Method for disconnecting, by induction, a magnetic mechanical part adhered to a mechanical part
View Patent ↗A method for disconnecting a first mechanical part from a second magnetic mechanical part, the first mechanical part being adhered to the second magnetic mechanical part by an adhesive film along a connecting area. In the method, a magnetic field is generated at least within the connecting area so as to generate, by induction, eddy currents in the second magnetic mechanical part, to soften the adhesive film and enable disconnection of the first and second mechanical parts.
1. A method for disconnecting a first mechanical part from a magnetic second mechanical part, the first mechanical part being adhered to the magnetic second mechanical part by an adhesive film along a connecting area, the method comprising:
generating a magnetic field, at least in the connecting area, so as to generate by induction eddy currents in the magnetic second mechanical part to soften the adhesive film and enable disconnecting of the first and second mechanical parts.
2. A method according to claim 1 , wherein the first mechanical part is a part made of composite material or is non-magnetic.
3. A method according to claim 1 , wherein the first mechanical part is a turboshaft engine blade.
4. A method according to claim 3 , wherein the turboshaft engine blade is made of a composite material having an organic matrix.
5. A method according to claim 3 , wherein the magnetic second mechanical part is a shield for a turboshaft engine blade.
6. A method according to claim 5 , wherein the shield is made of metal.
7. A method according to claim 3 , wherein, the turboshaft engine blade includes a leading edge, and the shield is arranged to be adhered to the leading edge of the blade.
8. A method according to claim 1 , wherein the first mechanical part is a turboshaft engine casing and the magnetic second mechanical part is a magnetic insert.
