Keywords: Aerodynamic noise, Phased-array, Low-speed wind tunnel, High-lift device

In order to obtain aeroacoustic data and aerodynamic data simultaneously, aeroacousitc measurements with phased-array microphones in closed test sections of 2m x 2m and 6.5m x 5.5m aerodynamic low-speed wind tunnels had been conducted. Measurement results of a NACA0012 model, high-lift device models, and so on, are discussed.
