Kurzfassung
The high-lift system noise is predicted for a landing approach condition for the actual scale Airbus 320-232 “D-ATRA” research aircraft of DLR. Noise simulations are performed for all key elements of the high-lift wing using stochastically derived sources, based on the underlying one-off Reynolds-Averaged Navier–Stokes CFD simulation. Turbulence quantities that are essential for the acoustic source characterisation are derived from the CFD solution by means of eddy viscosity. The acoustic perturbation equations (APE) are solved in close proximity to the aircraft using a volume-resolving discontinuous Galerkin method, valid in a non-uniform medium, assuming uncorrelated source domains.
