Aeroelastic Computation Using the AMANDA Simulation Environment

Abstract

Within the DLR/HGF research project AMANDA a multidisciplinary simulation environment has been developed. The well established monodisciplinary DLR code FLOWer (Computational Fluid Dynamics, CFD), TAU (CFD) and SIMPACK (Multi Body Simulation, MBS) as well as commercial codes like NASTRAN (Computational Structure Mechanics, CSM) are integrated into the environment. The data exchange needed between the monodisciplinary codes is realized by the MpCCI communication library developed by GMD. The AMANDA environment now enables aerothermal and aeroelastic applications. The paper will concentrated on the latter one. The components developed by DLR and the MpCCI library will be described with emphasis on the CFD-codes and their adaptions needed for aeroelastic applications. First steady and unsteady aeroelastic applications for the airbus like AMP wing as well as for an A340 like aircraft under cruise conditions will be presented, to demonstrate the feasibility of the AMANDA simulation environment.
