In order to increase the working range and the maximum weight flow of electric motor driven axial flow compressors with variable stators at each stage for use in blast furnace application, a model unit of the compressor with two-stage variable stator having a relatively small hub-tip ratio was constructed and tested, and its performance characteristics with variable speeds and variable stators were measured and compared with the predicted performance. The tests were carried out up to the peripheral velocity of 1070 fps and stator setting angles of from 20 to −20 deg from design. The tests generally showed the results expected, but surge had risen much earlier than predicted, and the performance near the hub was not satisfactory.
