Q

Each stage of an axial compressor of a gas turbine can compress the atmospheric air a total of how many times?

🔍 Key Concepts

• Typical pressure ratio per stage in an axial-flow compressor • Difference between overall compressor ratio and per-stage ratio • Practical limits on pressure rise before flow separation/stall occurs in blades

💭 Think About

• Is each stage designed for a very large pressure increase, or many small increases that add up over many stages? • Which option seems more realistic for maintaining smooth airflow and avoiding compressor stall? • How would a high per‑stage pressure ratio affect the required number of stages in a typical gas turbine compressor?

✅ Before You Answer

• Verify typical per‑stage pressure ratio (not total compressor ratio) from standard marine gas turbine references • Check that the value chosen would allow a reasonable number of stages (not just 1–3) to reach common overall ratios like 10:1, 15:1, etc. • Eliminate any option that would likely cause excessive aerodynamic loading on a single stage of blades
