Abstract: A device for protecting an airfoil element made of a complex comprising a polymer film, a metal strip deposited on a part of the polymer film and an adhesive element to attach the polymer film on the airfoil element. The polymer film forms a protection against sand abrasion. The metal strip forms a protection against water abrasion of the airfoil element on which the complex is attached.

Abstract: A structure (10) for aircrafts, includes a part (20) including a metal leading edge (30), the leading edge (30) being covered by a coating (40) having a thickness which is less than or equal to ten micrometers and having a hardness higher than six hundred in the Vickers hardness test (HV). According to a mode of embodiment, the coating (40) is a multilayer stainless steel coating consisting of a superposition of layers with a low nitrogen gradient and layers with a high nitrogen gradient, the layers having a thickness essentially equal to a micrometer. An aircraft including such a structure is also described.

Abstract: The present invention relates to a method and to a device (1) for bonding a metal fairing (6) to protect a leading edge of an aircraft airfoil (7), said metal fairing (6) being designed to be bonded against said airfoil (7) with the help of an adhesive (9). The bonding device (1) is remarkable in that it includes a rigid yoke (2) having inserted therein induction heater means (30) for heating said metal fairing (6).
