LUBRICANT CIRCULATION SYSTEM AND METHOD OF CIRCULATING LUBRICANT IN A GAS TURBINE ENGINE

摘要

A lubricant circulation system and method of circulating lubricant in a gas turbine engine (20) are disclosed. The lubricant circulation system includes a nose cone (66) having an aperture (74) communicating air to an interior space (72) of the nose cone, a heat exchanger (100) disposed in the interior space, and a lubricant circulation pathway (210) contained within a forward portion (212) of the gas turbine engine and configured to circulate lubricant through the heat exchanger.
