飞机导管滑动挤压无扩口连接设计与试验研究

摘要

针对飞机导管损伤原位修理难题，设计出了滑动挤压无扩口连接接头，以及管接头和管套的结构形式，并阐述了接头的连接原理。试验结果表明，设计的滑动挤压无扩口连接接头满足了飞机导管修理技术要求，可用于飞机导管损伤的快速修理。%Sliding extrusion non-flaring connection is designed aimming at normal position repairing problem of aircraft tube,and the structure form of tube union and pipe box is also designed.Joint principle is also expounded.The test results show that the designed joint’s performance can meet the demand of tube damage repair,the joint can be used in rapid repair aircraft tube damage.
