Thread on the performance of the P-47

[Kurfürst]

Great to have this new sub-forum!

One question regarding the P-47 D that bugs me for some time: Does anybody know when paddle blades were introduced to them exactly, and to what extent they increased performance ?

TIA!

Hi Kurfurst,

The Evensville plant used the paddle blade prop.

Evensville built 889 P-47D-23-RE thunderbolts.
Farmingdale plant built 850 P-47D-22-RE Thunderbolts.

From what I read the only real difference between the D-22 and the D-23 was the manufactures choice of propellor. So far I have not seen anything on performance differences.

Will keep my eyes open for more info but maybe this will help answer your questions.

Kurfurst - the first kits came to the 56FG in the middle of January and were retrofitted to the -10 through -20 IIRC. Paul has the right factory original equipped I think. This obviously is not a 'specific date' but I would throw Jan 11 out as a near miss.

They significantly improved low altitude acceleration and initial climb performance according to the pilots that used both. I have never seen actual flight test comparisons.

The 355th never got them before they converted to Mustangs six weeks later

Maybe this will help...or maybe not! *-) This is off an old HD and I have no idea where it came from. I'd love to credit who put this up, but I can't.

The dashed lines will be for the "paddle prop". It was really called a high activity propeller.

Thanks alot for these!


Do you have any power settings (cruise max cruise, eco cruise, etc) for the R2800-59 in the P-47D? All of those specs are for the R2800-21.
