Hello,
Who can help me with this propeller?
It's in a bad state found in an attic.
There are no markings on it.
Diameter is about 1 meter.
Is this a drone propeller?
Greetings

"Probably", although maybe an auxiliary prop pf some kind.

Thanks for the reply!
Without markings it's difficult.

THE only thing I've noticed is that it is a pusher prop.

Hi Geertse,

Auxiliary props have the "shape" of a pusher which would be "turn forward". It is because auxiliary props work the "reverse" of prollers making the plane flying.

Hello pmdec,

I know but ,with a diameter of about 1 meter isn't it to big?

Hi,

Yes, 1 meter is quite large for an auxiliary, but 500 Watts Levasseur were 60 cm in diameter. Perhaps for some higher power there was some larger ones on "bigger" planes of the 20's or 30's?
Without markings, I am afraid it is impossible to know and a pusher for a drone is not excluded.
