4.11 overheat and engine damage test results

[jermin]

Well done! Thanks for the detailed information.

My question is whether aircrafts equipped with MW50 really overheated that fast in real life. According to the test it cannot even last more than 2 minutes in the game. The only radiator position that is useful for Luftwaffe pilots are full open. I can't think of any situation where other positions can be used.

And I can't persuade myself to believe those coarse Russian engines tend to has less overheat problem than German ones.

BTW, 109 K4 C3 appears to have a flawed auto radiator. You can notice the radiator flaps are not fully open even the engine has been overheated for a long time.

MW50 merely allowed higher boost pressures and the max time to run that higher boost was 10 minutes after which you needed a 5 minute break.

That restriction is totally separate from any other limitations on running the engine at takeoff/miltary power at low airspeed. If the engine had a separate restriction on for example time at takeoff power that still applied over and above the 10 minute WEP restriction.

Running MW50 did not magically give the engine the ability to disregard its normal restrictions its cooling properties were a side effect and minimal. People seem to think if MW50 was permitted for 10 minutes then the engine should last 10 minutes regardless of how you mistreat it. That is just silly.

Let me translate that first sentence, the most important of them all, for jermin.

"What is MW-50 operation?
MW-50 operation means: Temporary extraction of emergency power for the purpose of hoirzontal and climb speed increase, allowed by boost pressure increase to 1,7ata and simultaneous injection of MW-50."

So, as I told you before, it is not meant for the pilot to give him an edge in zoom climbing or general fighting, but to increase his speed to get out of trouble.

Where does it say it should be used to get out of trouble?

you never climb and accelerate during combat? What if your plane can not outrun the enemy aircraft on your 6 and it is more agile than yours? So will leave MW50 disabled and wait for enemy ripping your ass off?

Don't pretend to be a WW2 veteran, will you?

1. It can not last two minutes stationary on the ground without any air flowing through the radiators to actually cool it. That is what this test established as he tries to mimic a plane at stall speed at the top of a zoom climb. If your plane is constantly in that state you are a rubbish pilot.

2. Other positions can be used during 90% of a regular pilots flight time. Prolonged combat against top brass planes and pilots are rather rare actually. Even on a dogfight server, if you know what you are doing.

3. Exactly because of their rather rough nature they are more rugged.

Where's the difference? The engine still can not last over 5 minutes even during level flight.

2. Other positions can be used during 90% of a regular pilots flight time. Prolonged combat against top brass planes and pilots are rather rare actually. Even on a dogfight server, if you know what you are doing.

Have you tried it yourself? Fly some sorties in some hot servers on hyperlobby and see for yourself whether you will have a chance to fly using other radiator positions.

3. Exactly because of their rather rough nature they are more rugged.

Sorry, but I can't see your logic here.

There is still the unanswered question if the Komandogerät allowed the TA engine to overrev in dive at 110%+Wep+autopp.

The KG adjusted (beside other things) the revs by pitching the prop and so prevented from overrev.

I've edited my first post: it now includes some inflight overheat data at 260kph IAS.

Then the TA152 C is bugged, it overrevs in a dive ~2900rpm, independent from engine temp.

The H1 seems to be ok.
