Temperature-Activated Change of Permeable Material Properties for Low-Noise Trailing Edge Applications

The present work analyses broadband noise scattering from permeable trailing edges with identical micro-structure but under a change of temperature. Experiments are performed in an anechoic wind tunnel using a NACA0018 airfoil at chord-based Reynolds numbers between 1.88 &#215; 10<sup>5<...
