‡aMultistage compressors composed of high-pressure-ratio stages have higher over-all off-design efficiencies and a wider operating range than those made up of low-pressure-ratio stages if the blade-row efficiency curves for the two cases are assumed to be somewhat similar.

‡aAn analysis is presented of how the operating range and over-all efficiency of a multistage axial-flow compressor are affected by the off-design efficiency characteristics of the blade row. General analytic expresssions describing the off-design performance of a blade row are presented. These expressions are analyzed and the effects of design pressure ratio per stage and off-design blade-row efficiency on the range are discussed.
