In the recent years, a shift from document-based to model-based approaches is going on within many organizations and industries involved in the development of complex systems. Model Based Systems Engineering (MBSE) methods and tools are in fact gaining more and more popularity due to all their claimed benefits over traditional document-based approaches, including for instance enhanced design quality of systems, clearer development of system requirements and specifications and improved communications within the design teams. However, these benefits can be possible only if recommendations on how generating and representing design information during the development process are made available. The present paper introduces a new model-based architectural framework, i.e. a guideline that leverages a modeling approach for the development and representation of complex systems. More specifically, the MBSE architectural framework addressed in this paper focuses on the system architecting activities of a Systems Engineering Product Development process, i.e. when multiple conventional and innovative solutions of the systems are generated to address all the system stakeholder expectations. The proposed architectural framework aims at fostering the agility of the development of complex systems, in order to streamline, improve and accelerate their architectures definition and modeling through an MBSE approach. The paper provides details of the MBSE architectural framework, including the means to produce and represent all the system development information.

“…Model-based approaches to system architecture definition and establishing a link between architecture definition and MDAO form a key part of the AGILE 4.0 toolchain [28,29]. Several studies within the AGILE 4.0 project have also considered certification, thermal risk, and safety assessment aspects within a distributed MDAO workflow [30][31][32]. The AGILE 4.0 project has matured the state of the art in model-based approaches to complex system development.…”

To reduce the environmental impact of aviation, aircraft manufacturers develop novel aircraft configurations and investigate advanced systems technologies. These new technologies are complex and characterized by electrical or hybrid-electric propulsion systems. Ensuring that these complex architectures are safe is paramount to enabling the certification and entry into service of new aircraft concepts. Emerging techniques in systems architecting, such as using model-based systems engineering (MBSE), help deal with such complexity. However, MBSE techniques are currently not integrated with the overall aircraft conceptual design, using automated multidisciplinary design analysis and optimization (MDAO) techniques. Current MDAO frameworks do not incorporate the various aspects of system safety assessment. The industry is increasingly interested in Model-Based Safety Assessment (MBSA) to improve the safety assessment process and give the safety engineer detailed insight into the failure characteristics of system components. This paper presents a comprehensive framework to introduce various aspects of safety assessment in conceptual design and MDAO, also considering downstream compatibility of the system architecting and safety assessment process. The presented methodology includes specific elements of the SAE ARP4761 safety assessment process and adapts them to the systems architecting process in conceptual design. The proposed framework also introduces a novel safety-based filtering approach for large system architecture design spaces. The framework’s effectiveness is illustrated with examples from applications in recent collaborative research projects with industry and academia. The work presented in this paper contributes to increasing maturity in conceptual design studies and enables more innovation by opening the design space while considering safety upfront.

“…However, the research lacks a process comparable to the requirement analysis of a demonstrator. An MBSE approach in [19] implements a certification-driven design for a more complex UAV with a T-tail configuration and a high aspect ratio of 19. The UAV is a full-scale aircraft meeting the airworthiness regulation for large aircraft (EASA CS-25 in this case).…”

MBSE for Civil Aircraft Scaled Demonstrator Requirement Analysis and Architecting

et al. 2022

A civil aircraft scaled demonstrator is an unmanned aerial vehicle (UAV) obtained by reducing the geometry of a civil aircraft by an equal scale and simplifying the airframe and airborne subsystems. Due to the low development cost and flight risk of scaled demonstrators, flight tests with demonstrators are an attractive way to assess the reliability and effectiveness of new configurations and/or technologies available for civil aircraft. Nevertheless, engineers still hope to reduce the development cycles and costs of demonstrators to evaluate their multiple civil aircraft design solutions through flight tests in a short period of time. Model-based systems engineering (MBSE) is a formalized requirement and architecture modeling method which is a useful tool in aircraft design. However, no existing MBSE framework has been found suitable for the development of demonstrators due to their unique features. In this paper, an MBSE approach for civil aircraft scaled demonstrator is proposed based on the MagicGrid methodology and the existing technical process for the demonstrator. This approach formalizes the requirement analysis and architecting for demonstrators via system modeling language (SysML). Meanwhile, the stakeholders of civil aircraft scaled demonstrators are identified, and a requirement ontology and modeling standard are established according to existing demonstrator development practice. Then, a case study is performed through a hybrid power demonstrator which carries a hydrogen fuel cell as the main power supply, a set of solar cells, and two lithium cells. The requirement traceability and verifiability are examined, and a logic simulation is executed for architecture, which shows the feasibility of applying the MBSE approach for the development of civil aircraft scaled demonstrators.
