Active Flow Control Devices
High Frequency Mechanical Piezo Amplifiers
drive vortex generator blades
FlexSys proprietary motion amplifiers are integrated with piezostack actuators to produce high frequency oscillations in micro vortex generators (VG) for active flow control applications. The resulting system is lightweight and consumes very low power for wide range of oscillation frequencies. Wind tunnel tests demonstrated the effectiveness of FlexSys system in delaying the flow separation and extending the operation lift range.
Piezo-compliant actuators create a static or oscillatory mechanical disturbance in the boundary layer, and are retracted flush with the control surface when not in use.
Active Vortex Generators for Lift Augmentation. US Patent 6,557,436, and others pending.
