AERIALIST

The EU-funded AERIALIST project identified and developed breakthrough technologies based on metamaterials to achieve noise reduction targets outlined in the ACARE Flightpath 2050 strategy, Europe’s vision for aviation. Metamaterials can be defined as materials engineered to attain a response not available in nature and are typically characterised by a recurring structure at the macro or micro scale.

Consortium members built on current acoustic metamaterial theory by studying the effect of realistic aerodynamic flows to develop numerical methods that simulate the behaviour of acoustic metamaterials under aircraft operating conditions. AERIALIST also assessed the technical feasibility of noise reduction devices based on the concepts developed, proposing a roadmap towards their practical realisation.
