摘要：
The invention relates to a method for creating an aerodynamic element, notably for an aircraft, comprising an external face and plurality of parallel ribs and/or grooves formed on the said external face, the method consisting in creating the said element and its ribs and/or grooves simultaneously by use of a mould (22), characterized in that the method comprises: - a step of supplying a film (28) made of a deformable material, which has ribs and/or grooves that complement the ribs and/or the grooves of the said element, - a step of positioning the film (28) on a wall (26) of the mould (22), - a step of moulding the element, - a step of separating the element from the mould (22), simultaneously with the said film (28), and - a step of separating the film (28) from the element. The invention also relates to a mould (22) for implementing the method.
