柔性泄漏检测技术在航空航天工业中的应用

Application of Flexible Leak Test Technology in Aerospace Industry

随着航空航天产品制造密封性要求的不断提高,对泄漏检测技术提出了更高的要求。目前,氦质谱泄漏检测技术在航空航天领域已得到了较广泛应用。航空航天产品待检件结构、大小、要求种类繁多,因而泄漏检测技术的柔性化、通用化成为了其发展方向。通过系统介绍论述不同产品的常用检漏方法的柔性化应用,为从业人员如何根据特定的条件选择合适的检漏方法提供了必要依据。

With the improvement about tightness in aerospace industry. the leak test technology is re- quired with a higher level. The helium mass spectrometer is used widely in aerospace industry. Because the products in aerospace industry are various in structure, size and demand, the flexibility and universalization becomes to be the development direction about the leak test. By means of introducing and discussing the common leak testing methods of different products, the way of choosing appropriate leak testing method is presented here for insiders.
