Abstract
A stage of a fan for a gas turbine engine may include a rotor blade and a stator vane disposed aft of the rotor blade. A baffle may be coupled to the stator vane. The baffle may define a secondary airflow path from aft of the stator vane to forward of the rotor blade. The baffle may further define the secondary airflow path from aft of the stator vane to forward of the stator vane.
