Vortex Breakdown over Unsteady Delta Wings and Its Control

H. Yang, Ismet Gursul

Abstract

One objective of this work is to provide information about the variation of swirl angle. The second objective is the control of leading-edge vortices. For this purpose, leading-edge vortices and vortex breakdown over a delta wing with variable sweep was investigated by flow vizualisation and laser Doppler velocimetry (LDV) measurements. Periodic variations of the sweep angle are used to control breakdown location for a pitching delta wing.
