"If you’ve been to my site, you’ve seen “the offical performance claims of the RAF for the Spit9”
Thx, after reading through your intro page i´d like to see the real documents. Because reading through the tests i always get the impresseion that every machine was specially prepared and assembled for the test instead of coming right out of the factory.
"I have the same F4 numbers from the Kennblatt, however as you’ve noticed they don’t add up and are unreliable. I couldn’t use them. "
You don´t use them because they are too good for you and don´t fit into your crusade against the 109...
Yes there are some typos, the guy who translated the original should wear glasses, he has huge problems to distinguish a 0 and a 6 (the original document must have been in very poor condition). This way he typed 606 instead of 660 and, very funny, 16km altitude for the continious power number. Over 900PS in 16km altitude, wow, now THAT´s a high altitude engine, right? (it´s 10km of course).
Then there´s a mistake by the germans, they used the values from the F1/F2 Kennblatt (for example 495km/h combat power) but listed them for the meanwhile reduced power settings. Speeds would be a bit lower of course.
Those are the errors i can spot currently, otherwise it seems to be ok.
And this means that with combat power the 109F4 is faster than your spit15 @15lb, and with emergency power it would have been pretty equal up to 22k to your Spit LF (which is the optimized variant for speed with the clipped wings). What, on the other hand, would mean it was faster than the standard Spit9 HF @18lb boost.
Where can i find the RAE report? Do you have the docs? I haven´t seen the 601E manual too so far (You´re sure it is a E and not the N) May i see it? Thank you.
In any case you quote the report 110 you should always mention estimated performances Thank you. Just a matter of fairness.
Speaking about the "german" Spit 5 you should also mention the maximum speed the germans reached with the "original" Spit5: only 460km/h in combat mode. When your spit
Speaking about overboosted engines don´t forget the "überlasteten" Motoren of the Mossie chasers on german side. But let´s stay with the F and 9.
"You guys seem to forget that the Spits had their wings strengthened and ailerons shortened "
Sorry, but shortening ailerons may lighten them, logically, but reduce their effect. More wing area is now working "against" the rolling, and less in favour.
109F and standard Spit shared the same handicap, the ailerons did not reach to the wing tips. This outer area, which moves fastest ina roll logically, is working nicely against a roll movement. The Spit is handicaped even more due to the significantly higher wingspan.
