Abstract
Successful compressor aerodynamic performance can be achieved by satisfactory completion of requirements in the following three areas:
aerodynamic design
quality of blading
manufacturing and assembly of the components
Using presently available computer programs capable of doing detailed three dimensional analysis of the flow field, it is possible to obtain excellent aerodynamic designs exceeding 90% isentropic efficiency.
When the design requirements are deviated from the manufacturing process, the result will be less than optimum performance, for example: inadequate surge margin, lowered efficiency, reduced mass flow, etc. may be experienced.
Different types of manufacturing deviations and their effect on compressor performance are analysed in the paper by means of empirical formulas and considerations.
