Claim 16:
17. The rotating airfoil assembly of claim 16, wherein the at least one opening is located on the suction surface, and
wherein the controller is configured (i) to receive an indication that the rotation axis of the rotating airfoil assembly is angled one of upward or downward relative to the direction of an airflow into the rotating airfoil assembly, (ii) to operate the flow control valves to supply air to the at least one opening in each rotating airfoil that is rotating in an upward direction in response to an indication that the rotation axis of the rotating airfoil assembly is angled upward, and (iii) to operate the flow control valves to supply air to the at least one opening in each rotating airfoil that is rotating in a downward direction in response to an indication that the rotation axis of the rotating airfoil assembly is angled downward.
