The growth of drone technology has been large in recent years, as several of the components and systems have evolved to make them each time faster and even undetectable to a GPS.
In the War of Russia and Ukraine thousands of these advanced devices have been seen, while China is also achieving milestones in its models. Although the advance has been very impressive, There is still something to work and it is something very difficult to achieve. It is the noise emitted by the propellers or wings of these devices.
The sound is usually elevated and can be detected at a distance, but stopping the movement so that it is not an option. The famous painter of Mona Lisaalso made great scientific and technical innovations with their knowledge and creativity, reaching Make machine designs and engineering systems that were advanced for their time.
Among the various studies he did on aerodynamics, one of the ancient sketches that allowed them to contain crucial information for the development of drones and could mark a before and after.
Leonardo da Vinci is the key to making drones more silent
In 1480 no human being of today existed, but although the years go by, since then things are maintained that have helped the technology of the world to grow with bright minds like Albert Einstein.
Among one of the geniuses that have left a very marked footprint, is Leonardo Da Vinci, the same one who did the famous works as The Last Supper or the Man of vitruvio. Beyond that, It was an inventor and engineer who managed to make great innovations In his time and created the bases for many of the devices used today.
For example, it came to devise and conceptualize some flying machines, defining goals such as the ornithopter, helicopter and parachute that were subsequently materialized with advances after the years. Now the Universider Johns Hopkins (of.uu.) has discovered something interesting about sketches of this unforgettable inventor.
As Science & Vie explains, thrown from the magazine Bulletin of the American Physical Society, The plane in question is the «aerial viewfinder» And it is crucial for the investigation of improvements for current drones because it could be reduced by the annoying noise that these devices emitted when flying.
«From this project, we build a 3D model of the form of the Da Vinci propeller loop and then use our simulation software, Vicar3D, to simulate the air flow around the rotor while the drone moved in stationary flight. The software predicted the air flow speed around the propellence and the pressure patterns.»
Current models have the ability to fly with power using 4 propellers (quadcoptera), 6 propellers (hexacoptera) or 8 propeller (octocoptera). According to Mechanical Engineering Professor, Rajat Mittal, and the doctoral student in Mechanical Engineering, Suryansh Prakhar, this could change with Da Vinci’s proposal.
Instead of carrying so many wings, with a single sheet that It has a screw shape and a larger surfaceit is possible that the noise pollution of drones decreases significantly. Of course, the reason why it is not usually applied is that it reduces speed, aerodynamic efficiency and would have to use simpler models, but it would work and at a point they could even reach a dream power without so much noise.
With the simulation they did, they could realize that match support and make a silent method exist of staying in the air. It is still something that continues in research and development, but when the time comes, it will surely serve a lot for a new generation of drones.
