Application of an MBSE Approach for the Integration of Multidisciplinary Design Processes

In the current practices of system developments, there is a large gap between systems engineering activities and engineering analyses. In particular, there exists no practical link between architecture-level models, developed using languages such as SysML, and disciplinary models described in specialized tools. In order to close the gap, a capability was developed that integrates SysML models with analysis models. This work discusses application of the capability to the design of an aircraft propulsion system. System requirements and architecture were defined in a SysML model and analysis models were imported to the SysML model to set up parametric diagrams. Engineering analyses were performed from the SysML model to check requirements compliance of the system. When introduced to industry design processes, the technology can streamline requests for engineering analyses from system architecture models.
