Fokker D.VII (MÁG) 1/48 (Eduard)....

[Lucky13]

Why is the propeller looking like this, it definitely looks odd....

Jan, that's an option ...

Why are the serial fokker DVII MAG engine cowling and radiator so different from the V22?

Hello, I got the eduard 1/48 scale combo and I wonder why the serial is so different from the prototype and how close the eduard kit is to how it was suppose to be as an austrian plane. Source is this build: Fokker V 22 Thanks for your answers!

It looks like the Austro-Hungarians liked the Knoller-Jaray prop ..

The W.K.F. DD type C no.80.04 was tested with the standard propeller as well ... so an option ...

Much obliged my friend!
That's some weird props, made me think of contra rotating propellers first, but it's too early for that, isn't it?

Why this way?

 

[Wurger]

A couple of sources says that the propeller was the contra-rotaing prop. But in fact , it wasn't. The images with the W.K.F. Dr.I in, clearly shows the spinner doesn't allow to move the two props separately. IMHO the prop was used because of the power plant to limit the head drag and keep the correct trust to the engine maximal power.

And more info ...

The special four-bladed propeller actually consisted of two two-bladed propellers intentionally not mounted together at 90°, as clearly visible. An Austro-Hungarian patent covered these propellers, which were produced by the Jaray propeller factory in Vienna. This type of propeller was only used by the Austro-Hungarian forces.

That asymmetric prop is not all that unusual, U.S. auto makers used a similar concept for some of their engine cooling fans in the 50's and early 60's.
