The factors influencing the design of the ALF 502 engine are reviewed in context with explanations and some retrospective comments.Early experiments are outlined, followed by a more detailed account of the intense short-term development which culminated in the Pre-Flight Rating Test.The conclusion reached is that, in the 6000 to 8000 lb. thrust class, the economy and rapid availability achieved by combining a carefully tailored fan module with a simple, well proven core engine of modest pressure ratio can outweigh the advantages of higher cycle efficiency obtainable with a more complex machine.
