Will the physics add up for near-silent, ion-propelled cargo drones?
Posted by Genevieve Klien in categories: drones, physics
Floridaâs Undefined Technologies claims it has managed to increase the thrust levels of ion propulsion systems to âunprecedented levelsâ with its âAir Tantrumâ technology, enabling near-silent drones with no moving parts, that look like flying pallets.
All aircraft propulsion systems provide thrust by moving air or another propellant, and for the vast majority of drones that means some kind of fan or propeller spinning angled blades to push air through and create thrust in the opposite direction. Ionic propulsion, on the other hand, is entirely electromagnetic.
The process uses a high-voltage electric field to ionize the nitrogen and oxygen molecules in the air, liberating electrons to create, primarily, a lot of positively-charged nitrogen molecules. These are drawn toward a negatively-charged electrode, usually in the form of a flat screen grid, and as they accelerate, they bang into other air molecules and bump them in the same direction to create an ionic wind.

Drones Solve a Nuclear Waste Mystery at Chernobyl
Posted by Quinn Sena in categories: drones, nuclear energy
In 2019, Switzerland-based Flyability had a mystery to solve at the Chernobyl Nuclear Power Plant. Was nuclear waste still present in one of the plantâs decommissioned reactors?
âAt the time of the disaster, the fifth block of the Chernobyl Plant was under construction and nearing completion,â a Flyability spokesperson said. âGiven the rush to leave, there was no record of whether the holding pools in Reactor Five had ever received the depleted uranium fuel bars for which they had been made.â

This Is How a Laser Weapon Torches Drones Out of the Sky
Posted by Quinn Sena in categories: drones, military
This simple laser demonstration is actually a great crash course on how these anti-drone weapons work.
At first glance, this video is just a simple promotional video for Rafaelâs Drone Dome, an anti-drone laser weapon. But at just two minutes long, it does a really excellent job at explaining what how a laser weapon actually takes down a drone.

Hydrogen-powered VTOL drone flies for 3.5 hours
Posted by Quinn Sena in categories: drones, energy
VTOL (vertical take-off and landing) drones are quite versatile, as they combine the vertical flight of a helicopter with the fast and efficient forward flight of a fixed-wing airplane. This one features an extended range, thanks to a fuel cell power system.
The experimental aircraft was developed by a team at the Netherlandsâ Delft University of Technology (TU Delft), working with colleagues from the Royal Netherlands Navy and the Netherlands Coastguard. It has a 3-meter wingspan (9.8 ft), weighs 13 kg (29 lb), and features 12 motor/propeller units distributed on its two wings. Even if several of the motors fail, it can reportedly still fly and land successfully.

Robotic dogs to start patrolling Florida military base
Posted by Dan Kummer in categories: drones, military, robotics/AI, surveillance
Fido, meet F1d0.
Newly developed robotic K9s will soon be prowling Tyndall Air Force Base in Panama City, Florida, to enhance security and surveillance patrolling, WMBB-TV reported Monday.
The 325th Security Forces Squadron, which handles security for the base, said the robo-dogs are weatherproof, four-legged, unmanned patrolling drones that have two-way communication abilities and high-tech sensors that cost about $100,000 a pop, the outlet reported.
