Interaction of Vortex Breakdown with a Flexible Fin and its Control
Abstract
This report results from a contract tasking University of Bath as follows: The contractor will investigate the fin buffeting caused by vortex breakdown and its control. In this phase, a flexible fin will be designed and fabricated. It consists of a thin brass spar surrounded by several balsa wood segments to provide aerodynamic shaping. Fin vibration levels will be sensed by root strain gages and tip accelerometers. Unsteady surface pressure measurements on the delta wing and underneath the vortex will be carried out in order to detect and quantify the oscillations of vortex breakdown location due to fin vibrations. Also, flow velocity measurements and visualization experiments will be carried out in U. of Bath water tunnel.
