Abstract : This report presents the results of a research program that had two major objectives. The first objective was the development of a prototype rotating stall control system which was tested both on a low speed rig and a J-85-5 engine. The second objective was to perform fundamental studies of the flow mechanisms that produce rotating stall, surge and noise in axial flow compressors and thereby obtain an understanding of these phenomena that would aid attaining the first objective. The work is reported in three separate volumes. Volume 1 covers the fundamental theoretical and experimental studies of rotating stall; Volume 2 covers the theoretical and experimental studies of discrete-tone aerodynamic noise generation mechanisms in axial flow compressors; and Volume 3 covers the development and testing of a prototype rotating stall control system on both the low speed test rig and the J-85-5 engine.
