Abstract

A method for manufacturing a leading edge (11) profile section (30) of an aircraft lifting surface is provided. The method comprises the following steps: a) providing a set of laminated preforms (31,33) of a composite material configured with a suitable shape for constituting the leading edge profile section; b) arranging said laminated preforms in a curing tooling and subjecting the assembly to an autoclave cycle to co-cure said laminated preforms; c) demoulding the curing tooling in a spanwise direction towards the aircraft symmetry plane. The invention also comprises a leading edge profile section (30) manufactured by said method comprising in addition to the skin of the leading edge profile section, one or more of the following structural elements: an auxiliary spar (33), a longitudinal stiffener (35) reinforcing an auxiliary spar, a longitudinal stringer (37,37') reinforcing the skin of the leading edge profile.
