现代飞机是一个极为复杂的高技术工程系统，研制一种新飞机需耗费巨额资金。当今世界各国均因财政问题而很少独自研制一种大型新飞机的；几个国家联合研制新飞机的做法，已成为当今世界航空工业的一个必然趋势。欧洲是合作研制飞机最多的地区，其原因：一是解决经费问题，二是 Modern aircraft is an extremely complex high-tech engineering system. The development of a new aircraft requires a huge amount of money. All countries in the world today rarely develop a large-scale new aircraft independently because of financial problems; the joint development of new aircraft by several countries has become an inevitable trend in today’s world aviation industry.
