METHOD OF OPERATING A LUBRICATION SYSTEM FOR A TURBINE ENGINE
20250035013 · 2025-01-30 ·

A method of operating a lubrication system for a turbine engine having a fan and one or more rotating components. The lubrication system includes a primary lubrication system and an auxiliary lubrication system. The method includes supplying lubricant to the one or more rotating components from the primary lubrication system during a normal operation of the turbine engine, determining whether at least one of a fuel pressure is less than a fuel pressure threshold or a hydraulic pressure is less than a hydraulic pressure threshold, and activating the auxiliary lubrication system to supply the lubricant to the one or more rotating components from the auxiliary lubrication system when the fuel pressure is less than the fuel pressure threshold or the hydraulic pressure is less than the hydraulic pressure threshold.
