P47 tips and Requiems Exvellent Videos

[Sublime]

I suggest anyone who likes flying the jug and has trouble getting better speed down low use this advice I got from one of requiems videos

First of all the intercooler - for some reason in my head I looked or thought of it as the same way as the inlet radiators on the La5FN which youre better off leaving wide open and forgetting.  Not so.  50% is good because it leaves them flush (theyre on the 'waist' of the plane)  above 50 they produce drag..

Most important though was interlockong the turbo and rpms!! What a great feature this plane has, and what a huge difference it made.  Alt + i and left shift + i (forget which is which) significantly has helped me with the jug keeping the speed up.

I literally am easily averaginh 30-50 mph faster almost across the board which shows how poorly I was utilizing all the features of the bird.

Just putting it out there... When I did this she flew a lot more 'reasonably' for me. Still no super hot rod but not the dump truck before

Do you fly with the turbo and rpms interlinked is that faster then just setting turbo to 100 percent constant

That's definitely a question I would like to see answered. I generally keep the turbo to 100, and I'd be interested in learning if there's some better optimal setting I've been missing.

Im not sure honestly.  I feel its perhaps optumal since youre linking things together and therefore its adjusting as you simply adjust the throttle.  Its hard to imagine that just leaving it full opem would be better than something that adjusted it based upon the pilots use of another device.

However Im notnsure.

For someone without many extra control axis' the ability to interlock the turbo was priceless

I thought the turbo was supposed to be linked to throttle not RPMs!?  At least i have just had it linked to throttle and achieve reasonalbe speeds to those shown by der sherriff in his video on the p47.  In his video he shows the p47 capable of 252mph on the deck, level flight with intercooler at 50%, cowling closed full.

It is linked to throttle not the rpm. I prolly mistyped

oh ok phew!  i thought it was supposed to be throttle.

You can interlink RPM, Turbo and Throttle all to one, though you lose a bit of efficiency I think. Interlinking doesn't make the throttle and turbo changes instantaneous with each other since the Turbo takes time to spool up to speed before you get best power.

There's no difference between interlocking turbo and throttle or just maxing both. That's why the linkage is even possible. It does, however, make it much easier to manage, especially for those without extra axis.

At extremely high altitudes you may have to disconnect the linkage to lower the turbo a bit as you can overspeed the turbo if you leave it at max.

Max level speed is generated for the P-47 at about 2550 RPM, not 2700 RPM. Like the Yak-1, the Pe-2, and a couple other planes, the propeller at max RPM starts to lose efficiency at higher speeds and actually causes a bit of drag, so you can eke out a bit more level speed by lowering the RPM. However, this will impact your acceleration and climb so anywhere outside of level flight your best bet is everything maxed out.

Thanks Sublime, but it's not my technique. I'm not reinventing the wheel or anything as my content is always based off an airplane's actual manual when I have it available because I expect the devs to make an airplane accurate enough which allows us to do so. The P-47 manual I used is here if you want to learn more.

I try and operate the P-47 by the manual and its pretty much how you would expect. However, I know that I've screwed up operating the turbo before and I haven't noticed any damage or problems from it. Do you know if its possible to damage the turbocharger by improper operation in game, or is it just that you don't get the most out of the machine?

I don't think that kind of damage is modeled, so you can operate the turbo or a constant speed propeller completely wrong and nothing will happen to the engine other than reduced engine output as far as I know. I've never tested it exactly but I do remember having done extremes like min RPM and max MP and had nothing happen.

Which in real life would cause detonation correct?

That's been my experience as well. With the exception of increasing RPM/Throttle too fast in the P-39 and killing the engine.

Hopefully one day we will get detonation and other engine problems modeled.

Bingo

[Stoopy]

Isn't detonation at least 'kind of" modeled in the sim in the FC D.VIIF?  It "pings" at high throttle settings at lower altitude, just as it did in RoF due to the higher compression available. I thought damage would be modeled as well even if only as a timer?

Yep, and pre-ignition is what causes a lot of damage due to detonation. Basically as detonation occurs the combustion chamber's temperature starts rising which leads to the fuel/air mixture sparking outside the normal timing because there are places that have now become hot enough to ignite it (instead of the spark plugs doing it). A simple analogy is to think of it how a heart can have an arrhythmia due to extra electrical impulses. The heart can't always get out a regular beat because it's being stimulated to contract at the incorrect time.

 

In the sim it should show up as a kind of engine roughness and loss of power, and then if left untended long enough it would start causing engine damage.

hey credits due where its due my friend, your videos have taught me the basics of all planes. I used to sort of dislike your videos only because you did a simple circuit around the field and I used to shout at you on TV 'what do I do about engine dogfighting or this or that: but youve started adressing it.

youre very thorough and a pleasure to learn from. cheers

I was TOTALLY unaware u could link those items and it TOTALLY changed my p47 perforamnce. that and the intercooler - i though they were inlets like a20s or LA5s.. jessh

I feel like predetonation is modelled in the game. Occasionally, if I let an engine get too hot, it starts running a little rough and I start seeing a 30-50rpm fluctuation. If I keep running hard and hot, eventually it fails; but if I pull back RPMs and start running it cool, the fluctuation still exists but I can fly for quite a while longer before the engine quits. I might be wrong though.

hyper trophic cardiomyopathy is a much bigger mouthful than detonation. And not for nothing referred to as sudden death syndrom

[VBF-12_Snake9]

Until something changes in game, to get best performance leave turbo at 100.  Other than wanting to fly by the real life settings, there is no reason to move it from 100 percent. .... I believe you will need to decrease around 29,000 feet but who flies that high anyway.

All 'sad but true'.

That just sounds like the overheating damaged the engine, and its possible to nurse an engine by pulling back RPM, throttle, and running it as cool as possible. It works for battle damage too.

I wish thst Jabos P47 campaign worked. Whatever bug thst causes the engine oil coolant to fail on take off is maddening. Any solutions or fixes
