Question 1 of 27070

The gas generator section of the GE LM2500 gas turbine is composed of all of the following components EXCEPT which of the following?

🔍 Key Concepts

• Basic layout of the GE LM2500 gas turbine (airflow from intake to exhaust) • Difference between gas generator section and power turbine/free turbine section • Which components are associated with compression and combustion vs. those that extract power for the output shaft

💭 Think About

• Mentally trace the airflow path: starting at the inlet, through the compressor, combustor, then through which turbine stages belong to the gas generator itself • Ask yourself: which turbine stages are used to drive the compressor (part of the gas generator), and which are used to produce output power to the reduction gear/propeller? • Consider which items are more like inlet/auxiliary hardware versus rotating stages that are truly part of the gas generator core

✅ Before You Answer

• Be clear on the definition of gas generator: it includes the compressor, combustor, and the turbine stages that drive the compressor • Identify which turbine (HP vs LP, and how many stages) is associated with the free power turbine rather than the gas generator • Verify which of the listed items are external intake components and which are internal rotating components of the gas generator core
