A Modelica-based environment for the simulation of hybrid-electric propulsion systems

In this paper, a framework for the modeling of hybrid electric propulsion system architectures for aviation is presented in form of a novel Modelica library. The scope and requirements for an aviation power train modelling framework are specified. The presentation then follows the hierarchical modelling structure of the library. Alongside, key modeling concepts are presented. Finally, the integrated analysis capabilities are highlighted and briefly demonstrated based on classic hybrid power train architecture
