摘要
介绍了铝材在完全拥有自主知识产权的国产大飞机(ARJ21-700与C919客机)上的应用状况,评述了C919客机上首次应用的铝-锂合金的种类、来源及其应用效果。分析了中国航空航天用铝材生产所面临的问题并提出了建议。
This article stated the application of aluminum materials on domestic large air- crafts with independent intellectual property rights (ARJ21-700 and C919 airliners). It also described the varieties, sources and application effects of Al-Li alloys, which were applied to the C919 airliner for the first time. Meanwhile,it analyzed the problems existing in the aero- space-used aluminum materials and proposed corresponding measures.
