Rising fuel prices are increasing pressure on manufacturers to improve engine efficiency. Geoff Hearn looks at how IAE and CFM are reacting to the problem.
The struggle between engine manufacturers CFM International
and IAE is as keenly fought as that between Boeing and Airbus.
As with the airframe manufacturers, fuel efficiency is always a
key area of competition and now more than ever.
The two engine manufacturers make claim and counter claim,
but most airlines believe that IAE's V2500 can be more fuel
