    摘要: The present disclosure is directed to lubrication systems for gear systems of a gas turbine engine. In one embodiment, a lubrication system includes an auxiliary reservoir configured to store lubricant and a lubrication collection device. The auxiliary reservoir is contained within an annular structure of the gas turbine engine. The lubricant collection device can collect lubricant from a gear system of the gas turbine engine and direct collected lubricant to the auxiliary reservoir. The auxiliary reservoir is configured to receive collected lubricant by way of a channel within the annular structure. The lubrication system may compliment a main lubrication system, and in particular, when the main lubrication system is temporarily unable to supply lubricant to the gear system.

    摘要: Disclosed herein is a system includes a lubricated component and a lubricant pump that selectively provides lubricant to the lubricated component. The system also includes a lubricant source in lubricant providing communication with the lubricant pump. Additionally, the system includes a lubricant flow regulation device in lubricant receiving communication with the lubricated component and lubricant providing communication with the lubricant source. The lubricant flow regulation device is configured to drain lubricant from the lubricated component to the lubricant source based on when the lubricant pump provides lubricant to the lubricated component, and to prevent drainage of lubricant from the lubricated component to the lubricant source based on when the lubricant pump stops providing lubricant to the lubricated component.
