Experience from industry shows that, when developing the support characteristics of a new aerospace system, supportability needs may enter the process too late, leading to difficulties, lack of innovation and a series of constraints to the supportability performance of these systems, mostly when they enter into service and throughout the rest of their life cycles. Therefore, the purpose of this work is to define the Embryo Digital Twin, which is a tool specially designed for the development of all supportability involved in new complex aerospace systems. The procedure followed on this study is to provide a review of the definitions and classifications of digital twins observed in the literature and compare them to the features expected for the Embryo Digital Twin. As a result and to state its relevance, this work presents a high-level model of this tool, clearly positioning it in this context of development.
