Current Biology, 2003 The fluttering flight of butterflies is characteristic of these insects but belies the fact that most species are competent or strong fliers with several members carrying out spectacular migrations. However, new work by a team led by Angel Viloria based at the Natural History Museum in London, report in the Proceedings of the Royal Society published ...

Suppression of Bridge Flutter Using Suction Control
Advances in Civil Engineering, 2021 To verify the effectiveness of the suction-based method for improving flutter stability of long-span bridges, the forced vibration experiments for extracting the flutter derivatives of a section model with and without suction were performed, and the ...

The Effect of Laminated Layers on the Flutter Speed of Composite Wing
Journal of Engineering, 2023 The paper presents an investigation to the flutter speed of composite wing for different ply orientation. Structurally the composite wing was idealized as a composite beam load carrying structure. Theodorsen’s expression was used to get the 2- dimension
