中国国产大飞机C919计划今日首飞

2017-05-05 11:03:41   国际在线

国际在线报道(记者 李晋):中国国产大型客机C919计划于今天(5日)下午在上海浦东国际机场实现“首飞”。

按照计划,C919首飞全程约90分钟,将经历包括地面检查、爬升、平飞、模拟进近、着陆复飞和最后着陆五个阶段。按照惯例,为确保安全,首飞时C919全程不收起落架,同时另一架飞机对首次飞向蓝天的C919进行全程伴飞。

拥有168个座位的C919是中国完全按照国际主流适航标准和国际主流市场运营标准研制的干线飞机。与国际同级别主流客机相比,C919在诸多领域占据了同级别领先地位。C 919型号副总设计师周贵荣介绍说,被称为飞机大脑和神经系统的航电系统就是其中之一:“同等级别的干线飞机里,C919的航电系统是最强的,因为我们研发比较新,采用最新的架构,集成模块化航电系统,带来的好处是,以往系统是独立的,现在很多系统要改变的时候只要软件升级就可以,可以保证飞机不落后,升级快,成本还比较低。”

周贵荣介绍说,C919集成了很多目前业界最先进的功能,比如安装了新的传感器,可以在雾霾等低能见度气象条件中安全起降;采用空地无线宽带技术,乘客可以在空中通过网络与地面联通等等。周贵荣说:“目前航电系统可以做到50%以上由国内或者合资企业在本土生产研制,同时,国产化的研制无论国内还是国外,都是按照同一套国际标准和方法进行要求,供应商的选择,研发过程,实验验证都严格进行考虑,安全方面是有保证的。”

C919是中国自主研制的第一架大型喷气式客机。该机信息化总师潘凌云表示 ,从ARJ支线客机到现在的C919,中国民机制造得以大量应用先进的生产构架和最新的技术、设备,尤其在数字化制造领域的进展速度令人惊叹。潘凌云说:“到C919更进了一步,不仅仅无纸化,而且采用三维化,到现场工人操作的时候,对着我们系统去看,怎么装配,而不是像传统带一张图纸,最大好处是精确、效率高,对我们控制研制成本很大好处。”

据介绍,完成首飞之后,C919的研制工作将开始进入新的阶段。未来C919将一共建造6架试飞机,分别承担不同的测试任务以加快研制进度。在中国商飞返聘总工程师蒋艰看来,C919首飞腾空只能算是“在万里长征中又向前迈了一步”:“研制性试飞的首飞,是研制的一部分,考验我们设备参数性能功能是不是能达到,肯定会发生大大小小优化的要求,我们去准备它完成它,这是最最开始试飞,研制还远远没有结束。”

按照C919大型客机的研制规划,后续试飞中,C919将进入适航审定试飞阶段,通过验证飞机性能获得适航证,最终进入市场运营。目前,C919大型客机拥有中国国际航空公司等23家国内外客户,订单总数570架,其中包括美国通用电气租赁、德国普仁航空、泰国都市航空等国际客户。C919副总设计师傅国华表示,首飞之后,C919未来市场空间将更加乐观:“国内最起码有2000架左右的市场空间,一大部分替换过去老飞机的空缺,另外中国发展也非常快,对新飞机有很大的需求,未来将伴随中国经济的发展,尤其中囯的物流产业的发展,2000架我认为是国内保底的一个需求量。”
