What is the function of the stator vanes in the compressor section?

• A. To increase velocity and decrease pressure
• B. To decrease velocity and increase pressure
• C. To mix fuel and air
• D. To regulate exhaust flow

Answer: (B)

The function of the stator vanes in the compressor section is primarily to decrease velocity and increase pressure. In a turbine engine, the stator vanes are stationary components that guide the airflow and help in the compression process. As the air moves through the compressor, it passes over these vanes, which are designed to effectively change the direction of the incoming air. When the air flows past the stator vanes, its velocity decreases due to the change in direction, while the pressure increases due to the conversion of kinetic energy into potential energy. This pressure rise is essential for the efficient operation of the engine, as it sets the stage for further compression and ultimately allows for better combustion in the combustion chamber. Therefore, the design and function of the stator vanes are crucial for enhancing the overall performance and efficiency of the turbine engine's compressor section.
