Abstract:

The report is a compilation of four separate papers which, in total, represent a survey of several important aspects of turbine engine performance analysis. The first paper describes a digital computer method which has become a powerful tool for simulation of steady-state engine operation. A discussion of inlet airflow distortion is the topic of the second paper. It elaborates on a theory of rotating stall generation and a unique method which was encountered for determining how this distortion propagates through the compression components and produces surge. The third paper addresses the problems associated with the engine control system and the techniques for computer simulation of transient engine operation. A discussion of the performance predictions of complex multimission aircraft weapon systems comprise the final section of this technical report.
