The Flying Anemometer: Researchers test hexacopter as wind sensor in world's first 3D wind tunnel
In order to test feasibility of using drones as a flying wind sensors, researchers from the Institute of Robotics and Mechatronics of the German Aerospace Center (DLR) have performed autonomous flight experiments in September 2015 with a custom designed hexacopter in the WindEEE Dome in London, Canada, the world's first 3D wind tunnel. A newly developed algorithm utilizes the drone's propellers to sense the wind speed.
The research is presented in the paper:
