In this presentation, active flow control (AFC) in the form of microjets are considered on the flaps of the high-lift version of the Common Research Model (CRM-HL). Microjets provide circulation control using small surface-normal pneumatic jets located near the trailing edge of a lifting surface such as a wing or flap. When located on the pressure side of the lifting surface they increase the lift, and when located on the suction side they decrease lift. Two different architectures to supply the air for the microjets are considered: (1) bleed air from the airplane's auxiliary power unit (APU) plus ram air, and (2) engine fan bleed air plus ram air. The results of this study are encouraging in that pressurized air from the APU or the engine fan can be used to entrain ram air and thereby increase the AFC mass flow rate to achieve effective lift control and airplane performance enhancement during takeoff and landing.
