With Two Successful Flight Tests And Less Than $2 Million In Seed Money, Florida Company Undefined Technologies Announced Its Next-generation "silent" Commercial UAV It Is Reported That It Uses An Ion Propeller Rather Than A Propeller. The New Design Must Be Visually A Step Higher Than Previous Efforts, But At The End Of The Day, The Ion Propulsion System Will Look Like An Ion Propulsion System.
As Needed, It Will Have A Large Grid Of Electrodes - At Least Two Layers, So That The Top And Bottom Electrodes Can Be Input With High And Opposite Voltages To Accelerate The Ionized Air Down And Generate Thrust. Therefore, Although The Wrapped Cover Is A Good Ornament, It Still Looks Like A Flight Tray Under It.
Although It Turns Out That Ion Propulsion Is Very Useful In Space, Can It Really Effectively Replace The Propeller Close To The Earth? MIT Has Published Research On Its Ion Driven Fixed Wing Aircraft, But For Vertical Lift Aircraft, It Needs More Thrust And More On-board Energy Storage.
For The Company Name Of Undefined Tecnologies, We Have To Choose It Is Quite Suitable. Even After A Year And A Half, People Are Interested In Its Novel Air Tantrum ™ Technology Is Still Poorly Understood And The Company Says It Will Remain Quite Silent. However, Its Flight Video In December 2021 And CEO Tomas Probanic's Speech At The Logistics Conference In January Did Find One Or Two Interesting Episodes.
Probanic Said The Company's Initial Proof Of Concept Flew For About 25 Seconds And Made A Sound Of About 90 Decibels. He Said The New Prototype Had Flown For About Two And A Half Minutes And The Measurement Result Was 85 Decibels. It Is Estimated That They Will Have A Larger Cargo Carrying Capacity Of About 70 DB, But It Is Estimated That They Will Have A Larger Cargo Carrying Capacity. It Is Unclear How The Company Expects To Continue To Reduce The Noise Of A Device That Has No Moving Parts In The Propulsion System. At This Stage, The Company Also Made No Commitment To The Mileage Or Endurance Capability.
In The Following Video, We Can See The New Prototype Flying In The Air, But The Company Has Edited The Lens, So We Can't Verify The Full Length Of The Flight. It Looks More Stable Than The Proof Of Concept, Although It Flies Indoors And Is Not Affected By Any Wind. In Terms Of Noise, There Is An Interesting High Pitched Whistling Sound, And The Way The UAV Bends When Landing Is A Little Worrying, Only Due To The Size And Weight Of Its Structure. It Doesn't Look Bulky, And It's Conceivable That It Would Be Very Difficult To Scale Up These Things Without Making Them Vulnerable.
