Abstract
A device drives auxiliary machines by using power extracted from a multi-shaft gas turbine engine. The gas turbine engine may include a LP shaft and a HP shaft. The machines may be installed in a gearbox. The device may include a first mechanical transmission between the HP shaft and the gearbox. The device also may include a hydraulic transmission between the LP shaft and the gearbox. Further, the LP shaft connects a low pressure turbine to a low pressure compressor, the HP shaft connects a high pressure turbine to a high pressure compressor, and the low pressure compressor is upstream of the high pressure compressor.
Claims16
A device for driving auxiliary machines of a double-shaft gas turbine engine, the engine including an LP shaft and an HP shaft, said machines being installed in a gearbox, and the device comprising:
- a first mechanical transmission between the HP shaft and said gearbox;
- and
- a hydraulic transmission between the LP shaft and said gearbox, wherein the LP shaft connects a low pressure turbine to a low pressure compressor, the HP shaft connects a high pressure turbine to a high pressure compressor, and the low pressure compressor is upstream of the high pressure compressor.
