浅析直升机的外场腐蚀防护

目的为加强和改进直升机腐蚀防护工作提供依据。方法通过X1和X2系列直升机的典型腐蚀案例,对直升机腐蚀原因及危害性进行分析。结果由于使用环境恶劣等原因,现役X1和X2系列直升机普遍存在腐蚀问题,已成为严重影响直升机使用维护、经济修理和飞行安全的关键因素。结论从外场防腐改进、腐蚀检测、定期冲洗去除直升机表面腐蚀性污染物、防腐涂层的保护和修复、先进的防腐技术的应用、单机腐蚀监控等方面提出了直升机外场腐蚀防护的措施。

Brief Analysis of Helicopter Field Corrosion Prevention

Objective To provide the basis for strengthening and improving the helicopter corrosion prevention efforts. Methods Corrosion reasons and hazard were analyzed through the X1 and X2 helicopter typical corrosion cases. Results Due to bad operation environments and other reasons, corrosion problems were prevalent among in-service X1 and X2 helicopters. Corrosion has become the key factor which seriously affects the operation, maintenance, economic repair and flight safety of X1 and X2 helicopters. Conclusion Some corrosion prevention measures for helicopter were given, which included: improving field corrosion prevention methods, corrosion detection, flushing corrosive pollutants of helicopter surface regularly, anti-corrosion coating protection and repair, the application of advanced coating technologies, corrosion monitoring technology etc.
