Experimental Investigation of a Transonic Aspirated Compressor
The experimental investigation of a transonic aspirated stage demonstrating the application of boundary layer aspiration to increase stage work is presented. The stage was designed to produce a pressure ratio of 1.6 at a tip speed of 750ft∕s resulting in a stage work coefficient of 0.88. The primary...

| description | The experimental investigation of a transonic aspirated stage
demonstrating the application of boundary layer aspiration to increase stage
work is presented. The stage was designed to produce a pressure ratio of 1.6 at
a tip speed of 750ft∕s resulting in a stage work
coefficient of 0.88. The primary aspiration requirement for the stage is a bleed
fraction 0.5% of the inlet mass flow on the rotor and stator suction surfaces.
Additional aspiration totaling 2.8% was also used at shock impingement locations
and other locations on the hub and casing walls. Detailed rotor and stator flow
field measurements, which include time-accurate and ensemble-averaged data, are
presented and compared to three-dimensional viscous computational analyses of
the stage. The stage achieved a peak pressure ratio of 1.58 and through-flow
efficiency of 90% at the design point. In addition, the stage demonstrated good
performance with an aspiration lower than the design requirement, and a
significant off-design flow range below that predicted by the computational
analysis. |
