Project description
High-performance miniaturised sensors for aeroacoustic measurements
The EU-funded AEROMIC project targets the development of innovative sensor technology for aeroacoustic measurements based on high-performance microelectromechanical system (MEMS) microphones and a compact smart sensor surface. The piezoelectric and piezoresistive MEMS microphones will demonstrate superior properties in terms of bandwidth, sensitivity, dynamic range and robustness compared to state-of-the-art systems. They will be used to capture the unsteady pressure fluctuations underneath the turbulent boundary layer and for wall shear stress measurements in next-generation large passenger aircraft. Their designs will be optimised for wind-tunnel testing and flight testing applications.
Objective
AEROMIC aims at envisioning an innovative sensor technology for aeroacoustic measurements based on high performance MEMS microphones integrated as microphone arrays, and the development of a compact smart sensor surface through the integration of sensors and electronic components using vertical integration technology. The main objective of this proposal is the development of novel high performance digital wall-mounted microphone-MEMS-sensors for surface unsteady pressure and wall shear stress measurements for future noise reduced large passenger and other aircrafts. Novel miniaturized piezoelectric and piezoresistive MEMS microphones with properties exceeding the state-of-the-art in terms of bandwidth, sensitivity, dynamic range and robustness will be developed to capture the unsteady pressure fluctuations underneath the turbulent boundary layer with very high spatial and temporal resolutions in a very broad frequency range. The two MEMS microphones can be optimized for the wind-tunnel testing (WTT) and flight testing (FT) applications as required, respectively.
