The Ventus drone uses ion propulsion

The Ventus drone is powered by ion propulsion rather than a propeller, and each successive version is becoming quieter.

Ionic propulsion has already proven useful for spacecraft propulsion, but the situation on Earth is different because flight takes far more effort and energy.

Undefined Technologies says it is well on its approach to building a commercial ion-powered drone that will be more energy efficient in Earth's gravitational circumstances.

In June, the business plans to unveil Ventus Silent, a new design for its Ventus drone. He employs Air Tantrum technology, the specifics of which are not yet known.

As you can see in the video below, the initial generation of their drones couldn't remain in the air for long and created a lot of noise.

The new ion-powered Ventus Silent prototype will be substantially quieter, producing no more than 70 decibels of noise, which they claim is already similar to drones with propellers.

The original version made 90 decibels of noise and barely flew for 25 seconds. This required the business to create something new in order for the drone to be considerably quieter and utilize less propulsion energy. So far, they've said nothing about how they plan to accomplish this with a device that already has no moving parts.

The company has also not disclosed any information on the ionic drone's range or the heights to which it would be able to fly.

DRONE RACE:

You have the opportunity to see one of the impressive engineering achievements, which surprises us more and more often in the modern age.

With the exception of military industry circles (who knows what is being cooked there), forcing a group of drones to coordinate perfectly, avoid obstacles, and detect targets without colliding with each other, is not a seemingly easy task.

Experiments of this type are mostly performed in strictly controlled environments and with a clearly defined path created by algorithms and under the supervision of experts for this type of robotics.

Students from the University of Zhejiang Province of China went a step further, as soon as we are here and after such an introduction, right ?!

They have developed an algorithm that allows a swarm of 10 palm-sized drones to rush through the bamboo forest completely independently, correcting its movement in front of obstacles in just a few milliseconds. 

Navigation does not rely on the GPS system, so they are suitable for use in areas where the signal is weak. In addition to navigating in nature, the code was also tested to track one person.

Four drones, from four different angles, managed to keep the target on the radar even if it briefly slipped out of sight.

Such a system could in the future assist in natural disasters when it is necessary to observe potentially dangerous terrain from a safe distance and locate the endangered. More drones will certainly do it faster than one. 

We will not talk about possible abuses, which some experts warned about after watching this video, because everything that is good can always be abused in some way, but we hope that it will not be like that…
