Abstract
A turbine engine with a turbine core that includes a compressor section having a compressor, a combustion section, a turbine section having a high pressure turbine and a low pressure turbine, and a nozzle section. A high speed shaft couples the high pressure turbine to the compressor. A first gearbox selectively coupling an output of an electric machine and the high speed shaft. A second gearbox couples an input/output of the electric machine and a low speed shaft, where the low speed shaft is coupled to the low pressure turbine.
Claims20
A gas turbine engine, comprising:
- a turbine core comprising:
- a compressor section including a high pressure compressor and a low pressure compressor;
- a combustion section;
- a turbine section including a high pressure turbine and low pressure turbine, where a high speed shaft couples the high pressure turbine to the high pressure compressor;
- a nozzle section;
- a first gearbox selectively coupling an output of an electric machine and the high speed shaft;
- and
- a second gearbox couples an input/output of the electric machine and a low speed shaft, wherein the low speed shaft is coupled to the low pressure turbine, wherein the first gearbox is located axially upstream of the high pressure compressor and the second gearbox is located axially between the high pressure compressor and the low pressure compressor.
