To ensure minimum clearance between rotor blade tips and the casing of an axial compressor, manufacturers use which of the following techniques?

🔍 Key Concepts

• Axial flow compressor blade tip clearances in gas turbines • Methods used to allow safe rubbing between blade tips and casing • Difference between precise machining vs. sacrificial/abradable materials

💭 Think About

• Which method allows the clearance to "self-adjust" during operation without causing serious damage if the blades touch the casing? • Which choice sounds like it relies too much on perfect manufacturing versus accommodating thermal growth and deflection in service? • Think about which materials you would want at the blade tip and on the casing if rubbing is expected to occur.

✅ Before You Answer

• Identify which options mention coatings rather than just tight machining • Decide which option uses materials that are intended to wear or abrade safely instead of causing major damage • Ask whether the rotor mounting should be rigid and precise or deliberately loose in a high-speed compressor

Question 1 of 27070

To ensure minimum clearance between rotor blade tips and the casing of an axial compressor, manufacturers use which of the following techniques?

Loosely mounted rotors that expand during use.

Metal-sprayed coating of the casing and squealer tips on the blades.

Closely machined tip to casing clearances.

Abrasive coatings in the casing and hardened tips on the blades.
