Keywords: SST, Leading-edge separation vortex, Vortex interaction
Wind tunnel tests were performed to investigate the vortex behaviors over a cranked arrow wing configuration at high angles of attack. Vortical flows were surveyed by the stereoscopic PIV technique and static pressure measurements. Interactions of the inboard and the outboard leading-edge separation vortices were observed as the inboard and outboard leading-edge flap deflects.
