Ion Propulsion Drone Flight Mission II (Dec 21, 2021)

On 21 December 2021, the Undefined Technologies’ ion propulsion drone successfully completed its next test flight with a significant increase in thrust levels and mission time. During the 2-minute and 30-second mission flight, the team tested the aircraft’s performance, flight dynamics, endurance, and noise levels. The results of this milestone showed the craft’s flight time extended to five-fold from the previous version and generated noise levels below 85 decibels. “The past eight months have been an incredible journey, challenging and rewarding at the same time,“ says Tomas Pribanic, Founder and CEO of the company. “I’m extremely proud of our highly dedicated team who could overcome the technical challenges along the way and advance our ion propulsion technology and manufacturing processes to the next level. With achieving this new milestone, new knowledge, and further understanding of physics, we’re one major step closer to our objective of bringing to market our silent drone.“ Learn more here: Sign up for our newsletters here:
