Which engine component is driven by the energy created in the combustion chamber?

• A. Inlet duct
• B. Compressor
• C. Turbine
• D. Exhaust cone

Answer: (C)

The energy released in the combustion chamber accelerates and expands the hot gases, and the turbine is where that energy is captured. The high-energy gases push on turbine blades, turning the turbine and driving the turbine shaft. That rotation then powers the compressor (and other accessories) of the engine. So the turbine is the component directly driven by the energy created in the combustion chamber. Inlet duct simply guides air into the engine; it doesn’t convert combustion energy. The compressor is powered by the turbine, not by the combustion energy directly, and the exhaust cone is part of the exhaust flow, not a driven component.
