Vortex Behaviors of Rolled Supersonic Transport Configuration with Leading-Edge Flaps

: Wind tunnel tests were conducted to investigate static roll characteristics of three cranked arrow wings that have different outboard wing sweepback angles to investigate the effect of inboard and outboard vortices upon the wing roll characteristics. Results indicated that breakdown position of leading-edge separation vortex formed on the inboard wing moves upstream as the outboard wing sweepback angle is decreased. A large scale rolling moment hysteresis was observed for the wings with smaller outboard wing sweepback angle, whereas only a small scale hysteresis was observed for higher outboard wing sweepback angle. It was shown that these differences are caused by the different behaviors of inboard vortex breakdown.
