ERC Grant awarded to Daniele Ragni for research on predicting aeroacoustics

News - 08 April 2024

The European Research Council (ERC) has announced that Daniele Ragni will receive an ERC Consolidator Grant for his research on noise caused by the interaction of rotors with airframe components. The ERC Consolidator grant is aimed at researchers with 7 to 12 years of post-PhD experience and spans a duration of five years, providing ample support for groundbreaking research endeavors.

Reducing aircraft noise

Daniele Ragni's project, titled "MORASINA" (Modelling Rotor Aircraft Surface Interaction Noise for Acoustic Prediction), aims to more accurately predict, and subsequently reduce, noise caused by interacting aircraft components. Climate neutral aviation has led to an increase in size of new propulsion systems, resulting in closer proximity between rotating components and airframe structures. As a result, conventional acoustic models now wrongly predict interaction noise sources, by more than 10 dB.

Correctly predicting and further eliminating interaction noise enables the deployment of new aircraft configurations, reducing more than 15% of the current aviation emissions.

To improve these acoustic models, the first step is to develop a comprehensive mathematical framework that encapsulates the intricate flow distortions between rotating and stationary objects. This formula will help to better understand how various aircraft components interact with each other when generating noise. Subsequently, the project seeks to integrate this mathematical framework into a robust aeroacoustic prediction model, paving the way for more accurate and reliable noise prediction methodologies.

"This grant provides crucial support for the success of the MORASINA project, which in return can hugely impact the project eVTOLUTION, the Horizon Europe project I am working on together with the von Karman institute for Fluid Dynamics in Belgium". The eVTOLUTION project aims to accelerate the development and certification process for innovative aircraft concepts, focusing on electric ‘vertical take-off and landing’ aircraft for urban and suburban areas.

While the grant primarily focuses on Ragni's individual research efforts, collaboration with Prof. Damiano Casalino and industry partner 3DS Dassault Systemes will further enrich the project's outcomes. Anticipated outcomes from the project are expected to materialize within the coming year, underscoring the project's timeliness and relevance.
