舰载飞机电线电缆选用技术分析

Analysis of Selection for Wires and Cables in Shipboard Aircraft

舰载飞机与岸基飞机相比,对全机电线电缆的选用提出了新的要求。根据舰载飞机服役的环境和技术要求,重点在于海洋环境对航空电线电缆的特殊耐受性要求,以及飞机自身对减重所提出的最大化可能性,结合航空电线电缆的国内外发展现状,提出舰载飞机全机电线电缆的选用方案,即常温区选用辐照交联ETFE绝缘电线电缆、高温区选用光滑无缝绕包PI/PTFE复合绝缘电线电缆、供电系统优选PFA绝缘挤出型电线、总线系统和高频信号传输选用FC光纤总线及发泡PTFE绝缘同轴电缆。该方案的最大优点在于将航空电线电缆的电性能、减重要求及耐海洋环境的特殊要求做到最大限度的结合,同时,对国内航空电线电缆的研发、制造技术水平亦具有深远的影响意义。

Compare with the land-based aircraft,requirements for the selection of wire and cable in shipboard aircraft is new.On the basis of the ocean environment technical requirements and the maximize probability for weight reduction of the shipboard aircraft,combined with the domestic and overseas development of wire and cable,a reasonable technical project is proposed,i.e.ETFE irradiation cross-linking insulated wire and cable are selected in the room temperature and PI/PTFE smooth tape-wrap insulated wire and cable are selected in high temperature.PFA insulated wire is recommended in electrical system.FC and PTFE insulated coaxial cable can be used in the bus system and the high frequency signal transmission.The main advantage of this project is that the properties and the ocean circulation requirements of the wire and cable are combined as furthest as possible.Meanwhile,it will be of a meaningful significance on the development of the domestic aviation wire and cable.
