Abstract
This paper presents an overview of noise prediction capabilities available at Dassault Systèmes and Delft University of Technology in the field of electric vertical takeoff and landing vehicle aeroacoustics. Three main aspects are covered: (i) noise source calculation via scale-resolving high-fidelity Lattice-Boltzmann flow simulations, (ii) noise propagation calculations in urban environments via Gaussian-beam tracing techniques, (iii) and flight mission analysis via a multi-fidelity model-based system engineering framework. Key features of the different numerical simulations techniques are discussed in more detail. Finally, a vision of a combined experimental/digital eVTOL noise certification process is outlined.
