Abstract
A two-spool bypass turbojet includes a low-pressure spool having a rear portion carrying a low-pressure turbine provided with a low-pressure rotor. The turbojet includes a support structure connected to a casing and to a rear bearing in which the rotor is mounted. The bearing can be situated in an enclosure including a liquid lubricant feed. The enclosure can be put to atmospheric pressure via an air feed pipe connected to the enclosure via a link. The turbojet further includes an electricity generator connected to the rear end of the low-pressure rotor that extends downstream from the link, which link is secured to the rotor and includes a device for guiding the liquid lubricant from the feed to the bearing.
