The invention relates to a method of manufacturing at least one tank with a shell, in particular a turbojet engine oil tank. The method comprises the following stages: (a) definition of different shell sections () for each tank, whereof a first shell section () has a recess () and a second shell section () a boss (); (b) production of the shell sections () by additive manufacturing in which the boss () on the second shell section is produced in the recess () in the first shell section; then (c) welding of the sections () one to the other.

Additive manufacturing method for a turbofan engine oil tank

A strainer for filtration in an oil circuit of a turbine engine, in particular a multi-flow turbojet engine, is housed in a bore of a lubrication assembly. The oil serves to lubricate and cool mechanisms of the turbine engine. The strainer includes a filtering portion as an angular tube portion and a holding structure for the filtering portion. The structure forms a thickening and exhibits rings and structural posts. A magnet is added in a socket formed by the structure. The structure and the filtering portion are integral and are produced by additive manufacturing, which simplifies production. The application likewise relates to a method of producing the strainer.
