Q

Compressor tip clang can be usually attributed to which of the following operating conditions?

🔍 Key Concepts

• Axial-flow compressor operation and how airflow behaves at different power settings • What happens to compressor blades and airflow during stall or surge conditions • Effect of continuous low-power versus high-power operation on compressor stability and clearances

💭 Think About

• Think about which condition is most likely to cause unstable airflow through the compressor, leading to pressure fluctuations and potential blade vibration or contact • Consider whether mechanical overload alone would make blade tips strike the casing, or whether an aerodynamic problem in the compressor flow is more likely • Ask yourself at which power range axial compressors are most prone to flow separation and stall—near design power or well below it?

✅ Before You Answer

• Identify which choice is directly associated with unstable airflow and flow separation in a compressor • Consider how tip clearance and blade vibration might change at very low versus very high power settings • Rule out options that mainly involve thermal loading or overall engine stress but do not primarily cause short, sharp tip-contact noises (clang)
