Abstract:

The results of a study to determine the unsteady response of an axial flow turbomachine rotor to spatial variations in its inlet flow are presented. This study includes the development of a theoretical analysis which permits the unsteady lift of a blade row to be expressed in terms of the usual blade design parameters. With this solution, which includes the unsteady contribution of the entire blade row, the blade spacing, stagger angle and camber can be selected to give a desired level of unsteady response. Comparisons of this solution with existing solutions for blade rows with specified geometries are presented. Author Modified Abstract
