运20获重大进展:已现身华中某市转场试飞(图)

网友拍摄的运-20最新图片。

大型飞机的研制、试飞和生产,是一个国家综合航空实力的标志,更是一个国家国力的体现。而大型运输机由于其自身所具有的特点,使得它的飞行试验在组织管理和实施技术方面有别于常规的中小型飞机。

近日,多名网友目击了运-20已经在华中某城市进行试飞的场景,并拍摄了试飞照片,这说明运-20已经结束在试飞院的前期试飞任务,进入转场试飞阶段。根据运-20的试飞进度推测,试飞院的前期试飞任务主要工作是对飞机进行基本包线扩展试飞、基本性能品质试飞,以及基本测试量试飞,保持飞机的基本技术状态不再发生变化。而此次运-20进入的转场试飞阶段,一般包括以下任务目标:一是考验飞机的极限航程、载重,二是考验雷达、导航、自动驾驶、除冰系统、环控系统在陌生空域、复杂气象条件下的可靠性,三是考验飞机在各种极端环境下的性能,例如海上、寒区、高温高湿地区、高原地区的适应能力,以及各种跑道道面的起降特性。随着转场试飞任务的开展,运-20必将飞赴更多不同区域的城市(比如高原地区)进行各种条件下的飞行测试。

今年8月初,运-20第三架原型机“783”号首次亮相,意味着该机已经投入科研试飞,作为现代军事快速反应、远程机动能力的关键手段的大型军用运输机,还要进行重装空投、空中开关货舱门等等试飞科目。(文:田晨 李小健,图:徐晓岳longplayer)

运-20大型运输机,是中国自主研发的新一代重型军用运输机,代号“鲲鹏”,由中航工业西安飞机工业集团研发,2013年首飞。最大起飞重量估计为220吨,载重量约为60吨。拥有高延伸性、高可靠性和安全性。该机总设计师、中航工业一飞总设计师唐长红院士介绍,220吨级意味着运-20是国内研制的最大的飞机,“标志着中国跻身世界大飞机行列”。

八一建军节来临之际,网络上数张运-20最新试飞照曝光。这架刷涂试飞院“783”编号的运-20大型军用运输机在完成试飞后稳稳降落,背景是西下的夕阳,美不胜收。

主要用途

运-20是由我国自主研发的新一代重型军用运输机空中平台。

作为战斗机的加油机。

搭载大型预警雷达、超级计算机,可改成大型预警机,有比空警2000更大的续航时间。

投放无人机,伞兵。

补给空投物资。

  试飞进程

2013年1月26日下午14时整,运-20在阎良基地首次升空,并于15:00成功降落,至此,中国运-20首飞圆满成功。运-20的成功首飞,标志着中国航空工业的一次重大胜利,标志着中国拥有了属于自己大型运输机,是中国空军建设战略空军的一座里程碑。

首次试飞

此次首飞从下午14时起飞,共历时一小时,期间在试飞现场上空盘旋,14时50分左右在观礼台前低空通场。本次试飞全程由一架歼-15陪同拍摄。

运20代号“鲲鹏”,由中国中航工业西飞集团主要研制,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。

再次试飞

继2013年01月26日运20首飞不到90天后,国产运-20大型运输机于2013年4月20日15:15在西部某试验基地进行了第二次试飞。运-20的第二次成功试飞表明其各项关键技术更趋成熟。

三次试飞

2013年9月,网络上再次出现了首架国产大型军用运输机运-20的最新试飞照片。从照片中,能看到运-20的机头部分刷涂了新的机头编号“781”,数字呈现大红色。

四次试飞

2014年建军节前夕,运20第三架原型机着灰色涂装,编号“783”,在完成试飞后稳稳降落。意味着该机已经投入科研试飞,这将加快运20的研制速度。
