Main design & flow features:
• Large scale design: flow path outer diameter is 1 meter.
• Hub to shroud ratio:0.6.
• The blade loading coefficient in terms of mid-span blade speed is 0.35.
• Large scale corner separation at the stator hub, even at the design condition.

Available measurement data includes:
• The compressor static pressure rise and efficiency characteristics.
• The compressor inlet boundary layer.
• The oil-flow visualization on the stator blade surface.
• The flow fields inside the rotor/stator passages.
• The flow fields at the rotor/stator outlets.
