What are the two main types of turbine compressors?

• A. Radial flow and axial flow.
• B. Centrifugal flow and tangential flow.
• C. Centrifugal flow and axial flow.
• D. Axial flow and mixed flow.

Answer: (C)

Two main ways air is pressurized in turbine compressors are axial-flow and centrifugal (radial) flow. In an axial-flow compressor, air moves parallel to the engine axis as it passes through multiple stages of rotating blades (rotors) and stationary vanes (stators). Each stage adds a small amount of pressure, so you stack many stages to reach the desired overall pressure. This setup handles large volumes of air efficiently and is common in modern jet engines because of its high flow capability and good efficiency at large scales. In a centrifugal flow compressor, air enters the center of a spinning impeller and is flung outward by centrifugal force into a diffuser, where velocity is converted to pressure. A single stage can produce a large pressure rise in a compact form, making centrifugal designs useful when space is limited or for smaller engines, or as booster compressors. They typically handle lower axial flow than an axial compressor of the same size but are simpler and robust. Thus, the two primary types are axial-flow and centrifugal-flow compressors. Tangential or mixed-flow configurations exist but are not the main categories used in most turbine compressor designs.
