Aerodynamic Interference Caused by the Inboard Leading-Edge Flap on the Outboard Area of the Cranked Arrow Wing
Wind tunnel tests were conducted on a cranked arrow wing model to reveal the relationship between the inboard leading edge flaps and vortex behavior formed on the outboard wing area.Aerodynamic force measurements and flow visualizations on the upper surface of the wing were made.The pitching moment characteristics indicate that there are two non-linear changes and the flow patterns which caused those changes are observed.The flow patterns indicate that the non-linear changes are caused both by the flow separation on the outside of the inboard vortex and by the one on the outside of the merging position of the inboard and outboard vortices.It was found that the inboard leading edge flap decreases the angle of attack when recovery from the first change occurs.The inboard leading edge flap also causes an increase in the magnitude of the second change.
