Claim Text:
1. A method of bonding a metal fairing for protecting a leading edge of an aircraft airfoil, an adhesive being disposed between the metal fairing and the airfoil, a bonding device being arranged around an outside face of the metal fairing, the bonding device comprising a rigid yoke in which induction heater means are inserted for heating the metal fairing, and wherein the induction heater means are arranged between first and second primary layers of a thermo-expandable material, the second primary layer matching a shape of the metal fairing while the device is in use, said method comprising the following steps performed in succession: a) induction heating the metal fairing with the help of the bonding device to reach a first temperature at which the adhesive is liquefied so as to wet the airfoil and the metal fairing; b) at the end of a first duration, heating the fairing to reach a second temperature enabling the adhesive to polymerize; c) at the end of a second duration, heating the metal fairing to reach a third temperature in order to enable polymerization to be complete and uniform; and d) at the end of a third duration, cooling the metal fairing.
