<p>PURPOSE: To reduce flow resistance and weight of a transmitting device by connecting two coaxial shafts on which a working turbine is mounted to a propfan rotor upstream of a gas turbine. CONSTITUTION: Two contra-rotating turbine rotors 5a, 5b are mounted on two coaxial shafts 6, 7. The shafts 6, 7 penetrate a gas turbine 11 of a gas generator 4, and are each connected to a respective propfan rotor 2, 3. The propfan rotors 2, 3 are surrounded by a casing 12. Thus, it is possible to reduce flow resistance and weight of a transmitting device.</p> |
