Analysis and Design of Civil Aircraft Brake Cooling System Based on MBSE

As the complexity of civil aircraft systems improves and their requirements for safety and reliability become more stringent. The civil aircraft system design process presents characteristics such as multiple stakeholders, complex scene conditions, coupled functional interactions, difficulty in defining requirements, and difficulty in integration, when designing the Brake Cooling System, through the MBSE method and System Modeling Language(SysML) to conduct stakeholders analyses, usescases analysis, lifecycle analysis, needs analysis. Establishing a more realistic Functions&Functional interactions model to capture functional requirements can help aircraft designers design and evaluate key design points, such as system architecture trade-offs, functional requirements capture and confirmation in the early stages of design.
