초록

A pump system for lubricating a bearing in a gear system of a gas turbine engine includes a main pump, an auxiliary pump, an auxiliary reservoir, a sump, and a valve system. The main pump is fluidically connected to the bearing through a main supply passage. The auxiliary pump is fluidically connected to the bearing through an auxiliary supply passage. The valve system transfers lubricating liquid from the main pump to the bearing under a first set of engine operating conditions. The valve system transfers lubricating liquid from the auxiliary reservoir ...
