What is the primary function of the compressor section?

• A. It heats the air
• B. Primary function to supply air in sufficient quantity to produce the required engine thrust
• C. It stores fuel
• D. It cools the engine

Answer: (B)

The main idea is that the compressor section is all about delivering air at the right pressure and in sufficient quantity to enable the engine to produce the required thrust. By increasing the air pressure and maintaining an adequate mass flow, the compressor ensures the combustion chamber has enough high-energy air to mix with fuel and burn efficiently, which drives the turbine and ultimately creates thrust. While compression does raise air temperature, that heat is a byproduct, not the purpose of the compressor. The other options don’t fit because storing fuel or cooling the engine aren’t functions of the compressor, and heating the air isn’t its primary goal.
