Description
The digital transformation of engineering processes for space system development is crucial for technological advancement and efficiency in the European Space sector. Our presentation explores Starion, DEKonsult, and OHB's approach to implementing innovative technologies as piloted by the European Space Agency with their Space System Ontology, with a focus on thermal engineering.
Initially, we identified the core processes within the thermal engineering domain across all lifecycle phases, targeting areas most likely to benefit from digitalization. This strategic focus ensures that digitalization efforts address significant pain points and lead to substantial workflow improvements. We developed a Conceptual Data Model (CDM) using NORMA Pro, iterating with stakeholders to capture essential thermal engineering process concepts for both design and analysis, fitting within the broader Space System Ontology developments.
We then translated the CDM into a Logical Data Model (LDM) using SysML version 2 (SysML2), representing complex relationships within thermal engineering in a logical structure. This marks the first use of SysML2 in this context, bridging abstract concepts and practical implementations and enabling specification of example LDM populations for validation use cases.
Finally, we transformed the CDM and LDM into a tangible pilot demonstration by creating a C# class library and implementing a graph database store using dGraph technology. This combination forms the Physical Data Model (PDM), packaged as a plugin module for Starion’s prototype Model Based Engineering Hub. During the activity we also developed tailored UIs for the two selected use cases, as well as a small plugin for ESATAN-TMS to help with automated transfer of relevant information.
