Abstract
A Lubrication system for an engine component of a gas turbine engine, such as a planetary gearbox. The system comprises a main lubrication system comprising a main tank configured to supply lubricant to the engine component, and a main reservoir configured to collect lubricant scavenged from the engine component after lubrication; and an auxiliary lubrication system comprising an auxiliary reservoir configured to collect lubricant scavenged from the engine component after lubrication and to supply scavenged lubricant to the engine component. Main reservoir comprises an interior and the auxiliary reservoir is located within the interior of the main reservoir. The auxiliary reservoir comprises an upper portion, a lower portion and a lubricant pickup region, the upper portion comprising an opening arranged to permit lubricant to overflow into the main reservoir, and the lower portion of the auxiliary reservoir being shaped to cause lubricant to drain towards the lubricant pickup region.
