Running Schneewittchen's electric motor
Ғылым және технология
Testing Schneewitchen's electric propulsion. All parts besides motor, battery and inveter were produced by us. This includes critical parts, such as the motor carrier and propeller shaft. Motor and inverter: HPD16 and MC300 from Geiger Engineering. Propeller: 1.4 meter Helix folding propeller. The active power consumed by the motor was about 15 kW at a speed of 1950 rpm. The inverter showed an efficicency of up to 95%. At about 1850 rpm the propeller stalled, and volume increased so much, that the camera's microphone wasn't able to capture the full sound.

i have been watching for quite some time and I can say I have never seen such precious build from grounf up. I wish you all the best and hope to see maiden flight soon! best regards

Looking great, well done.
Very impressive I have been following
Cool channel. Best wishes Sir
Once the plane is up in the air the propeller will unwind so I wonder if the stall is relevant considering it's a static test.

Stall should be no issue in the air. Once there is some air flow, the relative angle of attack will be reduced avoiding stall. The volume in flight should also be much lower. It was rather of academic interest and a measure that the expected maximum power was reached ;-)
Just coming across your page. I'm curious if this is still an active project?

Yes, it's still active. We've been reporting somewhat less in here, but the project is still moving on forward. We post updates more regularly on Facebook and Instagram: instagram.com/hortenmicrolight facebook.com/hortenmicrolight
so when will Snowwhite have wings ? ;) can't wait !
Wow
Wow that prop and motor sounds quite nice. But that poor bush haha. Also didn't know you would go electric! But for short hobby flights it seems the best way. Can't wait to see more! Do you have any comments on opener's blackfly? I recently seen that and thought about your project. The blackfly is a pretty ingenious design (in my totally unqualified opinion haha). But it also seems like something that would be one of the easiest designs to build yourself at home. It's the closest concept I've seen so far that seems like it could become an affordable short range flying car.
Please do an update!
Great! Please inform the size of propeller.

It's a 1.4 meter folding propeller by Helix.

@@andreschavarria1450 Thanks, I wrote before I read. I'm sure you know your efficiency would drop with a smaller diameter & 3 blades but with more rpm delaying the stall. Flying wings & electric power....marriage made in heaven. May your progress go smoothly!
You didn't even take off!
