Compressor surge is one of the most worrisome in-flight emergencies that users have to face. The phenomenon is influenced by many parameters internal or external to the engine. The purpose of this paper is to describe an investigation into this matter prompted by the operating experience of the Hellenic Air Force. Initially, the most common destabilizing parameters had to be identified and their influence on engine handling was assessed.The Hellenic Air Force has been facing compressor surge problems, mostly related to the use of the aircraft or the type of mission. The findings of this work give a semi-quantitative explanation of the events observed in practice.Copyright © 1996 by ASME
