Q

How many stages are in the HP turbine of the GE LM2500 gas turbine engine?

🔍 Key Concepts

• Basic layout of the GE LM2500 gas turbine (compressor, combustor, HP turbine, power turbine) • Difference between high‑pressure (HP) turbine and power turbine stages • How many stages are needed to drive a 16‑stage axial compressor at high RPM

💭 Think About

• First, recall that the HP turbine’s job is only to drive the compressor via the shaft, not the output reduction gear. How many turbine stages are typically used for that in the LM2500? • Think about whether the LM2500 is a single‑spool or two‑spool engine, and how that affects the design of the HP turbine section. • Compare the likely number of stages in the HP turbine versus the power turbine: which one usually has more stages and why?

✅ Before You Answer

• Make sure you are focusing on the HP turbine stages only, not total turbine stages in the engine. • Confirm from your notes whether the LM2500 has a separate HP turbine and power turbine, and how many stages each has. • Verify that you are not confusing the number of compressor stages (16) with the number of HP turbine stages.
