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 (HP) turbine section is designed as a two-stage axial flow turbine. These stages extract energy from the high-pressure, high-temperature gas stream exiting the combustor to drive the high-pressure compressor (HPC) and the accessory gearbox, maintaining the gas generator's operational cycle.
