Aeroacoustic Phenomena In High Pressure Centrifugal Compressors - A Possible Root Cause For Impeller Failures. Konig, Sven; Petry, Nico; Wagner, Norbert (Texas A&M University. Turbomachinery Laboratories, 2009)During the past decades studies of aeroacoustic phenomena in turbomachinery were mainly carried out by research institution. The aerospace industry was the main driver in this field since noise issues gained more and more ...
ON-SITE DETERMINATION OF THE CONTROL LINE FOR INTEGRALLY GEARED COMPRESSORS FOR AVOIDANCE OF IMPELLER FATIGUE FAILURES Wagner, Norbert; Konig, Sven; Winkes, Georg; Sub, Stefan (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)In this lecture a root cause analysis (RCA) is presented for a fatigue failure of a semi-open impeller of an integrally geared compressor. The compressor had been in service for about one year in an air separ 3rd stage impeller.
