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.
