The Brayton Cycle is a series of events best described by which of the following statements?

Correct Answer: Option D — Intake, compression, combustion, expansion, exhaust.

The Brayton Cycle defines the thermodynamic process of a gas turbine: intake of air, compression to increase pressure, combustion to add heat at constant pressure, expansion through the turbine to extract work, and final exhaust. This cycle is the fundamental operational basis for all modern marine gas turbine propulsion systems.
