Question 1 of 27070

The struts of the GE LM2500 compressor front frame provide passages for all of the following mediums EXCEPT which of the following?

🔍 Key Concepts

• GE LM2500 gas turbine front frame design and function • Differences between fuel oil, lube oil, and scavenge oil systems on a gas turbine • Purpose of seal-pressurization air in gas turbine compressors

💭 Think About

• Think about which systems actually need to be routed through the compressor front frame and why they would pass through the struts • Consider which type of oil is normally used directly for bearing lubrication and which is used for removing or recovering oil that has leaked or migrated • Ask yourself: which medium would most likely be handled by separate external piping rather than through internal strut passages?

✅ Before You Answer

• Identify what the front frame connects and what components are mounted there (e.g., bearings, sumps, accessory drives) • Recall the primary purpose of the lube oil system versus the scavenge function in a gas turbine • Verify which medium would logically require air passages rather than liquid piping through the struts
