摘要： The invention relates to a turbojet engine oil tank (30). The tank (30) comprises a main chamber and an envelope (34) delimiting the main chamber, and a fixing portion (44) for example with fixing flanges (46) and a branch (48). The envelope (34) features in particular an envelope part (34) relative to which the fixing portion (44) projects. The envelope part (34) and the fixing portion (44) are produced by layered additive fabrication so as to be in one piece. The invention also relates to a method of fabricating an oil tank (30).

摘要： 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 (58) for each tank, whereof a first shell section (58) has a recess (60) and a second shell section (58) a boss (62); (b) production of the shell sections (58) by additive manufacturing in which the boss (62) on the second shell section is produced in the recess (60) in the first shell section; then (c) welding of the sections (60) one to the other.
