Development

I will research and add content regarding the B-1 bomber relationship. The CFM-56 used on medium sized Airbus and other planes is based on engine cores designed for the B-1 bomber (basically the TF-30 turbofan) with afterburner removed and a SNECMA fan and gearbox added. The strategy here was GE avoiding a potential financial hit when the Carter Administration cancelled the B-1A in 1977, GE had invested money in the engine and repackaging it for Airbus provided a way to recoup the investment, while using SNECMA's fan avoided GE's having to develop one, while, at the same time, getting a European partner which would make it politically more likely that European carriers would select GE's engine package (as opposed to Rolls Royce's) when they bought Airbus planes. I will look for references and then edit the article appropriately.22:25, 11 March 2007 (UTC)Raryel

Sounds plausible, but the B-1 used the F101, not TF30 (which is a PW engine). I'm assuming you made a typo or memory error there, but just wanted to make that clear. - BillCJ 23:28, 11 March 2007 (UTC)

Thanks Bill; you are right. I mis-ID'd the engine. Actually, I also must have missed the little section that does talk about the B-1. I just added an external link to SNECMA's website that is a comparison sheet for the engines. 00:05, 12 March 2007 (UTC)Raryel

It happens to all of us. Anyway, if you have some good sources on the development of the CFM56, I'd love to see it in the article. I look forward to reading what you come up with. - BillCJ 01:02, 12 March 2007 (UTC)

LEAP56

I noticed a redlink to LEAP56 in the article, so I deleted the link. I have also created redirects to this article at CFM International LEAP56 and LEAP56. For now, there is not likely to be much information released on the program. But when there is enough info on the LEAP56 to warrant its own page, I recommend placing it at CFM International LEAP56. - BillCJ 04:00, 12 March 2007 (UTC)

Core

You wrote "The CFM56-5B/5C/7 use essentially the same HP core [...] (source is ESM -Engine Shop Manual)" Would you be able to find out which engine part numbers M89P02 or M88G02 come from? It is an HPT blade, but is smaller than 7b's HPT blades, altough it shares the clear CFM design with recent 3d aerodynamc design.

P&W's involvement in cfm56

Re: aviationtoday com/am/ on tx & ist (new) facilities run by p&w.

Could some one shed some light on p&w's commitment to maintain a product of cfm, otherwise 50/50 partnership of snecma and ge as mentioned on the wikipedia article?67.86.58.205 (talk) 22:21, 25 April 2009 (UTC)wikici
