Gas Turbines USCG Q#320 (Set 4)

What is the function of the stator in a axial gas turbine compressor?

Official USCG Answer & Rule Citation

Correct Answer: Option B — To convert velocity to pressure.

The stator acts as a diffuser in an axial compressor. By increasing the cross-sectional area of the flow path, it slows the air velocity, effectively converting the kinetic energy (velocity) of the air into static pressure, which is essential for efficient combustion.
