摘要
直9系列直升机是在法国海豚直升机国产化基础上改进改型形成的快速轻型多用途双发直升机,已生产了十余个型别,是国产直升机的主要机种。经过改型后的直9系列直升机安装了更多的先进机载电子设备和任务设备,设备的信号传输依赖于机载数据传输电缆,数据传输电缆之间的电磁干扰会导致设备不能发挥正常功能,影响了直升机的安全运行和能力发挥。通过对直9系列直升机机载数据传输电缆的仿真分析计算,得到了电缆回路之间的距离、屏蔽层厚度、布线方式与电磁耦合之间的关系。为同类的直升机/飞机的机载数据传输电缆优化布线及电磁兼容设计提供一定参考依据。
Z9 series helicopter is a kind of light multipurpose helicopter with double engines, the prototype model is from France DOLPHIN helicopter. Z9 series helicopters have been domestically produced and have been modified and improved more than 10 models as the main helicopter of China. However the modified and improved Z9 series helicopters have been equipped more and more advanced avionics and complicated mission equipment, the transmission of equipment signal depends on the airborne data transmission cables, electromagnetic interference(EMI) between data transmission cables would cause the device invaliding, affect the ability and safe of helicopter. In this paper, the relationship of the distance between cable loops, the thickness of the shield, wiring and the electromagnetic coupling are calculated and simulation analyzed. This research would provide reference for wiring optimization and electromagnetic compatibility(EMC) design in similar helicopter or aircraft.
