Engine Gas Turbines (Supplementary) USCG Question #106 (Set 4)

What type of combustor is used by the LM2500 GTE?

Official USCG Answer & Rule Citation

Correct Answer: Option C — Annular

The LM2500 utilizes an annular combustor design. In this configuration, a single continuous combustion chamber surrounds the engine axis, providing uniform temperature distribution to the turbine inlet. This design is more efficient and compact than can-type or can-annular systems, promoting better fuel-air mixing and reduced thermal gradients across the turbine.
