These highly flexible dynamic systems can exhibit uncommon aeroelastic instabilities, which should be carefully investigated to ensure safe operation. The interaction between the propeller and the wing is of particular importance. It is known that whirl flutter is stabilized by wing motion and wing aerodynamics. This paper investigates the effect of a propeller onto wing flutter as a function of span position and mounting stiffness between the propeller and wing. The analysis of a comparison between a tractor and pusher configuration has shown that the coupled system is more stable than the standalone wing for propeller positions near the wing tip for both configurations. The wing fluttermechanism is mostly affected by the mass of the propeller and the resulting change in eigenfrequencies of the wing. For very weak mounting stiffnesses, whirl flutter occurs, which was shown to be stabilized compared to a standalone propeller due to wing motion. On the other hand, the pusher configuration is, as to be expected, the more critical configuration due to the attached mass behind the elastic axis.}, language = {de} } @article{GollandEngling2014, author = {Golland, Alexander and Engling, Christoph}, title = {a-i3/BSI Symposium 2014: Sicherheit von Daten und Identit{\"a}ten angesichts NSA und Big Data}, series = {DSB Datenschutz-Berater}, volume = {38}, journal = {DSB Datenschutz-Berater}, number = {7-8}, publisher = {dfv Mediengruppe}, address = {Frankfurt a.M.}, isbn = {0170-7256}, pages = {165 -- 166}, year = {2014}, language = {de} } @book{Eckey2008, author = {Eckey, Ulrich}, title = {Aachen, K{\o}benhavn, 2008 / Damm, Patricia ; [Hrsg: Eckey, Ulrich]}, publisher = {FH Aachen}, address = {Aachen}, pages = {129 S. zahlr.
