What occurs in the turbine section of a turbofan engine?

In a turbofan engine, the turbine section plays a critical role in converting high-temperature, high-pressure exhaust gases into mechanical energy. This energy is then used primarily to drive the fan and the compressor. As the exhaust gases pass through the turbine blades, they cause the turbine rotor to spin. This rotational energy is harnessed to maintain the operation of the fan and the compressor, which are essential for delivering the necessary airflow and maintaining the engine's performance.

The design ensures that while the exhaust gases exit the engine, they also play a significant role in the overall propulsion system by powering auxiliary components. Therefore, the function of the turbine section is integral to the efficiency and effectiveness of the turbofan engine, enabling good thrust while keeping fuel consumption in check. This interconnected operation enables the engine to propel the aircraft effectively while maintaining operational efficiency.
