Axial flow compressors produce a continuous flow of compressed gas, and have the benefits of high efficiency and large mass flow rate, particularly in relation to their size and cross-section. They do, however, require several rows of airfoils to achieve a large pressure rise, making them complex and expensive relative to other designs (e.g ...
In the axial compressor the air flows parallel to the axis of rotation. Axial compressors are made to be multi-staged. A stage consists of a row of rotating blades called the rotor, which are connected to the central shaft and a row of stationary or fixed blades called stator. In axial flow compressor, the air flows from stage to stage.
In calculating three-dimensional losses, every element affecting a flow path is taken into account—such as axial spacing between vane and blade rows, end-wall curvature, radial distribution of pressure gradient, hup/tip ratio, dihedral, lean, tip clearance, flare, aspect ratio, skew, sweep, platform cooling holes, surface roughness, and off ...
In order to give a compact installation, rather than using an oversized compressor with a bypass around the turbine (as commonly used in the turbofan engine), the Oryx used an auxiliary compressor coupled to the turbine. This was mounted behind the turbine, with its gas flow in the opposite direction to the main engine core. [2]
There is also a third category, called mixed flow machines, where both radial and axial flow velocity components are present. [ 2 ] Turbomachines may be further classified into two additional categories: those that absorb energy to increase the fluid pressure , i.e. pumps , fans , and compressors , and those that produce energy such as turbines ...
Von Ohain's design, an axial-flow engine, as opposed to Whittle's centrifugal flow engine, was eventually adopted by most manufacturers by the 1950s.

Axial compressor animation showing rotating blades and stationary stators The 17-stage axial compressor on the General Electric J79. Air moves from left to right. Each compressor stage is a row of rotor blades which give the air tangential velocity followed by a stationary row of stator blades which slow the air and raise its static pressure.
