中文摘要:

为解决航空发动机机载健康管理系统正向设计流程不清晰、设计需求不明确、需求设计对应及追溯不规范的问题，在对比国内外现有健康管理功能架构体系的基础上，结合正向设计中需求捕获、需求分析和功能分配，研究了由上到下的航空发动机健康管理系统正向设计基本流程，开发了航空发动机健康管理正向设计流程平台，实现了机载功能架构的设计。引入基于模型的系统工程思想，采用面向对象的工程设计思路，建立功能目标量化、功能描述、模块定义等图形化设计方法，验证了该设计方法在硬件设计中的可用性。通过研究航空发动机机载健康管理系统设计方法并分析机载功能组成，建立了可扩展的流程平台，基于模型设计方法建立了可用的硬件设计模型，可为航空发动机机载健康管理系统设计提供参考。

英文摘要:

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.
