Abstract:
1. Method of manufacture of one or more pairs of aerofoil components for use in an aircraft having an axis of symmetry said components being made of a composite material designed to form part of two aerofiols to be located on each side of the axis of symmetry of a specified aircraft model and whose shape has a decreasing cross section in the longitudinal direction, the angle between the longitudinal edges of said components, in a planar projection, being less than 10°, which method comprises the following stages: a) Lay-up of layers of composite material arranged with different orientations of their reinforcing fibres on a flat tape lay-up table forming a laminate lay-out comprising all of the components of said pairs, the components of each pair being arranged adjacently so as to minimize the amount of material between adjacent pairs and the first components corresponding to one of said aerofoils and the second components corresponding to the other aerofoil being arranged alternately, and the whole being arranged symmetrically relative to a horizontal axis of the tape lay-up jig; b) Cutting of the flat laminates corresponding to each of the components of said pairs; c) Forming and curing of the components of said pairs.
