A mid-fidelity aerodynamic solver based on the vortex particle method for wake modeling, DUST, is coupled through partitioned multi-physics coupling library preCICE to a multibody dynamics code, MBDyn, improve accuracy of aeroelastic numerical analysis performed rotary-wing vehicles. In this paper, tool firstly validated by solving simple fixed-wing and problems from open literature. The transi...

Abstract The aeroelastic loads and design processes at the German Aerospace Center, Institute of Aeroelasticity in framework multi-disciplinary optimization are constantly evolving. New developments have been made in-house model generation tool ModGen, which allow us to create detailed fuselage models for preliminary design. As a part subsequent integrate structure our process, new optimizing h...

There are a number of existing methods to transfer information among various disciplines. For a multidisciplinary application with n disciplines, the traditional methods may be required to model ) ( 2 n n − interactions. This paper presents a unified three-dimensional approach that reduces the number of interactions from ) ( 2 n n − to n 2 by using a computer-aided design model. The proposed mo...

In this work, the enhanced correction factor technique (ECFT) is modified for a subsonic wing–body interference model, which can consider forces on both lifting boxes and body elements of an idealized airplane, termed advanced ECFT method. A passenger aircraft model chosen as simulation longitudinal static aeroelasticity at transonic situation two-degree freedom, including α (angle attack) degr...
