Propellers C-46 And C-47

Tue Sep 22, 2009 1:34 pm

What were the diameters of the propellers used on
the C-46 (three bladed and four bladed) and C-47 aircraft?

C-47: 11.63 ft according to http://www.philskies.net/library/Kom...F-Putangina/PAFAI-C47/aircraft.cfg

Ptrjong:

I have a diecast model of a C-46 with a broken propeller. The scale is 1/144.
Aero Club (England) makes a C-47 propeller in that scale. With your info,
I know that the C-47 propeller is too small (11 feet vs 14 feet). Thanks for
your reply.

Yes, I guess it's rather larger since the C-46 is a much larger aircraft.

Cheers

Which C-46 prop are we discussing?

I am aware of 2, a 3 bladed hydraulic unit, I want to say it was an Hamilton Standard.

The other one was basicly the same 4 bladed electric prop that was used on the P-47, P-61 and B-26.

The broken prop on my 1/144 scale C-46 is the three bladed prop. If I could find a correct prop (three or four bladed) I'd go with either.

Could the 3-bladed Ham. Std. prop be identical to the ones fitted on DC-4's?

FBU:

good suggestion, the DC-4 propellers (each) are 7' 4".

I will see what is available in 1/144 scale

thanks

I want to say no because DC-4's ran Wrights and the C-46 had Pratts.

actually now that I am thinking about it....The Corsair also was running R2800's and the early ones had a three bladed prop..I don't know who the maker was though.

The DC-4 used almost exclusively the P&W R-2000 Twin Wasp. Some Canadian developments, almost all prototypes, used a variety of P&W R-2800, Wright R-1820, and on the DC-4M, R.R. Merlins.

In both cases they were Ham. Std's. The P-47 used 3 different Curtiss Electric props and 1 type of Ham. Std. The B-17 had Wright R-1820 engines and used Ham. Std. props. The B-24 had P&W R-1830 with Ham. Std. props, except for the LB-30 Liberator II which used Curtiss Electric props.

Disregard my previous post on aeroclub's site. It should be www.aeroclub-models.com. The code for the 1/144 DC-4 props is W030. You get 4 of them in the set.
