A remote shaft driven open rotor propulsion system with electrical power generation

A system 42 for aircraft propulsion is provided. The system 42 includes a power plant 10. The system also includes an open rotor module 46 operable for rotation. The open rotor module 46 has a plurality of variable-pitch blades 54, 60. The system 42 also includes a first linkage 62 extending between the power plant 10 and the open rotor module 46. The first linkage 62 is operable to transmit rotational power to the open rotor module 46 for rotating the plurality of variable-pitch blades 54, 60. The system 42 also includes an actuator 78 operable to change a pitch of the plurality of variable-pitch blades 54, 60. The system 42 also includes a generator 84 operable to generate electric power. The system also includes a second linkage 86 extending between the power plant 10 and the generator 84. The second linkage 86 is operable to transmit rotational power to the generator 84. The generator 84 is operable to convert the rotational power to electrical power. The system 42 also includes a controller 96 operably coupled to the actuator 78 to vary a pitch of the plurality of variable-pitch blades 54, 60. The controller 96 is also operably coupled to the power plant 10 to adjust a power output. The controller 96 is also operably coupled to the generator 84 to determine demand on the generator. The controller 96 is also operable to vary the pitch of the plurality of variable-pitch blades 54, 60 based at least in part on the demand on the generator 84.
