Combined time-resolved PIV and structure deformation measurements for aero-elastic investigations

Abstract

The interaction of structural (elastic and inertial) as well as aerodynamic forces causes com-plex dynamic aeroelasticity problems. Part of this is the flutter phenomena which is potential-ly destructive and needs to be avoided in most cases. Great effort is made experimentally and numerically for the safety of light weight structures in aeronautics. But experimental in-vestigations of aeroelastic phenomena still represent great challenges
