A compressor used in gas turbine engines in which the flow of air is maintained parallel to the compressor shaft. An axial-flow compressor is made up of several stages of alternate rotors and stators. The number of stages of compression determines the compression ratio. An axial flow has high efficiency in that it has lower fuel consumption at a given power and a higher compression ratio. It can cater for a large mass flow and, hence, is suitable for high-powered engines.

The possibility of using turbine-type compressors across the entire range of inlet pressures from high vacuum to atmosphere was recognized from the very beginning when the axial-flow compressor was evaluated as a high-vacuum pump and the potential usefulness of centrifugal and peripheral-flow regenerative blowers was considered.
For example, GE engineers are developing a high-efficiency 18-stage axial-flow compressor for the 7EC that adds a zero stage to the 7EA compressor design, increasing mass flow from 664 pounds per second in the 7EA to 769 pounds per second in the 7EC and the pressure ratio from 12.
They accomplished this by designing a high-efficiency axial-flow compressor and six can-type combustors, and by providing the new turbine with a high inlet temperature.
Paul Bladon, before his sad death in 2008, pioneered the machining of minute axial-flow compressor blade discs--blisks-from solid material using electrodischarge machines (EDMs).
A multi-stage axial-flow compressor is followed by a single-stage radial compressor feeding air into the reverse-flow combustion chamber.
Paul Barrett, co-founder and chairman of Bladon Jets, says: "Successful miniaturisation of the axial-flow compressor has been the key to what we are doing.
Axial-flow compressors are advanced turbo-compressors used for high capacities.
The portfolio of compressors contains axial-flow compressors, single shaft compressors as well as gear type compressors that are chosen in dependence on the customer's requirements and layout of the plant components.
