摘　　要：针对某型教练机机身整体油箱内部的钢制铆钉腐蚀问题,考虑油箱装配到使用的过程,结合腐蚀样品的理化测试结果,对油箱内钢制铆钉腐蚀的原因进行了分析,认为腐蚀的主要诱因为油箱内残余的水分。对比同系列其他架次飞机的钢制铆钉锈蚀情况,对此类问题排故与改进提出了建议。Concerning the issue of corrosion of the steel rivets inside the fuselage integral fuel tank of XXX Training Aircraft,taken into account of the process from assembly to use of the fuel tank,in combination of physic-chemical test results for the corroded samples,the cause of corrosion of the steel rivets inside the fuselage integral fuel tank is analyzed.The main induced reason for corrosion is the residual water contents in the fuel tank.By contrast with rust of the steel rivets with other aircraft of the same series,a proposal is raised for troubleshooting and improvement of this kind of problem.
