1. A lubrication system for a turbine engine, the turbine engine including a propulsor and one or more rotating components, the lubrication system comprising:
a sump that stores lubricant therein;
a primary lubrication system supplying the lubricant from the sump to the one or more rotating components during normal operation of the turbine engine;
an auxiliary lubrication system comprising an auxiliary pump; and
a kinetic energy storage system comprising a rotating lubricant accumulator, wherein the auxiliary pump pumps the lubricant from the sump to the rotating lubricant accumulator to at least partially fill the rotating lubricant accumulator with the lubricant during the normal operation of the turbine engine to store kinetic energy, and the rotating lubricant accumulator releases the kinetic energy when the propulsor is windmilling to supply the lubricant from the rotating lubricant accumulator to the one or more rotating components.
