C919首飞成功,你最想知道的十个问题都在这

2017-05-05 18:52:50   新华网

5日,我国具有完全自主知识产权、首款按照最新国际适航标准研制的干线民用飞机C919首飞成功。

C919已获得来自全球的570架订单。这架大飞机带动了国内飞机制造产业链的发展,实现了中国航空工业的重大历史突破。

关于C919,你最想知道的十个问题都在这里:

1、为什么说C919拥有我国自主知识产权?

C919的全称是“COMAC919”,COMAC是C919的主制造商中国商飞公司的英文名称简写,“C”既是“COMAC”的第一个字母,也是中国的英文名称“CHINA”的第一个字母,体现了大型客机是国家的意志、人民的期望。第一个9寓意“天长地久”,19寓意C919大型客机最大载客量190人。

对于大飞机这样复杂的产品来说,整体的设计是极其重要的。没有整体设计,即使把全世界最好的发动机、机身、飞控、电传等等组合起来,也得不到一架能飞的飞机。C919总设计师吴光辉说,C919是我国自主设计的干线飞机,就飞机整体设计而言拥有完全自主知识产权。

机头、机身、机尾、机翼等外面的“壳子”来自中国的成飞、洪都、沈飞、西飞等企业,而其他许多关键部分都来自外国企业。据悉,全球采购是民机制造的一大特点,波音、空客的供应商也来自于全球。但C919的一个重大使命,就是带动国内民机产业链的发展,相信会有越来越多的零部件来自于中国企业。

2、C919为何不装配国产发动机?

目前,我国还不具备生产适合民用大型客机发动机的能力,而国际民用飞机制造商的发动机也是采购自供应商。

目前,国际上民用航空发动机制造商主要有英国的罗·罗、美国的通用和普拉特·惠特尼、法国的斯奈克玛,以及多国合作的IAE和CFMI。

当然,能用中国的发动机当然最好,但先有大飞机,才能带动民航发动机产业的发展。没有大飞机就没有需求,就不会有平台,这是产业龙头和产业链的关系。

3、C919安全性如何?

吴光辉说,C919大型客机按照更加先进的技术标准设计,采用世界一流供应商提供的最先进的动力、航电、飞控等系统,完全按照国际适航标准设计生产,安全性有充分保障。

最终,C919飞机是否安全不是其制造商中国商飞公司自己说了算,而是要通过中国民航局的适航认证。也就是说,要符合中国民航局关于飞机的各方面测试才能够执行民航的飞行任务,而关于安全性的测试是重中之重。
