Digital mockups have become an integral part of the design of aircraft engines and their environment (nacelle, pylon). In this paper, we show that the conventional physical mockup is not a necessity any more. In fact, the experience of the CFM56-7 design shows that the adjustments required to compensate for the absence of a physical mockup have brought with them a considerable amount of flexibility and reactivity. Thus the deletion of tile physical mockup means a lot more than the corresponding direct savings it generates. Relying solely on the digital mockup is a major change in the design process, and greatly contributes to the global quality of the product.
