Firefighters have a tough job, particularly because of the whole “entering a burning building” part. Wouldn’t it be great if they could direct water to put out fires in the interior of a building without having to actually go inside themselves? That’s exactly what DragonFireFighter is designed for, and it looks very promising.
DragonFireFighter — which was created by researchers at Tohoku University and the Hachinohe Institute of Technology — works by flying on high-pressure water jets. At first glance, it looks like a standard firefighting hose with two boxes placed around the hose at the end. Those boxes contain controllable nozzles, which allow the firefighters operating DragonFireFighter to direct the hose where it’s needed.
In the video, they test DragonFireFighter by flying it through a window in a mock-up wall to extinguish a fire in a barrel on the other side. That simulates a fire in the interior of a building, and demonstrates the potential for putting out fires remotely. The DragonFireFighter prototype is fairly short, so it can’t move too far into a building as it is. But, it would be simple enough to extend the reach by making the hose longer. If firefighters had this at their disposal, it could almost certainly save lives.
