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

The invention relates to a turbojet engine oil tank (). The tank () comprises a main chamber and an envelope () delimiting the main chamber, and a fixing portion () for example with fixing flanges () and a branch (). The envelope () features in particular an envelope part () relative to which the fixing portion () projects. The envelope part () and the fixing portion () 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 ().

Turbomachine oil tank

An oil tank of a turbine engine, particularly of an aircraft turbojet includes an external wall forming a generally curved main cavity. This cavity includes an arched sensor for electrically measuring the oil level, for example in a capacitive manner. Said arched sensor matches the curvature of the main cavity in order to be integrated therein. Sensor supporting arms distributed along the curvature of the arched sensor and/or an arched sleeve with an arched cavity receive the arched sensor. A turbine engine is provided with an oil tank, as well as a method for mounting a sensor in an oil tank.

Oil level sensor tank for turbine engine

The present invention relates to a method for manufacturing a tank () comprising a main body () with several compartments (), a base () closing the lower part of the main body (), and a cover () closing the upper part of the main body (), said method comprising the following steps:
