The report summarizes the results of a three year program on rotating stall in axial flow compressors conducted at Calspan Corporation formerly Cornell Aeronautical Laboratory. The work encompassed both experimental and theoretical investigations of rotating stall and the development of a prototype rotating stall control system. The experimental portion of the program included investigation of the effects of blade chord and solidity upon rotating stall properties and inception as well as an investigation of the effect of blade row rotation on blade row performance. In addition, an experiment to determine the stability of the flow through a blade row was conducted. A two-dimensional small-disturbance stability theory was developed to predict the inception of rotating stall. A single balde row and two blade row version of the theory were developed.
