Separation Control on a Cantilever Wing with a Self-Excited Vibrating Rod

The surface-How characteristics and aerodynamic performance of a cantilever wing model subjected to the influence of a leading-edge control rod are studied in a wind tunnel. Circular rods of various materials and diameters installed at various distances from the leading edge of the wing are tested at low chord Reynolds numbers. Some selected small-diameter rods present a self-excited transverse vibration when they are placed very close to the leading edge.
