🔍 Key Concepts

• Compressor stall in gas turbines is closely related to the angle of attack of the air on the compressor blades • Think about what happens if air hits an airfoil (like a wing or blade) at too great an angle versus too shallow an angle • Distinguish between what happens in the compressor section versus the turbine section of a gas turbine engine

💭 Think About

• Which answer choices refer specifically to compressor rotor blades and which refer to other parts of the engine (like turbine blades or foils)? • How does changing the angle at which air strikes a rotor blade affect whether the airflow stays smooth (laminar) or becomes separated/stalled? • In aerodynamics, when does an airfoil usually stall: when its angle of attack is too low, or when it becomes too high and the airflow separates?

✅ Before You Answer

• Make sure the option you choose mentions the compressor (not turbine or general foil section) • Confirm that your choice involves an angle of attack problem that would cause air to separate from the blade surface • Verify whether stall is typically associated with an angle being too high or too low in basic airfoil theory

Question 1 of 20

Which of the following could cause compressor stall?

Air flow over the lower foil section becomes turbulent and destroys the pressure zone.

The angle at which the hot gases strike the turbine rotor blades is too high.

The angle at which the air strikes the compressor rotor blades is too low.

The angle at which the air strikes the compressor rotor blades is too high.
