Abstract
An oil system of a gas turbine engine, includes a first oil circuit and a second oil circuit. Via the oil circuits, oil is supplied to a hydraulic load of a transmission of the engine. Downstream of the load, in the region of a return of the transmission, oil is introduced into the oil circuits from the transmission. Upstream of the load, in the region of inlets, oil can be introduced into the transmission from the oil circuits. The second oil circuit includes an oil accumulator between the return and the inlet of the second oil circuit. The oil accumulator is configured such that, according to a feed pressure of the oil upstream of the inlet, oil is stored in the oil accumulator or oil stored in the oil accumulator is fed toward the inlet.
