What is the purpose of the turbine stator in a gas turbine engine?

The turbine stator plays a critical role in the operation of a gas turbine engine by increasing the velocity of exhaust gases. After the hot gases exit the combustion chamber and pass through the turbine, they flow through the turbine stator vanes. These stationary vanes are carefully designed to direct and accelerate the flow of exhaust gases as they pass through.

When the gases hit the turbine stator, their path is altered, and as a result, the energy from the high-speed exhaust flow is converted into rotational energy. This process maximizes the efficiency of converting thermal energy into mechanical energy, allowing the engine to produce thrust. The increased velocity of the exhaust gases enhances the overall performance of the engine, contributing to the thrust generated.

In summary, the turbine stator's design and function are essential to harnessing the energy in the exhaust and significantly boosting the velocity of the gases, which is crucial for the efficient operation of a gas turbine engine.
