What describes Brayton's Cycle?

Brayton's Cycle is characterized by a repetitive process in which combustion occurs at a constant pressure. This is fundamental to the operation of gas turbines, where air is compressed, mixed with fuel, and then ignited. The combustion takes place in a combustion chamber, allowing the gases to expand and do work on the turbine. The constant pressure combustion process helps to maintain efficiency and manage the thermal dynamics of the cycle effectively.

This constant pressure feature allows for the maximum extraction of energy from the combustion process, leading to effective conversion of fuel to mechanical power as the expanding gases do work on the turbine blades. The repetitive nature of the cycle refers to the continuous intake of air, compression, combustion, and expansion, which is crucial for sustained operation in gas turbine systems.
