Which type of combustion chamber is primarily used on engines equipped with a centrifugal compressor?

The combustion chamber primarily used on engines equipped with a centrifugal compressor is the can combustion chamber. This design features multiple combustion cans arranged around the engine, each containing its own fuel injector and combustion zone. This configuration is advantageous for centrifugal compressors as it allows for the effective mixing of fuel and air, which is crucial given the higher pressures generated by these compressors.

The can design has been widely utilized in older jet engines and provides ease of maintenance, as individual cans can be serviced or replaced without affecting the entire combustion system.

In contrast, an annular combustion chamber, while used in some engine types, is typically associated with axial flow compressors. It features a continuous ring-shaped design, which provides a larger surface area for improved combustion efficiency but may not align as well with the flow characteristics of a centrifugal compressor.

Terms like "combustor" or "chamber" are too broad and do not specifically indicate the arrangement or function relevant to centrifugal compressors, which is why they do not provide the correct context for this question.
