Counter-rotating fan assembly and gas turbine engine assembly including counter-rotating fan assembly

摘要

A method for assembling a gas turbine engine (10) includes coupling a low-pressure turbine (14) to a core turbine engine (12), coupling a gearbox (100) to the low-pressure turbine, coupling a first fan assembly (50) to the gearbox such that the first fan assembly rotates in a first direction (80), and coupling a mechanical fuse (200) between the first fan assembly and the low-pressure turbine such that the mechanical fuse fails at a predetermined moment load.
