解密你不知道的C919:零部件供应商来自全球

2017-05-05 09:28:33   北京晨报

  昨天,商飞官方正式公布了参与此次C919首飞的5名试飞员团队。其中包括1名机长(左三)、1名副驾驶、1名观察员与2名工程师。今天最终执行试飞的人选还可能发生调整,因此在“首发”的五人队伍之外,商飞还准备了一支强大的“替补团队”。

今天,我国自主设计研制、具有国际主流水准的干线客机C919计划在上海浦东国际机场的第4跑道首飞。随着机舱内部照及首飞试飞员陆续公布。C919还有什么秘密,首飞前还要做什么准备?两位航空人将解密你不知道的C919。

  总设计师吴光辉零部件供应商来自全球

昨天上午,C919的总设计师吴光辉还在基地的机库内忙碌着,“首飞是一款新型飞机研制的重要节点,我作为设计师十分激动,但同时我又要不断提醒自己要冷静下来,多想一想,首飞中还会出现什么问题。”吴光辉说。

自主设计,对于一架飞机意味着什么?吴光辉告诉记者,拥有完全自主知识产权是针对飞机整体设计来说的。这主要体现在三个方面:第一,根据市场需求,设定设计方案。“我国已经有了新支线客机ARJ21,原本我想设计更大的飞机,但经过市场调研,150座级的客机是市场上的主流机型,市场前景最好,因此,我们以首先满足国内市场需求为导向选定了这个机型。”

第二,零部件供应需符合设计方案。C919的供应商来自全球,其中不乏同样为空客和波音的供应商,而需要什么样的零部件,对其有怎样的技术要求,这是由中国商飞决定的。“供应商可以来自于全球,但零部件的供应需符合飞机设计的要求,这体现出我们的自主权和决定权。”吴光辉说。

第三,系统集成掌握在自己手中。一架大型客机是复杂的系统集成工程,不同的系统集成在一起需要满足哪些要求,这一控制方案掌握在设计团队手中。“中国商飞的知识产权也体现在对系统之间的集成控制上。C919飞机上有几百万个接口,这关系到液压、航电等多系统之间的关联,绝不是简单的拼接,如何关联,就取决于飞机的设计方案。”吴光辉说。
