Two functions of the compressor stator vanes include which of the following?

Correct Answer: Option A — Direct air flow to each rotor stage at the correct angle and deliver air to the combustor at the correct velocity and pressure.

Stator vanes serve two primary functions: they redirect airflow to the subsequent rotor stage at the correct incidence angle and act as diffusers to convert kinetic energy into pressure energy, ensuring the air reaches the combustor at the required velocity and pressure.
