Abstract : Unsteady and distorted flows which have been experienced at the inlet of turbojet and turbofan installations in aircraft have often limited the operating range of the propulsion systems. This program was undertaken to better understand and to find solutions to the effects on the engine caused by these unsteady and distorted flows. It was a multiphase program based on experimental and theoretical approaches, which involved study of: unsteady and distorted flow through fans, cascades and compressors; means to isolate and identify meaningful engine data for detailed analysis; ways to produce desired unsteady and distorted flows at the inlet for testing purposes; and how to assess the effects of these unsteady and distorted flows on combustion stability and burning limits of engines.
