RESUMO
Open-loop response of the wake behind an actuator-equipped disk was experimentally investigated. The disk edge had flush-mounted tabs that moved radially in specified frequency and relative phase using electro-magnetic actuators. In spite of small amplitude of tab motion, significant modification of the helical mode of wake oscillation was observed.
