This water channel allows to investigate the influence of wake depressions and choking to a stator cascade. Furthermore, adaptive blade systems are presented to affect the operating of stator under periodic unsteady flow conditions. The piezoelectric actuators are one of these adaptive blade systems. These can adjust the profile, so that the stator is more efficient than without.enadaptive blade systemsstator cascadepiezoelectric actuatorConference Object
