Which two elements make up the axial-flow compressor assembly?

• A. Rotor and stator
• B. Impeller and diffuser
• C. Stator and vane
• D. Turbine and nozzle

Answer: (A)

An axial-flow compressor relies on alternating moving and fixed blade rows. The rotor carries the blades that spin and impart energy to the air, while the stator has fixed vanes that redirect the flow and convert the kinetic energy into pressure between stages. Because the assembly is made up of these rotating and stationary blade sections, the two elements are the rotor and the stator. The other options mix components from different turbomachinery types or describe stationary parts only, which do not define the axial-flow compressor assembly.
