解密你不知道的C919——访C919总设计师吴光辉
飞机设计研制是一项科技攻坚的大型工程,为此中国商飞公司团队实现了102项关键技术攻关,主要涉及气动技术、新材料、强度设计等方面。
吴光辉说:“C919设计研制中有多项重大技术突破,比如超临界机翼的设计。飞机设计,气动先行,机头、后体的设计也关系到飞机阻力的减小,但机翼的设计决定了飞机的性能,是最为关键的。我们第一次自主设计超临界机翼,就达到了世界先进水平,得到了国际同行的认可。”
此外,新材料的应用是C919的一大亮点。“C919是第一次大范围地采用铝锂合金的机型,我们为此经过了十年的探索,铝锂合金的供应商是按照我们的要求改善了材料的特性,使之能够更好地适用于C919飞机。”吴光辉说。
飞机的性能究竟如何,还有待于在实际的飞行试验中进行检验。首飞完成后,C919将进入适航取证阶段,接受各项飞机适航的测试考验,为敲开市场大门做准备。
吴光辉说:“C919是在一个合适的时间,以一种正确的模式,推出的一款高水准的产品。C919首先是要满足我们国内的航空运输需要,因为中国是全球最大的民航市场,飞机需求最多。立足国内市场,面向全球市场,这是我对C919的定位。从设计航程看,C919可以满足中国任何点到点的飞行。”
吴光辉参与过我国多款主要机型的设计工作,而他认为,C919是最先进的,相信也会是最成功的。“我希望,也期待着,C919能够受到市场的追捧,希望它能够成为一款明星飞机。”
