Question 3Gas Turbine - Assistant Engineer

The correct answer is D) Intake, compression, combustion, expansion, exhaust. The Brayton Cycle, which is the operating cycle for gas turbine engines, consists of these five key stages: 1. Intake: Air is drawn into the engine. 2. Compression: The air is compressed, increasing its pressure and temperature. 3. Combustion: Fuel is injected and ignited, causing a rapid expansion of the gases. 4. Expansion: The high-pressure, high-temperature gases expand through the turbine, producing mechanical work. 5. Exhaust: The expanded gases are expelled from the engine. The other answer choices do not accurately describe the complete Brayton Cycle. For example, option A omits the compression and expansion stages, while option B includes an "explosion" stage, which is not part of the Brayton Cycle.
