What is the function of the stators in the turbine section of a gas turbine engine?

The function of the stators in the turbine section of a gas turbine engine is primarily to guide the airflow around the turbine. Stators, which are stationary components, play a crucial role in directing the flow of exhaust gases onto the turbine blades. This guidance is essential for optimizing the efficiency of the turbine by ensuring that the gas flow strikes the turbine blades at the correct angle.

By effectively directing the gas flow, the stators help maintain the velocity of the gases, allowing the turbine to convert thermal energy into mechanical energy efficiently. This fine-tuning of airflow is vital for maximizing performance and preventing any disruption that could lead to a decrease in efficiency or performance.

While some other options mention decreasing airflow velocity or preventing backflow, the main purpose of stators is to ensure that gas turbulence is minimized and that gases flow smoothly over the blades, which directly impacts the overall efficiency and effectiveness of the turbine system.
