某型飞机无线电系统低频接地设计的改进

Improvement on the Design of Low Frequency Grounding for Helicopter Avionics System

以排除某型飞机JT - 9W机内通话系统的交流噪声故障为例 ,介绍了低频接地设计的电磁兼容原则 ,并给出了此型机无线电系统低频接地设计的改进方法。

By taking as an example,the elimination of AC noise in JT-9W intercommunication system of an helicopter,the design principle of EMC in grounding at low frequency bands is recommended and the improved design method for low frequency grounding of the helicopter avionics system is introduced.
