LUBRICATION SYSTEM FOR GEARED GAS TURBINE ENGINE

摘要

An oil cooling system is provided. The system may comprise an oil inlet, a manifold (142) fluidly coupled to the oil inlet, and a support strut (126) comprising internal tubing (132) fluidly coupled to the manifold (142). A heat exchanger (128) may be fluidly coupled to the internal tubing (132) of the support strut (126). A nose cone (130) may be disposed forward of the heat exchanger (128) and configured to rotate about an axis (A-A'). The heat exchanger (128) may be radially inward from a portion of the nose cone (130). A gas turbine engine (20) is also provided. The gas turbine engine (20) may comprise an epicyclic gear system (100) and fan (42) mechanically coupled to the epicyclic gear system (100). The fan (42) may be configured to rotate about an axis (A-A'). A nose cone (130) may be coupled to the fan (42) and configured to rotate about the axis (A-A'). A heat exchanger (128) may be forward of the fan (42) and in fluid communication with the epicyclic gear system (100).
