In mid-February, a Japanese drone hit a crane during the automatic return process and injured a worker during the fall, which almost caused the worker to be disfigured. Swiss technology company MeteomaTIcs has invented a drone failure insurance technology that provides a new alternative to known safety systems such as parachutes.
The picture shows the schematic of the patent work.
Compared to the traditional scheme of installing a parachute on the aircraft to ensure safety, MeteomaTIcs intends to install at least one pair of passive lifting axle arms symmetrically on the drone. When the drone is out of control, the axle arm will follow the drone. The aerodynamic axis rotates to provide "passive lift" in the manner of the drone's body rotation, thereby counteracting the fall speed and keeping the drone in a stable state in the air. At present, six-axis or eight-axis UAVs have design power redundancy, but most of the consumer UAVs use a four-axis structure. Once one of the rotors or the engine fails, the drone cannot fly.

It is reported that MeteromaTIcs is a supplier of meteorological products and services. The person in charge of the company said that the technology will be used in the Meteodrone UAV. The Meteodrone UAV is mainly used to collect temperature data such as temperature, humidity and wind speed in the boundary layer of less than 2 km. The drone has a certain risk of "explosive machine". If this technology is introduced to Meteodrone, even if there is any failure during the flight, the aircraft will have a chance to recover completely, and the cost can be saved.
