Wonderful. There are a number of home built electric powered aircraft but they have to remain in the experimental class. There is currently a solar powered aircraft in a round the world flight. Electric power is lighter in weight, form drag is diminished and no volatile av gas is required. Since the motor torque remains constant across the rpms, wonder if a variable pitch prop is needed. Or can the prop be fixed pitch? Aircraft engines are currently going thru a transition to aero diesel engines so the electrics will have some competition, but electric will eventually win the competition. Thanks for the link Brew. Cheers. |

I'm not sure about the whole thing, but electric motors generate most of their torque at low speeds, and max power less than halfway up their power band. Also they're less efficient at high RPM's. I would think that with an appropriate variable pitch prop, RPMs would be pretty much fixed at a lower speed than with a piston or turboprop engine, for much lower NVH in all regimes.
