The compressor rotor assembly consists of which components?

• A. Compressor blades, the compressor shaft, and the compressor disk
• B. Only compressor blades
• C. Only the compressor shaft
• D. Only the compressor disk

Answer: (A)

The compressor rotor assembly is the rotating part of the compressor and is made up of three essential pieces working as a unit: the compressor blades, the compressor disk (rotor wheel), and the compressor shaft. The blades are the elements that impart energy to the incoming air and create compression. They are mounted to the rotor disk, which provides the structural hub that holds the blades in their exact positions and spacing. The disk is then connected to the shaft, which transmits the engine’s torque to the rotor, causing the whole assembly to spin. Together, these parts form a single rotating assembly, with the blades attached to the disk and the disk mounted on the shaft so rotation drives compression. If any one part were missing, the rotor could not function properly: blades alone lack a mounting base, a disk without a shaft cannot be driven, and a shaft without blades and disk cannot perform compression.
