The function of the compressor in a gas turbine engine is to increase the pressure of the incoming air. This process is critical as it compresses the air before it enters the combustion chamber, which allows for a more efficient and effective combustion process when the fuel is introduced. By raising the pressure, the compressor ensures that there is a higher density of air available for combustion, leading to a more powerful and efficient engine operation.

In typical gas turbine engines, this high-pressure air is essential for maximizing the energy that can be extracted during combustion. The compressor's ability to compress the air significantly impacts the overall performance, efficiency, and thrust output of the engine. Higher pressure within the combustion chamber enhances the combustion process, allowing for a more complete reaction of the fuel-air mixture, which ultimately results in increased thrust production.

The other options refer to functions that are not roles of the compressor: cooling of exhaust gases, burning fuel, or directly providing thrust, none of which align with the primary purpose of the compressor in a gas turbine engine.
