This paper contributes to the development of two different open/closed-loop strategies for actively control wing aerodynamic stall by means of coordinated arrays of synthetic jet actuators. The control of the flow over aerodynamic shapes in order to achieve performance enhancements; such as improved aircraft maneuverability; has been a lively area of research for the last two decades. Active flow control can produce significant performance improvement when combined in a closed-loop control system. Synthetic jet actuators (SJAs) are devices able to interact actively with the flow around a hosting structure by providing ejection and suction of fluid from an orifice. The research presented in this paper concerns the implementation of Zero-Net-Mass-Flux SJAs airflow control system on a NACA0015 low aspect ratio (LAR) wing section prototype developed by Clarkson University under the Advancement of Intelligent Aerospace Systems (AIAS) AFOSR Grant FA9550-09-1-0051. Wind tunnel experiments; on the uncontrolled wing; are primarily performed for system identification purpose. The open-loop control of the wing is implemented and tested; obtaining a stall delay of about 2.8 degrees of angle of attack. A strategy based on the comparison of several acoustic pressure sensors PSD profiles is adopted to characterize the forthcoming boundary layer detachment. This allows for triggering the closed-loop control in stall proximity only for sake of energy optimization. Pertinent results and discussion will be provided;
