Boeing has launched a new interior and upgraded CFM engine for the 737 Next Generation family of narrowbody of aircraft.
CFM plans to introduce the CFM56-7B Evolution engine in conjunction with a new interior to deliver a 1% improvement in overall aircraft efficiency. Boeing will also make minor tweaks to the aerodynamics of the aircraft to contribute to a 1% improvement as well.
CFM and Boeing will introduce changes to the engine nozzle and plug, and remove 9% of engine airfoils to reduce maintenance costs by an expected 4%. CFM will also deliver the improvement by increasing airflow through the engine and reducing overall temperature.
The technology changes represent a $100 million investment for CFM.
Overall, Boeing hopes to deliver around 2% of overall improvements for 737 Next Generation customers.
Launch customers include FlyDubai, Continental Airlines, Malaysian Airlines, Tui, Norwegian and GOL.
Entry into service for the engine and aerodynamic enhancements are scheduled for mid-2011. The new interiors will enter service in mid-2010.
CFM will flight test the CFM56-7B Evolution on General Electric's Boeing 747-100 in February of 2010. Boeing will utilise a Continental 737-800 to flight test the changes at the end of 2010 ahead of entry into service.
Once certified the Evolution engine will be designated as the CFM56-7BE.
