Can Anyone ID The Aircraft From The Engine?

[Brigand]

I recently bought a couple of small canvas prints, and one of them is the below image. Can anyone identify what aircraft it is? I'm assuming something American, as it looks a bit like a P-47, however they have a small scoop at the bottom of the cowling, and the wing you can see appears mid-or-high mounted, so counts that out.

Brewster Buffalo perhaps? I think they just had three props though, not four. Anyone have any ideas?

F8F Bearcat? Some a/c were fitted with either 3- or 4-blade props

Possibly, although the Bearcat in this image has a smaller opening around the cowling. Details on the prop look a bit different too, but the wing alignment looks about right for the two.

Antonov AN-2

Here's a colour version:



The wing seems too high for a low wing monoplane.

It's just the angle. Note the prop in this image.

Ooh, I think we have a winner here, an Antonov 2. Engine looks the same, wing and the slight bit of colour scheme you can see on the picture as well.

Good job PH'ers, that's been bugging me for a while now!

The only thing exactly the same is the little lumps sticking forward around the spinner, whatever they are (something to do with constant speed?). So you have to wonder whether any other a/c had these.

Counterweights maybe?

Probably both to help avoid oscillations in the pitch control gears (by increasing the inertia of each blade around it's pitch centre) and to provide automatic feathering in the case of loss of oil pressure to the pitch control hub)

I think they are to assist in feathering the prop. K9-BA adapter.

They are counterweights to increase the propeller pitch on loss of oil pressure. Without them you wind up with the pitch decreasing and run into an engine overspeed issue. Most serious aerobatic aircraft have counterweighted CS propellers.
