Abstract
Leading edge of supporting surfaces of aircraft. A primary structure (EP) made without ribs is assembled with a specific frontal area (ZF) against impacts. The primary structure comprises two upper and lower covering panels (1, 2) and two diagonal and frontal spars (3, 4), which constitute the strong and rigid structural assembly of the leading edge (BA). The frontal area (ZF) is made up of one or two elemental parts which determine a kind of roof tile which closes the outer aerodynamic contour of the profile of the leading edge (BA) and provides a good behaviour against erosion, operational impacts on the ground and the impact of birds in flight. The invention is applicable to wings, stabilizers and control surfaces of aeroplanes.
