Abstract

The central challenge is to simulate the time-accurate aeroelastic coupling of the flexible aircraft body with a non-linear aerodynamic solver for specific flight manoeuvres which are introduced by rigid body motions of large amplitude. The approach described in this work is one of two investigated variants in the DLR project SikMa and is characterized by the use of a multibody system (MBS) to account for the elastic structure as well as the flight mechanics and its loose coupling to the computational fluid dynamics (CFD) software. The exchanged data is interpolated with a general mesh coupling tool and transferred through an internet socket allowing a distributed computational environment. The presented applications are coupled simulations for the wind tunnel setup of an elastic delta wing in both guided and free-to-roll manoeuvres.
