Talk:Allison J35

Two engines?
The engine in the top and bottom images on this page do not appear to be the same design. The one at the top has separate cannular flame holders, while the one at the bottom has a single large annular area. Additionally, the lower image appears to show a two-stage turbine, although it's not clear if it's a separate spool. I'm guessing that one of these images is not the J35.

I visually checked the engine, and I mislabeled it, it is a J46-WE-8, I'll move pic no. 2. Thank you for the catch.LanceBarber (talk) 01:34, 17 January 2011 (UTC)

Origins
Provenance wise, it should probably be mentioned that Allison were licenced the design for the MetroVick F2 from which they developed the J 35 at the same time as they purchased the licence for what became the J-33 .Completeaerogeek (talk) 23:41, 11 April 2016 (UTC)


 * Sources? Because Allison didn't do the initial development of the J33 and J35 - GE did. Allison did the major production of those engines. - BilCat (talk) 23:59, 11 April 2016 (UTC)


 * Also, per Bill Gunston in World Encyclopedia of Aero Engines, 5th Edition (2006), the J35 (TG-180) was a GE development, and not based on any British engine. He mentions absolutely no connection to the Metropolitan-Vickers F.2. - BilCat (talk) 15:30, 12 April 2016 (UTC)


 * The J-35's axial-flow compressor was adapted by GE from the one designed by Eastman Jacobs at NACA. (It was intended as the compressor stage of his proposed 'ducted fan' engine which was a piston / jet hybrid like the one in the Italian Campini plane -- bit of a technological dead end.) The J-35's ring of 'combustor cans' or combustion chambers, however, was adapted from the British Whittle design. See the NASA document at Footnote 2 below the article.
