🔍 Key Concepts
• Standard engine orientation (how "left" and "right" are defined on engines and ships)
• How technicians normally describe positions along an engine: forward vs. aft, and looking from which end
• Relationship between combustor, high-pressure (HP) turbine, and power turbine in an LM2500 gas turbine
💭 Think About
• When mechanics say "left" and "right" on an engine, from what usual viewpoint are they speaking? Think of other machinery or shipboard references.
• Picture the flow of air through the LM2500: intake, compressor, combustor, HP turbine, then power turbine. From which component does it make sense to reference directions?
• For the options that mention the combustor, do they correctly place the HP turbine and power turbine relative to the actual gas flow direction?
✅ Before You Answer
• Verify from your study materials how orientation on an LM2500 is officially defined (which direction you are assumed to be facing).
• Double-check the order of major sections: compressor → combustor → HP turbine → power turbine, and which are physically forward vs. aft.
• Make sure the choice you pick is consistent in all three axes: left/right, forward/aft, and how radial is being referenced.
