P47M...Hmm

[Wolfala]

Both the 190 D9 and the P-47N are very mediocre performers compared to other LW planes sans WEP. Well, at 30K the Jug is a monster either way, but I'm talking typical MA alts.

The difference is, in the D9 I never find myself short on WEP when I want it, the P-47N, it is something you've got to think about constantly.

Kind of a tragedy too, because come on, an R-2800 with water-injection could easily pull 70" MAP without failing for ten minutes, you know it and I know it. But, got to be a limit somewhere I suppose.

There was a horey old chesnut about an engine - that was for purposes of certification run on a dynometer bench for 200 hours at WEP - which they tore down afterwards to find out which parts break. Then, there was an engine that when you mated it to the airframe and installed the baffling - discovered you couldn't keep the cylinder head temperatures low enough during high power operation and WEP to prevent thermal runaway, detonation - and eventually, engine failure.

Point is this - limits established for purposes of certification vs those used OPERATIONALLY aren't synonyms - NOR do they happen to cross paths every once in awhile. You have operational limits because - maybe you need to fly that engine again. That, and mechanically speaking - nothing good for the engine is happening while WEP is running, or ADI, etc. You've got the highest CHTs, Highest Internal Cylinder Pressures - and your detonation margin is the widths of a fly's pubic hair if you don't have the fuel flow set above the manufactures spec.

I read what I could on the P47 and the few pieces about the 'M' were all about the 56th FG where the engines were over boosted (beyond factory specs). It might be hard to model that. The P47N is the same airplane with more fuel tanks in the wing and clipped tips.

I have a book of jugs, and have posted about adding the M before, of course I got pissed on by the people who would rather add "more relevent" I.E. useless aircraft that wouldn't see use in the MA.

it was a pure fighter and could reach the dark side of 400mph at only 10K.

It would merit the 5ENY value the N carries (but does not deserve) and was the apex of the Jugs lineage, I dont think a perk would be warranted, considering it could carry no ord, ensuring usage of the other jugs in the plane set.

seems silly not to have it considering it meets all the criteria necessary for inclusion in the game,  and had historical significance (262 kills, etc etc)

negative, same engine, different supercharger, different prop, different purpose.

the N was built for long range escort, the M was built for raw performance and was superior to the N in every aspect except range.

Since the dev update. Any chance of the P47M added within the next year?

im for it  love those jugs

oops

P-47M is essentially a D-40 with reduced drag (no hardpoints for ord) and more horsepower.  It is about 30 mph faster than a D-40, climbs about an additional 300 ft/min, accelerates about 7% better and should turn a bit better because of the improved power loading.  Probably not an uber MA fighter (at typical MA altitudes) but probably good enough to see a lot of MA usage.  Below 10,000 feet with WEP engaged speed, climb and acceleration are similar to a P-51D with WEP.  Without WEP for either, 51D would have a noticeable edge over 47M (a 51 gets about a 10% HP boost from WEP and an 47M gets about a 28% boost).

I can offer specifics. The three YP-47Ms were re-engined P-47D-27s. Production aircraft were based upon the D-30. Originally built without wing pylons, they were installed later in Britain. P-47Ms didn't fly using 100-130 avgas. The 8th AF was using 150 octane fuel by mid spring of 1944. Using the 150 octane avgas, the P-47M could safely pull 80" of MAP, although 75" was recommended. This produced maximum speeds around 480 mph, even with wing pylons. Speed was rated at 473 mph @ 72" using 100-130 in stateside tests.







Thanks to the gents at www.wwiiaircraftperformance.o rg for posting the test data and images.

P-47Ms could and did carry under-wing ordnance. All were fitted with wing pylons in Britain. Below is an image of two 56th FG P-47Ms taking off with 108 gallon drop tanks. A full 108 gallon tank weighed 690 pounds. P-47Ms were not fitted with rocket tabs.

Preach it, Widewing

47M plz.

[StokesAk]

Yes Talen and how did i know u would bring this up?

[Grape]

I would be so happy to fly the P-47 M in the MA

[jolly22]

i have a ww11 aircraft book and it says that the p-47m is faster than a p-51

[Sancho]

it's a nice dream, eh?

Holly crap, when is the last time you posted here?
