Kurzfassung
This report presents comprehensive flutter calculations of the DLR-D150-VAMP configuration with respect to the influence of structural changes on flutter behaviour. The main focus thereby was on the influence of modifications concerning the position of the engines/nacelles. Furthermore the influence of gyroscopic and thrust vector effects as well as the influence of pylon stiffness regarding the flutter behaviour has been investigated. Finally, the influence of an integrated ultra high bypass ratio engine/nacelle (UHBR) instead of a classical standard CFM56 engine on the flutter stability has been investigated. The results are shown in comparison to the aeroelastic flight envelope for this assessed configuration, which is similar to an A320 aircraft.
