P47-N Climb

[Mojava]

 Does anyone have any data on the climb rate of the p47-N?  I've found a few things about the M model, and it's rate of climb was very much superior to the p47-N.  Here is the data I have dug up, P-47 N Climb, it seems to be a bit better than what we have modeled now.  I may just be looking at the wrong stats, any help would be appreciated.

P-47N carries over 1000lbs more fuel than the P-47M. P-47M has main and aux just like a standard P-47D-40 does. P-47N has a LOT of fuel in the wings.

You lighten a P-47N by draining the wing tanks and with WEP on it'll start performing more like a P-47M.

P47N with it's extra weight in a wider wingspan fuel tanke (even empty) and other various things that aren't mentioned here add up to a significant amount. 

Remember, the M was actually a P-47 D-27 modded to increase pressure on the turbo and with a new engine.

At nearly same weight, 16,300lbs I got it to climb at about 3200fpm right off the deck to few K of alt, before the rate started dropping. But I used .speed command instead of auto climb. IIRC some 10mph less then usual auto climb speed.

Note
Numbers may not be 100% accurate, since I tested a while ago.

Also, this chart is a bit better: http://www.wwiiaircraftperformance.org/p-47/p-47n-republic-wep.jpg

It just so happens that I have climb data on all four P-47s.. Don't fake being surprised.


Our P-47N climbs better than that shown on the chart referenced, especially above 5,000 feet. Note that the weights are within 300 lbs of each other. I plotted the AH2 P-47N, -25 and -40 on the chart for reference.

As Widewing has pointed out before, "N" sans wep has same horsepower as D40. with heap much more weight. Lotsa guys use wep on N climbout, which rather defeats purpose

600 lbs or so more empty weight I think. And N has a larger wing. I think the "problem" with the N is the massive fuel loads it can carry. Remember, the N can fly for the same amount of time on 50% fuel that the D-40 can on 75%. Don't overload it, and there is not much difference on MIL climb D-40/N.

 Thank you for the information fellas.  <S>

the M was totally different than the N in  every way.

it had the same engine, but was propped and tuned different.

the N was designed to be a long haul fly to fight escort with good range, the M was designed, to be a monster.

P-47M = perked

P-63 = Perked

The last 2 perk planes needed to be added to the set.

No.
P63 would not be perked, P47M could go either way.

[Wingnutt]

No.

if we got the 47M and it wasnt perked, the whines would never stop.. a jug that does 400mph below 10k.. 

[Motherland]

The 109K does 400 at 5k 
Really it's not that fast.

jug turns better, has better high speed handeling, and better firepower at range... so add to that the speed of a K4.. it would be a tad unbalancing

interesting note though, the M never carried ord, it was a pure dog fighter version of the jug.

[Motherland]

I'll give you high speed handling, but the K4 can turn with the Jug in a slow fight.
