Coupling of MBS and CFD: an oscillating aeroelastic wing model

Abstract

Multi-body simulation has been shown to be a valuable software tool for virtual aircraft design. It is a standard approach for the analysis of landing gears, of aircraft on the ground, and for the design of high-lift systems. The medium level of complexity of typical multi-body models also makes it a suitable tool for the application of flight mechanics in combination with elastic deformations. The development of reliable aerodynamic models, in addition to the existing interface for complex elastic structures, has been a major activity in the DLR Institute of Aeroelasticity during the past several years. The coupling procedure of SIMPACK to CFD is shown in this article for the application of the Aeroelastic Model Programme (AMP) wind tunnel wing simulated with SIMPACK and the DLR TAU code.
