The present invention provides a nose cone structure for a pylon (20) of an aircraft with a wing-mounted layout. The nose cone comprises a front nose cone (21) located in front of a wing leading edge (31) and a rear nose cone (22) located behind the wing leading edge (31). The nose cone is characterized in that at least a part of the rear nose cone (22) is modeled and shaped by cross section control segments and comprises at least one group of latitudinal position control segments (P01, P02, P03, P04) and at least a group of longitudinal position control segments (S01, S02, S03, S04, S05). The rear nose cone of the pylon is shaped by latitudinal position control segments. The pylon design of the present application optimizes the passageway area of the space between the pylon/wing/engine nacelle by controlling the rear nose cone curvature of the pylon without deflection of the rear portion of the pylon.
