What is the primary function of the compressor in a turbine engine?

• A. Increase the pressure of the incoming air
• B. Decrease the velocity of the incoming air
• C. Increase the temperature of the air
• D. Filter the incoming air

Answer: (A)

The essential function of the compressor in a turbine engine is to raise the pressure of the incoming air. By compressing the air, the engine increases air density, which allows more air to enter the combustor and mix with fuel for efficient and powerful combustion. The higher pressure also helps the subsequent turbine stages extract energy more effectively and improves overall thrust. While compression does raise temperature as a byproduct, the primary goal is increasing pressure (not filtering air or primarily reducing velocity). Filtering air is handled by inlet systems, and decreasing velocity is not the compressor’s main purpose.
