PROBLEM TO BE SOLVED: To provide power train architectures with low-loss lubricant bearings and low-density materials.SOLUTION: The gas turbine used in these architectures can include a compressor section, a turbine section, and a combustor section. A generator, coupled to a rotor shaft, is driven by the turbine section. The compressor section, the turbine section and the generator each include rotating components, where at least one of the rotating components in at least one of the compressor section, the turbine section and the generator includes a low-density material. Bearings support the rotor shaft within the compressor section, the turbine section and the generator, where at least one of the bearings is a low-loss bearing having a low-loss lubricant.SELECTED DRAWING: Figure 1 |
