What is the correct sequence of events to sustain operation in a gas turbine engine?

The correct sequence of events to sustain operation in a gas turbine engine is indeed captured in the choice of intake, compression, expansion, and exhaust.

In a gas turbine engine, the process begins with intake, where ambient air is drawn into the engine. This air is crucial as it is the working fluid that will be compressed and later expanded to produce thrust. After intake, the air undergoes compression, which increases its pressure and temperature significantly. This is accomplished in the compressor section of the turbine, which pushes the air into a denser state, priming it for the next step.

Following compression, the compressed air moves to the combustion chamber, where fuel is injected and ignited, creating a high-temperature, high-pressure gas. This gas undergoes expansion in the turbine section, where it passes through turbine blades, causing them to spin. This spinning motion is what effectively powers the compressor (and any engines connected to it) and provides thrust.

Finally, the remaining gases that have gone through the expansion phase are expelled through the exhaust system, completing the cycle. This entire sequence is vital for the continuous operation and efficiency of the gas turbine engine, ensuring that energy is harnessed from combustion to produce mechanical work.
