Aircraft wing structure profiled suspension pylon

The present invention relates to an aircraft wing structure profiled suspension pylon. According to the invention, the suspension pylon () comprises a fairing for reducing the local loss in lift and its maximum-width section () is located at the front of the concave and set-back rear part (R) of the pressure face () of the wing structure (). The fairing for reducing the local loss in lift ():is housed, at least over most of its height, in the concavity of said rear part (R) of the pressure face () of the wing structure (), andcomprises an underside () which comes close to its upper surface () as an aerodynamic continuation of the suction face () of the wing structure () so as to give the protruding rear part () of said fairing () the shape of a blade which tapers toward the rear and ends in an aerodynamic trailing edge ().
