    摘要: A leading edge structure is described for wing structures and empennage, comprising an outer shell suitable to define a front portion of a airfoil. The outer shell is formed by a bent plate of fiber-reinforced thermoplastic resin composite material. The structure further comprisesan inner shell having a convex profile that is oriented in the same direction as the profile of outer shell, which is formed by a bent plate of fiber-reinforced thermoplastic resin composite material and is bonded to the outer shell at the longitudinal edges thereof, andat least one reinforcing element, transversally extending such as to connect the outer shell and inner shell to each other , which is formed by at least one piece of fiber-reinforced resin composite material and is fixed at opposite ends to the outer shell and inner shell, respectively.
