Which two elements comprise the turbine section of a turbine engine?

The turbine section of a turbine engine is primarily composed of the rotor and the stator. The rotor includes the rotating blades that extract energy from the high-temperature, high-pressure gases produced by combustion, converting this energy into mechanical work to drive the engine's components. The stator consists of stationary blades that guide the flow of gases and help convert the kinetic energy of the gases into useful work on the rotor.

Together, the rotor and stator work in tandem to efficiently extract and manage the energy from the exhaust gases. In turbine engines, the interaction between these two elements is crucial for maintaining the proper performance and efficiency of the engine. The rotor captures the energy, while the stator stabilizes and directs the flow, enhancing the engine's overall efficiency.

The other options presented do not accurately describe the core components of the turbine section. For example, while the compressor and turbine are both vital components of a gas turbine engine, they belong to different sections — the compressor being responsible for compressing incoming air and the turbine extracting energy from combustion gases. Similarly, the terms "spar" and "frame" do not refer to elements within the turbine section. Therefore, the correct identification of the turbine section elements as rotor and stator is essential for understanding the engine
