I think you’re right that it is a small airplane propeller. Maybe for a drone or for training purposes?

I will show it to some of my friends who are into RC aircraft.

Maybe for an ultra-lite of one of those backpack powered parachute things. I say too big for an R/C-the plane would be about half of full sized!

Fan blade for industrial use.  I worked in one of their plants as a Summer job many years ago.

Neither of my RC airplane guys were at our monthly meeting yesterday. I emailed a photo to each, but have no reply.

That reminded me-I stripped out a big industrial exhast fan out of the building I'm working on, thinking I could make something cool out of the fan. Its about 30" wide with 6 big heavy aluminum blades on a shaft with 2 bearings. Well, the thing sat in the garage for awhile then one day it was fairly windy, so I grabbed the thing by those 2 bearings just to see if it would spin. It started out slow, but after just a few seconds the thing was doing about a thousand RPM and I figured I'd better step back out of the wind. As soon as I moved, gyroscopic or centrifugal or whatever took over and spun the fool thing around and into my leg. It cut thru my carhart bibs and put a fair sized gash in my leg  before I could turn it loose. Now I think I'll hook it up to a generator instead of a wind chime!

That sure does look like what I have here. I may put it on an electric motor and see how much wind it will put out.
