The object of this study is a system consisting of a rigid thin-walled cylinder of finite span, mounted on an elastic cantilever beam transversely to the direction of the subsonic air flow in a wind tunnel. The purpose is to identify and analyze the mechanisms of various types of aero-elastic resonant excitation of the system for the use in energy harvesting designs based on vortex-induced vibrations. The results of an experimental study are presented. In contrast to similar works with a similar configuration of the model that performs transverse translational oscillations, we discovered previously unexplored VIVs type in which the cylinder rotates around the cantilever support.
