Abstract:
This report provides a means of shortening the compressor design procedure through the use of charts. To facilitate a more rapid procedure, the charts are restricted in application to constant rotor work axial flow compressors. The design charts give the relationships between the mean radius velocity triangle and compressor performance and dimensions. Ranges are established for the variables to include all normal design problems and also to rule out almost immediately all impractical solutions. The charts are generalized with respect to atmospheric conditions to permit greater applicability. That is, the charts may be used for design problems that involve initial atmospheric conditions other than standard and also for multistage compressors by application to each stage in succession. Relationships are established between the mean radius velocity triangle and certain specific compressor parameters such as pressure coefficient, flow coefficient, throttle number and specific speed. Use of the charts is illustrated by the solution of a hypothetical design problem. References are given which provide various methods for determining the blade profiles.
