Mounting motor on a Fairfax B-25 bomber, at North American Aviation, Inc., plant in Inglewood

[edit]

I reverted your edit to File:Mounting motor on a Fairfax B-25 bomber, at North American Aviation, Inc., plant in Inglewood, Calif.jpg to the documented original description. When you change information, please add your source in the edit summary. You stated that the engine is Wright Cyclone, I am quite sure this model was fitted with a Wright Whirlwind. But since neither of us has a source, let's prevent spreading misinformation, and stick to the documented description. Jan Arkesteijn (talk) 10:52, 5 September 2010 (UTC)[reply]

Hi, well I certainly disagree. The description is rather inconclusive, as there is no "Fairfax B-25 bomber". B-25 "Mitchell" bombers were produced at Ingelwood and in Fairfax, Kansas. Either way being powered by two R-2600 Cyclone engines with 14 cylinders arranged in two rows. Each produced some 1.800 hp. The Whirlwind had 800 hp max (and only 8 cylinders) which would have never gotten a B-25 bomber in the air. All photos out of this series show B-25 "Mitchells". Therefore I still see these engines as R-2600. Also note the B-25 engine nancelles. Can you name any aircraft having such nancelles and a Whirlwind engine? Thanks in advance Cobatfor (talk) 11:04, 5 September 2010 (UTC)[reply]
You have to help me there, since English is not my native language. What are nancelles? Jan Arkesteijn (talk) 11:24, 5 September 2010 (UTC)[reply]
Since you know much about this, apparently, and the description of the original image is indeed inconclusive I can only refer to http://loc.gov/pictures/resource/fsa.8b04698/ which shows a black/white image of the situation, saying it is a Wright Whirlwind. Jan Arkesteijn (talk) 11:38, 5 September 2010 (UTC)[reply]
Well, the nancelles are the things in which the motor is mounted. To the LoC description: It CLEARLY says, that these are B-25 bombers with 1.700 hp motors. As I said, the Whirlwind produced only 800 hp and was never used on a B-25. All B-25s were powered by R-2600s. Also, remember that the description is the original "propaganda" description from 1942 - and not always correct (Here it says that this photo was taken in Kansas, the other one says it was taken in Inglewood. Also: a Fairfax B-25 does not exist). Can you give any proof of a Whirlwind engine mounted on a B-25? Also, the photo shows two rows of cylinders on the engine, wheras the Whirlwind had only one.

Of course I can not give proof, but in Wikimedia/pedia it is all about sources and documentation. Original research is out of the question. So I gave you sources. I looked at http://en.wikipedia.org/wiki/Wright_Whirlwind and you are right, the Whirlwind does not deliver this hp in a single engine, but the models R-1510 and R-1670 were 14-cylinder twin-row radial engines. Why don't you start a discussion on the talkpage of the image. Oke, now for my own bit of original research. This engine shows a oval shaped housing around the central shaft. The Cyclones in the Category:Wright R-1820 all have cone shaped housings. Can you explain that? Jan Arkesteijn (talk) 12:09, 5 September 2010 (UTC)[reply]
By the way, File:Woman working on an airplane motor at North American Aviation, Inc., plant in Calif.jpg shows a woman working on engines. In the bottom left a specification plate is visible. I looked at it in detail and it says it is a Cyclone 14, but the housing around the shaft is, as I said before, cone shaped. It would be nice if we could find an image of the matter in question where the plate would be readable. Jan Arkesteijn (talk) 12:18, 5 September 2010 (UTC)[reply]
The "Cylcone 14" was the R-2600, see [1]. Also the NAA Fairfax and Inglewood plants produced the B-25 File:Assembling B-25 bombers at North American Aviation, Kansas City, Kansas.jpg, which had R-2600s, and only R-2600. See B-25 versions here [2] or here [3]. Cobatfor (talk) 12:29, 5 September 2010 (UTC)[reply]
I have tried to read the specification plate in the photograph, but I can't detect what it says. The only thing I see is that the name on the plate is to short to read Whirlwind, and that the name is followed by probably a two digit number. It is therefore possible that it says Cyclone 14. The question remains why the shape of the housing of the propeller shaft differs from the other pictures. Jan Arkesteijn (talk) 17:34, 5 September 2010 (UTC)[reply]
Can't read it either, not even as a 190MB tif-file. But you still have not accepted that B-25s were only powered by R-2600s? Haven't you? Cheers Cobatfor (talk) 21:45, 5 September 2010 (UTC)[reply]
No, I have accepted that in general. But shape of the propeller shaft housing bothers me. Jan Arkesteijn (talk) 22:33, 5 September 2010 (UTC)[reply]
I re-inserted your edit, because there is no reasonable doubt about it, I think. Is it ok if I copy this discussion to the talkpage? Jan Arkesteijn (talk) 09:26, 6 September 2010 (UTC)[reply]
Sure, go ahead. I also added the original description. Cobatfor (talk) 14:56, 6 September 2010 (UTC)[reply]
