TECHNICAL ABSTRACT ( Limit 2000 characters, approximately 200 words)
Active flow control to prevent or delay boundary layer separation dramatically improves the performance of air vehicles in critical regions of the flight envelope. FlexSys Inc. has designed a compact, efficient, electromechanical High-Frequency Micro-Vortex Generator system (HiMVG) and tested it a subsonic speeds, proving that, when tuned to the boundary layer, it is as effective at promoting flow attachment as that of the best oscillatory pneumatic systems but is light-weight and energy-efficient, consuming a maximum 6 watts of power per actuator. We propose to enhance the HiMVG system by further reducing its power consumption, increasing its maximum oscillating frequency, and demonstrating its effectiveness at transonic speeds. The proposed system will have a tunable natural frequency, so that as the flow velocity changes, we can adjust the HiMVG system's natural frequency to match the optimal vortex generator frequency, allowing us to maintain nearly constant, ultra-low-power consumption. This will allow effective flow control for diverse flight conditions. The system will consume very little power - less than one watt per actuator - allowing large arrays to operate using light-weight, compact power supplies. These improvements will make the HiMVG system feasible for a wide variety of situations where active flow control is necessary, from subsonic through transonic conditions.

POTENTIAL NASA COMMERCIAL APPLICATIONS ( Limit 1500 characters, approximately 150 words)
Robust, light-weight, energy-efficient active flow control devices can be applied to a wide variety of aircraft on wings, fuselages, at inlet ports of turbine engines, etc. Potential NASA customers for our HiMVG system include the Fundamental Aeronautics Program within the Aeronautics Research Mission Directorate.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS ( Limit 1500 characters, approximately 150 words)
Robust, light-weight, energy-efficient active flow control devices can be applied to a wide variety of aircraft on wings, fuselages, at inlet ports of turbine engines, etc. Potential Non-NASA customers for our HiMVG system include all branches of the military, and all of the major aircraft and jet engine manufacturers.
