随着飞行器电气系统集成度、功能性的提高,飞行器所处的生存环境也剧烈变化,从以往的常规环境逐步转向真空、高低温、高湿、高功率辐射等恶劣环境下生存,由此系统与环境的兼容性工作问题进一步凸显。为保证系统正常工作,应对上述环境特性进行摸底。本文提出工作在真空、高温环境下的飞行器舱段内的电磁环境的测试方法,并应用该方法,对舱段内的电磁辐射特性进行摸底,验证了热电池激活工作后,在飞行器舱体内产生了电场突变,验证了该方法的有效性。同时,通过对测试数据的分析,提出该测试方法的实施和改进要点。
With the improvement of the integration and functionality of the aircraft electrical system, the living environment of the aircraft also changes dramatically from the conventional environment to the harsh environments of vacuum, high and low temperature, high humidity and high power radiation. Therefore, the system Compatibility issues with the environment further highlighted. In order to ensure the normal work of the system, we should thoroughly understand the above environmental characteristics. In this paper, a test method of the electromagnetic environment in the cabin of an aircraft operating under vacuum and high temperature is proposed. By applying this method, the characteristics of the electromagnetic radiation in the cabin are thoroughly investigated. It is verified that the thermal battery is activated in the cabin of the aircraft The electric field mutation, validated the effectiveness of the method. At the same time, through the analysis of the test data, put forward the implementation of the test method and improvement points.
