ADAPTIVE FAN REVERSE CORE GEARED TURBOFAN ENGINE WITH SEPARATE COLD TURBINE |
| 摘要 |
A turbine engine includes a first fan including a plurality of fan blades rotatable about an axis and a reverse flow core engine section including a core turbine axially forward of a combustor and compressor. The core turbine drives the compressor about the axis and a transmission system. A geared architecture is driven by the transmission system to drive the first fan at a speed less than that of the core turbine. A second fan is disposed axially aft of the first fan and forwarded of the core engine and a second turbine is disposed between the second fan and the core engine for driving the second fan when not coupled to the transmission. |

1. A turbine engine comprising:
a first fan including a plurality of fan blades rotatable about an axis; a reverse flow core engine section including a core turbine axially forward of a combustor and a compressor, the core turbine driving the compressor about the axis; a transmission system driven by the core turbine; a geared architecture driven by the transmission system for driving the first fan at a speed less than the core turbine; a second fan disposed axially aft of the first fan and forwarded of the core engine; and a second turbine disposed between the second fan and the core engine, the second turbine driving the second fan. |
