American twins,Brit triple spool engines?
Hi Guys,
While I was reading up on jet engines used on airliners,I've realised that most of the American built engines like the GE CF6, GE90 and the Pratt and Whitney PW4000 are all twin spool engines whereas those of the Rolls Royce Trent Series are three spool engines.
Thus,is there a reason as to why the Americans tend to favour twin spool engines over triple spool engines?What are the advantages of the twin spool and the triple spool engines?
Would really appreciate if you guys could shed some light on this.Thanks.
