What is the purpose of the compressor in a gas turbine engine?

The purpose of the compressor in a gas turbine engine is to increase the pressure of the incoming air. This increase in pressure is crucial for the engine's performance, as it ensures that there is a sufficient amount of oxygen available for combustion when the fuel is introduced. The compressor's role is vital to achieving the high temperatures and pressures needed to facilitate efficient combustion in the combustion chamber. By compressing the air, the engine is able to maximize the energy extracted from the fuel, ultimately enhancing thrust and overall efficiency.

The compressor operates by drawing in ambient air and sequentially compressing it through a series of rotating and stationary blades. This not only raises the pressure of the air but also increases its temperature. The compressed air then flows into the combustion chamber, where it mixes with fuel and is ignited. This process is fundamental to the functioning of gas turbine engines, which rely on the conversion of thermal energy from combustion into mechanical energy for propulsion.
