Abstract
A method for assembling a gas turbine engine includes coupling a low-pressure turbine to a core turbine engine, coupling a counter-rotating fan assembly including a forward fan assembly and an axially aft fan assembly to the low-pressure turbine such that the forward fan assembly rotates in a first direction and the aft fan assembly rotates in an opposite second direction, and coupling a booster compressor directly to the low-pressure turbine such that the booster compressor rotates in the first direction.

A method for assembling a gas turbine engine comprising:
- coupling a low-pressure turbine to a core turbine engine;
- coupling a counter-rotating fan assembly including a forward fan assembly and an axially aft fan assembly to the low-pressure turbine, using a single shaft, such that the forward fan assembly rotates in a first direction and the aft fan assembly rotates in an opposite second direction;
- and
- coupling a booster compressor directly to the low-pressure turbine downstream of said a counter-rotating fan assembly such that the booster compressor rotates solely in the first direction.
A gas turbine engine assembly, comprising:
- a core gas turbine engine;
- a low-pressure turbine coupled to said core turbine engine;
- a counter-rotating fan assembly comprising a forward fan assembly and an aft fan assembly, each fan assembly drivingly coupled to said low-pressure turbine using a single shaft;
- and
- a booster compressor, downstream of the counter-rotating fan assembly, coupled directly to said low-pressure turbine such that said booster compressor and said low-pressure turbine solely rotate in the same direction.
