Is the P47 planned to be released with all the external loadout directly ?

Thanks !

 

For me they can realese it even w/o wings :P

Btw how much p-47 could take ?? anyone know ??

hah when was it when you flown 67" for 30 minutes. Stop talking about keeping speed up, this is not a problem.

i just dont believe that you flown 67' for 30 minutes it crazy amount of time in sim.

yes every one complaining about this and only you can fly 67' for forever hmm.

You don't read the forums too much, right? I did the test together with a forum mate and yes, he (like you, thinking that was impossible) found the same, you can fly indefinitely with WEP engaged while keeping your speed high :lol: . And that was during the P-51 engine bug killing everyone's engine. But you know, some people still know how to fly :thumbup:.

P-47 was delivered to the USSR and was tested, disassembled, but was not widely used because of Eastern front specific conditions.
I know it was Yo-yo, but I guess he meant something about using Russian tests with Russian fuel to model the P-47, which nobody said nothing ever.

BRAVO DCS designers

 

The P-47 is my favorite WWII aircraft and the thing that I look forward to the most about DCS WWII.

 

The problem with the P-47 is it always seems like it's over shadowed by the other planes... so I thought it would be cool to start a thread devoted strictly to the P-47. A place where P-47 fans can share facts and stories about this awesome plane.

 

There's several documents on this site...but here's one that I found particularly interesting:

Any other fans of the P-47 out there?

 

:thumbup:for bringing to us the fabulous P47 Thunderbolt,all I need now is the "Chance vaught Corsair" and Ill be as happy as a pig in the Brown stuff :thumbup

So pls give me some more data so i can test it.

What speed

1st or 2nd speed of supercharger altitude, temperature etc. I would like to see by my self.

Radiators auto or manual etc.

I didn't put any special requirement, just wanted to test. IIRC it was in Caucasus free flight mission. I didn't climb more than spawn altitude, so maybe 5-7000ft I think, even lower. Radiators auto, of course. You don't need to do nothing special, just run 30-67" and keep it there with the speed it reaches, you can move however, I did some wide turns and turn around and back when I was getting out of the map, sought for an aerodrome when I run out of fuel, because yes, I run out of fuel there just using WEP all of the time. Landed on fumes, just to see how it behaved lowering speed and so after a so long ride but I noted nothing special, landed safe and sound. Also on ground I kept engine running a bit but didn't blow up despite radiators being out of the air flow then. I thought all of the time it would blow, but no, while keeping your airspeed high and temps in green it will not. I think water temp got just a hair above the green at some point and I tested if manually opening the radiator would lower it, and it did so rad wasn't fully opened at all (which intrigued me), but back again to auto it was just fine there. I don't know what more details I could tell you, just that, keep it fast and be gentle, really gentle when manouvring. Don't remember exact speed, but it was 300+ to 400 all of the time (and what not at 67"). Have a go, at some point I switched on my cell chronometer for fun expecting the blow up time but didn't happen, it was 27+ minutes (probably a little bit more until I put the timer) at 67" and I believe I could do much more shouldn't I run out of fuel :thumbup: .

I would like to submit also that even though the Jug wasn't the best fighter in terms of climb, acceleration, etc, that when flown right by experienced pilots vs a poorly trained Jerry it was still devastating. Reference the Hell Hawks' record against German fighters, and many times they even started at a disadvantage since the Hall Hawks were a purpose built ground and pound strike unit.

I only blew the engine when I mishandled the prop pitch, more specifically overboosted the engine at 2700 RPM. Once I realised it wasn't nearly as fragile in higher RPMs, I've given it what for without a failure since.

 

Just a little tip, not prop pitch but prop rpm.

You can't fly indefinitely with WEP, the engine fails at a random point after engaging WEP.

 

 

 

I wonder how the P47D engine will perform. I think it has 10minutes of water injection for WEP. Also have a few extra levers to play with for engine management.

ED is reading P-47 manual,it says 10minutes of WEP max, but we are making hardcore sim guys right ?? cant be so easy, we make that p-47 will blow up after 5 minutes, eveyone agree??

any objections ??........................................

Ok lets do it :) oh dont forget to implement dice rolls and timers too.

True, but one of the reasons why the pilots loved jug so much was the reliability of the big old radial in front.

That is very true but do not forget that they were taught how to manage their engine and took those lessons to heart. They never abused their engine unless it was a dire emergency and when that did occur, they reported it to their crew chief who then set about conducting a thorough inspection, and making repairs if necessary.

 

 

 

Don't forget that one of the components of this terriffically accurate and realistic simulator is the absence of any real fear of damaging the equipment you are simulating the operation of, much less fear for your life!! :thumbup:

"No detonation was observed in level flight up to 65.0" Hg. without water and 70.0" with water. No detonation was observed in climb up to 65" Hg. without water. Detonation occurred at 65.0" with water in climb but was remedied by using a No. 18 water jet. Cylinder head and carburetor air temperatures remained below the limits in level flight. Excessive cylinder head and carburetor air temperatures were encountered in climbs, limiting the duration of any climb to a point where limits are reached."

Exactly but engine is nto going blow up instantly when you push engine ti its limits

Not true mate. You break the engine after WEP engage lol.gif .

That's not true mate. There's no timers in DCS, you mistake with others so called sim... caugh, caugh, well wannabes out there.

 

IRL there's no timer either, the 10 min limit is just an engine wear measure, they didn't want you to wear the engine in the very first run what it was meant to wear in 10 missions meaning an engine change and a lot ground crews work (or even don't making it back in long range escort missions), therefore the limit. 5 min limit in T/O per manual means only you're slow and with an already hot engine, so "limit" is even lower because wearing is higher in that poor cooling situation.

 

 

But IRL should you keep temps in the right spot anything prevents you from running all day long at WEP, just engine wearing (and bills and lack of spares in a modern Warbird). High temperature is the only killing factor of the engine. In DCS it happens exactly like that as I said earlier here and you can do it only keeping temps in green, which is not feasible in combat where you're supposed to manoeuvre, change speeds, dive and climb. There is where you kill the engine, not because the 67" or whatever you use but because you prevent the engine to be properly cooled while in combat.

 

I don't expect P-47 engine to be modelled any other way either as all the previous ED modules uses that kind of modelling where airflow in the radiators determines Temps, hence your engine's life (IIRC Yo-yo said so several times). Here I guess it'll be airflow in the engine cylinders, and Turbo intercooler system which is why this engine is harder to model. And that's not only realistic as it should be IRL, being modelled like that it happens to be a sign of good piloting if you manage it as it's meant to be. That good this simulator is.

 

 

 

But all of that, just don't believe me, you have the software like me to test it by yourself. Go and see :thumbup: .

 

 

 

S!

Oh, there are timers in DCS.

How can you explain that, when i landed p-51 turned off engine everything was fine, then after about 5-10 minutes sitting on the ground with engien turned off i heard loud bang and after this engien didnt want to turn anymore. Engiewn just jammed it self sitting turned off couple minutes ago :)

If you realy think that high temp is only killing factor in engien you are mistaken ny a lot.

I alwayes keep temp below max values in p-51, i would not tell anything if engien would die after running coolant too hot or oil too hot.

i dont use 67"3000 in combat i rearly use 61"3000 in combat i use those only in running away from bunch of enemies, just going streight to my airfield.

I use 2700 46" in combat

oh for sure and proper engine management is what we need, i just dont want her to be as bad as the dora where the engine goes as soon as you start thinking about using wep

Here is a great read for all P-47D fans out there with LOTS of tips on not just engine management but aircraft handling too from the pilot who flies the P-47D based here in the UK (G-THUN).

It's going to be a completely new beast and a great new challenge for me after flying the DCS Spitfire for so long!
