A turbine is primarily composed of which two elements?

A turbine is fundamentally composed of a stator and a rotor. The rotor is the rotating part that extracts energy from the high-temperature, high-pressure gas flowing through the turbine, while the stator consists of stationary blades that guide the gas toward the rotor and assist in directing the flow efficiently.

In the design of a gas turbine engine, the interaction between the stator and rotor is crucial for maximizing the conversion of thermal energy into mechanical energy. As the gas expands and moves through the turbine, the rotor blades capture the kinetic energy, causing the rotor to spin. The stator blades play a vital role in directing the flow of gases to ensure optimal performance and efficiency.

The other options do not accurately describe the essential components of a turbine. For instance, while a fan and compressor are important in the overall engine design, they serve different functions compared to the turbine. Similarly, exhaust and intake refer to the gas flow paths in the engine rather than components of the turbine itself. The drive shaft and igniter are also part of the gas turbine system but do not directly pertain to the turbine's primary structure.
