基于 MBSE 的新一代航空发动机总体-部件多学科协同模式

To address the challenges of collaborative difficulties and multi-disciplinary simulation integration in design, a model-based systems engineering (MBSE) methodology was adopted to construct a requirements-function-logic-physical (RFLP) system engineering framework and develop an efficient decomposition-synthesis model for system-component relationships, enabling streamlined modeling and management. Through the development of requirement item management, systems modeling language (SysML) visualization modeling tools and component-embedded simulation solutions supported by integrated performance solvers, a multi-disciplinary collaborative design platform was established, so that a complete forward design process for aero-engines based on MBSE was achieved, and a browser/server (B/S) architecture environment supporting multi-institute, multi-disciplinary and multi-team collaboration was built, providing an efficient and reliable solution for aero-engine design. The platform supported lightweight visualization, management, and traceability of three-dimensional structural models, and implemented a forward design workflow through departmental permission management and approval processes. Using a high-bypass dual-variable cycle engine as a validation example, the platform improved the design accuracy and reduced redundant work; SysML visual modeling provided a solid foundation for subsequent simulations; multi-disciplinary simulation integration and multi-scheme comparison accelerated design iteration speed; and the three-dimensional structure management module enhanced model review and optimization efficiency.
