Axial Compressor

The axial compressor is usually a single inlet, uncooled machine consisting essentially of blades mounted on a rotor turning between rows of stationary blades mounted on the horizontally split casing. A typical unit is shown in Figures 18-103, 18-104 and 18-105. The stationary blades can be either fixed or movable, Figure 18-106. The movable blades allow for better control of and increased flexibility in operations. Figure 18-107 shows a rotor assembly. Most units will have inlet guide vanes for at least the first row of blades and may have exit vanes.
