某型飞机整体油箱密封修理工艺研究

Study on Sealing Repair Process of an Aircraft Integral Tank

飞机整体油箱的渗漏及密封修理是飞机生产、维护、使用中经常遇到的难题。基于某军用飞机机身整体油箱的渗漏修理,就渗漏的原因、漏源的确定、修补工艺及修补材料进行了深入的研究。通过工艺试验,验证了整体油箱异种胶压力灌封二次粘接喷涂覆盖的综合修补工艺的可行性,为今后完善公司军机油箱修理规范积累了经验素材,同时也可为相关研究提供参考。

The difficulties in leakage and sealing repair during the production, maintenance and use of aircraft integral tank have been encountered. Based on the analysis of the leakage repairing process for integral tank of a military aircraft, this paper discusses the cause, source detection and repairing material of leakage. Secondary bonding with dissimilar perfusion sealing under pressure and coverage by spray painting for integral tank repairing is proved to be feasible through test, which provides experience for improving the specification of integral tank repairing in Guizhou Aviation Aircraft Corporation Limited and also gives a reference for other corporations or factories.
