CF34-10E Engines Outperforming Expectations

ST. LOUIS, MO -- The CF34-10E engine is beating GE's expectations for time on wing, with outstanding exhaust gas temperature (EGT) margin retention.

"The CF34-10E engine is still early in its lifecycle, but we are excited about its performance to date," said Kathy MacKenzie, general manager of Regional Engines and Services at GE Aviation. "The engine is lasting 20 percent longer on wing to its firstshop visit, which means operators are flying the engine up to 18,000 flight hours before removing it from their aircraft wings."

Along with longer time on wing, the CF34-10E engine has a significant retention if its EGT margin. This is providing operators with a $300,000 fuel savings per aircraft.

The CF34-10E engine entered service in 2005 and holds the highest thrust rating for a CF34 engine at 20,000 pounds of thrust. More than 1,400 CF34-10E engines are in service with more than 60 operators of Embraer's E190/195 aircraft and the EMBRAER Lineage 1000 business jet. The engines have accumulated more than 13 million flight hours and 9 million cycles.

Developed with GE's revenue sharing partners, Ishikawajima-Harima Heavy Industries Co., LTD (IHI) of Tokyo, Japan and Techspace Aero S.A. (TA) of Liege, Belgium, the engine has advanced technology features including: a highly efficient three-dimensional aerodynamic (3-D aero) high-pressure compressor; a low-emission single annular combustor (SAC); a low-solidity high-pressure turbine in which efficiency is improved and the number of airfoils is reduced; and a chevron exhaust nozzle that reduces jet noise.More than 6,000 CF34 engines have been delivered, and GE has continuously invested in product enhancements since the first engine entered service in 1992. Today, CF34 engines are in service with 150 operators in more than 60 countries. The engines have accumulated more than 100 million flight hours and 80 million cycles on Bombardier CRJ and Embraer E-Jet aircraft.
