Challenges and key requirements of batteries for electric vertical …
Typically, there is a trade-off between hover and cruise efficiencies: e.g., vectored thrust eVTOLs have wings for efficient cruise but are low in hover efficiency; …
Voltage Regulator (ext.) / How it works | IH8MUD Forum
A lot of you don''t like electric stuff and especially not complicated things like an external Voltage Regulator. So maybe it''s time to explain how this black box with …
Managing Range and Endurance of Battery-Electric Aircraft
wingborne flight. During cruise, the aircraft will deplete the energy state of the HVESS, reducing the open circuit voltage. A high-power thrustborne landing with a low HVESS …
