SHIP MAIN GAS-TURBINE UNIT WITH REVERSIBLE ENGINE Russian patent published in 2019 - IPC B63H21/16 

FIELD: shipbuilding.

SUBSTANCE: invention relates to the field of main ship power plants, in particular, to main marine gas turbine units with reversible engine and gear reducer with gear pumps on its housing, driven from one of reduction gear shafts. Main ship gas turbine unit with reversible engine comprises reversible gas turbine engine, gear reducer, connecting couplings, pump for control of friction coupling with hydraulic control with first and second flanges on its housing with drive of both pumps from intermediate shaft of reduction gear, reserve electrically driven pump, pressure sensor, filter and oil cooler, shutoff, reduction and check valves and oil lines. First flange of the lubrication pump is connected by an oil pipeline with the first check valve placed in it in series with possibility of its opening to the side opposite to the lubrication pump. Second flange of the lubrication pump is connected by a suction oil pipeline with the third check valve with an oil casing of the reducer installed in it with the possibility of opening to the side of this pump. Second flange of control pump is connected by oil line with arranged therein in series seventh check valve with possibility of its opening in opposite direction from pump control side and with shutoff valve with control cavity of friction coupling with hydraulic control in gear wheel on intermediate shaft of reduction gear.

EFFECT: enabling increase in the main ship gas turbine unit operation reliability and efficiency with the reversible engine.
