Keywords: cranked arrow wing, rolling moment, vortex interaction, SST

Low speed wind tunnel tests were made for cranked arrow wings with different wing planforms to understand vortex interaction behaviors between the inboard and outboard vortices. The following three parameters are focused: outboard wing sweepback angles, inboard wing sweepback angles and inboard/outboard wing kink locations.
