dc.description.abstract	An experimental investigation of the unsteady pressure measurement of a 2D NACA 0018 airfoil oscillating in pitch motion was performed by using pressure transducers at open-circuit wind tunnel. In the case of study, the wind tunnel testing was conducted in low flight regimes (𝑅𝑒 = 68474 and 𝑅𝑒 = 136948) at various angles of attack. Static test was performed and the data were obtained as baseline for further analysis. Surface pressure over the lower and upper surfaces of the airfoil was measured and was subsequently used to compute the pressure coefficient. With regard to analysis purpose, for static test, the graphs of pressure coefficient against 𝑥/𝑐 of 2°, 12° and 18° angle of attack at free-stream velocities of 5 𝑚/𝑠 and 10 𝑚/𝑠 were plotted whereas for dynamic test, the 3D representations of pressure distribution with 𝑥/𝑐 and time for pitching amplitude of 5°-15° and 10°-20°, pitching frequency of 3 𝐻𝑧 and free-stream velocities of 5 𝑚/𝑠 and 10 𝑚/𝑠 were plotted.	en_US
