Maybe time to revisit this old chestnut of a thread... but from the single-aisle/narrowbody perspective.
So, whats the recent goings on?
1. Airbus decide to re-engine A320 with the
geared turbofan from P&W (GTF) and the CFM LEAP-X.
2. Airbus quickly
acquire
many orders for said New Engine Option (NEO).
3. Boeing also consider
re-engining the 737, but hit a snag, the GTF won't fit under the existing aircraft without landing gear mods. Apparently the CFM will.
4. All NEO orders that have
selected an engine so far have
selected the GTF.
Indicative of a significant performance gap?
5. Airbus decide to bring
forward the NEO
introduction, from 2016 to 2015.
6. Airbus decide to
extend the slated A30X
introduction, from 2025 to 2030.
7. Boeing decide.... ?
Meanwhile COMAC and Irkut are developing competitors, both scheduled for introduction in the 2014-2016 timeframe.
Interesting times.
