Abstract: ABSTRACT A hybrid active-passive flow control system integrates an active boundary layer control mechanism, applying suction or injection at 50% to 70% of the chord length, with a passive Gurney flap mounted perpendicularly at the trailing edge pressure surface. The active mechanism removes low-momentum boundary layer fluid to maintain attached flow, while the Gurney flap generates counter-rotating vortical structures to enhance circulation. Numerical evaluation using Reynolds- Averaged Navier-Stokes equations with k-omega SST modeling shows the hybrid configuration achieves a 45% lift coefficient improvement and a 14% stall angle increase over a baseline airfoil, yielding lift enhancement 124% higher than Co-Flow Jet configurations. The invention applies to aircraft wings, wind turbine blades, UAVs, helicopter rotors, and compressor blades under subsonic and transonic conditions.
