前言飞行器导管连接接头不仅数量众多而且要求能连拆和密封可靠。过去一般均采用螺纹球头作为连接接头。为减轻接头重量和空间,近年来在国外导管总装全位置高频钎焊和徐钎技术得到了发展并成功地满足了密封、操作简便等要求。但是,美苏对本工艺一直实行封锁。 INTRODUCTION Aircraft manifold connectors are not only large in number but also require continuous disassembly and seal reliability. In the past generally use threaded ball head as a connector. In order to reduce the weight and space of joints, in recent years, all-position high-frequency brazing and brazing technology in foreign conduit assemblies have been developed and successfully meet the requirements of sealing and easy operation. However, the United States and the Soviet Union have blocked the process.
