-Heinz lange:"The FW-190A could do just about as well"
No sustained multiple 360° turns on the deck, or described as long sustained horizontal turns at low/medium altitudes... Again, find an account similar to the Johnny Johnson account... The Spitfire CAN greatly out-turn the FW-190A in short unsustained turns, at altitudes above 20-21 000 ft or at speeds above 250 MPH...
In your second example the FW-190A "dived down" to attack... NOT low-speed...
For all I know all these combats could have occurred above 20 000 ft... One of them is at 27 000 ft if I remember well, as it is not the first time I see these...

-It is the FW-190A's HANDLING that deteriorates in a peculiar way above 21 000 ft, and not the BMW 801 engine performance that was peculiar,

He chose for this the longest chord variant of 3 different types of ailerons, and extended that chord further by using field-installed "hinge spacers", creating a gap at the aileron hinge, which improved the low-speed turn performance even further. He also described the broad wood prop as being another significant advantage in low speed sustained turning with the throttle reduced.

So far it is YOU who hasn't addressed directly any of the evaluations I presented, and I have presented far more than you...
The last quote above doesn't square well with your contention that a FOUR minutes turn fight of Tempests with FW-190As would have ended worse with Me-109Gs...
Four minutes by the way means around 10-12 consecutive 360° turns: See, these fights are not that hard to find... Try now and duplicate that on a computer game based on current "theory"...
I don't like saying this but if you have read as much as you seem to by Closterman then you have either forgotten or if you haven't forgotten then you are being as Churchil once said, being economical with the truth. He flew both extensively, you may also want to read up on Beumount a pilot who knew the Tempest best.The Tempest is not known for its agility? Never heard of anything along those lines,
but why don't you check the Britsh RAE evaluation of the Me-109G vs the P-51B WITH FULL DROP TANKS? "The P-51B easily out turns the Me-109G even with full drop tanks." Against the FW-190A the same P-51B WITHOUT DROP TANKS: "there is little to choose between them" (Source: Le Fana de L'aviation.)
Again, the Me-109G performance in sustained turns benefited from downthrottling: According to Fin Me-109G ace Karhila, the optimal speed to sustain turns (downthrottled) in the Me-109G-6 was... All the way down to 160 MPH (250 km/h)!
Against the Me-109G the Tempest was found to be superior turning to the Messeschmitt fighter, but about equal to the FW-190A, which kind of fits well with the 4 minutes 12 X 360° turns example provided by Clostermann, wouldn't you say?
Quote, Glider: "As for the P47 I have never said that it could turn inside the Me 109."
My favourite quote all thread! Hohooo... Have you read a SINGLE ONE of the 600 combat accounts on the P-47 "encounter reports" I linked?
P-47 Encounter Reports
Maybe you have never said that because you know nothing of the relative turn performance of the P-47D vs the Me-109G?

Russian Front Line report is interesting, the J Johnson I covered in my previous posting and you misquoting of the third has been noted.
I totally agree however this tactic applies to any aircraft and is my best estimate as to what happened in the combat with JJ.
Oh yes, I have and believe that at slow speed the 109 would have a good advantage over the P47
[/I].
-Explain "your misquote of the third"....?!?
-I find it funny you question the 80% figure not having read the full collection of reports which you know I have... I include in "turning combat" anything involving a likely one full turn... Also note the bottom of the P-51 column is 100% turning combat with quotes next to them, including two 15 minutes long ones to one side (vs Me-109G of course): 40-45 consecutive 360°s...

-IF you accept that 160 MPH is the best sustained turn speed for a Me-109G-6, then by definition YOU JUST ACCEPTED THAT DOWNTHROTTLING IS NECESSARY FOR THE OPTIMUM SUSTAINED TURN PERFORMANCE: This is BARELY 60 MPH above stall speed: Do you really think the Me-109G can turn hard enough at these low speeds to lose 140 MPH of forward speed at FULL POWER?!? Karhila's quote of this speed is in the context of describing downthrottling... Here's the quote:

Note the 140 MPH speed at the end of the first one, after 3 consecutive spiral climb 360°s...
So am I to understand you accept that the Me-109G needs to be downthrottled in order to survive in sustained turning combat? That IS what an "optimal" turn speed of 60 MPH above stall entails...
If downthrottling is accepted for reaching the optimal sustained turn performance, we might be getting somewhere...

Karhila's quote of this speed is in the context of describing downthrottling... Here's the quote:
Actually you are comparing apples with oranges - or more explicitly banked turn with straight and level flight, full power versus low power conditions.
The stall speed for the 109 (and 51 and F4U and Fw 190, etc, etc.) is much higher in max G, banked turn at full power. If you 'downthrottle' as you approach this speed you can NOT maintain your altitude - you will enter a descending spiral.
"I learned to fly with the "Cannon-Mersu" (MT-461). I found that when fighter pilots got in a battle, they usually applied full power and then began to turn. In the same situation I used to decrease power, and with lower speed was able to turn equally well.
This is a manuever tactic which has nothing to do with maximum turn rate. As long as you have more thrust available than required for the bank angle and speed envelope you are in, you can decrease the radius but you won't improve the turn rate. Furthermore, aerodynamically speaking he will not achieve his max turn rate by decreasing power
I shot down at least one Mustang (on 4th July 1944) in turning fight. I was hanging behind one [2-4 full 360° circles in another interview about the same dogfight], but I could not get enough deflection. Then the pilot made an error: he pulled too much, and stalling, had to loosen his turn. That gave me the chance of getting deflection and shooting him down. It was not impossible to dogfight flying a three-cannon Messerschmitt."
This is simply two equal a/c in a turning manuever, with one making a mistake trying to out turn the other. What you do not know from this account is a.) the airspeed, b.) the applied power, c.) climbing, sinking or level flight,d.) the relative flying skills, e.) the condition of the airframe and powerplant, etc
In other words, an anecdotal account written by the winner.
" When the enemy decreased power, I used to throttle back even more. In a high speed the turning radius is wider, using less speed I was able to out-turn him having a shorter turning radius. Then you got the deflection, unless the adversary did not spot me in time and for example banked below me. 250kmh seemed to be the optimal speed."

How about another quote from Luftwaffe test pilot Lerche? "One thing was certain: the strong points of the Thunderbolt did not lie in dogfighting at heights under 6,000 m (19,700 ft). It was excellent in higher altitudes, in diving attacks and flying with maximum boost". Page 113 of "Luftwaffe Test Pilot" by Hans-Werner Lerche.
The tested P-47D-10, former YF-U 'Beetle', was lost when it ran out of fuel on Nvember 7, 1943. I know that this particular ship (42-22490) from the 355th FG had less than 60 hours on the airframe and engine.
In fact, I would go further: Show me the Me-109G surviving sustained turning combat with ANYTHING other than a Merlin P-51 that does not downthrottle: I would be very curious to see a Me-109G win against anything in prolonged sustained turns if the Me-109G pilot does not downthrottle in sustained turns...
Again, the Me-109G could carve a tighter initial turn than even what a FW-190A could, but was extremely "draggy" while sustaining prolonged turning for some reason...
The Me 109G was 'draggy' - period. The only reason a Mustang could turn with (not better - just near equal) the 109 is that the 109G had about 50% more flat plate drag to offset the advantage the 109 had with lower wing loading and leading edge slats for nearly 30% more CLmax. The Mustang did not bleed energy as fast as any other fighter it flew against.
Oseau demise witness, Quote: "Each turn became tighter, and his Bf-109G-6AS lost more speed in the turns than his P-51D adversaries. He was probably shot down near the ground. Many times I had told Oseau the FW-190A was better than the Me-109G, but being an old Me-109 pilot he preferred it..." "Defence of the Reich" Jagdwaffe series...
So am I to understand you accept that the Me-109G needs to be downthrottled in order to survive in sustained turning combat? That IS what an "optimal" turn speed of 60 MPH above stall entails...
No, it doesn't.
As the bank angle increases, the AoA increases to provide an increase to CL (and necessary Lift vector to offset weight). The limit to sustained flight at constant altitude and velocity is when CL reaches CLmax. This limit (high G/steep bank angle) is at a significantly higher speed than a level flight stall.
If downthrottling is accepted for reaching the optimal sustained turn performance, we might be getting somewhere...
You must have a mouse in your pocket - because you aren't convincing anybody regarding anything - other than you do not know the slightest aspect of aerodynamics or the mechanics of flight.
Full quote
I first flew the Fw 190 on 8 November 1942 at Vyazama in the Soviet Union. I was absolutely thrilled. I flew every fighter version of it employed on the Eastern Front. Because of its smaller fuselage, visibility was somewhat better out of the Bf 109. I believe the Fw 190 was more manoeuvrable than the Messerschmitt — although the latter could make a tighter horizontal turn, if you master the Fw 190 you could pull a lot of Gs [g force] and do just about as well.
Since when does one turn equal sustained turning combat? However if you are so confident then pick an example, the offer is still open, despite you changing the basis.

I have asked for a link to that quote I notice that you have not supplied one
"Ofw Leo Suchmacher of II/JG 1 recalled: "Many times I had told Oseau the FW-190A was better than the Bf-109.... Oseau was attacked by P-51s which forced it into a turning dogfight. Each turn became tighter, and the Bf-109 (Me-109G-6AS) slowed down, more so than his adversaries. Oseau was probably shot down near the ground."
Well slowing down doesn't appear to have been much help now does it?
Well I "notice" too there is no link to your last question: The quote by the Germans of KG 200's test is from a book: "On Special Missions. KG 200". Find the book and look it up...
The quote in full, from German testers, is: "The P-47D out-turns our Bf-109G"
What was the German comment in that same book, about the P-51B, immediately after that? No mention of the P-51B out-turning the Me-109G, but only that its stall was very dangerous and had killed one of the German pilots...
This you have stated a number of times and the only evidence that you can provide is one repeat one combat report.I will re-iterate here I never denied the Me-109G or Spitfire could cut a tighter unsustained turn RADIUS than a FW-190A, and this likely at any speed: In sustained turns past a 1 full 360° however, it is another matter and neither the Spitfire or the Me-109G had much hope against a FW-190A...
Re the Me109 being out turned by the P47 I find interesting but believable if the tests were undertaken at hig speed as the 109 controls became very heavy at high speed. Which is why the details of the test need to be explored. As I have already said if those tests ere undertaken at slower speeds then I would need to change my mind. There is nothing wrong in that approach.The Me-109G was confirmed by the Germans themselves as slower-turning than a P-47D, and admittedly the early P-47D Razorbacks with needle-tip props could match in left turns late 1943 FW-190As (FW-190A-6 most likely).
The P-47D in late 1944 with Paddle-blade prop was easily defeated in turns by later FW-190A-8s.
The P-47D Razorback with needle prop in left turns could out sustain turn the Merlin P-51. It could very likely out sustain turn the Spifire Mk V and likely the Mk IX as well (which was near identical to the Mk V in turns)...
You have this fixation about sustained turns which were so rare its of no importance and even so you have nothing to suport this statement except your one combat report.Note that none of this is related to the minimum unsustained radius: I mean the SUSTAINED horizontal turning...
Again, the 160 MPH "optimal turn speed" quoted by Karhila is quoted in the context of downthrottling. Here is again the quote:
Where on earth did you get this idea that a turn radius is unsustained in a flight test and something else in combat? I do hope you can support this statement.-Again I would simply note here that, despite the use of "radius" (which I said myself was usually a reference to unsustained turns), in WWII this term of radius was more specific in its use in flight test reports: In test reports "radius" is almost always a reference to unsustained turns. However, when WWII fighter pilots speak, the word is more indifferently used. What is important then is that when WWII fighter pilots say "out-turned", the time it takes to pepper a target long enough to bring it down (with the average 2% hit rate) means that "out-turned" for fighter pilots is almost always a reference to sustained turns, even when the term "radius" is used...
Sustained turns have a radius too... But if you want to continue being in the dark be my guest...
I noticed that whenever I bring material that demolishes the preconceived notions you have, you always dismiss it as "interesting"...
For instance the entire "Russian experience" evaluation... It is very "interesting" isn't it?
I still haven't heard you say what you think they mean by: "The FW-190A inevitably offers turning combat at a minimum speed"...
It would be very "interesting" to hear what you have to say about it...
Stay tuned for my next post: There is a few more "interesting" quotes and links that surfaced recently that should be enlightening...
Gaston
GAston: George Beurling was a Canadian, who flew with the British, and he was ok at math. He used trig to compute deflection shots during combat..... pretty good for a Brit/Canadian boy..... you lose that bet, buckwheat.
The Hurricane did not have a lower wingloading than the Spitfire.
Hurricane Mk1 and Spitfire Mk1 had identical wing loading of 25 lbs/sq ft.
Hurricane MkIIc was 29.8lbs, Spit Vb was 27 lbs.
Hurricane MkIV, 31 lbs/sq ft, Spit FMk IX, 30 lbs/sq foot.
IF as you say the FW190's in late 41 early 42 were shooting down MK V Spitfires by 'sustained turning', (rather than by using their 50 mph speed advantage like everyone else in the world has been led to believe), then how did the emergence of the MK IX Spitifre (Mk V airframe, Merlin 61 or better engine) change that? The only difference between the Mk V and the Mk IX is the more powerful engine which gave the Mk IX comparable climb and speed to the FW190. How did that extra horsepower (rather than de-rating) tip the balance in favor of the Spitfire against the FW190?
While being outnumbered. What a surprising outcome.
Actually he was attacked by P-38s of the 428th Fighter Squadron (474th FG, 9th AF) and the fight is said to have lasted 20 minutes.
Walter Oesau - Wikipedia, the free encyclopedia
Oesau was chased by 1st Lt. James Leslie Doyle, 1st Lt. Wilbur L. Jarvis III and 1st Lt. James C. Austin, of the 428th Fighter Squadron (474th FG, 9th AF). All three were experienced pilots and chased Oesau from 28,000 feet to tree-top level. In the ensuing 20 minute dogfight, Oesau defended skillfully, though his aircraft was damaged by gunfire. While attempting an emergency landing, his Gustav received a final burst of fire in the cockpit area and crashed into the ground 6 miles south west of St. Vith. His body was thrown clear of the aircraft some yards away.
