Yak-9u question

[phishnut]

After playing IL2 Sturmovik and Aces High, I realized that the yak-9u in il2 has wep, but the yak in ah does not.  Which is correct? or are they both correct (different models)?  It seems like an important item to include or not since fights can be decided by speed and acceleration.  In either case, I'd just like to straighten the record.  Thanks.

it has one in AH, just does jack toejam:cool:

Agreed where is the WEP for the IL-2

[Mitsu]

B-17 had a WEP in Microprose's B-17 II...

I think it is the same thing modelled in a different way.

 The thing is, WEP in the form of "over-throttle" and "increased HP via liquid injection", "anti-detonant effect via liquid injection" are all different in concept so in the process of simplifying it into a single button/effect for a game, a lot gets lost.

 My guess is the WEP engine status for the Yak-9U in IL-2 is equivalent to the max throttled state in AH Yak-9U. In reality, I recall the Yak-9U did not have any sort of "real WEP system in the form of special devices engaged".

 In this aspect I don't think either AH or IL-2 can claim to be 'totally realistic', since they obviously depict the WEP systems as they fit for their game, not according to what it really was.

phishnut, sadly we have a Yak9U able to keep at max power rate forever, of course, this feature is enjoyed by dweebs a lot.

[phishnut]

rgr, thanks for the replies guys

" sadly we have a Yak9U able to keep at max power rate forever, of course, this feature is enjoyed by dweebs a lot."

Why wouldnt it be able to run at 100% forever?.

Daff, my first response would be Engine Overheating.

[eddiek]

All AH planes can run at 100% power without overheating, it is the ones with WEP, which increased the power to above military power, that see the gradual engine temp increase.
IIRC, the AH YAK-9U does NOT have WEP, the -9T does.
Also, IIRC, WEP is usually calculated to be like 110-115% of military power.  So no wonder a YAK can run all day with a wide open throttle without overheating.  Just like any 109/190 or other plane....................

AFAIK, AH's WEP is simplified. Take the 3 DB605A engined fighters for example: the C.205, the 109G-2 and the 109G-6. They should run at these settings:

Start and emergency: 2,800 U/min, ata 1,42, time limit: 1 Minute
Climb and combat: 2,600 U/min, ata 1,30, time limit: 30 Minutes

It sounds like IL2 is modeling the wrong Yak-9U.

The VK107 of the Yak-9U, during WWII,  did not have a WEP setting.  But shortly after WWII the VK107A was added to Yak-9U's, which added I believe water injection.  I'd have to get some books out, but thats pretty close from memory.

So it sounds like they're using the Korean war varient of the Yak.

[Daff]

I don't know that much about Yaks, but US aircraft could happily run at 100% without overheating. Planes like the P-47 could run at WEP without overheating too..the waterinjection was an antidetonant and not a coolant.
 So..unless you post documents proving that Yaks *couldnt* run at 100% without overheating, I'll claim that they didnt overheat .

* I believe you have a typo there. You meant to say Bf-109 G-10 instead of Yak9U, right?

[MANDOBLE]

Verm, WEP does not mean the usage of any special mechanism at all, just to run the engine above the military power setting, for example, just increasing the MAN over these settings. You will have more power output but engine will overheat quickly. Were the maximum settings for RPM and MAN in the case of Yak9U calibrated to keep the engine always below dangerous temperatures?
