This study involves an analysis of a thermal management system designed for a hybrid-electric aircraft, with the objective of establishing a digital and seamless connection between the system model, developed using Model Based System Engineering, and numerical simulation models. The system overview is provided by Embraer Research and Technology Europe - Airholding S.A, the project partner, which also supplies the Matlab and Simulink numerical models utilized throughout the study. The first step is to conduct an evaluation of the engineering workflow to identify areas for improvement where the above-mentioned connection could enhance the system development process. The subsequent focus of the study is on creating the tool required to establish the seamless connection, which comprises of an MBSE architectural model constructed using the ARCADIA methodology in Capella software, and a digital bridge built with the Python programming language, linking the MBSE model with the Matlab and Simulink models.
