Realizing Interoperability between MBSE Domains in Aircraft System Development

Abstract

Establishing interoperability is an essential aspect of the often-pursued shift towards Model-Based Systems Engineering (MBSE) in, for example, aircraft development. If models are to be the primary information carriers during development, the applied methods to enable interaction between engineering domains need to be modular, reusable, and scalable. Given the long life cycles and often large and heterogeneous development organizations in the aircraft industry, a piece to the overall solution could be to rely on open standards and tools. In this paper, the standards Functional Mock-up Interface (FMI) and System Structure and Parameterization (SSP) are exploited to exchange data between the disciplines of systems simulation and geometry modeling. A method to export data from the 3D Computer Aided Design (CAD) Software (SW) CATIA in the SSP format is developed and presented. Analogously, FMI support of the Modeling & Simulation (M&S) tools OMSimulator, OpenModelica, and Dymola is utilized along with the SSP support of OMSimulator. The developed technology is put into context by means of integration with the M&S methodology for aircraft vehicle system development deployed at Saab Aeronautics. Finally, the established interoperability is demonstrated on two different industrially relevant application examples addressing varying aspects of complexity. A primary goal of the research is to prototype and demonstrate functionality, enabled by the SSP and FMI standards, that could improve on MBSE methodology implemented in industry and academia.

Modelica Association Standards and Surrogate Modeling to Enable Multi-Fidelity Simulations

“…The work expands on a simulator that has been successively developed by Saab Aeronautics in order to capture and communicate industrial requirements on Modelica Association Standards, and the corresponding tool support, that jointly provide technology deduced as essential when developing complex systems (Hällqvist, Naeser, et al 2022;Lind and H. Andersson 2011). The simulator in focus, see Hällqvist et al for a detailed description (Hällqvist, Munjulury, et al 2022), incorporates digital artifacts developed in Dymola (Dymola User Manual 2016), OpenModelica (Fritzson et al 2005), Matlab/Simulink, and CATIA. This work adds high-fidelity information, obtained through CFD analysis, conducted with the Altair suite of tools.…”

Cabin Management System Design Based on MBSE

“…To speed up this process, efforts have been made in the past decades to digitalize parts of the design process, and find an approach to support the digitization. [1] [2]In 2007, INCOSE defined MBSE as a formal application of modeling to support system requirements, design, and other activities, And proposed the MBSE vision plan for the first time at the meeting, from 2007 to 2020,MBSE would become a mature theory from a plan. [3]Now an MBSE approach can support the aircraft design from requirements to products.…”
