What section transforms part of the exhaust gas energy into mechanical energy to drive the compressor and accessories?

• A. Rotors and stators
• B. Exhaust section
• C. Turbine section
• D. Accessory section

Answer: (C)

The turbine section is where energy in the hot exhaust gases is converted into mechanical energy. As the high-energy gases expand and flow through turbine blades, they cause the turbine rotor to turn. This rotational energy is transmitted through a shaft to drive the compressor and the accessory gearbox, supplying power to the compressor and attached accessories. The other areas don’t perform this energy conversion on their own: rotors and stators are blade assemblies that guide flow within the engine, the exhaust section is simply the path for exhaust gases, and the accessory section houses gear-driven components but relies on the turbine to provide the energy to turn them.
