The rated power of an electric motor can vary wildly; it's not a fixed quantity like an IC engine. If you fit a larger prop, or run it at a higher voltage, it will draw (and hopefully produce) more power. However it'll also produce more waste heat, and may well be less efficient. You can run it way beyond the rated power for a few seconds, or overheat a ...

FLÜGEL World Directory Of Light Aviation 2019/2020 - English PDF could be a good starting point. On pages 278 - 281, a total of 71 lines of electric motors from 42 manufacturers are featured. Disclaimer 1: some data fields are incomplete for many of the entries. There are German, English French and Chinese versions in paper and pdf, starting at €8. Here's ...

An automotive analogy is found in Formula E racing. It never considered "refueling" through a power cable, instead opting for swapping entire cars mid-race. Its parent company is now trying battery-swap stations for consumers, if not yet for the race cars. So, replacing an airplane's depleted batteries with fully charged ones from the "tanker" might work. ...

Tesla now has batteries to the point where you can recoup energy for a 4-hour drive in 30 minutes. That's in full-on production, you can buy it and do it at retail today. The biggest challenge Tesla has is keeping the batteries cool during this slam charging; and in an airplane we have a huge surface area being blown by a slipstream. Have the battery ...

This question shows the fallacy of electric propulsion in its current state. The electricity needs to be generated using non-environmentally friendly means. Even solar power is unfriendly due to the process for making the current panels. Hydro and geothermal power would not work in this scenario. Even the production and disposal of the batteries have ...

This would certainly be possible, but the current status (pun intended) of the battery technology makes it pretty much pointless. The charging would simply take too long: for example, Eviation Alice has a battery capacity of 900kWh. If we were to charge, say, 75% of this (because you would need to have some reserve capacity in case charging does not work ...
