    摘要: The invention relates to the field of rotary blades and more particularly to a method of manufacturing a leading edge shield intended to protect such a blade. This method involves at least the steps of initial plastic deformation of at least one sheet out of a pressure-face sheet (17) and a suction-face sheet (18), using additive manufacturing to add a reinforcer (15, 16) with fibrous insert (14) to at least one of said pressure-face and suction-face sheets (17, 18), closing said pressure face and suction-face sheets (17, 18) around a core (20), after said initial plastic deformation and the addition of each reinforcer (15, 16), subsequent plastic deformation, by compression against an external surface of the core (20) of said pressure-face and suction-face sheets (17, 18) after they have been closed around the core (20), and extracting the core (20).
