On a brighter side of things, this is turning out to be one of them ol' fashioned Luftwhiner threads.

...and God knows we've not had one of those in a long, long time. Ahhhhhhh, the nostalgia...



Sorry, we're all just ker-rap, of dishonorable character and intent and of no redeeming qualities whatsoever. What did you expect? We're not looking for a leg-down, exactly.

     I think the right-angle stress-riser of the prop blade/spinner junction, from the leverage created by the shifting prop center of thrust described by PJ_Godzilla, is the overlooked factor here. It is not a small burden because of that right-angle leverage...
  

Whoa, careful here. What  I described was the blade alpha change as you rotate the disk in a/c pitch. Admittedly, this causes a reaction torque - as does the change in the rotational velocity vector (tau = I*omega, anyone?) but I never said it was a "heavy burden". I sadi you'd have to test (or at least do some clacs) to figure out the relative scale. Further, this reaction torque is just that - a torque about the pitch axis opposite the a/c pitch. Why would it be any more or less significant on the FW? Clearly, by your own argument, the Spit can do the same thing. Or, are you just stating that the Luftwaffe taught partial-throttle use of the 190 and that our partial-throttle AH turnrate is off?

Inquiring minds want to know.
All that said, I'm enjoying this thread.

just curious, what should we be discussing in a thread titled 190A5 vs 190A8 ...

???

(_@_)s


It's Spring time.  The weather is warm enough for the lederhosen to come out and the Luftwhiner threads soon follow.

"i think hitech has concerns that go far beyond many of the things we are discussing here, he addresses things or doesn't for his own reasons, most of which (in my experience with online interactions) he keeps to himself."

Obviously you were wrong Thor as HT has time to chime in to say all this pondering is just crap. It took just 17 pages, next time it will take 18 pages...  :rofl

Besides, I don't think Crumpp "left", I understood he was thrown out. Tell me if I'm wrong.

i don't think you have any idea about what i was talking about ...

of course most of our interactions (HT and i) are on other boards so you may not be seeing the whole picture
 and that is not your fault ...

i'm sure anyone who is not here is not here of their own accord as sunglasses are easy to put on ...

he is probably just too busy with that 190 to bother with things here ...

    -Yes it precisely the partial throttle modeling that is off, as is the notion that the best sustained turn rate is reached at full power, and at speeds above 220 MPH, when Fin ace Karhila found his preferred sustained turn speed at 160 MPH on the Me-109G-6... This might not mean the superior turn rate, but at least equal to the best possible sustained turn rate, with the further sight lead offered by a smaller radius in itself...

    As for where is the FW-190A-8 Western Ace, who described the three different types of ailerons the FW-190A had, and the one he chose (longest chord for the optimum performance at the lowest possible speed, at the expense of high-speed aileron performance), with the addition of field-made spacers to increase chord further and talking generally about how the FW-190A-8 was ALL about downthrottled flaps-out low-speed horizontal turn performance, catching the stall on the ailerons, "I feared no other fighter in my FW-190A-8".

    His opinions were posted here through a close relative who interviewed him on the phone, but he did not wish to to be identified apparently... It was obvious from the mass of intricate, and unexpected, knowledge he had that he was not a "poseur"... And I later found all Soviet evaluations painted the same picture, as did most Western pilots to the perpetual bafflement of simmers everywhere ever since...

 I have spent several hours searching the AH forums for this thread which dates back to around 2003-2005, but I am pretty sure it was deleted as I never could find it...

  I call on whoever can solve the problem among the administrators of this board to find this thread and post it here, as I find it highly strange that such an important thread full of unexpected information, from a very credible-sounding source, has been deleted and is not in anyone's memory around here: Just how many ORIGINAL first-hand accounts of FW-190A combat does surface on these board?

  I'm sure SOMEONE aroud here remembers this thread, it was quite long, and I think it is not beyond possibility that it could be found, assuming we are not dealing with a bit of bad will here... I have spent over 8 hours searching for it on this site and came up with nada, so unless someone is afraid of confronting the real deal, I would suggest it should be brought up minus the vitriol that caused to be deleted...

  I REALLY doubt I am the only one around here to remember it...

If I prove mathematically, that you are wrong, will you believe me?

i think that would be off the point, as we all have read of pilots not at their optimum turn rate reducing throttle or dropping flaps to close their turn in order to achieve an angle, or evade an attacker ...

so proving your point mathematically may be possible, but it is pointless in this part of this discussion since it is about improving your turn rate/radius not where the best rate/radius is power speed alt etc. wise.

i think.

And if you are below best, you need to add power or dive for more speed.... what's your point?

it was pretty clear ...

the one doesn't necessarily have everything to do with the other, as your example shows as well.

reducing throttle or dropping flaps to "close" their turn = reducing turn radius.  Once established, best sustained turn rate is achieved at maximum power, at least with the aircraft in this game.  If you guys want to have an intelligent conversation about this stuff, you have to use more precise language.

I tried making that point probably 5 pages ago. Apparently I was ignored.
