What is the primary purpose of the diffuser and distributor on the LM2500 GTE?

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

The diffuser and distributor assembly is critical for converting high-velocity compressor discharge air into static pressure while ensuring uniform airflow distribution into the combustor. This uniformity is essential for maintaining stable combustion, preventing localized hot spots, and ensuring even thermal loading across the turbine section during engine operation.
