What is the primary purpose of the diffuser and distributor on the GE LM2500 gas turbine engine?

Correct Answer: Option B — To provide uniform airflow to the combustor

The diffuser and distributor assembly is critical for managing airflow exiting the compressor. Its primary function is to reduce air velocity and increase static pressure, ensuring a uniform, stable flow profile enters the combustor section, which is essential for efficient combustion and preventing localized hot spots in the turbine.
