FIELD: aircraft industry, mechanical engineering and other spheres of application.
SUBSTANCE: invention relates to lubrication of rotor supports of gas-turbine engine, particularly, to methods of venting of rotor support oil spaces. According to proposed method including oil supply into oil space of rotor support and draw out of air-oil mixture into mixture into breather along venting main line, additional oil is delivered into oil space of rotor support and is directed to inlet of venting main line. Amount of additional oil is not less than 1% of amount of oil delivered into rotor support for lubrication and cooling of friction parts and units.
EFFECT: improved reliability of operation of gas-turbine engine by reducing formation of coke deposits in venting main line.
