Flow working machine for use in aircraft engine, has main rotor disk or drum driven by main shaft, and auxiliary rotor disk or drum driven by auxiliary shaft, where shafts comprise different rotational speed and/or rotational direction

摘要

The machine has a supporting structure (14) for supporting rotating components of the machine, and a main drive shaft (4) supplying driving power to the machine. A main rotor disk (3) is driven by the main shaft, and an auxiliary drive shaft (9) is arranged coaxial to the main shaft. A rotation speed converting unit transfers a portion of power provided by the main shaft to the auxiliary shaft. An auxiliary rotor disk (6) is driven by the auxiliary shaft, where the main and auxiliary shafts comprise different rotational speed and/or rotational direction.
