Abstract
A theoretical investigation of multiple pure tone noise is presented. An analysis based on a two-dimensional inviscid flow model is developed to predict the generation and subsequent evolution of multiple pure tone noise from prescribed blade-to-blade non-uniformities in the rotor geometry. The results show that even small non-uniformities within manufacturing tolerances can be a significant source of multiple pure tone noise. Among the non-uniformities investigated, errors in blade spacing are less significant multiple pure tone noise sources than errors in blade stagger or blade contours.
