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

Active flow control 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, which are stowed during cruise. The present experimental investigation was carried out to examine the active flow control effectiveness on the NASA Energy Efficient Transport airfoil fitted with a simple hinged flap. Experiments were carried...
