Fokker Dr.1 Prop ID

[JFM]

Hello,

First post here.

Looking to ID the propeller on one of Richthofen's Fokker Dr.Is, 152/17, flown March 1918. Triplanes often used Axial props, but they could also use Heine and Lorenzen, and even captured British props and engines. 152/17's prop does not look like an Axial--in the first picture it looks "Heine-ish," and in the second photo it resembles props I've seen on Sopwith Pups. Both photos of the same machine; second photo is undated but post-March 1918. Same prop, different angles? Different props?

So, I ask you, the more learned, for help. Any input appreciated!

Thanks for your time.

Hi Jim,

Your second photo, showing the prop with a high aspect ratio, is a Type 63 axial prop. I can't identify the prop in the first photo but I can tell you that I have records of Dr I props made by;

Axial, four types, all variations on the Type 63 design, all visually the same.
Heine, one
Lorenzen, one

There may be others of which I am unaware.

With regards,

Bob

Thank you, both.

I have the same information regarding prop types used on Dr.Is. That second photo throws me--the blades have the Axial angular trailing edge, but that lighting does me in. That lower blade looks as if it is curling back over on itself or something. I'm glad you ID'd it.

Thanks again.

Jim,

I think its a combination of a shadow and the colour of one of the laminations of wood. It's a type 63 Axial prop.
