Aeroacoustic Wind Tunnel
The NLR Aeroacoustic Wind Tunnel (NLR-AWT) is a state-of-the-art facility dedicated to researching the sources of aero-acoustic noise and developing techniques to reduce aircraft noise. Our research focuses on the early development phase (low Technology Readiness Level) or aims to improve existing systems. Additionally, we develop advanced measurement methods to identify and quantify noise sources. To gain a deeper understanding of complex airflows, we employ various flow measurement techniques, including Particle Image Velocimetry (PIV) with helium-filled soap bubbles and hotwire measurements, which enable us to map airflow patterns both qualitatively and quantitatively.
