France- Jet engine makers CFM, Pratt battle over performance

(MENAFN- The Peninsula) Engine makers for next-generation Airbus and Boeing narrow-body jets stepped up their war of words yesterday, claiming their new power plants will burn less fuel, last longer without maintenance and create less noise than the rival. CFM International, the engine maker for about three-quarters of the orders for next-generation Airbus and Boeing narrow-body jets, said its LEAP engine will deliver 15 percent lower fuel burn and 2-3 percent lower operating costs compared with the rival geared turbofan engine by Pratt & Whitney.
