The turbulent flowfield above the wing of a delta-canard-configuration at moderate (a = 15) and high (a = 24) angle of attack was measured at a Re-number of 0.97.106 in a wind tunnel by hotwire anemometry. Leading edge flap settings of el.e. = 0 and el.e. = -20 were used. At moderate angle of attack and deflected leading edge flap a strong vortex originates from the side edge of the non-deflected inboard wing leading edge part. This inboard wing vortex is located close to the fuselage. It is a dominant flow feature and forms the center of the vortical flow separating from the wing surface. The separation line is clearly different from the leading edge flap hinge line. At high angle of attack the flow separates at the leading edge for both the non-deflected and deflected leading edge ease. The resulting leading edge vortex is subject to breakdown dose to the apex. In case of the deflected leading edge, the interaction of inboard wing vortex and leading edge vortex remits in decreased downstream expansion of the burst vortex, also reducing turbulence intensity levels.
