Description: This video footage shows the flutter behavior of the scale model in the low-speed low-turbulence wind tunnel (LLT) of Delft University of Technology during the test campaign from 8 to 10 July 2013. The video starts from a camera perspective from inside one of the flutter constraints that restrict the possible motion of the wing tips and then continues through different perspectives of the wing at the onset of flutter while varying some of the problem parameters (chordwise and spanwise attachment of the bridle lines and pretensioning). The video concludes with a fast-motion sequence showing the flutter behavior at enforced symmetric and asymmetric deformations of the wing.
