How many stages are there in the Brayton cycle of a gas turbine?

The Brayton cycle, which is the thermodynamic cycle that describes the operation of gas turbines, fundamentally consists of four key processes: compression, combustion, expansion, and exhaust. However, when discussing the stages of the Brayton cycle, it is common to refer to the individual components involved in these processes in a simplified manner.

In practice, the Brayton cycle can be divided into distinct stages based on how air is compressed, heated, and expanded. This may lead to a breakdown that implies a more complex system or multiple iterations within each main process, but the recognized breakdown generally refers to the four main stages.

When considering applications in practical gas turbine systems, the stages might include additional factors such as intercooling or reheating, which are sometimes factored into more detailed descriptions or specific performance analysis of the cycle. However, in the context of basic gas turbine theory, the main four stages are vital to understanding how the cycle operates.

While the chosen answer suggests five stages, it’s crucial to recognize that different interpretations or expansions of the basic cycle can lead to varied descriptions or classifications. However, in traditional textbook definitions of the Brayton cycle, it typically involves four main processes. This highlights the importance of understanding the fundamental aspects of the cycle while being
