Electric and Hydrogen aeroplanes - feasibility and issues

[Justo Miranda]

That plane is going to need a very long wire

How close is Australia's aviation industry to going fully electric?

Multiple Australian companies are pioneering the country's electric aviation industry. So how are green planes powered, how safe are they, and what will it cost?

I think one big misconception about electric engines is that since they have fewer moving parts people assume they must be simpler and inherently trouble free. But the electronics and software needed to manage them is incredibly complex. This is an old but good interview that sheds some light on these engines:

The company is focusing on the retrofit market as the easiest path to market for its electric propulsion units.

“People say electric motors are much less complex than gas turbines,” Armesmith says. “And that is true physically, but functionally, and in software, I would say [motors] give [turbines] a run for their money."

“Controlling permanent magnet machines is complex,” she continues. “And the software around extremely fast-acting protection systems that can get ahead of an electrical fault is very complex. A lot of our development recently has been around that.”

Anyone know more about this? 500Wh/kg flown?
