109 e4 performance

[TomcatViP]

What a crazy little talk we've got there. I'm waiting for such arguments when it will come to talk abt any Spits Mk max speed and xxlbish boost.

With many respects, if the 109E max speed was stated as 500 that is that the vast majority of planes delivered did reach that value with only a few being in the minus 5% range.
In other word, once contracted Bf (Me) had much more interest in targeting the 500 +5% to get the necessary nbr of planes out of production line accepted than saying its engineer : Ok guys the min value is that so let's cross our arm, raise our boots on the desk and let the min value be a standard.

Does it happends that a plane does not meet the contracted spec ? .... Yeah and in deep trouble is the manufacturer. Even in an all out war (I am thinking at the Me410 that was rubish in term of manufacturing standards).

SO let's be raisonable and assume without too much headaches: 95% were in 500ish and 5 % were 475+ish. Some rare birds will do more evidently.

Storm had that in mind (I am not a stat specialist) but I think that he seems to be on the right track. Gaussian is how it shld be

And by the way if the spit was in 500- range any one here with e sense of history shld understand that the 109 has to be in 500+. Just look at the racing examples made out of both those plane : Spit : 630/650 / 109 700- (not the 209 - don't mistake me)

By the way there is not a single serious history book that will give you a value significantly under 500 for the deck max speed of the 109. Why shld we hve this here ?!!!

This is boring

I hope so

Statement is not good enough, especially when it comes from the manufacturer. Ok I see your opinion, now we need to get some evidence and exatc numbers. So, again - what engine, what settings etc?

Of course, but what settings, what engine, what about the other rated power? This is not a history book with a figure, this is a flight sim.

Don't read it then dude

Well I am only reading the illustrations when I am reading history .... but I hve to say that the technicals details in red little riding hood were a bit tricky for me ...

According to the discussion here http://forum.12oclockhigh.net/showthread.php?t=5585

the DB601Aa was used for the fighter-bomber 109's, Do215 and so.

That's not really what is being said in that forum at all Did you have a look at the info I've sent you via PM?

One thing i have tested, FTH for the Bf109 in the sim is 4.500m, so it must be the DB601A1 modeled.

It's the A1. There's an Aa in the game as well but no aircraft use it currently. Both the Aa and A1 have 1020 PS listed as their "maximal power" ratings, whatever that means.

RL data I've seen says that at 2400 RPM at FTH the BD601A will make 1020 PS but the Aa should be higher, and both should be much higher at sea level. Possibly this is the reason.
