🔍 Key Concepts

• Can-annular combustor construction (individual cans within an outer annular case) • How maintenance is usually done on burner cans/liners in gas turbine engines • Which options would require major teardown versus more limited access work

💭 Think About

• Think about how can-annular combustors are built: do you remove individual cans, or do you have to strip down large engine sections? • Which of these choices sounds like normal, routine access for inspection and replacement of burner units—rather than a full engine overhaul? • For everyday maintenance, which component is designed to allow access without disturbing the entire core or power turbine?

✅ Before You Answer

• Eliminate options that would normally mean a full engine disassembly or overhaul, not routine burner maintenance • Focus on the part that surrounds the individual cans and could be removed or opened to get to each burner unit • Ask: which part is specifically related to the annular outer structure of a can-annular combustor, rather than major rotating sections?
