新一代分布式IMA核心系统技术研究

Research on new generation of distributed IMA core system technology

为提高飞机作战能力和性能,IMA核心系统将应用于未来飞机的任务组织、功能集成和系统管理.在IMA系统、机载计算研究基础上,提出了一种以时间触发FC(TTFC)网络为统一数据网络的分布式模块化综合航空电子系统(DMIA)架构模型,结合IMA2G系统需求和组成特点分析,进行了新一代IMA核心系统的多核处理、TTFC网络、系统管理与重构关键技术及应用解决方案研究,并通过原型系统研制和试验进行了验证.结果表明:DMIA架构模型及关键技术性能满足系统需求,为新型飞机IMA系统研制奠定基础.

In order to improve the operational capability and performance of aircraft,IMA core system shall be applied in mission organization,functional integration and system management in future aircraft.Based on the studying of IMA system and airborne computing,a Distributed Modular Integrated Avionics(DMIA)architecture model is proposed which takes the Time-triggered FC(TTFC)network as unified airborne network.Combining with analysis of IMA2 G requirement and core composition characteristics,The key technologies and applications solutions in IMA core system including mulit-core processing,Time-triggered FC network,system management and reconfiguration are also studied,and the system is verified by prototype system development and tests.The results show that the DMIA architecture model and key technology performance meet the system requirements,and can be taken as a reference for development of IMA system in the future aircraft.
