books.google.com.pk - At design loading, the change in stage efficiency with vane clocking was 0.27 points between the maximum and minimum efficiency clocking configurations. The maximum efficiency configuration was the case where the Stator 1 wake impinged on the Stator 2 leading edge. This condition produced a shallower...http://books.google.com.pk/books/about/Vane_Clocking_Effects_in_an_Embedded_Com.html?id=5He3negTRk0C&utm_source=gb-gplus-shareVane Clocking Effects in an Embedded Compressor Stage
