UNSTEADY BEHAVIOR OF LEADING-EDGE VORTEX AT STATIC AND DYNAMIC MODEL CONDITIONS

X. Z. Huang
Institute for Aerospace Research/ NRC, Canada

Keywords: unsteady aerodynamics, leading-edge vortex, high angle of attack

Studies on the unsteady behavior of the leading-edge vortex, especially its breakdown, over delta wings at static and dynamic model conditions were conducted at free stream velocity up to M=0.3 and Re(mac) up to 2.4 million. Unsteady surface pressures wer measured at static and dynamic model conditions and flow visualization conducted.
