Oil system of a gas turbine engine with a first oil circuit and with at least one second oil circuit and a gas turbine engine

摘要

An oil system (42) of a gas turbine engine (10) with a first oil circuit (43) and with at least one second oil circuit (45) is described. At least one hydraulic consumer (62) of a transmission (30) of the gas turbine engine (10) can be charged with oil via the oil circuits (43, 45). Downstream of the hydraulic consumer (62), oil can be introduced in the area of a return (50) of the transmission (30) from the transmission (30) into the oil circuits (43, 45) and in each case upstream of the consumer (62) from the oil circuits (43, 43). 45) can be introduced into the transmission (30) in the area of inlets (48, 49). At least the second oil circuit (45) is designed with an oil reservoir (70) between the return (50) of the transmission (30) and the inlet (49) of the second oil circuit (45). The oil reservoir (70) is designed in such a way that oil can be stored in the oil reservoir (70) or oil stored in the oil reservoir (70) in the direction of the upstream of the inlet (49) of the second oil circuit (45) depending on a supply pressure (p45) of the oil The inlet (49) of the second oil circuit (45) can be guided.
