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 ( ) and two diagonal and frontal spars ( ), 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.

A process for making a dismountable and/or fixed traction-compression coupling to be applied to composite materials, in which a basic laminate ( ) of composite material is folded at least once to obtain at least one skirt ( ) forming an angle close to 90&deg; with the rest of the laminate; by using a transition radius between the skirt and the rest of the laminate, a set of distribution plates ( ) is applied over the basic laminate to stabilize the skirt and produce a uniform load distribution, making holes in each set of distribution skirt-plates and introducing traction bolts ( ) with an initial pretension in said holes, hence obtaining the connection between the components to be joined. The invention is applicable to the aerodynamic structures of aircraft.
