an outer skin formed with an aerodynamic leading edge profile, and
an inner reinforcement arranged internally with respect to the outer skin along a span of the leading edge section,
wherein said inner reinforcement comprises a base with a C-shaped configuration joined to an outermost part of the outer skin, a web having a free end and an opposite end joined to the base, the web extended in a direction transverse to a direction of the span of the leading edge section, and at least one pair of secondary reinforcements integral with both ends of the base of the inner reinforcement,
wherein the secondary reinforcements are proximate to terminal edges of each of the ends of the base of the inner reinforcement,
wherein the inner reinforcement is fabricated as a single component, and
wherein the free end of the web extends beyond the base a distance at least twice as large as a radius of curvature of the base.
