LUBRICATION SYSTEM FOR A TURBINE ENGINE

摘要

A lubrication system for a gas turbine engine includes a tank, a circulation pump, and a heat exchanger. The circulation pump generates a flow of lubricant from the tank to, e.g., a power gear box of the gas turbine engine and the heat exchanger removes an amount of heat from such flow of lubricant provided to the power gear box. The lubrication system also includes one or more valves in the flow of lubricant for controlling a flowrate and/or temperature of the lubricant provided to, e.g., the power gear box to increase an efficiency and/or durability of the power gear box.

1. A lubrication system for a gas turbine engine comprising:
a tank configured to store a volume of lubricant; a circulation pump for generating a flow of lubricant from the tank to a component of the gas turbine engine; a valve in fluid communication with the flow of lubricant generated by the circulation pump and defining a flow inlet and a flow outlet, the valve also defining a variable throughput between the flow inlet and the flow outlet for controlling a flowrate of lubricant to the component of the gas turbine engine; and a heat exchanger positioned in thermal communication with the flow of lubricant generated by the circulation pump at a location downstream of the valve for controlling a temperature of the lubricant prior to the lubricant reaching the component.
