🔍 Key Concepts

• Compressor stall and what causes it in gas turbine / jet engines • How angle of attack of compressor blades relates to airflow and stalling • The role of bleed valves and multi‑spool compressors in maintaining stable airflow

💭 Think About

• Which options directly reduce the likelihood of the airflow separating from the compressor blades? • Does each option target the same problem (airflow stability) in a different way, or are some unrelated to preventing stall? • Think about whether engineers typically use just one of these design methods or several together in modern engines.

✅ Before You Answer

• For each choice, ask: Does this help keep airflow through the compressor smooth and attached to the blades over a wide operating range? • Consider whether two‑spool compressors and air bleed valves are known design features used to manage compressor stability during acceleration and low‑speed operation. • Double‑check if changing blade angle of attack in the front stages is a recognized way to avoid stall conditions.
