    The utilization of axial-flow compressors (Fig. ) in gas-turbine engines has been relatively recent. The history of this compressor type began following an era when centrifugal compressors (Fig. ) were dominant. It was later confirmed, on an experimental basis, that axial-flow compressors can. (The turbocharger in many sports cars is composed of a centrifugal compressor and turbine.) The other type of compressor is the axial flow compressor. While axial compressors can accomodate more airflow than a centrifugal design of the same size, a rotor/stator stage generally does not provide enough compression for most applications. moving blades. In the analysis of the highly efficient axial flow compressor, the 2-D flow through the stage is very important due to cylindrical symmetry.

The compressor design configuration utilizes low aspect ratio/highly-loaded axial compressor blading combined with a centrifugal backend stage tomore» Initial testing of the compressor test rig was conducted with a vaneless centrifugal stage diffuser to allow documentation of the axial compressor performance.

    Axial compressors are used in applications where high mass flow rates are required. Axial compressors are exclusively used in jet engines of higher thrust. Also in land based gas turbines used for power generation. A few facilities in the world ha.
