Landing gear system design for aircraft based on SysML v2 and MBSE

Abstract The design of modern aircraft systems demands a robust framework to address escalating complexity and interdisciplinary integration challenges. Traditional engineering practices, reliant on SysML v1, struggle with semantic ambiguity, manual parameter adjustments, and limited model reusability, which hinders efficient collaboration across projects. This paper introduces a Model-Based Systems Engineering (MBSE) framework enhanced by SysML v2, the latest iteration of the Systems Modeling Language, to overcome these limitations. By applying the methodology to the safety-critical aircraft landing gear system, this paper presents a comprehensive MBSE-based modelling approach covering multi-level requirement capture, scenario-driven analysis, system structuring, and action modelling. Besides, we demonstrate how SysML v2’s definition-usage paradigm, parameterized constraint modelling, and automated inheritance mechanisms enable scalable and traceable system design. Furthermore, the promoted methodology in this paper enables efficient reuse of historical models and reduces manual modification efforts. This work establishes a foundation for agile, full-lifecycle MBSE practices in aerospace engineering, offering a scalable solution for complex system design to foster cross-disciplinary interoperability.
