What is one of the primary functions of the turbine in a gas turbine engine?

The primary function of the turbine in a gas turbine engine is to convert the energy from the high-temperature, high-pressure exhaust gases produced during combustion into mechanical energy. This mechanical energy is essential for driving the compressor, which is a crucial component of the engine that increases the pressure of the incoming air before it enters the combustion chamber. Additionally, the energy generated by the turbine contributes to producing thrust, which propels the aircraft forward.

This process of energy conversion and the subsequent use of the mechanical energy for both the compressor and thrust generation exemplifies the fundamental operation of a gas turbine engine, highlighting the turbine's role in maintaining the engine's efficiency and performance.
