P-47J


P-47J_late



There was a prototype but you could also base it on some sort of field mod.
I figure two slots would be good for an early and late version, although performance would not be too far off from either.
I can talk about this more with whoever makes the slots.

thanks

Okay, I will do two slots for you. Contact me via pm with further details on what you want ;)

Oh and you need to remove 2 of those guns, the XP-47J had 6 only and it reached 505 mph at height. I can also help make a basic flightmodel for it if you want.

thanks for your interest.

Its interesting to see the improvement that the different nose made for the aircraft.
Probably something that never went into production because it required the use of a fan which made it more mechanically complex.  It was also not really needed seeing as the plane was capable of reaching near those speeds with a few tweaks done in the field.

Well it also does have a much more powerful engine in it... it's not just the nose modifications. Also has a turbocharger or something which the other p47's never had.

Is a bit similar to the xP-72. Will look great in a very late war scheme and Generic schemes like in the pic. Look

I get that it was a P-47C with the R-2800-57C engine which was also added to the M prototypes.  They were the same plane other than the nose, but also take notice in actual photos, they did other modifications similar to the P-40 Ns to help lighten it.  That probably accounts for the improved climb rate.
It would've been a remarkable interceptor if the allies needed it.
When i say planes in the field achieved similar speeds, i mean they had tweaks done with similar engines, and improvements to the waste gates to improve manifold pressure.   Probably not able to achieve the same rate of climb obviously, but the Ms and late Ds topped out between 470 and 480mph.  Its said having the pylons removed made a big difference too.  When it was deemed they needed the Ms to napalm targets, they stuck the pylons back on which probably neutered those top speeds a bit.

Well I think this would be quite close to how it would perform...



633 kmh (393 mph) at sea level, 816 kmh (507 mph) at 10,450 meters on bubble top version, P-47J-Late. 628 kmh (390 mph) at sea level, 810 kmh (503 mph) at 10,450 meters in razorback version, P-47J-Early. Of course il2 compare is not completely accurate, the aircraft will only perform to how well the pilot can fly it. However it gives a pretty accurate overview of an aircraft's performance as you can't go and test at every single height etc... I've done some testing to see if they meet the figures with various aircraft and il2 compare is pretty dead on :) These are all numbers for radiators closed also they are all True Air Speed figures, so not what your speed bar says as it reads Indicated Air Speed by default unless you have modded it.

Actually all the models of the P-47 had a turbocharger.   It would be impossible for a plane to have a ceiling of 42,000 feet without one. 

Designed by Alexander Kartveli, then Republic's chief designer, the P-47 was built in response to the USAAF's recognition that it needed a heavier fighter than those presently in production or on the drawing boards in 1940. Kartveli adopted an unconventional approach to designing this aircraft. Recognizing from the outset that it would need not only a large powerplant but a turbocharger or supercharger, Kartveli began by designing the duct system that provided the turbosupercharger with air, and then building the fuselage of the aircraft around that system. This allowed him to place the bulk of the turbosupercharger in the tail of the aircraft, where its weight could counterbalance that of the enormous engine, a Pratt & Whitney 'Double Wasp' powerplant. This engine was a 2,000 HP radial engine, with eighteen cylinders in two rows. One of the recognizable features of the P-47 is the turbocharger exhaust outlet under the rear of the aircraft. This placement actually added a few MPH to the plane's top speed, generated by the few pounds of thrust produced by the exhaust flow -- a primitive jet assist.
