Much appreciated. I like keeping inter-wiki links up to date, and my knowledge of German is enough to do that in most cases ... but I hope you won't mind me asking for help occasionally? [[User:Morven|—Morven]] 17:32, May 16, 2005 (UTC)

== [[:commons:Image:Rolls Royce Goblin II cutaway.jpg]] ==

Hi again Stahlkocher1.

I don't know why I forgot the SAAB J21R! - I noticed the Swedish insignia but was pretty sure it wasn't a Tunnen or a Lansen.

Glad you liked the annotated [[:Image:DH Goblin annotated colour cutaway.png|Goblin diagram]]. If you can translate the captions into German and let me have them, I'll see if I can do a German version of the image.

BTW, I have adjusted your [[:Image:Saab J21R vr.jpg|SAAB J21R]] picture if you want to have a look - (I saw the Goblin's nozzle in the picture!)

:Hallo again!

:The German version of the Goblin diagram is now on Commons here: [[:Image:DH Goblin annotated colour cutaway (German).png]]

:Let me know if I've made any mistakes and I'll correct them!

== Area rule article ==

Your edits are interesting regarding Otto Frenzl and Area rule - but can you provide a source for the information. The patent image could easily be faked ('''to be clear I'm not accusing you of that''') I'm just concerned that it doesn't meet [[Wikipedia:Verifiability]]. Could you provide some links to back up the claims (preferably to copies of the German patent office documents). I only ask because a google in his name doesn't bring anything interesting up.

== Area rule and Whitcolm's work in general ==

I saw the thread on Mega's page and felt I needed to comment.

For one, the presense of the German work on the area rule is quite well known. In fact, a British duo also independantly developed it in the immediate post-war era as well. However these accounts are generally unknown, because they were unapproachable. The German efforts, in particular, were quite hand-waving on how they were supposed to work.

Whitcolm's version, on the other hand, was blindingly obvious. Let's not forget that Kucheman (IIRC, maybe Busemann) himself praised Whitcolm for producing the first clearly understandable development that designers could actually use.

To go on and suggest that Whitcolm's version was simply stolen from the German work, as you have, displays complete ignorance of the history and the technical details of how he arrived at his conclusions. This history, including the German developments and influence, it clearly outlined in NASA's own documents, which I linked to in the first versions of the article. While complaining to Mega that he shouldn't start his research on Google, I can only admonish you for doing precisely that.

But not to be stopped there you then go on to suggest that '''all''' of Whitcolm's developments were simply stolen from the Germans. Poppycock! Again, the historical record is very clear and laid out in detail in NASA's own historical documents. Developments of wingtip plates, for instance, was obvious to anyone who knew the terms "spanwise flow" and "wingtip vortex", which was basically the entire aeroengineering field. What Whitcolm did was actually put these things in a wind tunnel and test, test, test, until they figured out what ''actually'' worked as opposed to what might work. The same is true of the supercritical airfoil, which underwent the same evolution.

Here, go and read this right now: [http://history.nasa.gov/SP-4219/Chapter5.html]. As you can see it clearly credits Adolf Busemann with putting the idea in Whitcolm's head. It also clearly demonstrates that the ''particular idea'' was very different than what had led previous experimenters to the same conclusion. Also note the article clearly points out earlier German and British work, so it's not like there's some sort of cover-up going on!

:Hi Maury, thank you for your comment, but i have to comment, too. First of all the German patent on the area rule is ''not'' well known. Whitcomb was informed by Busemann about whats going on on transsonic speed. This was described in the 1944 patent. It is not stolen, but, in my oppinion, miscredited. Whitcomb was the guy who casts ideas into hardware.

:So what I found out, despite of NACA history is: The Ju 287 should be build ''area ruled'', using engines cowling to keep cross sections constant. The Ju 287 should be equipped with a transsonic low drag profile, similar to the supercritical one later invented. All german design offices should be aware of this, as they were aware of jet engines and swept wing. On the BMW design office i found sketches of aircraft using an arearuled body similar to whitcombs approach. And then: War over. And the knowledge was lost. Most interesting is, that this fundamental patent was not mentioned in german literature till now. I´ve read several books about the junkers work, but: No area rule mentioned. Even Brunolf Baade did not use it on the EF-150 any more. The question is: Why? And be carefull with statements of US officials. Some years ago they told the world that they found bio-mass-destruction weapons in Iraq. Best regards from germany -- [[User:Stahlkocher1|Stahlkocher]] 17:36, 9 January 2006 (UTC)

::I'm sorry, but you're simply wrong on this. Your only response has been to post an ever-lengthening conspiracy theory with absolutely no facts to back it up. Above you manage to confuse practically every aerodynamic term you post, leading me to believe you don't really understand any of them.

::Look, we know the Germans knew of the principle. We also know the British did too. But neither of these changes the fact that Whitcolm really did develop it on his own. PERIOD. I've seen the statements from the ''very people that were doing the work during WWII'' (Kutcheman), and they personally credit Whitcolm with his version being different and very much better. And your invented claim above that Busemann told Whitcolm about the WWII work is an insult to Busemann, who developed his "pipefitting" theory all on his own as well.

::That two people can come to the same conclusion using completely different logical processes should not be surprising. There are at least four completely different ways to develop quantum mechanics for instance, all of which were developed independantly. The motorjet concept was invented at least three times, by Coana, Camprini and NASA. In the case of the area rule I know of at least four people who developed the idea, or close to it, and have no reason to suspect they even knew of each other's work -- in fact two of these were in Germany at the same time yet I have yet to see anything to connect them.

::And what does the Ju 287 have to do with ''anything''. The aircraft clearly shows no sign of area rule effects -- if they really were using the rule they would have moved the front engines towards the rear (placing them at the nose is the absolutely ''worst'' place) and lengthened/widened the tail. The aircraft is a straight as an arrow. Furthermore your claim that the 287's wing was in any way similar to supercritical indicates you don't understand the topic at all, because it's obvious it doesn't have one. To say "it had low transonic drag, therefore it's like a supercritical wing" is identical to stating "a pin has low transonic drag, therefore it is like a supercritical wing".

::As to the patent itself, I have seen the Messerschmidt design in books dating back well over a decade, and that was in reference to earlier work. I ''believe'' it appeared in Brian Greene's works from the 1950s.

::You have yet to post a single verifiable ''fact'' to back up your suppositions. That you edited the article to insert your "theory" as if it were fact is an insult to the wikipedia.

[[Image:Junkers EF58 wind tunnel test Junkers AG.jpg|thumb|Ju EF 58]]

:::Hi Maury, there is no conspirary theory because there is no conspiracy at all. I`m just asking questions about ''knowledge flow''. I do not know anything about your background, but: The guys with this motorjet were Coanda, Campini, Khalshchevnikov (build into the [[Mikoyan-Gurevich I-250 (N)]]) and several others. It was realy common. The Ju 287 you know, this flying prototyp, was *NOT* the intended Ju 287. The only parts used from the real Ju 287 were the wings and the engines. The fuselage was from a He 177, the tail from a Ju 188 and the undercarriage from a liberator bomber. And of course where the engines on the correct position. Please refere to the patent. The upper drawing based on the intended Ju 287. I uploaded a foto showing a wind tunnel test model from the EF58-project. I guess this is the project everything starts with. And i guess you might see the narrowing body, too. btw.: Please tell me the names of this british area rule guys. Best wishes -- [[User:Stahlkocher1|Stahlkocher]] 11:19, 12 January 2006 (UTC)

== [[:Image:H19 Showing Engine.jpg]] ==

Hi Rogerd, im just working on a german articel about the [[Wright R-1300]]. I suggest that the engine in the H-19 should be a R-1300. You wrote R-1340 instead. Is this truth? Did i mess up something? -- [[User:Stahlkocher1|Stahlkocher]] 16:35, 25 June 2006 (UTC)

:You are correct. According to [http://www.wpafb.af.mil/museum/air_power/ap41.htm USAF Museum page about this aircraft] it is an Wright R-1300-3 of 700 hp. Thanks for pointing out my error. --[[User:Rogerd|rogerd]] 16:41, 25 June 2006 (UTC)

:By the way, there does not seem to be an article in the english wikipedia about the R-1300. Could you translate it to english when you are done? Thanks. --[[User:Rogerd|rogerd]] 16:50, 25 June 2006 (UTC)

== Car photos, license plate number removal and stuff ==

I am happy to hear you're OK with it :D I will be striving to edit all your pictures I will be using in the articles I edit, as I have my own pics to edit too and, as all the people here, limited amounts of time at my disposal :D Anyway, keep the pics coming! [[User:Bravada|Bravada]], [[User talk:Bravada|talk]] - 15:32, 22 August 2006 (UTC)

PS. You haven't come accross any more Simcas or Talbots, have you? A photo of the Tagora would come in very handy, as the article is to be featured in a few days and the current photo is rather so-so...

== [[:Image:Aircraft engine IP&W JT9D.jpg]] ==

Hi again Stahlkocher1.

I've done what I can with the picture - see what you think. Regards, [[User:Ian Dunster|Ian Dunster]] 14:54, 3 September 2006 (UTC)

==Felicitas Woll==

Hi yet again Stahlkocker!

When you've got a minute can you have a look at the new [[Felicitas Woll]] article on the English Wikipedia. I've just started it using [[http://babelfish.altavista.com/ Babel Fish]] for the translation from the page on the German Wikipedia [[http://de.wikipedia.org/wiki/Felicitas_Woll]] and it could do with someone who speaks German properly having a look sometime. Many thanks. Regards, [[User:Ian Dunster|Ian Dunster]] 13:56, 5 September 2006 (UTC)

::OK, thanks for taking a look. And I've found LEO - thanks! :) [[User:Ian Dunster|Ian Dunster]] 09:50, 6 September 2006 (UTC)

== Upload of images from NMUSAF ==

I see you are uploading many images from the [[National Museum of the United States Air Force]] site to commons. I think this is good to replace the existing images since many of the old images have watermarks, but I have a few suggestions:

# Use the more specific template {{tl|PD-USGov-Military-Air Force}} instead of {{tl|PD-USGov}}

# Include the actual url instead of "Source:USAF Museum"

# Consider using the commons Information template, the same way as in [[commons:Image:XC142A.jpg]]

# Consider adding the image to the commons gallery [[commons:National Museum of the United States Air Force]]
