Abstract:
A test program has been successfully completed to obtain fundamental information concerning the behavior of a fan compressor unit when subjected to planar pressure and flow pulses. Testing was conducted at two corrected fan speeds over a range of input pressure amplitudes and frequencies. A total of 24 fan surges and approximately fifty-seven steady-state data points were obtained. The General Electric developed Planar Pressure Pulse Generator P3G was used to produce a sinusoidal type pressure disturbance to a current technology two-stage fan inlet. A thorough complement of dynamic instrumentation, consisting of approximately 45 transducers, was utilized throughout the testing. Data reduction is complete and several fundamental results have been obtained.
