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…

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…
