Could someone explain me why does the F100-PW-229 mounted on the F-15E has a power loss of around 5000 lbf when the F/A-18’s engines have a loss of 60 lbf and the Su-27SM’s have a loss of 600 lbf???. Channel loss? Maybe. It does seem a bit weird when you look at the intakes of said planes. The Su-27SM has some grates that i suppose contribute to the channel loss. The F/A-18’s intakes take a huge turn inward and up so the blades from the turbine are not even visible. The F-15 has a straight (more or less), visible turbine. Would someone that has more knowledge on the topic help me understand this matter or is this just Gaijin being “Meh. We don’t care” again??
F/A-18 has overperforming engines, thus overperforms in acceleration.

Also thrust with channel losses are shown for V=0 H=0(useless). If you think that thrust is wrong you can compare game with speed and acceleration charts from manual.

And the Su-27 losing only 600 lbf when the F-15’s losing 5000?
Ignore him, we have installed thrust charts for the F-18, the thrust is accurate. What is likely the problem is that general electrics stated bench thrust is inaccurate as the engine was intended for export and mounting in numerous airframes.

You mean like how the F-18A matches the acceleration chart in the manual?
What manual, i know only gao’s report.
It’s not usable for reports, the performance data appendix to the flight manual. It’s available on Google if you search for the TO number.
Is it distribution statement A?
I don’t know, it is just the appendix. That’s why it can’t be shared, but it has been on Google for ages. That’s why I haven’t shared it here. You can compare the in-game performance to the document at your own leisure.
As an aside, what are the chances gaijin matched the in-game performance to a restricted document almost perfectly by chance?

Thank you guys, but this still does not answer why the Sukhoi losses a little bit of thrust when the Eagle losses a metric ton of it.
Both intakes seem pretty straight. Hell, even the F-16 that has an even more bent intakes is able to generate more thrust
because Gaijin compensated for the excessive drag of the Su-27 with engine thrust.
So they are giving Su-27 special treatment?
No, they were just trying to fit their shitty FM into the schedules of a real airplane.

Oh so they just messed up the other parts and adjusted for it? I thought you meant that Su-27 was just really draggy and they gave it more thrust so it would be good
The Su-27 has low drag, but Gaijin couldn’t simulate it properly, so he just gave low engine thrust losses. In fact, all planes suffer from this: the EF-2000,the RAFALE, and the Mirage and F-16

Except for F-15 it seems, they just don’t seem to care about it since it has so much channel loss when it’s a straight shot to the engine
The F-15 also suffers from this when installing an engine in an airplane, you can safely remove 1-2 tons of thrust.

Then all the other planes should have 1-2 tons of thrust loss, but they dont
Well, probably best would be to compare it with existent ghraps… if there is any aviable and safe for posting.
Can say surely that F-15E underperforms a lot in case of non-afterburner speed at high altitude
