Abstract

An oil supply system and a method for operating the same to provide oil to a gas turbine engine in a variety of harsh operating conditions is provided. The oil supply system includes a main oil tank and an auxiliary oil tank which share oil through a tank sharing valve that may be closed if a depressurization event occurs in the main oil tank. The oil supply system further includes an auxiliary supply conduit and an auxiliary oil pump for providing oil to the gas turbine engine in the event of main oil tank depressurization or in negative gravity conditions where the oil within the auxiliary oil tank rises to the top of the tank and uncovers the oil pump supply.

Description

[0001] Federal Research Statement [0002] This invention was made with Government support under Contract No. W58RGZ-16-C-0047 awarded by U.S. Army Contracting Command-Redstone. The government has certain rights in this invention. technical field [0003] This topic generally relates to engine lubrication systems. More specifically, the subject matter relates to oil supply systems for lubricating gas turbine engines under various operating conditions. Background technique [0004] A gas turbine engine typically includes a fan and a core arranged in flow communication with each other. Additionally, the core of a gas turbine engine typically includes a compressor section, a combustion section, a turbine section and an exhaust section in a serial flow order. In operation, air is supplied from a fan to the inlet of the compressor section where one or more axial compressors gradually compress the air until it reaches the combustion section. Fuel is mixed with compressed air a...
