🔍 Key Concepts

• GE LM2500 gas turbine basic layout: gas generator vs. power turbine (PT) • Difference between compressor stages and turbine stages • How many stages are in the PT section only, not the entire engine

💭 Think About

• First, recall the major sections of the LM2500 and which one actually drives the ship’s reduction gear and shaft. • Think about how many turbine stages belong to the gas generator versus how many are in the free power turbine (PT). • Eliminate any answers that sound more like the total number of turbine stages in the whole engine rather than just the PT.

✅ Before You Answer

• Verify you are counting only the power turbine (PT) stages, not compressor or gas generator turbine stages. • Confirm from your mental diagram or notes how many free power turbine wheels/rotors are downstream of the gas generator. • Be sure you are not mixing the LM2500 with other models (e.g., LM2500+ or LM6000) that may have a different PT stage count.
