Kurzfassung
A multibody modelling in SIMPACK of an ultra high bypass ratio (UHBR) engine is presented in this article. In this context, a hybrid approach is used: all rotor components of the engine are created as finite element models in ANSYS Mechanical and are then transferred as model order reduced bodies into the multibody environment. It is thereby possible to account for flexibility and consequently for phenomena such as gyroscopic moments. Multibody simulations are conducted with the UHBR engine model attached to a flexible wing model. The angular momentum of the engine is varied in order to achieve a change of the gyroscopic moments and to assess their influence on the wing dynamics. In that regard, the results revealed a strong gyroscopic coupling between wing and UHBR engine. As a consequence, it can be stated that gyroscopics should not be neglected in the design process of an aircraft.
