Air blown through small holes in the blade makes dynamic stall less severe in demanding maneuvers, according to researchers at DLR.

Researchers at the German Aerospace Center (DLR) in Göttingen may have discovered a way to make helicopters more maneuverable, by reducing the dynamic load on the rotor head control rods.

During rapid forward flight or maneuvering, airflow stalls on the main rotor blade as it retreats (moves backwards), giving rise to a “dynamic stall” and subjecting the rotor head control rods to formidable dynamic loads.
