Abstract:

This report presents the results of a research program on rotating stall in axial flow compressors and jet engines. The program had three major objectives which were 1 develop an analysis for a three-dimensional, time- variant rotating stall and separation theory, 2 develop analysis for post- stall operationrecovery and aerodynamically induced exotic metal combustion, and 3 consider the effects of distortion, water ingestion, and nuclear blasts on axial flow compressors. The work done towards accomplishing objective 1 is reported in Volume I. The work done towards the accomplishment of the remaining two objectives is reported in Volume II. Volume I contains the description of an implicit time marching Euler code, a small disturbance stability theory for the compressible flow through a compressor stage, and a three-dimensional unsteady lifting surface theory for annular blade rows.
