FIELD: aircraft engineering.
SUBSTANCE: oil tank breathing line is provided with an extra heat exchanger with its outlet connected to a breather-separator inlet while the outlet of the latter is communicated with atmosphere. Note here that an air separator is fitted in the oil tank to make its air discharge line communicate with the oil tank free volume while the oil feed channel is communicated with the line of the rotor bearings oil chambers breathing line.
EFFECT: reduced oil consumption owing to oil vapour condensation in the breathing system and oil discharge system.
