The design and testing of an axial compressor having a mean stage temperature rise of 30 deg C

Abstract

This report describes a compressor which was designed to give a mean stage temperature rise of 30 deg C. It has six stages so that the overall pressure ratio at the design point is 4.5 : 1. Full details of the factors which led to the form adopted and of the design itself are given in the report. The test results fully substantiated the design assumptions. In particular, using standard design data, it is possible to achieve temperature rises of about 30 deg C without sacrificing unduly any desirable performance features. Such temperature rises were considerably above those being used at the time this work was carried out, and are in fact substantially above the mean value used in present-clay designs. Details of the stage characteristics and the matching of the compressor have been given in the report, together with some other points of special interest.
