Active Flow Control of a High-Lift Supercritical Airfoil with Microjet Actuators

What is it about?

Active flow control (AFC) has the potential for substantial performance gains and meeting the challenges of next-generation air vehicles. High-lift airfoils employ trailing edge flaps during takeoff and landing and stowed during the cruise. The present experimental investigation was carried out to examine the active flow control effectiveness on the NASA Energy Efficient Transport (EET) airfoil fitted with a simple hinged flap. Microjet control is able to completely re-attach the flow at both flap deflection angles and significantly reduce the airfoil drag.
