Which aircrafts' component is tasked with air compression?

The component responsible for air compression in an aircraft is the compressor. In a jet engine, the compressor is designed to increase the pressure and density of the incoming air before it enters the combustion chamber. This compression is crucial because it allows a greater mass of air to be mixed with fuel, leading to a more efficient and powerful combustion process.

The fan blade, although it plays a role in moving air through the engine, primarily contributes to thrust production and does not compress the air in the way the compressor does. The turbine, on the other hand, extracts energy from the exhaust gases to power the compressor and other engine systems, but it does not perform the function of compression. The flame holder is involved in stabilizing the flame within the combustion chamber but is not related to the compression of the air.

Thus, the compressor is specifically designed to handle air compression, making it the correct answer.
