机载设备适航符合性验证电磁环境的构建方法研究

构建机载设备适航符合性验证所需的电磁环境是开展机载设备适航性工作的重要基础条件。分析了适航规章所推荐技术标准DO160E的电磁环境要求,给出了电磁环境模拟的四种基本方法及其构建对象和构建要素,重点研究了数字仿真环境的构建方法,为构建机载设备适航符合性验证电磁环境、开展机载设备适航符合性验证技术研究奠定了基础。

Electromagnetic Environment Constructing Methods for the Airborne Equipment in the Test of Airworthiness

Constructing electromagnetic environment for airborne equipment is one of the most important basic conditions in the process of its airworthiness. The requirement of the constructing electromagnetic environment is deduced with DO160,which is suggested by some airworthiness documents. Four typical constructing methods, ob- jects and elements are given to test the electromagnetic environment airworthiness of airborne equipment. The con- struction method of the digital simulation is mainly shown to establish the airworthiness test＇ s electromagnetic envi- ronment for the airborne equipments.
