Kurzfassung
Focus is the stability assessment of an aircraft equipped with the currently introduced high-efficiency engines of ultra high bypass ratio (UHBR) and to compare the critical flutter onset to the same aircraft using standard engines with a smaller fan diameter. The D150 configuration modelled in-house by DLR was chosen, since it is similar to the Airbus A320 in terms of size and dynamic behaviour. The setup of the aeroelastic model is shown and results from the flutter assessment clarify differences between the investigated standard and UHBR engine types with respect to the flutter onset. Here, the sensitivity study includes varying locations of the engine in front of the D150 wing and is based on unsteady aerodynamic forces from doublet lattice method (DLM). The aeroelastic models are analyzed with the commercial ZAERO aeroelastic software package.
