How many stages are in the HP turbine of the LM2500 GTE?
Official USCG Answer & Rule Citation
Correct Answer: Option B — Two
The LM2500 high-pressure turbine section is engineered with two stages to extract sufficient energy from the combustion gases to drive the high-pressure compressor. This two-stage configuration is a hallmark of the LM2500 design, balancing thermodynamic efficiency with the mechanical requirements of the gas generator rotor assembly.
