What occurs in the turbine section of a turbofan engine?

In the turbine section of a turbofan engine, the primary function is to drive the fan and compressor. This is accomplished by extracting energy from the hot gases produced during combustion. As these gases pass through the turbine, they cause the turbine blades to rotate. This rotational energy is then transferred to the fan and compressor, which are mechanically connected.

The turbine's role is crucial because it generates the necessary power to maintain the operational speed of the engine while compressing the incoming air and pushing it through the combustion chamber. This contributes to the overall efficiency and performance of the turbofan engine, enabling it to produce thrust effectively.

In summary, the turbine section is vital for converting thermal energy from the exhaust gases into mechanical energy to drive the fan and the compressor, thus ensuring the engine functions efficiently.
