Aeroacoustics in windtunnels

Windtunnels are typically used to develop and confirm aerodynamic designs at a significantly reduced cost compared to full-scale flight-testing - but they are also used for aeroacoustic measurements in hydro, laminar or turbulent flows.

As an R&D engineer you need reliable data and the only way of achieving that is stable measurements based on reliable microphones. That’s why GRAS offers an aeroacoustic toolbox for your wind tunnel testing, including a wide range of acoustic sensors and rugged measurement microphones designed to endure the demanding requirements of extreme aerospace testing in the aerospace and defense industry.
