乌克兰无人机救援受伤士兵，将伤员撤离概念投入实战
Ukraine’s drone rescue of wounded soldier puts much touted idea into practice
乌克兰第92突击旅用 Gurzuf Defence 免费提供的重型六旋翼无人机 Heavy Shot AYUDAG 6 完成首次战场伤员空中撤离，士兵借助绞盘和安全扣被吊运后送。飞行全程 1 小时 14 分钟，距离近 39 英里（62 公里），该机可载重 200 磅（90 公斤）。因俄军无人机和地雷威胁，轮式地面机器人无法进入该前线区域，伤员已在阵地坚守近 500 天。
Ukraine’s unprecedented drone rescue of a wounded soldier from the battlefield has shown once again how battlefield necessity can spur innovation. The operation was revealed just days after separate Ukrainian drones designed for casualty evacuation were deployed for frontline testing—taking a step beyond the US military’s decades of experimentation with similar concepts.
The drone evacuation of the injured soldier took place at an undisclosed time and place on the frontline where the presence of Russian drones and landmines made it impractical to send in a wheeled ground robot, according to The Kyiv Independent. On October 19, Ukraine’s Army shared a video of the drone evacuation, showing the wounded soldier securing himself in a harness suspended beneath a heavy hexacopter drone with six rotors before being flown to safety.
“This is a historic event, the next stage of evacuating the wounded, which we will all come to,” said Napalm, a programmer of the 92nd separate assault brigade’s unmanned ground systems company, who went by his callsign per Ukrainian military practice, in a statement. “Now the serious systematic work begins, so that such missions are carried out constantly.”
Flying out the wounded
To perform the improvised aerial evacuation, the 92nd brigade prepared and tested a heavy hexacopter drone—the Heavy Shot AYUDAG 6 model—provided for free by the Ukrainian manufacturer Gurzuf Defence. Special carabiners were first delivered to the wounded soldier so he could attach himself to the drone that was equipped with a winch, according to a blog post by Gurzuf Defence.
The wounded soldier, who serves with Ukraine’s 30th separate mechanized brigade, had already spent nearly 500 days at a frontline position while under threat of Russian fire, according to Gurzuf Defence. Like many soldiers at frontline positions, he had been relying on friendly drone deliveries for ammunition and other supplies.
The drone evacuation flight took 1 hour and 14 minutes from start to finish while covering a distance of nearly 39 miles (62 kilometers). This particular hexacopter can reportedly carry up to 200 pounds (90 kilograms).
