Experiments were conducted to determine the ability of the Wiener deconvolution method to reconstruct an unsteady surface pressure on a pitch-oscillating airfoil using a remotely sensed pressure signal. The method’s ability to reconstruct signals distorted through attenuation and resonance effects were examined for different lengths of 0.86mm diameter tubing. Five different lengths of tubing (30 cm through 152 cm) were tested in a bench-top setting. In addition, the effects of real pressure port geometries were considered using the pressure ports in the airfoil section. Finally, the Wiener deconvolution method was used to estimate the time-dependent pressure while the airfoil oscillated in pitch at 5 and 10 Hz in a wind tunnel. The results demonstrated that the Wiener deconvolution method was very effective for correcting the remotely measured pressure signals for all the cases studied. The calibration effort necessary for applying the Wiener deconvolution method was modest making the approach suitable for practical testing situations.
