FIELD: mechanical engineering; gas-turbine engines.
SUBSTANCE: invention relates to lubrication systems of mechanical devices for instance, engines, and to devices indicating presence of metal particles in lubrication system which makes it possible to diagnose beginning of destruction of engine if chips appear in oil. Lubrication system of gas-turbine engine includes engine oil sump, oil feed and scavenge main lines and oil spaces breathing lines, oil tank, oil feed and scavenge pumps, oil temperature electric transmitter and metal particles electric detector installed on oil scavenge main line. Oil temperature transmitter is installed on oil scavenge main line in one housing with oil metal particles detector in oil, and wires to transmit signal are connected to common connector coupled with engine electric wire bundle.
EFFECT: improved reliability of chips detection and reliability of operation of lubrication system and engine as a whole.
