I think that it was from a wind generator of some kind. It almost certainly was not used on either an airplane or a dirigible. Seems to me I just saw some of these in the Napa Valley in the vineyards recently. I'm not sure why it needs metal sheathing, though.

It's not a great picture, but you can see one from the side in this picture taken in the Napa valley. I'm not sure what exactly they do.
