Abstract: A digital computer model was given to simulate the post stall operation of the axial compression system in a turbine engine The major engine components such as the high pressure compressor , primary combustor and turbine were modeled based on stage by stage dynamic compression system modeling technique The surge characteristics for the compression system was presented,and the recovery from the surge in the compression system was obtained using primary combustor fuel cutoff control schedule It was found that the fuel cutoff rate was the significant controlled parameter for the compression system recovery It was notable that inlet total temperature of the turbine was considerably decreased with the fuel cutoff control plan
