摘　　要：C919大飞机、"鲲鹏"运-20四发涡扇重型战略运输机、"鲲龙"AG600大型两栖飞机是中国航空领域的"国之重器",它们都是中国自行研制的,有完全自主知识产权。制造它们所需的铝材到2022年都能全部国内生产,每架C919飞机的铝材采购量约90 t,每架运-20运输机的铝材采购量约110 t,每架AG600飞机的铝材采购量约70 t。在未来的20年内,中国需要与C919等同大小的飞机超过5 100架、运-20运输机120架、AG600飞机不会超过50架。C919 big plane,Xian Y-20(Kunpeng) 4-turbine heavy transport,and AG600 (Kunlong) big amphibian are three most important machines in China's aviation field. All of them are developed by China,enjoy independent intellectual property rights,and the aluminum materials used for them will be totally supplied by local manufacturers before 2022. Around 90 t aluminum materials are purchased for each C919,110 t for Y-20,and 70 t for AG600. In the next two decades,China will need over 5 100 big planes with the size equal to C919,120 transport planes of Y-20,and less than 50 of AG600 big amphibians.
