Florida-based Undefined Technologies has unveiled the next generation of its "silent" commercial
In the frames below you can see the new prototype inair. However, the video is edited, so it is impossible to check the exact duration of the flight. At the same time, it cannot be called 100% silent. However, Undefined Technologies says it will be quiet compared to current propeller-driven drones.
The design of the model is very different from previous prototypes.
The previous prototype flew for about 25 seconds andproduced a noise of about 90 decibels. Representatives from Undefined Technologies claim that the new Ventus drone flyed for about two and a half minutes, and the noise level dropped to 85 decibels. The end goal is about 70 decibels, or about the same as the DJI Mavic. But they want to implement the idea in a larger glider with some carrying capacity.
Silent Ventus is a prime example of our intention to create a sustainable, progressive and less noisy urban environment.
Thomas Prybanik, Founder and CEO of Undefined Technologies
It is unclear how the company plans to continuereduce noise levels on a device whose powertrain no longer has moving parts. The company is also not making any promises about range or endurance at this stage. The Ventus drone itself ionizes the air to create lift without moving engines.
