歯車型差動速度二重反転式低圧タービン

Japanese Patent JP5844959

B2

A counter-rotatable low pressure turbine (26) includes counter-rotatable outer and inner drum rotors (68, 78). The outer drum rotor (68) is connected to a sole shaft for transmitting torque and power out of the low pressure turbine (26). Low pressure outer drum turbine blade rows (70) extend radially inwardly from an outer shell (66) of the outer drum rotor (68). Low pressure inner drum turbine blade rows (80) extend radially outwardly from the low pressure inner drum rotor (78). The outer drum turbine blade rows (70) are interdigitated with the inner drum turbine blade rows (80). The drum rotors (68, 78) are geared together through an epicyclic gearbox (56) for transmitting all the torque and power produced by the drum rotors (68, 78) to the shaft (74). The gearbox (56) may be located aft of the drum rotors (68, 78). A differential thrust bearing (112) is disposed between the drum rotors (68, 78). A single stage fan section (12) of an engine (10) is connected to the turbine (26) by the shaft (74).
