| 目的 针对某型飞机的腐蚀问题开展研究,制定结构腐蚀修理和防腐改进措施。 方法对外场飞机的腐蚀情况进行统计归类,对现有飞机防护体系进行梳理,分析结构腐蚀原因和防护体系的不足。 在对飞机服役地区环境进行实测的基础上,编制飞机地面停放环境谱和飞机结构局部环境谱。 研究制定结构防护体系设计改进措施,并通过加速腐蚀试验验证设计改进效果。 结果与结构设计改进前的原始状态相比,防腐改进后的结构日历寿命提高 1. 6 ~5 倍。 结论 飞机防护体系薄弱的情况下容易引发多种类型的腐蚀问题;系统地对飞机结构腐蚀问题进行治理,才能取得令人满意的效果。 |

| Objective To study the corrosion problem of a certain aircraft, and to formulate structure corrosion repairing and anti-corrosion measures. Methods The corrosion reasons and the defects of the structure protection system were obtained after statistical analysis of aircraft corrosion classification and combing of the existing aircraft protection system. On the basis of aircraft serving area environment measurement, the aircraft ground parking environmental spectrum and the local environmental spectrum were developed. The design improvement measures for the structure protection system were taken, and the improvement effect of the design was verified by the accelerated corrosion test. Results Compared to the original state before improvement of the structure design, the calendar life of the anti-corrosion improvement structure was extend by 1. 6 to 5 times. Conclusion The aircraft was easy to subject to a variety of types of corrosion problems under the weak protection system. Good effect could only be achieved through systematic treatment of the problems in aircraft structure corrosion. |
