SINGAPORE -- CFM56 Tech Insertion has had a highly successful entry into service, with the engines performing extremely well in airline operation. To date, CFM has delivered more than more 900 new CFM56-5B and CFM56-7B engines in this configuration to airlines around the globe.
CFM International (CFM) is a 50/50 joint company between Snecma (SAFRAN Group) and General Electric Company. CFM is the world's leading aircraft engine manufacturer, with nearly 17,600 engines delivered to date.
Tech Insertion became the new production standard for the CFM56-7B and CFM56-5B in 2007. The CFM56-7B variant entered service with Lion Air last May, while Italy's Air One took delivery of the first CFM56-5B Tech Insertion engine in October.
The CFM56 Tech Insertion program incorporates advanced technologies developed and validated as part of Project TECH56 to provide operators with lower maintenance costs. Improved analytic design tools developed as part of this program have enable CFM to further optimize the Tech Insertion combustor so that it will provide 25 percent lower NOx emissions, allowing the engine to meet the new International Civil Aviation Organisation (ICAO) Committee of Aviation Environmental Protection emissions standards (CAEP /6) scheduled to take effect in 2008. In addition, the engine's improvement in fuel consumption will also lower CO2, reducing these emissions by as much as 200 tons per aircraft per year.
Over the engine's life cycle, CFM56 Tech Insertion will also provide operators with longer time on wing through an equivalent 15 - 20 degrees C additional exhaust gas temperature margin and will lower maintenance costs by between five and 12 percent, depending on the thrust rating, through enhanced durability. These benefits are achieved through improvements to the high-pressure compressor and the high- and low-pressure turbines. The new configuration is designated by a "/3" on the engine name place (i.e. CFM56-5B5/3).
