FIELD: aircraft engineering; aircraft engines.
SUBSTANCE: invention relates to breathing system devices of aircraft gas-turbine engine with oil space differing in pressure levels. In proposed centrifugal breather containing housing with air-oil mixture feed channels, cleaned air and entrapped oil removal channels, and rotor on which bladed wheel with ports for air-oil mixture supply and cleaned air removal is secured, said bladed wheel is made in form of two separate impellers turned by inputs to different sides opposite to separate air oil mixture feed channels of housing. Ports to remove cleaned air in impellers communicate through mixing chamber in housing with channel to remove cleaned air from housing, and channels to remove entrapped oil are made separated in housing.
EFFECT: reduced flow rate of oil through breathing system of engine.
