An adjustment testing has been successfully conducted on a 12-stage single rotor axial compressor formed by adding two stages to the front of the original ten-stage subsonic compressor. Tests were carried out for five rows of adjustable guide vanes, based on the relationship of setting angle variation with speed. The test results were compared with the case when fixed geometry configuration was used. With the compressor operating under fixed geometry version there existed in medium speed zone distinct “dual value characteristics, “for which detailed measurements were taken and possible implications discussed. Tests have shown that the use of adjustable guide vanes for improving medium and low speed performance is fully justified.
