Interestingengineering.com reported that in April, Florida-based Undefined Applied sciences unveiled its silent (or at the very least comparatively quiet) eVTOL drone, Silent Ventus. The drone is powered by ion propulsion. “Silent Ventus is a vivid instance of our intent of making a sustainable, progressive, and less-noisy city surroundings,” stated Tomas Pribanic, Founder and CEO of Undefined Applied sciences, within the assertion. “The design brings us nearer to our ultimate product and permits us to showcase the dual-use of our know-how.” In line with Undefined Applied sciences’ web site, the drone as we speak “makes use of modern physics ideas to generate noise ranges under 70 dB.” This may make it ideally suited to be used all through the U.S., the place acceptable noise ranges for residential, industrial, and business zones vary from 50 to 70 dB.
“Ionic wind,” often known as electroaerodynamic thrust, is a bodily precept that was first recognized within the Twenties and describes a wind, or thrust, that may be produced when a present is handed between a skinny and a thick electrode. If sufficient voltage is utilized, the air inbetween the electrodes produces ample thrust to propel a small plane. Watch a background video on ION propulsion right here.
