Abstract
A lubrication system includes a control subsystem operable to selectively communicate lubricant from a reserve lubrication subsystem under a pressure to supplement lubricant from a main lubrication subsystem in response to identification of a prolonged reduced-G condition. A gas turbine engine includes a main lubrication subsystem in communication with a geared architecture; a reserve lubrication subsystem in communication with the geared architecture; and a control subsystem operable to selectively communicate lubricant from the reserve lubrication subsystem under a pressure in response to identification of a prolonged reduced-G condition. A method of reducing lubrication starvation from a lubrication system with a main lubrication subsystem and a reserve lubrication subsystem, the main lubrication system in communication with a geared architecture of a gas turbine engine, includes communicating lubricant under a pressure to the geared architecture in response to identifying of a prolonged reduced-G condition.
