At which point in an axial-flow turbojet engine are the highest gas pressures typically found?

In an axial-flow turbojet engine, the highest gas pressures are typically found at the compressor outlet. This is because the primary function of the compressor is to increase the pressure of the incoming air before it enters the combustion chamber. As the airflow passes through the stages of the axial-flow compressor, the air is progressively compressed, leading to an increase in both pressure and temperature.

Once the air reaches the compressor outlet, it has been compressed to a pressure that is substantially higher than the atmospheric pressure. This high-pressure air then enters the combustion chamber where fuel is mixed and combusted, creating high-energy gases.

While combustion does occur within the combustion chamber, it is primarily the chemical reaction and thermal expansion of the gases that happens there, rather than an additional increase in pressure compared to the compressor outlet. Therefore, the compression process itself is crucial for establishing the highest pressure point in the engine, which is located just after the compressor.
