Axial compressors are flow devices by which the air flows in alternating in an axial direction through a series of rotating and stationary paddles.

The air is first accelerated and then compressed. The paddle ducts form randomly expanded channels in which the kinetic energy generated by circulation of the air delays and is converted into pressure energy.
