The power turbine (PT) of the LM2500 GTE has a total of how many stages?

Correct Answer: Option B — Six

The power turbine, or free turbine, of the LM2500 is a six-stage axial flow turbine. This multi-stage design is optimized to convert the kinetic energy of the exhaust gases from the gas generator into mechanical shaft horsepower, providing the necessary torque for marine propulsion applications.
