A turbomachine includes a low-pressure shaft having an internal passage for a first air stream and a first segment. A second segment includes a first frustoconical portion, and an intermediate lubrication chamber wherein at least one bearing is arranged. The intermediate lubrication chamber is arranged in an intermediate casing. An annular air chamber is configured to be supplied with air from a low-pressure compressor and is at least partly axially delimited by the first frustoconical portion. A radial separating wall is mounted around the first segment, and the first frustoconical portion further includes an opening to enable the first air stream to pass from the air chamber to the internal passage.

Turbomachine for an aircraft

A scoop for an aircraft turbine engine, this scoop including a body which is movable between at least two positions, including a first position in which it is configured to capture part of a first air stream flowing in a first direction, wherein the body is movable into a second position in which it is configured to capture part of a second air stream flowing in a second direction which is opposite to the first direction, and wherein the body is mounted to move freely between the at least two positions so as to automatically adopt the first position when the first air stream flows, and to automatically adopt the second position when the second air stream flows.

Scoop for an aircraft turbine engine

Auxiliary lead-through device for a turbomachine, including two coaxial annular shell rings, respectively an inner and an outer one, between which there extend radial arms, through at least one of which auxiliaries () are led through. An auxiliary retention unit is housed inside the arm, on one wall, the arm includes an aperture that can be closed off by a cover that is attached and fixed to the arm. The retention unit includes at least one first member fixed to the internal surface of the arm and at least one second member fixed to the internal surface of the cover. The fixing of the cover to the arm causes the auxiliaries to be clamped and retained between the first and second members.
