A major portion of the Life Cycle Cost (LCC) of a modern high technology weapon system is determined by design decisions made very early in the development process. Many of these decisions are so fundamental that later changes become impractical. As a result, a usage-sensitive, interactive aircraft engine LCC model has been developed by Pratt & Whitney Aircraft to evaluate and prioritize potential technology candidates during conceptual/preliminary design. This paper discusses the development of the EAGLE (Engine/Airframe Generalized LCC Evaluator) model, its validation using results from the Advance Technology Engine Studies (ATES), and includes an example engine technology evaluation.
