参考消息网6月23日报道 韩媒称,韩国国防科学研究所相关负责人21日表示,调查显示6月初在江原道麟蹄郡发现的小型无人机外观类似于2014年在白翎岛坠落的无人机,航程则翻一番。
据韩联社6月21日报道,在白翎岛坠落的无人机续航距离达180-300公里,而在麟蹄郡坠落的无人机已经完成的飞行距离就达490公里,这说明发动机性能得到提升。白翎岛无人机的发动机功率仅为35cc,麟蹄无人机配置捷克产50cc二冲程二汽缸引擎,安装在无人机上的电池容量也是白翎岛无人机的两倍。
分析指出,虽然麟蹄无人机的引擎性能较白翎岛无人机明显改善,但其坠落的原因却在于引擎缺陷。韩国国防科学研究所分析认为,由于引擎失常,飞行速度变得缓慢,油耗量过大,最终无人机坠落。
报道称,分析无人机配备的飞控计算机显示,起点和预定终点——朝鲜金刚郡周边八处和飞行航迹上的18处被设定为航路点。
