Abstract

A lubrication system for a turbine engine. The turbine engine includes a propulsor and one or more rotating components. The lubrication system includes a sump, a primary lubrication system, an auxiliary lubrication system, and a fuel system. The sump stores lubricant therein. The primary lubrication system supplies the lubricant from the sump to the one or more rotating components during normal operation of the turbine engine. The auxiliary lubrication system includes an auxiliary pump. The fuel system stores hydrogen fuel. The fuel system includes a fuel cell controller that generates electricity from the hydrogen fuel. The electricity powers the auxiliary pump when the propulsor is windmilling such that the auxiliary pump pumps the lubricant from the sump to the one or more rotating components.
