Patent

CA 2524141

A method for assembling a gas turbine engine (10) that includes providing a first fan assembly (12) configured to rotate in a first rotational direction, rotatably coupling a second fan assembly (14) to the first fan assembly, wherein the second fan assembly is configured to rotate in a second rotational direction that is opposite the first rotational direction, coupling a first shaft (20) to the first fan assembly and to a first turbine rotor (38) that is configured to rotate in a first rotational direction, coupling a second shaft (22) coupled to the second fan assembly and to a second turbine rotor (42) that is configured to rotate in a second rotational direction that is opposite the first rotational direction, and coupling a lubrication system (200) to the gas turbine engine such that a lubrication fluid is channeled through the first shaft to lubricate at least one of the first and second fan assemblies.
