eVTOL Noises Off (Or at Least Significantly Quieter)
Reducing the impact of ambient noise eVTOLs will generate will be one of the keys to the implementation of successful UAM/AAM commercial operations.
Teaching eVTOL Batteries to Teach Themselves to Self-Diagnose
The lithium-ion batteries at the heart of the eVTOL revolution will be tasked with performance gymnastics unlike those asked of any electric-powered vehicles in history. Start. Stop. Take off. Fly. Land. And then . . . do it again. And again. The batteries will discharge power and need to be recharged dozens of times a…
Weather or Not – AAM Operators Need to Know
As advanced air mobility (AAM) and urban air mobility (UAM) operators prepare for takeoff, perhaps the one constant they can count on is weather. From hot today to chilly tomorrow, eVTOL operations are especially sensitive to weather. Scientists and researchers, Ashima Sharma, Jay Patrikar, Brady Moon, Sebastian Scherer, and Constantine Samaras conducted a study sponsored…
Drones – The Good, the Bad, and the Amazing
Drone technology is being used in many creative ways, not all of it good!
Toroidal Propellers May Quietly Pave the Way to UAM Package Deliveries and More
Making drones quieter by redesigning propellers may be the key to public acceptance of unmanned deliveries.
Vertically Aligned Electrodes May Improve Battery Charging Times by 500%
The linchpin of eVTOL transportation’s commercial success (read “profitability”) fundamentally lies within that lowercase “e”– the electric part of the acronym. But, one of the challenges eVTOL developers and manufacturers face is their ability to quickly and efficiently keep their lithium-ion powered vehicles sufficiently charged to keep them aloft. The Challenge of Keeping eVTOLs Charged…
