Due to the tightening of the regulations on emitted sound and pollution in civil aviation, new aircraft concepts were recently investigated. Well-known examples are electric Vertical Take-off and Landing (eVTOL), aircraft equipped with distributed propulsion systems, and drones. The increasing complexity of this new generation of aircraft makes the accurate prediction of the aerodynamics and aeroacoustics performance a more challenging task. Existing high-fidelity tools excel at predicting such performance, but they require a high computational cost and time. Moreover, the current low-fidelity tools often show limitations when applied to complex configurations such as the distributed propulsion systems. Then, the scientific community is looking for new tools able to support every step of the design process of the more quieter and sustainable aircraft.
