In case of losing control of a drone, certain emergency systems are necessary to avoid the destruction of the drone and furthermore to minimize the danger for objects and human beings on the ground. Just recently, Meteomatics received a new US- patent from the United States Patent and Trademark office for an innovative alternative to known safety systems such as parachutes.
At least two passive lift elements are arranged radial-symmetrically about a yaw axis of the drone. In the event of an uncontrolled fall, these twisted passive lift elements initiate a rotation about the yaw. Thereby, the position of the drone will be stabilized in space.
Furthermore, the rotation generates a dynamic lift which reduces the fall and crash velocity of the drone.
Martin Fengler, Meteomatics CEO, says: "The multiple utilization of a component part, for example the passive lift elements, offers the advantage of saving weight, which is essential for our operational service with the Meteodrones. Additionally, this new system will further reduce maintenance costs."
The Meteodrone was developed to close data gaps in existing weather models. These gaps concern the boundary layer, which is the main trigger of phenomena like fog, low stratus, freezing rain and thunderstorms. The Meteodrone enables highly accurate measurements of weather parameters in the boundary layer.
