A new drone with two propellers and with what is defined as an “advanced stabilization system” was developed by a group of engineers from Flybotix, a start-up of the Ecole Polytechnique Federale de Lausanne (EPFL).
According to the EPFL press release, this drone can boast better autonomy as it can fly twice as long as classic models. It is also smaller in size, always compared to the average, and this means that it can also be used in those cases where it is necessary to inspect cavities or areas that are difficult to reach, such as those in industrial plants.
This new drone would, therefore, resolve what is considered the main defect of today’s drones, or the low battery autonomy. The drone created by Samir Bouabdallah and colleagues, can count on a new propulsion system that mimics that of helicopters. Thanks to this system it can only use two propellers and this already reduces battery consumption.
The engineers then added a special stabilization based on algorithms that provide better aerodynamic performance, once again similar to those of a helicopter.
The new stabilization system is necessary: a drone with only two propellers is less stable and more difficult to manipulate than a quadcopter, ie a drone with four propellers. The stabilization was obtained through a particular ring structure with the propellers which, stacked one above the other in the center, turn in a different direction.
