飞机结构强度试验中的油箱泄漏检测

The Leak Detection for Fuel Tank in the Aircraft Structure Strength Test

通过介绍飞机油箱的结构特点,总结出燃油泄漏原因及泄漏高发区域,并对现有的内外漏点检测方法在强度试验环境下实施的可行性进行分析,最后基于超声泄漏检测和氦质谱检漏技术,结合试验验证结果和外场应用成果,制定出适合强度试验中油箱泄漏检修工作的实施方案.

This paper introduces the structural characteristics of the aircraft fuel tanks, summarizes the causes and high-incidence areas of fuel leakage, and analyzes the feasibility of the existing internal and external leakage detection methods under the strength test environment. Finally, the implementation plan of the oil tank leakage repair work in strength test is formulated based on the ultrasonic and helium leak detection technology and on the combination of the results of test verification and field application.
