The accurate prediction of helicopter blade vortex interaction (BVI) noise by numerical methods still poses a challenge, as it requires the exact determination of the aerodynamic flow field around the rotor blades, especially the accurate capturing of the blade tip vortex strength and trajectory. Moreover high fidelity turbulence modeling for instance LES schemes as well as the precise determination of the fluid structure coupling is important for the noise prediction. However main focus of this work is on the development of a standalone, higher-order flow solver on Cartesian grids, called Cartesian TAU. Global objective is creating an infrastructure for coupling C artesian TAU with the unstructured DLR-TAU-Code via a Chimera-based interface using the inherent advantages of each meshing paradigm. First results of an inviscid convection of a vortex in a uniform free stream will be demonstrated. This work is done in cooperation with the DLR and the University of Stuttgart (IAG).
