The component that directs air into the turbine is called what?

• A. Nozzle guide vanes
• B. Compressor stator
• C. Turbine inlet ring
• D. Fuel nozzles

Answer: (A)

Air must be guided into the turbine in a controlled manner by stationary vanes that shape and direct the flow. This role is fulfilled by nozzle guide vanes, which sit at the turbine inlet to straighten the flow, convert some velocity into pressure, and ensure the gas hits the turbine blades at the proper angle for efficient energy extraction. The compressor stator guides air through the compressor, not into the turbine, and fuel nozzles and other terms don’t describe directing airflow into the turbine.
