The concept of electrification in aircraft has been developed due to the continuous technological advancements in power generation. Electrification enhances the power flow between multi-physical domains for better aircraft performance and efficiency. However, it is complex to analyse the interactions between systems due to the requirement of interconnecting components of various physical domains. Therefore, a model-based design can be designed to reduce the complexity of the system. This design can determine the dynamic states of the multi-physics interaction, provide accurate state estimations, and evaluate the system behaviour of the energy domain. This report studies the use of graph-based modelling concepts to simplify the complexity of designing a multi-physical system, with the addition of its capability to evaluate the dynamic states of the physical domains during interactions between systems. With the use of the principle of conservation of energy, the formulation of graph-based models of aircraft electrical and thermal components is determined and integrated into a dynamic system. Graph-based models simulated in MATLAB/Simulink with Aerospace Power System Toolbox (APST) are used to evaluate the electrical and thermal management systems to evaluate the electrical and thermal management systems. Lastly, a suitable graph-based model of a Hybrid-Electric (HE) aircraft electro-thermal system simulation is analysed.
