What is the primary purpose of a turbine engine's compressor?

The primary purpose of a turbine engine's compressor is to compress the airflow entering the engine. As the air enters the engine, the compressor increases its pressure and density, which is essential for the subsequent combustion process. By compressing the air, the compressor enables more oxygen to be packed into a smaller volume, allowing for a more efficient and powerful combustion of fuel in the combustion chamber.

This increased pressure and density of the airflow significantly enhance the engine's overall performance, enabling it to produce more thrust. The efficient operation of the compressor is crucial because it directly influences the engine's efficiency and power output, particularly in high-performance applications such as jet propulsion.
