If you own a drone or have a friend who is, even one of these very small ones that they usually sell in shopping centers for children, surely you have tried to make it fly from your hand, by which time you will have noticed. of the enormous turbulence that is capable of generating and the amount of air that moves under it. Imagine now if, instead of being one of these small drones, it is a much more capable model in the style of those that companies such as Parrot, DJI and the like can sell.
One of the recent studies in NASA it has a lot to do with studying these strong wind currents. Specifically, what the engineers of the United States Space Agency have tried is to try to demonstrate how, by knowing much better how these currents are generated, by optimizing them, we could significantly improve the design and characteristics of this technology in future models.
NASA shows us in video what the turbulence generated by a drone like the DJI Phantom 3 looks like.
Far from what may seem to the naked eye or through our sensory field, the air currents that are generated they are incredibly complexYou can see an example of everything that I try to explain to you in the video created by those responsible for this project and that I have left you hanging just above these lines. Thanks to it we can see how the air generated by what NASA assures is a DJI Phantom 3Not only does it move away from the drone's propellers, it also interacts with the leather of the ship in a rather amazing way.
The investigation has been carried out by the NASA Ames Research Center, which in turn confirmed that doubling the number of rotors almost doubles the thrust of the ship, which would increase the weight that it is capable of lifting and transporting and make autonomous vehicles more useful for practical applications.
