Which combustor configuration allows modularity by combining can and annular features?

• A. Tubular
• B. Annular
• C. Can-annular
• D. Separate combustion chambers

Answer: (C)

Modularity in combustor design comes from blending the flexibility of module-type units with the seamless flow of a ring-shaped chamber. A can-annular arrangement places several individual can combustors around the engine’s circumference, yet these cans are integrated into an annular outer casing that distributes air and fuel and collects exhaust into a common annular plenum. This lets you assemble, test, and replace a single can without tearing down the entire combustor, while still maintaining a compact, circumferentially uniform combustion zone. Each can contains its own fuel injectors, igniter, and flameholder, and the cans share the same air supply and outlet plenums that wrap around the ring. The result is easier maintenance and targeted control of performance and emissions per module, along with the smooth, evenly distributed flow characteristic of annular designs. Compared to fully tubular or fully separate-chamber configurations, the can-annular approach provides practical modularity while preserving the advantages of an annular flow pattern.
