| 摘要: |
| 国内首次承担国产大型客机研制，缺乏机载系统级适航鉴定的技术经验，同时国内外辐射发射研究基本以仿真评估为主，然而仿真结果仅能作为参考，不能在适航鉴定过程中作为符合性证据，并且国内缺少复杂机载系统级的试验经验。以民机飞控电子系统辐射发射鉴定试验为例，将适航符合性需求转化为工程需求，分析民机飞控系统复杂性特征，搭建飞控电子系统级辐射发射试验系统，完善系统级适航鉴定试验和优化过程，为国内外民机复杂系统适航鉴定提供经验。试验结果表明飞控电子系统的辐射发射会因系统试验环境不同而显著变化，同时必须考虑到试验搭建设置对试验通过性的影响，并表明试验符合性满足RTCA/DO-160G要求。 |

| Abstract: |
| It is the first time that domestic civil large aircraft has been developed, which lacks the technical experience of airborne system-level airworthiness qualification, and the research of radiation emission at home and abroad is mainly based on simulation evaluation, while the simulation results are used only as a reference in the airworthiness qualification process and cannot be used as evidence of conformity. And there is little airworthiness test experience on complex system-level. In this paper, taking civil aircraft flight control electronic system as an example, translate airworthiness compliance requirements into engineering requirements, analyze the complexity characteristics of civil aircraft flight control system, build flight control electronic system level radiation emission test system, and improve the system level airworthiness qualification test and optimization process, providing experience for the airworthiness qualification of civil aircraft complex system. The results show that the radiation emission of flight control electronic system is greatly affected by the system environment, and it is necessary to consider the influence of test setup layout and show the system compliance to the RTCA/DO-160G requirements. |
