[edit] 3 spool designs

What is the advantage in terms of efficiency of the three spool design versus the two spool design which is used by everyone else

See Rolls-Royce Trent

[edit] RR 1971

I don't remember a large loan to RR from the US government - much more significantly I DO remember RR going bust and having to be nationalised (RR (1971) Ltd) by Mr Heath's Tory government - I have added. Linuxlad 14:34, 8 Jun 2005 (UTC)

What is the source on the US government loan?

I don't believe there was a loan to RR from the US government. However, if the Brisish government was going to rescue RR and complete development of the RB211, the last thing it wanted was for Lockheed (which was not in a strong financial position) itself to fail as this would have killed the L-1011 project and with it the market for the RB211. So the British government insisted that the US government underwrite the bank loans that Lockheed needed to complete the L-1011 project (around £250million).--JCG33 19:03, 31 December 2006 (UTC)

[edit] Notation

How is RB211 meant to be written? With or without the full stop (as in RB.211). Rolls-Royce don't use the . on their website.

I think it should be without the stop. As you say R-R themselves don't use it, neither does Peter Pugh in "The Magic of a Name: The Rolls-Royce Story". Also, the Wiki article on the RB199 doesn't have a stop. On that basis I've removed them from this article.--JCG33 22:21, 30 December 2006 (UTC)

[edit] Unsnubbered?

"the E4 was the first engine to incorporate a wide chord, unsnubbered, fan to improve efficiency. "

Unsnubbered? Ummm, does anyone have an alternate word here? I tried to find a definition, but every one I found has to do with electronics. Maury 13:24, 6 November 2006 (UTC)

A snubber is a damper used to prevent blade flutter. So presumably unsnubbered could be said to be undamped?--JCG33 21:00, 17 January 2007 (UTC)
