rr engines are mainly triple spool engines, as opposed to the two spool set up on a p&w or ge engine. on a 777/a330 the rr set will typically weigh 5 tons more than 2 spool engine, but once at cruise the rr is massively economical. so rr have grown into a niche market place over the decades. they were involved in the v2500 set up that was a power option on the a320 narrow body, but the cfm 56 knocked it into a ****ed hat. i’m sure rr have the excellence to get into the sh market, but a massive commitment for the long term. turbofan seems to have a great feel for what’s needed and what’s possible. let’s see.
