Will Sodium-Ion Batteries Replace Lithium-Ion Batteries . . .
The ‘e’ in eVTOLs – electric – has, from the outset of advanced air mobility (AAM) relied on lithium-ion batteries to power the aircraft. But, if scientists from the U.S. Department of Energy’s Seattle, Washington-based Pacific Northwest National Laboratory (PNNL) succeed in their efforts to develop a sodium-ion battery, the result could be a real…
It’s 2023: Do You Know What the State of Urban Air Mobility Is?
Researchers around the globe are exploring the challenges and potential benefits of UAM.
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…
