Abstract: The invention relates to a method for manufacturing a cellular structure comprising the following steps: a) providing a plurality of metal sheets (126) each having, in a first direction, undulations formed by a succession of vertex areas (28) alternately arranged with junction areas (30); b) juxtaposing the sheets (126) so as to form cells; c) placing a first (26a) end of each sheet (126) in contact with a support plate; d) arranging a soldering element between the support plate (34) and the first ends (26a) of the sheets (126) and heating the assembly in a furnace. According to the invention, the method consists, prior to step d), in adding a means for blocking the diffusion of solder from said first ends (26a) of the sheets (126) to the second free ends (26b) of the sheets (126).

Abstract: A distributor of a turbomachine configured to be mounted in a housing, including: a plurality of segments; a plurality of anti-rotation pins, mounted both on a segment of the distributor and on the housing; and a thermal protection sheet, including at least one axial tab configured to radially abut against an inner face of a first anti-rotation pin, and at least one radial tab configured to axially abut against an upstream face of a second anti-rotation pin.

Abstract: An electrical discharge machining tool of a ring sector for an aircraft turbomachine is provided. The ring sector includes an abradable member and a support element to which the abradable member is fixed; and one or more gripping holes opening on a radially outer surface of a central body of the support element. The machining tool includes at least two machining sets chosen from groove, notch, opening, length-cutting, or abradable element electro-machining sets. The machining tool also has a gripping device for the ring sector by the gripping holes. The gripping device is configured to move the ring sector from one of the electro-machining sets to another of the electro-machining sets.
