Aeroelastic modeling of macrobody aircraft for real-time-flight simulation

The trend to larger transport aircraft leads to new problems, which require an integrated point of view already in the pre-development phase. Due to the close coupling of flight mechanical and structural modes a quasi-stationary model is no longer adequate to describe the aircraft behavior for flightmechanical investigations on flying qualities. For some of those investigations pilot-in-the-loop analysis of flight dynamics are necessary, which have to be carried out using a flight simulator. This paper presents the development of a real-time capable model for a very large, flexible transport aircraft.
