Axial compressors Axial compressorsare much more sensitive to operating conditions and rotor condition than their centrifugal counterparts. Routine washing of these machines is carried out to avoid debris build-up on blades, but this action can also lead to significant erosion of blades, which in tur...

If the hub removal is necessary, such as required on compressors with non-split seals, a tapered hub fit on the shaft should be used. The removable hubs should have tapped puller holes. The shaft should be keyless, with the preferred method of installation and removal by use of hydraulic ...
In axial flow compressors of gas turbine engines it is well known to use either an air bleed valve 34 or a compressor casing treatment to improve the performance of the compressor. Air bleed valves act to keep the working line of the com... RM Ruukasu 被引量: 0发表: 1985年 ...
The modified code was shown to be capable of computing efficiencies that are compatible with those of five multistage compressors and one fan that were tested experimentally. This report serves as a users manual for the revised code, Compressor Spanline Analysis (CSPAN). The modeling modifications,...
Issues concerning the global stabilization of axial compressors are presented. Instead of locally stabilizing the bifurcated rotating stall equilibria to avoid suddern performance drop, control schemes are proposed to globally stabilize the unstalled nominal operating points. These are achieved by employing...

1 Either type can be catastrophic for the performance of compressors (a substantial drop of performance in a stall situation), so predicting the condition for an occurrence of compressor instability is an essential part in the pursuit of both researchers and engineers. The physical description of ...

By comparing the performance characteristics of the two compressors, the loading limit of the two compressors could be determined. Moreover, based on the comparison of the measured inter-blade flow fields, the factors which could restrain the further increasing of loading level of the two ...
