An aircraft with a wing-hung layout has a nose cone structure for a pylon. A front nose cone is located in front of a wing leading edge, and a rear nose cone is located behind the wing leading edge. At least a part of the rear nose cone is modeled and shaped by cross section control lines and has at least one group of horizontal position control lines and at least one group of longitudinal position control lines. The rear nose cone of the pylon is shaped by horizontal position control lines. By controlling the rear nose cone curvature of the pylon the passageway area of the space between the pylon/wing/engine nacelle is optimized without deflection of the rear portion of the pylon.
