This thesis explores the mitigation of artificial wind gust effects on the lift coefficient of a DLR-F15 airfoil using dynamic trailing-edge flap scheduling in a wind tunnel. Atmospheric turbulence, particularly wind gusts, has long been a concern in aviation, with documented incidents leading to aircraft losses. Active mitigation strategies promise enhanced safety, passenger comfort, and reduced costs through weight savings. The experiments are conducted at high Reynolds numbers, flow speeds, and flap motion rates, utilizing an electric servomotor for dynamic flap actuation. The lift coefficient is calculated from precise surface pressure measurements along the airfoil's mid-span, with both steady and high-frequency time-resolved data collected. Artificial gusts are created upstream using rapid pitching motions of a NACA-0021 airfoil. Real-time control of the lift coefficient is achieved through a combination of feedback and feedforward mechanisms based on disturbance measurements from a hot wire anemometer. The dynamic characteristics of the system components are analyzed and modeled prior to control experiments. The lift response to unsteady flap actuation is examined under sinusoidal flap motions of varying rates and amplitudes. The findings provide insights into the aerodynamics of rapidly deflected control surfaces. Two models—nonlinear and linear—are calibrated to reflect lift coefficient responses to flap motions and m
