Research of Multi-disciplinary Unified Model of Aircraft Based on Modelica
Combining the challenges faced in the development process of modern aerospace products represented by aircraft systems,and aiming at the verification and analysis requirements in the overall design stage,this paper uses the multi-professional unified modeling language Modelica to construct the models of the aircraft's main systems.The integrated simulation of the model realizes the verification of the aircraft system in the overall design stage.Based on the constructed aircraft model,real-time code generation was carried out,and then a signal-level real-time simulation system was realized,and a rapid control prototype system simulation experiment was carried out.The work of this pa-per explores and pave the way for the MBSE method in the process of aircraft system design.
