Abstract

The impedance of the nacelled at the resonance condition is measured at nine points using an impedance tube. Using the same nacelle nine points, specimens are cut and the airflow resistance measured using the ASTM C522. The results indicate that the proposed method provide an alternate non-destructive for measuring the air flow resistance of materials.
