Naming

Should I keep the article under the Pratt & Whitney designation of JT3C, or would it be better to move it to the USAF designation of J57 (and similarly for JT4A/J75 and JT3D/TF33)? GCarty 19:13, 14 July 2005 (UTC)

Keep here, redirect others, use piped link to include both in listings such as that at Pratt and Whitney. Gene Nygaard 19:42, 14 July 2005 (UTC)

Could we change the page title to J57/JT3C though?

First 10k Engine?

Anyone have a source for this claim? The Sapphire and Avon were running around the same point in time, the Sapphire in '49 IIRC. Maury 14:50, 27 November 2005 (UTC)

Good question. This claim came from the USAF musem website IIRC. Collier Trophy sites do not give the specifics of the achievement. I'll change it to first US engine in the 10k class. Good catch! Emt147 19:09, 27 November 2005 (UTC)

XT45/XT57

The XT45 evolved into the J57, the XT57 evolved into the J75 AVKent882 (talk) 01:40, 16 April 2010 (UTC)

Reliable sources? Anyway, since the T57 is a derivitive of the J57, does it really make much difference which exact model the J75 is descended from since both are covered on this page? (Assuming you're correct.) - BilCat (talk) 04:11, 16 April 2010 (UTC)

According to The Engines of Pratt & Whitney: A Technical History by Jack Connors, pp. 293-294, development of te J75 began in early 1952, while that of the T57 begn in early 1953. - BilCat (talk) 06:04, 2 February 2011 (UTC)
