| Abstract:In order to solve the problems of unclear forward design process, ambiguous design requirements, and lack of standardiza?
tion in the correspondence between requirement and design and requirement traceability of aeroengine airborne health management system,
based on the comparison of the existing health management functional architecture systems at home and abroad, combined with require?
ment capture, requirement analysis and function allocation in forward design, the top-down forward design process of aeroengine health
management system was studied, and the forward design process platform of aeroengine health management was developed to realize the de?
sign of airborne functional architecture. By introducing model-based system engineering ideas and adopting an object-oriented engineering
design approach, graphical design methods such as functional objective quantification, function description and module definition were es?
tablished to verify the feasibility of this design method in hardware design. By studying the design method of aeroengine airborne health
management system and analyzing the composition of airborne function, an extensible process platform was established, and feasible hard?
ware design models were established using the model-based design method, so as to provide a reference for the design of aeroengine air?
borne health management system. |
