OIL SYSTEM OF A GAS TURBINE ENGINE, COMPRISING A FIRST OIL CIRCUIT AND AT LEAST ONE SECOND OIL CIRCUIT, AND GAS TURBINE ENGINE

摘要

The invention relates to an oil system (42) of a gas turbine engine (10), comprising a first oil circuit (43) and at least one second oil circuit (45). By means of the oil circuits (43, 45), oil can be supplied to at least one hydraulic load (62) of a transmission (30) of the gas turbine engine (10). Downstream of the hydraulic load (62), in the region of a return (50) of the transmission (30), oil can be introduced into the oil circuits (43, 45) from the transmission (30). Upstream of the load (62), in the region of inlets (48, 49), oil can be introduced into the transmission (30) from the oil circuits (43, 45). At least the second oil circuit (45) is provided with an oil accumulator (70) between the return (50) of the transmission (30) and the inlet (49) of the second oil circuit (45). The oil accumulator (70) is designed such that, according to a feed pressure (p45) of the oil upstream of the inlet (49) of the second oil circuit (45), oil can be stored in the oil accumulator (70) or oil stored in the oil accumulator (70) can be fed toward the inlet (49) of the second oil circuit (45).
