The multi-body simulation model was developed, which describes more adequate the free flying aerodynamic structures with large deformations compared to the CFD-FEM analysis. The chordwise lift distribution calculated by the inbuilt vortex-lattice method needed to be corrected. The parameter identification was based on a scale model and flight path measurements.
