随着民用航空事业的发展,复合材料在飞机上越来越多的应用,在一定程度上降低了机体对外部电磁环境的屏蔽能力,而飞机广泛使用电子电气设备来执行飞行关键和重要功能也对闪电/HIRF防护提出了更高的要求。本文对民用飞机的闪电/高强度辐射场防护保证大纲进行初步探讨,着重介绍飞机闪电/高强度辐射场防护设计的一般方法、保证计划和防护监控。保证大纲与维修大纲共同保证闪电/HIRF防护的有效性,确保飞机在恶劣的电磁环境中能够持续安全的飞行。
With the development of civil aviation, more and more applications of composite materials on aircraft have reduced the ability of the aircraft to shield the external electromagnetic environment to a certain extent. However, the extensive use of electronic and electrical equipment by aircraft to perform the key and important functions of the flight Lightning / HIRF protection put forward higher requirements. This paper carries out a preliminary discussion on the lightning protection / high intensity radiation field protection assurance program of civil aircraft, and focuses on the general method of aircraft lightning / high intensity radiation field protection design to ensure the planning and protection monitoring. Assurance programs and maintenance programs together to ensure the effectiveness of lightning / HIRF protection to ensure that the aircraft in a harsh electromagnetic environment can continue to fly safely.
