Spad 13 Propeller Question

[II./JG1_Kadin]

Is the propeller on the Spad placed backwards or spinning in opposite direction than it suppose to?

I was under the impression that the rounded part should be on the leading edge and the sharp on trailing.  Of course my aeronautical knowledge pales to most so please forgive me and by all means enlighten me if it is possible

There were several props used on the SPAD but I'm not really sure what you mean.  Got a pic?

Well, it may seem weird, but if you look at the Blade Angle, the Prop is spinning correctly. 

[II./JG1_Kadin]

The AOA of the blade seems right for the spin direction and the shape of the propeller lead and trail edge also seems right but it is the cross section of the blade that seem a little odd to me.  The thickest part is towards the trailing edge and I though it was suppose to be closer to the leading edge.  Then again, those early days the prop design was coming from ship screws and maybe that is why. 

[6./ZG26_Klaus_Mann]

It would also make a thin bladed Propeller a lot stronger, making it thickest at the most stressed Part.

HA !!!

 

OK, I think I see what you're seeing.  (I just bought Flying Circus.)  It is rather subtle though it looks to me like the 3D model is actually backward, the normally forward facing surface (the "back" or curved side of the blade) is actually facing toward the pilot and the "face", or flat side, is facing forward.  The fix, naturally, would be to turn the prop around.  It's not at all obvious due to the blade symmetry, if the scimitar prop had been modeled it would be screamingly obvious - lol.

The curved side was often the leading edge of a prop in these times.

 

See here. A SPAD13 prop. There were some different ones used, but often the leading edge was cruved and the trailing edge was somewhat straight.

That would be the scimitar style prop I referenced.  The game uses another, symmetrical blade prop ... like this one on Smith IV in the Smithsonian:  http://www.pbase.com/noyphoto/image/85989885 

 

What the OP is referencing, I believe, is when one looks down the length of the blade, from tip to root.  The airfoil cross section is reversed as if the propeller were put on backward, and I agree.
