The latest to do so is Swedish firm ANAVIA, which has created what it calls an “unmanned helicopter” capable of flying for up to 240 minutes with a payload of up to 65 kilos (140 pounds).
Already certified by the Swiss Federal Office of Civil Aviation, the HT-100 VTOL should be ready to fly in just 15 minutes, according to the parent company, and it can operate even in the most extreme weather conditions.
It’s based on a lightweight carbon construction for the cell and the rotor blades and comes with a backup electric drive that kicks in as an emergency system. The parent company says it used a 15 kW shaft turbine specifically to obtain low vibrations, while the gearbox sports a closed design with a low maintenance system.
