What type of combustor is used by the GE LM2500 gas turbine engine?

Correct Answer: Option D — Annular

The GE LM2500 utilizes an annular combustor design. This configuration features a single, continuous combustion chamber ring surrounding the engine axis, which promotes uniform temperature distribution at the turbine inlet, reduces thermal stress on downstream components, and improves overall combustion efficiency compared to individual can-type designs.
