Actually for NDW I don't, Butch.  White 1 was assembled at NDW.

If you look at Bookies list:

http://fw190.hobbyvista.com/werkn.htm

He is missing about a half a dozen FW-190 subcontractors.  Did not realize it until I started really looking closely at Bookie's page and cross-referencing the documentation.  

Interesting thing is just searching on the Internet many of these smaller and not well-known companies are still subcontracting in the Aviation industry.

Crumpp, do you know of this Wright Field document ?

Report No. F-TS-406-RE dated 10 Sept. 1945.

Do you know what the KB in Construction data of KB stands for?

Pursuit Airplane FW-190/BMW801, yes I have a copy.

No I am looking for it.  I imagine it was a small aviation company similar to Klemm-Flugzeuge GmbH (Germany).

http://www.setup-team.de/klemm-Flieger-en.htm

They manufacturered FW-190's after the owner Hans Klemm was arrested by the Gestapo and his business confiscated by the Nazi's.

What a twisted world. I belive Hartmann's first flight was in a Klemm.
There even was one here in Iceland.
Wasn't it like mere 20 hp or something?
It was very interesting to carry out the flight trials at Rechlin with the Spitfire and the Hurricane. Both types are very simple to fly compared to our aircraft, and childishly easy to take-off and land. (Werner Mölders)

Yeah they Nazi's were monsters for sure.  Hanns Klemm was a card carrying party member too.  He withdrew from the Nazi party when they arrested several of his trusted employees for being jewish.  He publically declared that the Nazi party was totally against his christian values and quit.

However as posted above they were not cleared for  general use until July '44 timeframe.  None were fitted to Bf-109G6's.

Absolutely nothing backs up this claim of yours. As usual, you keep stupidly parrotting what you would wish for..

If it came "fresh from the factory" the other possibility is Knoke has his dates mixed up.  He is only a few months off.

AHA! Poor Knoke, he mixed up the type of his aircraft, the boost of his aircraft, and the date in his diary which he recorded 1-2 day within the events...

But we have Crumpp here to help out Knoke to remember "right"! :lol


Third possibilty is these are Bf-109G6/U2's with GM-1 and Knoke has his boost systems confused.  The U2's did come out in "early '44" according to Rodeike.  After Jul '44 they were approved for MW-50 use and it was very easy to convert them.


The 4th possibilty is that a blind 190 zealot, after being confronted with the real performance specs, makes up stories to twist the truth.

Fact is, Knoke`s unit received G-5`s with ASM engines with large superchartger, boosted with MW 50. This had been confirmed at least a YEAR AGO via evidence of the Bewegungsmeldungen AND photographic evidence at butch`s board.

To qoute butch and ErichB from an old AAW discussion regarding
MW50 :

Butch :
"First use by unit in October 43 when some testing Gustavs were delivered to operational units, real deploiement in April 1944.
Keep in mind that the G-14 were designed around an MW-50 tank, add it the G-10, the K-4 and the G-6/U2 and G-6/MW50 and you get an idea of how common it was."

ErichB:

"Used in the spring of 1944 in II./JG 11 and I./JG 3, later in JG 1 and JG 300 as well as the NJG units NJGr 10 and NJG 11 until the G-14/AS and finally the G-10 were available."




Nice Power Point slide but it is FAR from original documentation.  Please produce the doc saying 595 for the 109K4 because the flight test's just DO NOT show it!


There`s a 2500x1200 pixel sized scan of an original Mtt document showing 595 kph at SL, with a low boost.
Crummp somehow cannot see it...


1.98ata according to Butch2K, a Bf-109 expert, was not approved for use until Feb' 45.

The very document he posted in regards of this notes the 1.98ata boost was forwarded to the troops, General Galland and engines were delivered at this setting.. the document notes the use of 1.98ata with recce aircraft. The DB/DC manual itself notes the use of boost in early December...
Fact is, no document come to light so far that would disprove the use of 1.98ata already in late 1944. Conclusions as opposed to this appear to be educated guesses, at best. I have yet to see evidence to the contrary. I trust the DB/DC manaul over butch, sry.

Frankly your willingness to manipulate the data severly undermines your crediability.

Funny thing coming from you.

You lied about the A-8`s introduction, you keep lying about the introduction of MW into the G-6s, you keep calling Knoke a liar because, you keep lying about the engines fitted to the A-8, you keep lying about the production and availability of the a-9s...


According to Messerschmitt then ONLY the Bf-109K4 EQUALS the FW-190A8/801S.


I`d like to see any evidence of the "A-8/801S". So far no evidence at all, and Rodeike (p270) mentions the A-8s were to receieve 801TU only. The 801TU had the same power as the 801D, in fact it was a 801d-2 only differing in armor thickness and accessories, therefore performance was also the same.

The A-8 did not receive the TS engines, according to Rodeike : "in automn 1944 started the production of the 190 A-9, which in comparision of the 190 A-8 differed only in being fitted with the BMW 801 TU/TS powerplant of increased output."

First loss of the A-9 did not came until 7th October, 1944, exact same time as the appearance of the G-10/K-4.

In Feb '45 the FW-190D9 was the 1.98ata 109K4's contemprary.

Which, as shown on the graph, was slower at all altitudes than the 109K, especially above 5.5km. At 7km, the fastest FW 190 was already 40 km/h slower than the 109K.


Same conclusion as the last thread that hashed this issue Izzy. Only the 109K4 equals the FW-190A. All other 109's are far behind the FW-190A in low altitude performance.


As shown by evidence above, the 190A-8 did not appear until April 1944, the same month as the appearance of MW boost and large superchargers on the Bf 109 G-5 and G-6.

With these, the 109G did 560/568 kph vs. 565 kph of the 190A at SL, and 665/680 kph vs. 653/621kph at altitude.

Therefore the 190A was equal in SL speed to the 109G, and massively inferior to it at ALL other altitudes, the difference being as great as 60 kph at high altitudes in the 109`s favour.


Look again, the author is talking about Umrustsatz's. Your the one who appears not to know the difference.

Nice twist again. http://www.onpoi.net/ah/pics/users/503_1104931320_g6mw50.jpg

The author talks about "G-6/R1", which he believes was a fighter bomber variant. Fact is, no such ever existed, only G-6 with Rustsatz I, which was not shown in the designation.
The author talks about "G-6/R3", which e believes was a long range fighter variant. Fact is, no such ever existed, only G-6 with Rustsatz III (droptank), which was not shown in the designation.



The author talks about "G-6/R5", which e believes was a 'heavy fighter' variant with gondola guns. Fact is, he doesn`t even have an idea what a G-6/R5 was, it was a recce variant with Rb 12.5/7.9 cameras... Gondola guns were Rustsatz VI, but again they DID not show up in the designation...

In brief, the author Crumpp is afraid to name and on whom he based his claims could not even tell apart Rustsatz kits and Rustzustand conversions, apart from mixing up gondola equipped fighters from converted fighter-recces...


Knoke's aircraft coming "fresh from the factory" makes it an umrustsatz as well. There were NO MW50 umrustsatz's produced for the G6 except a photorecon varient.
Until Jul'44 that is when the designation was changed to G14 and the existing Bf-109G6 were allowed to use MW-50. As stated before changing a U2 to a U3 was not a difficult mechanical job. Which is absolutely correct. GM-1 was introduced in "early" '44. Knoke recieved his in April '44. In Jul '44 they were allowed to convert to MW-50.


You keep parrotting the same BS like an idiot.

Yet there`s evidence of the use of MW in April 1944 on the Bf 109G in Knoke`s diary, and this was confirmed from both unit reports and photographic evidence.

Have fun with your new neighbours, you belong in the same class.

Same happened to Hugo Junkers, - one of the most brilliant designers.
He got on the wrong side of the politics somehow. It was Erhardt Milch who gave him the most trouble.

Exactly correct for the Bf-109G6/U2.  Authorization for conversion an MW 50 use did not occur until July '44.  All fuel dependent with the AS motor AFAIK.

So what it looks like is that when July '44 came and authorization to use MW 50 was approved the Luftwaffe had two sources to field 109's with MW-50.  Factory produced G14's and converted Bf-109G6/U2's.

That comes from Rodieke/Prien.  It's a fact unless Butch2k comes in and posts he has found new evidence.  

Quote
AHA! Poor Knoke, he mixed up the type of his aircraft, the boost of his aircraft, and the date in his diary which he recorded 1-2 day within the events...


Obviously you have not interviewed many pilots from the Luftwaffe.  Their technical training was not as through as you would think.  Not a particular phenomenon of the Luftwaffe but a fact for all WWII era Air Forces.  As Oscar is found of saying "Hey I just flew the damn thing, I did not fix it."  They were pilots, not mechanics or engineers.

Quote

Hardly the test flights are there for all to see, Izzy.  Even if Rodieke/Prien are wrong and MW 50 was in use on EVERY 109 in service in April of '44, the Bf-109G6 still be behind the FW-190A8 at 578kph.

Quote

Yes I saw that and it equals the FW-190A8/801S at 595kph.  The Bf-109K is NOT at low boost but at max boost Izzy.  1.98ata was not approved until Feb 44 according to the credible sources.  Fuel available.

You need to back these statements up.  I have not called Knoke a liar.  Ask anyone who has done serious research or has ever been in combat.  Mistakes happen and I only offered a plausible explanation to fit the facts.  As Butch2k says some Bf-109's were delivered to operation units FOR TESTING.  This does not represent fielding of the variant, Izzy.  If you bothered to read what I wrote you would see:

Quote
Crump says:
I am not surprised Izzy. They were constantly trying to get it to work acceptably in the 109.


Meaning Knoke received operational test aircraft.

Quote
Crumpp says:
If it came "fresh from the factory" the other possibility is Knoke has his dates mixed up. He is only a few months off.


Possible he mixed his dates up.  It was sixty years ago and you do not know exactly what was written in the diary verbatim.  It very well could have been "received planes with new boost systems today" which opens up for the third possibility I presented.

Quote
Third possibility is these are Bf-109G6/U2's with GM-1 and Knoke has his boost systems confused. The U2's did come out in "early '44" according to Rodeike. After Jul '44 they were approved for MW-50 use and it was very easy to convert them.


Facts are MW-50 was authorized until Jul '44 for the 109.

As for the BMW-801TS.  

1.  I have in hand multiple documents directing it's use from the BMW, Focke-Wulf, and the RLM.

2.  I have the test flight reports from 1943.

3.  The White 1 Foundation owns the largest collection of BMW 801's in the world, Izzy.  Out of 24 motors a large percentage are 801TS motors.

4.  Producing the BMW801TS was NOT a difficult engineering task.  It was simply new heads and a new supercharger-gearing ratio.  Simple stuff.   Simple stuff that corrected the biggest deficiencies the 801D2 had which was flow and combustion chamber efficiency.

Folks, may i point you to a little problem wiht most performance charts, including those presented in here?

Hehe, i just will do.

If one only has the charts, it's usually hard to say whether they are real flight tests or calculated data. Without the descriptive parts of a documents i would be very careful to rely on the charts alone.
But i have discovered a tendency for german documents that on charts for real flight tests, the Wk.-Nr. of the involved plane is given. (i.e. Flight test of FW190D9 Wk.-Nr. 210 002 in Hermann's "FW190D Longnose").

The charts presented in here are IMHO calculated and not flight tested.
The FW190 chart is for a performance comparison of the FW190/TA152 Series from January '45. It was also published in Hermann's Book.
The Bf109 curves are from a report calculating the possible performance of a Bf109 with JUMO213A. Those curves are given as reference points and it seem they are calculated also as no Wk.-Nr. or any hind to a Rechlin test is given.


Quote
2. I have the test flight reports from 1943


Those would be interesting, as i think Crumpp is referring here to a series of flight tests at Rechlin. There were a couple of A5s rebuild to A8/A9 status for performance measuring of these variants and testing of the higher boost pressure of 1.58/1.65ata if i remember correctly.

Interesting.
I will be posting, or mailing charts very soon, - the xls doc to present them, or rather the xls formula is being made at the moment.
I think Izzy published some flight test numbers above in the thread, or were they estimates?

Anyway, the Spitfire is rather well documented, so that data should be ok.

I will try to break down the charts within a much narrower timeframe.

So, data may be needed to make it nice, - ayway it will give a much closer look than the chart posted by Izzy....

Angus wait for Izzy to get his 109 site up and running, for that will be the MOST biased site on the internet. :)
