氦质谱检漏在某型机翼装配中的应用

Application of Helium Leak Detection in a Certain Type of Wing Assembly

采用氦质谱检漏技术对某型机翼整体油箱检漏方法进行工程化应用研究,提前并准确定位漏源、精准排除故障,避免因传统气油密试验工序滞后带来的问题,降低返工及时间周期成本,具有明显的效益。该研究成果可推广应用于飞机其他密封部件装配检测,同时也对数字化检测技术在飞机密封装配中的应用进行了有益探索。

By researching engineering application of helium leakage detection technology on a certain type wing integral fuel tank leak detection to locate the leaking resource accurately and in advance, to remove the trouble preciously, to avoid the hysteresis of problem finding caused by the delay of traditional airtight and oil tightness test procedure, and to reduce rework and time cost, which has obvious benefits~ The research result can be generated and applied in other sealing components assembly test, and it is a beneficial exploration on application of digital detection technology in aircraft sealing assembly as well.
