Surprised they are not using linear opposed piston crankshaftless generators to make an extended range EV aircraft.
Smaller, lighter, simpler, cheaper, and more flexible about fuel.

- MobiusHorizons 1mo agoThis! Anything unproven makes the flight certification process longer. They already have to get their electric side certified, might as well make the backup generator as easily certified as possible.
- tuatoru 1mo agoGood point. Only have one new tech at a time. Generation II then.
- bitwize 1mo agoMy father, a mechanical engineer, was a tireless advocate of the hypocycloid crankshaft mechanism. In the 90s, hybrid vehicles with a hypocycloid-based generator feeding the batteries that make the electric motors go was the application he was going for, especially since hypocycloids function best at constant RPM.
- strictnein 1mo agoI say this with all sincerity, I love this sentence: "My father, a mechanical engineer, was a tireless advocate of the hypocycloid crankshaft mechanism." For some reason just reading that brought a smile to my face.
