飞机加改装工程中前门耦合干扰的预测与分析方法

Prediction and Analysis Method of Front Door Coupling Interference in Aircraft Modification Engineering

大型飞机加改装无线电设备时,验证和分析加改装无线电设备是否能满足原机的电磁兼容要求,是加改装的关键工作之一,而前门耦合干扰又是电磁干扰的主要来源,为此研究了在飞机加改装工程早期基于仿真和筛选模型对前门耦合干扰进行预测与分析的方法,并根据预测和分析结果进行了加改装方案优化,以降低项目研制的风险。

It is one of the key processes to verify and analyze whether the modified radio equipment can meet the electromagnetic compatibility requirements of the original aircraft when modifying the radio equipment on the large aircraft,front door couplinginterference is the main source of electromagnetic interference.This paper studies the method to predict and analyze the coupling interference of the front door based on simulation and screening model in the early stage of aircraft refitting project,and optimizes the refitting scheme according to the prediction and analysis results,so as to reduce the risk of project development。
