 |
|
I started a thread here a while back about an "alternative power" airplane. I finally found that the folks at SONEX, apparently working with the Aero-Conversions people, (VW Conversion specialists out of Oshkosh) have put together a proof-of-concept flying version of a practical electric airplane. Okay, it's "practical" if 45 minutes is your typical flight profile. Hey, I know a lot of builders of experimental aircraft who get less flight time than that! It would work for me in the Florida Keys.
You go out and fly for half an hour in the morning, bypass the fuel pump on landing, plug it in, and go fly again in the afternoon.
The engineering is fascinating. The motor is the size of a coffee can. Well, yes, the batteries do take up a the rest of the room. But, it looks like it is all "firewall forward," I'd still like to tuck a fuel cell in there somewhere. You could do this in a 701, couldn't you? See it at THIS LINK.

FYI, Sonex and Aero-Conversions are the same people.

I've got to stop you right there. I don't believe the aircraft has ever flown.

I attended the press conference where John Monet spoke of this in public, and I took these photos of the plane and engine.
http://picasaweb.google.com/Patrick.Hoyt/ElectricSonexN270DC
Other notes from the press conference:
A longer engine = more watts = more power.
It's a "zero maintenance" motor. No user-serviceable parts.
Total of 900 batteries in "10 packs".
Charging and balancing is a challenge. Dangerous. (pieces removed so as to not be photographed).
270 volt DC, 200 amps, 16,000 KW hours.
Doesn't care which direction the propeller turns. Prop brake...?
Proof-of-Concept - not available at this time.
Total Sonex investment to date is < $30k.
Sonex is not planning anything related to diesel technology.
Alternative energy seems to attract a lot of nut-cases. Sonex wants to keep a low profile.

That <$30k investment always gave me pause. Sonex isn't doing any cutting edge research on less that $30k.
That electric plane was nothing but something to get folks to the booth.
