Virtual design, i.e. the extensive computer-aided design and layout of a product, is one of the key technologies in the development of new transport aircraft. Multibody simulation has shown to be a valuable software tool for virtual design, especially in the area of ground manoeuvres (take-off, landing, taxiing, ground handling). Comprehensive simulation of the system allows to analyse and evaluate performance, structural loading and dynamic behaviour of the concept. It is becoming more and more important to perform these computations in complex, realistic scenarios. Accounting adequately for aerodynamic effects on the flexible aircraft structure is an essential factor for such interdisciplinary simulations. This research work presents an approach to analyse the dynamics of the free-flying, manoeuvring elastic aircraft with focus on the particular requirements of ground manoeuvres simulation. Special attention has been turned to questions of practical applicability, in particular efficient modelling in an interdisciplinary environment and fast computation of the job. The approach of aeroelastic preprocessing allows to execute the aerodynamic analyses and the fluid-structure coupling prior to the time integration of the multibody simulation. This ensures user-friendly modelling which can be widely automised, and supports low computation times for a complex multibody analysis of the aircraft.
