Friedrich-4B

Thanks tusler; some amazing photos that show it's not just flight sim pilots that can have problems landing or taking off!

Nor was the Tu-4 a straight copy of the B-29; the Soviets used metric, rather than imperial, measurements and applied their own forms of metallurgy to the Tu-4's structure. Thus, the gauges and stress requirements of the structural materials were different to the B-29s, plus the engines and armament ( 10 x 23mm cannon) were completely different.

There were in fact three B-29s that landed in Vladivostok in Soviet Russia; the first on 29 July 1944 was a B-29-5-BW 42-6256, RAMP TRAMP. The second on 11 November was (ironically) named General H.H. Arnold Special 42-6365 and the third was Ding Hao 42-6358 on 21 November 1944. All pilots and crews were interned, then allowed to 'escape" to American held territory in Iran.

Good question; it could be that the P-38 represented is a pre-P-38J-10-LO model - the earlier models had an internal armoured screen, with an external, curved plexiglass windscreen. Apparently this configuration created distortion, which is possibly replicated in the gunsight view.

No sign of the Jug yet; here are some more details to keep the appetite whetted: From Detail & Scale Vol 54:

And Douglas Bader, "Johnnie" Johnson, et al, of the Tangmere Wing. A station steeped in a rich history. http://www.tangmerepilots.co.uk/history.htm

Added; a report on the design of carburettor air scoops and their effect on fuel-air metering; although not directly related to exhaust thrust, it shows the importance of the incoming airflow to the engine's overall performance:

What a shame; looks like the only people who will ever see photos of White 1 are ex- Foundation members. :no_sad: Ah well, here's one at least, dated August 2010 - part of a portfolio on Wikipedia: Actually, there are several photos from 2010, although the photo of the purported engine definitely isn't a BMW 801 https://commons.wikimedia.org/wiki/Category:Focke-Wulf_Fw_190_museum_aircraft

There don't seem to be many images of White 1 on the internet, so it would be good to see some photos of the project progressing in its early stages. AFAIK, the project is still underway and now under the Collings Foundation after the White 1 Foundation folded http://www.warbirdsnews.com/warbirds-news/focke-wulf-fw-190f-8-restoration-underway.html

+1: fantastic artwork and background research! http://www.332ndfg.org/ http://tuskegeeairmennationalmuseum.org/history/who-were-they https://www.tumblr.com/search/332nd%20fighter%20group http://www.redtail.org/the-mustang/

Some D-30 color schemes (from Republic P-47 Thunderbolt "Bubbletop" ):

And none of the Spitfire IX reports. Thus of no use at all, unless the accuracy of the transcripts can be compared with the originals. Got it in one. :thumbup: Spitfire II is also a good read, because it's full of absorbing stories from not only fighter pilots, but PR pilots as well. Plus, it's going for a low price here, with postage = US$4.99. Recommended.

I don't think Crumpp actually read what I wrote: :dunno: Of course the VVS would have known the differences between a Merlin 61 or 63 and the slightly detuned Merlin 66s they were getting in their L.F Mk IXs. :music_whistling:

Not that Supermarine were responsible for the design of the exhaust stubs :smilewink: But, somehow, the British muddled through, in spite of their poor design philosophies and slow, badly designed fighters. :music_whistling:

Better still, they can be downloaded from here: http://forums.eagle.ru/showpost.php?p=2313908&postcount=378 As Crumpp has pointed out elsewhere, engines could be tuned for different applications http://forums.eagle.ru/showpost.php?p=2347617&postcount=76; the Merlin 66 was a derivative of the redesigned, reinforced Merlin 63, so it looks as though the British were sending slightly detuned versions of the Merlin to Russia - possibly swapping slightly less power for better reliability under extreme conditions. Very interesting, and thanks for the information SKR. Dilip Sarkar's book on Johnnie Johnson is a really good read, complementing and supplementing Johnson's autobiography extremely well.

Here is a 1943 NACA report on exhaust back pressures:

Thanks for your offer SKR, I would be interested in seeing the test reports. I will send a Private Message to you. :thumbup: While I don't yet have the hard copy of Spitfire IX & XVI Engineered, I do have Robert Bracken's Spitfire II - The Canadians, Monty Berger and Brian Street's Invasion Without Tears and Dilip Sarker's biography of Johnnie Johnson - all of the Canadian RAF units did a fantastic job and deserve all the credit they can get. :beer:

Seconded and thirded! The A-26 did excellent work over Europe in some tough conditions; same again over Korea and Vietnam.

No apology needed! Your English is far better than my Russian. :v: There is not a lot of information on +25 lbs boost in "Spitfire the History" except to state that the modification was known as "Basta". For some excellent information on Spitfire tests, have a look at this website: http://www.spitfireperformance.com/spittest.html for the Mk IX tests, see: http://www.spitfireperformance.com/spitfire-IX.html Here is a downloadable pdf of +25lbs boost tests made by Rolls-Royce in October 1943: http://www.spitfireperformance.com/JL165-Rolls-Royce.pdf and here is another set of tests: http://www.spitfireperformance.com/ma648.html **************** At least 2 Spitfire Mk VIIIs, JF275 and JG204, were tested using 100/150 grade fuel and +25lbs boost. JG204 is mentioned in paragraph 4.43 of the A&AEE trials of Spitfire IX JL165 (below) http://www.spitfireperformance.com/jl165.html Spitfire L.F Mk VIII JF275 test results from Morgan & Shacklady (NB: should read 150 octane fuel): As far as I know, no Spitfire VIII used +25lbs boost on operational service (the Spitfire VIII was almost always used in the Mediterranean/Italian theatres and by the RAAF in the Pacific, where 100/150 grade fuel was not used). http://www.spitfireperformance.com/spitfire-VIII.html For information on the performances of many other WW 2 aircraft: http://www.wwiiaircraftperformance.org/ Hope this is of some help.

+ 100%, and glad to have brought it to your attention. I'm hoping to get my hands on the hard copy, but the postage rates are a pain and my spending priorities are elsewhere for now. No, only the paper; is there any information in particular you're wanting?

Lemme see, the reason for this poll was... And the only air force operating the B-25 and fitting in with the Normandy map, was? Something rhyming with 2nd Tactical Air Force. :music_whistling: Not that anyone mentioned fuel...:smilewink: However, now that the subject of fuel has been raised, there will be those mischievous diehards who'll be wanting the B-25s of 2 TAF to use 100/130 grade, rather than 100/130 octane. Anyway, those who don't care about fuel threads can always opt to stay away from and/or ignore them. :music_whistling: :smilewink: :thumbup:

Just because the B-25 was only operated by the RAF doesn't make it irrelevant to a post-D-Day Northern European scenario; as I've said earlier, it participated in some of the more interesting ops undertaken by 2 TAF and it deserves to be represented. That's not just my opinion.

Nobody said that the B-26 didn't serve in the USAAF in large numbers over Europe - what was mentioned is that the RAF operated B-25s over Europe as well. But, seeing as the subject has been raised, in fact a total of 502 B-26s were given to the RAF and all served in Africa and the Mediterranean vs 910 RAF B-25s that served over France and northern Europe - so not exactly "almost as many B-26s". As it is, in this poll the present score is B-25 = 28.23% vs B-26 13.71% :smilewink:

Although Crumpp might not be interested, the majority of them served in 2 TAF, doing great service until war's end. One of the more interesting operations undertaken by 2 TAF Mitchells, in conjunction with Typhoons, was the destruction of Panzer Group West's HQ on 10 June 1944: (From Shores and Thomas 2 TAF Vol 1)

Yep, the B-26 is one of my favourites as well; still, the thought of puttering around in a Po-2, waking up the Yankees with small bombs has a certain appeal.
