[edit] SNECMA involvement with the F108

Can anyone confirm something I suspect but do not know: I suspect that the F108 does not have as much or any SNECMA content as a standard CFM56. Is this true? —Joseph/N328KF (Talk) 15:26, 18 April 2006 (UTC)

It's the same engine same content, the core of the engine is GE USA, the compressor is Snecma France. Don Pries--Dpries123 18:20, 25 January 2007 (UTC)

[edit] 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)

[edit] 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)
