Drone Startup Claims It Flew Its Ion-Propulsion Drone On 4.5-Minute Test Flight

An anonymous reader quotes a report from Interesting Engineering: Florida-based tech startup Undefined Technologies announced its unique ionic propulsion drone has passed an outdoor flight test, meaning it's on track for commercial release in 2024, according to a report from New Atlas. The drone, called Silent Ventus, uses proprietary technology to ionize the oxygen and nitrogen molecules in the surrounding air to create an "ionic wind" that propels the machine in the direction it wants to go. According to Undefined, the drone could be used for cargo. Though it's not been used for large-scale drone projects on Earth before, ionic propulsion isn't a new technology. In fact, it's currently one of the best technologies humans currently possess for deep space exploration propulsion and other space applications. According to Undefined, its "Air Tantrum" ionic propulsion technology produces up to 150 percent more thrust than current ion thruster technologies. Earlier this year, the company released footage of a two-and-a-half-minute indoor flight test, saying the drone emitted 85 decibels of noise. Now, it claims it's flown a prototype for four and a half minutes, though it's only released one minute, 17 seconds of footage. The drone firm also says it achieved a noise level below 75 dB. It's now aiming to secure further investment to build a zero-emissions cargo delivery drone by 2023 that could fly for 15 minutes and make less than 70 dB. Undefined claims its "silent" 70-dB drones will lead to far fewer noise complaints in areas that will be served by urban cargo delivery drones in the future. However, it's worth pointing out that Undefined had yet to test its drone with large payloads, which will require extra thrust and will likely make more noise.Read more of this story at Slashdot.
