Abstract

Recent demand for sustainable aviation design challenges aircraft manufacturers to reconsider existing technologies to address required cuts in environmental pollution. Key factors for new conceptual designs include the integration of unconventional distributed electric propulsion. To address the challenge of reliably predicting noise emissions, a simplified, fast and physical-principles based rotor noise model is introduced, with suitable adapted perturbation equations to represent current and possibly newly arising noise source mechanisms. Initial successful results of the implementation in the unstructured quadrature-free experimental Discontinuous Galerkin Computational Aeroacoustics solver DISCO++ of DLR are reported, outlining future possible applications.
