Abstract:

A test program to evaluate a new transonic axial compressor stage was conducted. The stage was designed by Nelson Sanger of NASA Lewis relying heavily on CFD techniques while minimizing conventional empirical design methods. The stage was installed in the NPS Transonic Compressor Test Rig and instrumented with fixed temperature and pressure probes. A new PC-based data acquisition system was commissioned and programmed for stage performance measurements. These were obtained at 50, 60, 65, 70, and 80 of the design speed before failure of the spinner retaining bolt led to the loss of the stage. The flow through the rotor was analyzed and the rotor performance predicted using a 3-dimensional viscous code RVC3D. The predicted rotor performance agreed qualitatively and was numerically consistent with the measured stage performance.
