This paper presents a demonstrator implemented in the project MISSION (Modelling and Simulation Tools for Systems Integration on Aircraft). This is a collaborative project being developed under the European Union Clean Sky 2 Program, a public-private partnership bringing together aeronautics industrial leaders and public research organizations based in Europe. The provision of integrated modelling, simulation, and optimization tools to effectively support all stages of aircraft design remains a critical challenge in the aerospace industry. In particular the high level of system integration that is characteristic of new aircraft designs is dramatically increasing the complexity of both design and verification. Simultaneously, the multiphysics interactions between structural, electrical, thermal, and hydraulic components have become more significant as the systems become increasingly interconnected. This demonstrator shows the first level of integration of different models and tools proposed in MISSION framework. In particular an electromechanical actuator with the related control logic will be proposed as system under test; the plant systems will be natively physical modeling based on Modelica and the causal control system will be natively a Simulink model. The simulation platform VEOS from dSPACE is applied to run tests of the controller by making use of plant implementations. In this scenario, a virtual CAN bus simulates the controller communication, while different tools are used to visualize simulation results. The electronic controller will simulate in a specific tool for embedded systems simulation (Desyre). The same models will be exchanged and used in - both the Modelica tool SimulationX and Simulink environment for Model-in-the-Loop testing, - VEOS for Software-in-the-Loop testing and - Desyre for Virtual-Processor-in-the-Loop testing. The paper will highlight the workflows to perform the various stages of virtual testing and the proposed way to exchange artifacts within the modelling and analysis framework. The alignment of the simulation results will demonstrate the successful integration and additionally some tool specific results and metrics will be illustrated.
