介绍了氦质谱检漏的原理,基于氦质谱检漏技术,提出面向机翼整体油箱的检漏方案,包括粗漏检测方法和细漏检测方法,在此基础上,开展氦气-航空煤油泄漏对比试验,确定了能够应用于生产的初步标准。
The principle of helium mass spectrometry leak detection is introduced. Based on the helium mass spectrometry leak detection technology, the leak detection scheme for the whole wing of the airfoil is proposed, including the coarse leak detection method and the fine leak detection method. On this basis, the helium-aviation kerosene leak Contrast tests, to determine the initial standards that can be applied to the production.
