总师曝运-20关键性能参数 证实尚无“超级大运”

2014-03-03 15:20:08   中国新闻网

全国政协委员、运-20重型运输机总设计师唐长红3日在北京接受中新社记者采访时透露,运-20目前仍在试飞过程中,试飞频次和时间均创造了试飞历史上的纪录。

虽然“不能透露”运-20的服役时间,但唐长红表示,民众对大运的期望很高,希望它越早服役越好,但飞机试验一定要到万无一失、非常精准的情况下才可投入使用,目前试验进展非常顺利。他透露,目前正在培训大型运输机的试飞员。

唐长红介绍说,从目前试飞情况来看,达到了预期目的,一些极限要求都达到了原来的设计意图,比如飞行高度、飞行速度等,特别是飞机有比较良好的抗颠簸特性,比较舒服。

运-20重型运输机是中国自主研发的新一代重型军用运输机,由中航工业西安飞机工业集团研发,最大起飞重量估计为220吨,最高载重66吨,能跻身全球十大运力最强运输机之列。2007年3月,中国宣布启动大飞机工程。2013年1月26日14时,运-20在中国阎良基地首次升空,历时1小时。中国大运的成功首飞,标志着中国拥有了属于自己大型运输机。

有外媒估测,中国对运-20的需求量超300架,同时中国也会开放给国外购买。对此,唐长红表示,俄罗斯的伊尔76飞机生产了800多架,美国的大飞机数量也非常多。但每个国家国情不同,中国的航空运输不管民用还是军用都刚刚起步,尚未构建起自己完善的运输体系,与发达国家相距甚远,“因此我相信只要努力做好,未来空间会很大。我们也期望未来能和其他国家有一些合作。”

对于外界“运-20之后中国还将研制超级大型运输机”的猜测,唐长红表示目前中国还没有该计划。他指出,从设计角度来说,大型运输机的诞生不止代表一个型号,更重要的是一批基础的技术、设计能力和生产能力的积累,实际上是一种工业水平的提升,将为国家作出更多贡献。

运-20的兄弟系列何时推出?对此,唐长红表示,“现在的主要工作依然是就运-20的基本稳定性在试飞,还谈不上兄弟系列。中国大型运输机的规划有一些还在酝酿之中,但不能透露。”

唐长红表示,运-20最大载重量66吨,最大起飞重量220吨,负载量非常大。他援引美国的大飞机用途举例说,美国的大型运输机对国家建设起到非常重要的作用。因此中国运-20的定位除军用外,更大的用途将在民用上,比如对建设物资和装备的运输、抗震救灾、民用应急等都将起到重大作用。

运-20性能很高,能适应较为艰苦的条件,在比较粗糙的机场如山区的小机场便可以降落。在设计中对于高寒、高热、高原等恶劣天气情况以及跑道情况都给予了充分考虑。”他说。

唐长红是陕西西安人,于1982年毕业于西北工业大学空气动力学专业,先后参加了“飞豹”飞机、运七-200A、MPC-75、AE-100等型号飞机的研制和重大预研课题研究。现为中国航空工业第一集团公司第一飞机设计研究院总设计师,中国工程院院士。(万淑艳)
