Development of New digital Microphone-MEMS-Sensors for wind tunnels with open/closed test sections and flight tests

The main objective is to develop a novel technology for surface unsteady pressure measurements which are suitable for arbitrary model/aircraft position (including cockpit area) and with high spatial resolution. State of the art microphones are too large to capture the unsteady pressure fluctuations underneath the turbulent boundary layer to predict the cabin noise excitation (especially in regions with high pressure gradients). MEMS sensors seem to be a good candidate to overcome. State of the art microphones limitations. This topic aims at developping new digital MEMS based microphones fulfilling acoustic requirements for wind-tunnels and flight test applications. Please refer to the full topic descriptions document published in this call.
