Model Based Design and Integration of More Electric Aircraft Systems Using Modelica

Abstract

The development of future more-electric air-craft systems is a challenging process: The respective subsystems are highly integrated to achieve an optimum efficiency and per-formance both at aircraft and at systems level. For mastering this multi-disciplinary challenge, the use of powerful modelling and simulation technologies such as Modelica in all phases of the system development proc-ess is a key success factor. In this paper, new modelling and simulation methods and tools for the different tasks of the design process are presented. This in-cludes the optimisation of the electric network architecture, detailed design and assessment w.r.t. network stability, health status and power quality, as well as system integration using virtual testing.
