The P-47D and the Turbocharger

Were there any reports, charts/manuals stating that it was available on good numbers by the time of BoPB operation ? If not, then we shouldnt have it ingame. But if it was available, then make a report with all the documents necessary and send to devs.

 

Just saying that the p47 should have 64' and not providing any document is the same as people asking for the G6 with MW50 and GM1.....

100 octane was the standard fuel at this time I think. The other main fuel was 150 grade fuel (I think it was called 44-1 but not sure) this fuel was used alot in the 8th AF anf they operated above the areas e will be seeing in-game even though they didn't have bases on the mainland.

 

EDIT: correct me if I'm wrong, I could be confusing things. Either way high octane fuel was used during the timeframe we will be seeing and it allowed the Jug 70"

And wheres the documents that prove all of that ? Anyways, if you have them, by all means, send a PM to the devs with them explaining your case.

What exactly are we trying to prove? The fuel use or the power it allowed the aircraft to use?

The  fuel use is already being discussed in another thread on the fm section.

The evidence of the power it allowed is something I can provide though.

Im not trying to prove anything, the ones who need to prove are the ones who made the claims.

http://www.avialogs.com/index.php/en/aircraft/usa/republic/p-47thunderbolt/aaf-51-127-3-pilot-training-manual-for-the-p-47-thunderbolt.html

Page 18 of this manual, published in 1945, shows the power settings for Grade 91 fuel and Grade 100 fuel. It states in part that the P-47 was designed to use 100 grade, but demands overseas limited them to 91 grade on the continent.

So its indirect evidence, at least, of 100 grade fuel being used in-theatre at least. Not conclusive evidence that it was always available or that it was surpassed by other fuels unfortunately. That manual has no mention of guidelines for fuel of higher grades.

Max takeoff MP is listed as 52" HG for 100 grade and 42" HG for 91 grade.  Max MP was limited to 15 minutes.

This pilot's notes, published January 25, 1945, is more specific to exact settings and includes references for WEP. It indicates the grade of fuel as 100/130. Max MP under WEP (water injection) is 64" HG for 5 minutes. You have enough water for 15 minutes accoding to the other manual, so presumably you would use the water multiple different occasions as necessary. 52" HG is listed as Military Power with a 15 minute limit.

Once again it doesn't talk about higher grade fuel, but doesn't preclude its use either. We would need primary source notes from the deployed squadrons or administrators of the supply in the region to confirm use of that fuel and what recommendations there were.

One thing I'm very interested to know is how they'll handle the water injection system? Water allowed for different W.E.P settings and you could have W.E.P. with and without water, how will they handle this in-game?

 

Will they just have one WEP setting and your engine blows if you go over it? or will they have multiple settings representing the use of water vs non water and allow for various times at wep?

 

The more I think about the more I feel that the P-47 is one of the most complex engines they will have to do in terms of power settings, WEP, time limits at certain power, etc.

 

Will they be able to pull it off and give it justice? or will they just simplify everything and kinda ruin it?

@Legioneod - that is a very good point, that is only sinking in for me as I read the thread. If they can model the P-47 CEM in a way that is both satisfying for the more nerdy  mechanically aware players and also practical from a programming POV they can surely model just about anything!

 

 

The AI has to be able to fly the beasts as well. I know the AI uses the full FM - at least most of the time. I assume that it uses some of the engine management helpers but I have never really thought about it. Does anyone know? Even to get the helpers right the developers do not just have to program the controls and engine, but also the rules the helpers and/or AI must follow in operating the aircraft. Quite a task.
