the fan hub. A compressor is driven by the shaft and is positioned forward of the geared architecture. The compressor includes at least first and second stages with the first stage being positioned forward of the plurality of fan blades and the second stage being positioned aft of the plurality of fan blades. The compressor includes at least one set of vanes that rotate in a first direction about the engine center axis and at least one set of compressor blades that rotate in a second direction about the engine center axis. The second direction is opposite of the first direction.
