Patent number: 10654225Abstract: A method of fabricating a blade. The blade comprises subassemblies made of thermoplastic composite materials, each subassembly comprising an internal arrangement and at least one external arrangement, each internal arrangement comprising a stack of intermediate layers comprising reinforcing fibers impregnated with a semicrystalline thermoplastic matrix, each external arrangement comprising at least one surface layer comprising reinforcing fibers impregnated with an alloy of a semicrystalline thermoplastic polymer and of an amorphous thermoplastic polymer. An assembly film comprising an amorphous thermoplastic material and a ferromagnetic member is interposed between two surface layers of two distinct subassemblies that are to be assembled together by a method of local heating by induction.Type: GrantFiled: May 24, 2017Date of Patent: May 19, 2020Assignee: AIRBUS HELICOPTERSInventor: Patrick Boschet

Patent number: 9981739Abstract: 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.Type: GrantFiled: March 13, 2014Date of Patent: May 29, 2018Assignees: AIRBUS GROUP SAS, EUROCOPTERInventors: Benjamin Luiset, Thomas Navarre, Patrick Boschet, Alain Billard

Patent number: 6578265Abstract: In order to remove a plate made from a material that can be heated by electromagnetic induction and retained on a supporting member by a heat-fusible adhesive, an inductor is displaced facing at least one strip of the plate in order to heat the strip by induction and heat the adhesive by conduction until the adhesive softens, and a tearing tool is driven so as to tear out the heated strip by hot-peeling. The inductor and the tearing tool are displaced jointly relative to the plate and the supporting member by means of a mobile frame, which is displaced on a stationary frame on which the supporting member and the plate are fixed.Type: GrantFiled: September 9, 2002Date of Patent: June 17, 2003Assignee: EurocopterInventors: Patrick Boschet, Daniel Brunner, André Amari
