🔍 Key Concepts

• Relationship between centrifugal-flow compressors and early gas turbine designs • Basic shapes of combustion chambers: can, annular, can-annular • Which combustion chamber types are more common in axial-flow vs centrifugal-flow engines

💭 Think About

• Think about older, simpler gas turbine designs that used centrifugal compressors—what combustion chamber layout was easiest to manufacture and maintain? • Which combustion chamber style groups several small, self-contained chambers around the engine, instead of one continuous ring? • Which designs (annular / double-annular) are usually associated with high-performance axial-flow aircraft engines rather than simple marine/industrial turbines?

✅ Before You Answer

• Identify which option describes multiple separate chambers instead of one continuous ring • Eliminate the choices that are primarily used in modern high‑bypass or low‑emission axial‑flow engines • Match the simplicity and maintainability of centrifugal-flow engines with the combustion chamber type most commonly paired with them
