韩军方“解剖”朝鲜无人机:用7国零件 续航能力强

2017-06-23 00:45:03   参考消息

调查显示,无人机航迹从金刚郡直达庆尚北道星州,这与无人机摄像头存储卡里的555张图片显示的航迹一致。由此推测,无人机主要任务是侦察“萨德”基地。

报道称,存储卡里的555张照片中有四张被推测为在起飞前试拍的照片。其余551张是在无人机飞行中拍摄的,其中有关“萨德”基地的照片有10余张,但分辨率不高,只能模糊辨认“萨德”发射车等重要装备。

报道称,无人机5月2日上午10时起飞,同一天下午1时9分许拍摄了“萨德”基地。无人机重量13公斤,全长1.85米,翼展2.86米,略大于白翎岛无人机。

另据韩国《朝鲜日报》6月22日报道称,朝鲜最近为了侦察庆尚北道星州的驻韩美军“萨德”基地而派出的无人机,至少用七个国家的配件制造而成,将续航距离增加到此前无人机的两倍,对性能进行了大幅提升。该无人机本月8日在江原道麟蹄的山区被发现。韩国国防部发言人文尚均21日在发布会上说:“飞行路线的分析结果显示,起飞地点和计划回归地点都属于朝鲜地区。”

朝鲜为了增加续航距离,安装了大功率引擎。此外,为了多装载燃料,还减轻了其他装备的重量。麟蹄无人机的燃料箱容量为7.47L,超过白翎岛无人机(3.4L)的两倍,照相机的重量从大约900g(日本尼康D800)压缩到大约400g(日本索尼α7R)。

报道称,朝鲜至少在无人机上使用了七个国家的配件。引擎是捷克制造的,飞机控制电脑是加拿大公司(Micro Pilot)的。此外,GPS信号接收器是瑞士(Ublox)的,GPS天线是美国(Trimble)的,RC信号接收器和照相机是日本的,电池是中国的产品。控制机翼动作的伺服电机是韩国Hitec RCD的产品。

报道称,对相当于无人机大脑的飞行控制电脑中存储的飞机记录和事先输入的飞行计划进行分析的结果显示,该无人机上月2日上午10点从朝鲜江原道金刚郡起飞,飞越军事分界线(MDL)上空,在庆尚北道星州“萨德”基地上空盘旋后,在回归起飞地点的过程中,于下午3点33分在麟蹄郡山区坠落。此时离起飞时间已过去5小时33分。经调查,该无人机巡航速度为时速90公里,飞行高度为2.4公里,总飞行距离为490多公里。
